Emniyet
Kısa zincirli CP'ler kalıcı olarak sınıflandırılır ve fiziksel özellikleri (oktanol-su bölme katsayısı (logKOW) 4,4-8, klorlama derecesine bağlı olarak) biyoakümülasyon için yüksek bir potansiyele işaret eder. Ayrıca, SCCP'ler suda yaşayan organizmalar için toksik ve sıçanlar ve fareler için kanserojen olarak sınıflandırılır. Bu nedenle SCCP'lerin PBT ve vPvB özelliklerine sahip olduğu sonucuna varılmış ve REACH Tüzüğü kapsamında İzin için çok yüksek önem arz eden maddeler Aday Listesine eklenmiştir. [13] SCCP'ler (ortalama zincir uzunluğu C12, klorlama derecesi ağırlıkça% 60), Uluslararası Kanser Araştırma Ajansı'ndan (IARC) grup 2B'de insanlar için muhtemelen kanserojen olarak kategorize edildi. [14] 2017'de, Aralık 2018'den itibaren geçerli olmak üzere Kalıcı Organik Kirleticiler Hakkındaki Stockholm Sözleşmesi kapsamında SCCP'lerin küresel olarak yasaklanmasına karar verildi. Bununla birlikte, MCCP'ler de su ortamı için toksiktir ve kalıcıdır; Toprak, biyota ve sediman çekirdeklerinin çoğundaki MCCP'ler, son yıllardan on yıllara kadar artan zaman trendleri göstermektedir; Yerel kaynaklara yakın tortudaki MCCP konsantrasyonları, PNEC gibi toksisite eşiklerini aşar.

Production of Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)
Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s are synthesized by reaction of chlorine gas with unbranched paraffin fractions (<2 % isoparaffins, <100 ppm aromatics) at a temperature of 80-100 °C.[2] The radical substitution may be promoted by UV-light.[3][1]
CxH(2x+2) + y Cl2 → CxH(2x-y+2)Cly + y HCl
When the desired degree of chlorination is achieved, residues of hydrochloric acid and chlorine are blown off with nitrogen. Epoxidized vegetable oil, glycidyl ether or organophosphorous compounds may be added to the final product for improved stability at high temperatures.[4][5]
Commercial products have been classified as substances of unknown or variable composition. CPs are complex mixtures of chlorinated n-alkanes containing thousands of homologues and isomers[6] which are not completely separated by standard analytical methods.[7]
CPs are produced in Europe, North America, Australia, Brazil, South Africa and Asia.[8] In China, where most of the world production capacity is located, 600,000 tons of Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s were produced in 2007.[9] Production and use volumes of CPs exceeded 1,000,000 tons in 2013.[10]
Industrial applications Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)
Production of CPs for industrial use started in the 1930s.[11] Currently, over 200 CP formulations are in use for a wide range of industrial applications, such as flame retardants and plasticisers, as additives in metal working fluids, in sealants, paints, adhesives, textiles, leather fat and coatings.[12][1]
Safety
Short-chain CPs are classified as persistent and their physical properties (octanol-water partition coefficient (logKOW) 4.4-8, depending on the chlorination degree) imply a high potential for bioaccumulation. Furthermore, SCCPs are classified as toxic to aquatic organisms, and carcinogenic to rats and mice. Therefore, it was concluded that SCCPs have PBT and vPvB properties and they were added to the Candidate List of substances of very high concern for Authorisation under REACH Regulation.[13] SCCPs (average chain length of C12, chlorination degree 60 wt%) were categorised in group 2B as possibly carcinogenic to humans from the International Agency for Research on Cancer (IARC).[14] In 2017, it was agreed to globally ban SCCPs under the Stockholm Convention on Persistent Organic Pollutants, effective December 2018. However, also MCCPs are toxic to the aquatic environment and persistent; MCCPs in soil, biota, and most of the sediment cores show increasing time trends over the last years to decades; MCCP concentrations in sediment close to local sources exceed toxicity thresholds such as the PNEC.

Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s are slowly absorbed by the dermal route in Sprague-Dawley rats. Two (14)C-labeled Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s, C18;50-53% Cl (CP-LH) and C28;47% Cl (CP-LL), were applied to rat skin (5-7 animals of each sex) at a concentration of 66 mg/sq cm, approximately equivalent to 2000 mg/kg body weight. Only 0.7% (males) and 0.6% (females) of the C18 dose was absorbed after 96 hr. Only 0.02% of the C28 dose was absorbed in males whereas in females the level was not detectable. This indicates that increasing chain length leads to decreased permeability. Of the absorbed C18 dose, 40% was exhaled as (14)C-labeled CO2, and 20% was excreted in urine and 20% in feces. /Long chain length Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s/
The absorption of two Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s through human skin has been studied in vitro. There was no absorption of Cereclor S52 (C14-19;52% Cl, CP-MH) following a 54-hr application to the surface of the epidermal membranes using five different receptor media. Similarly, using Cereclor 56L (C10-13; 56% Cl, CP-SH; 18.5% w/w solution in a typical cutting oil) no absorption was detected for 7 hr, but after 23 hr a slow but steady rate of absorption was detected (e.g., 0.05 +/- 0.01 ug/sq cm per hr +/- SEM; n = 6; receptor medium PEG-20 oleyl ether in saline), which was maintained for the duration of the experiment (56 hr). Owing to the anticipated low rate of absorption, the Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin) samples were spiked with [(14)C] n-pentadecane and [(14)C] n-undecane for Cereclor S52 and 56L, respectively, in order to facilitate detection of the absorbed material. Measurement of the (14)C-alkanes was taken as a surrogate for the Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s, on the assumption that their rates of absorption were similar.
Female C57Bl mice were administered 12.5 MBq/kg body weight (340 uCi) (for autoradiography) or 1.25 MBq/kg body weight (34 uCi) (for determination of radioactivity) of (14)C-labeled chlorododecanes (C12) with different chlorine contents (17.5% [CP-SL], 55.9% [CP-SH] and 68.5% [CP-SH]) either by gavage or intravenous injection. Uptake of radioactivity was found by autoradiography to be highest in tissues with high cell turnover/high metabolic activity, e.g., intestinal mucosa, bone marrow, salivary glands, thymus and liver. The highest radioactivity was achieved with the Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin) that had the lowest chlorine content. It was found that the long period of retention of heptane-soluble radioactivity, which indicated unmetabolized substance, in liver and fat after oral dosing increased with degree of chlorination. In this study it was also found that 30 to 60 days after injection of C12;17.5% Cl and C12;55.9% Cl a considerable retention of radioactivity was seen in the central nervous system. Exposure of late gestation mice showed a transplacental passage of radioactivity, and (14)C-labeling was primarily noted in the liver, brown fat and intestine of the fetuses. /short chain length Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)/

 

 

(14)C-Labeled [1-(14)C]polychlorohexadecane (C16;34.1% Cl, CP-ML) was given to C57Bl mice either by gavage (females) or intravenously (both sexes) at a radioactivity level of 370 kBq/animal (10 uCi) (corresponding to 0.44 umol of the Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)). No difference in the distribution patterns was found between the oral and intravenous administration routes. After analysis by autoradiography a high level of radioactivity was found in tissues with a high cell turnover rate and/or high metabolic activity, and lower levels could be seen in the white fat depots. High levels of radioactivity were observed in the liver, kidneys, spleen, bone marrow, brown fat, intestinal mucosa, pancreas, salivary gland and the Harderian gland 24 hr after intravenous injection. After 12 days high levels of radioactivity were seen in the adrenal cortex, abdominal fat and in the bile. Later after injection (30 days), prominent radiolabeling of the brain was found which was as high as in the liver. The Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin) was also administered intravenously to pregnant mice, and uptake of radioactivity in the fetuses was observed. When the mice were administered on day 10 of pregnancy no tissue-specific localization was found, but after administration in late pregnancy (day 17) the distribution pattern after 6 hr was similar to that of adult mice when examined 24 hr after administration. /Intermediate chain length Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)/
/It was/ demonstrated that inducers and inhibitors of cytochrome P-450 (CYP) affect the rate of degradation of (14)C-labeled polychlorinated dodecanes (C12) containing 68.5% (CP-SH), 55.9% (CP-SH) and 17.4% Cl (CP-SL) to (14)CO2 in exposed C57Bl mice. Pretreatment with the inhibitor piperonyl butoxide decreased the amount of (14)CO2 formed, and the decrease was more pronounced with increasing degree of chlorination. The inhibitor metyrapone decreased the exhalation of (14)CO2 but was only investigated in mice exposed to C12;68.5% Cl. The cytochrome P-450 (CYP2B1; CYP2B2) inducer, phenobarbital, moderately increased the rate of (14)CO2 formation from Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin) with 68% Cl, whereas the P-448 (CYP1A1; CYP1A2) inducer, 3-methylcholanthrene, did not affect the degradation rate, indicating a cytochrome P-450-dependent metabolism of chlorinated dodecanes yielding (14)CO2. /Short chain length Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)/

No data were available from studies in humans on the carcinogenicity of Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s. Overall evaluation: Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s of average carbon-chain length C12 and average degree of chlorination approximately 60% are possibly carcinogenic to humans (Group 2B).
/LABORATORY ANIMALS: Acute Exposure/ The eye irritation potential of three different Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s, C10-13;65% Cl(CP-SH), which contained either 2.5 or 2% of two different additives or 0.7% of an epoxy stabilizer, was tested in two studies. Either 0.1 mL or "one drop" of the chloroparaffin was instilled into one conjunctival sac of groups of three rabbits. Similar results were reported for all three formulations: practically no initial pain (2 on a 6-point scale) was noted. Slight irritation (3 on a 8-point scale), shown by redness and chemosis (only noted in the formulation containing the epoxy stabilizer) of the conjunctiva with some discharge, lasted for 24 hr. One drop of 52% or 40% Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s, containing unspecified additives or 1% epoxy stabilizer, was also tested. With the 52% Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin), slight immediate irritation was followed by slight redness of the conjunctiva which lasted for 24 hr.

Toxicology and carcinogenesis studies of Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s (C23, 43% chlorine) ... were conducted by administering the chemical in corn oil by gavage to groups of 50 F344/N rats and 50 B6C3F1 mice of each sex, 5 days per week for 103 wk. Additional groups of 10 rats per sex and dose were examined at 6 and at 12 months. Male rats received doses of 0, 1,875, or 3,750 mg/kg body weight; female rats were given 0, 100, 300, or 900 mg/kg. Male and female mice received 0, 2,500, or 5,000 mg/kg. Doses selected for the 2 yr studies were based on the results from 13 wk studies in which rats of each sex received 0 to 3,750 mg/kg, and mice of each sex, 0 to 7,500 mg/kg. Under the conditions of these 2 yr gavage studies, there was no evidence of carcinogenicity of Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s (C23, 43% chlorine) for male F344/N rats given 1,875 or 3,750 mg/kg per day. There was equivocal evidence of carcinogenicity of Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s (C23, 43% chlorine) for female F344/N rats as shown by an increased incidence of adrenal gland medullary pheochromocytomas. There was clear evidence of carcinogenicity of Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s (C23, 43% chlorine) for male B6C3F1 mice as shown by an increase in the incidence of malignant lymphomas. There was equivocal evidence of carcinogenicity of Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s (C23, 43% chlorine) for female B6C3F1 mice as shown by a marginal increase in the incidence of hepatocellular neoplasms.

Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s' production and use as extreme pressure lubricants, fire retardant additives and sealants for C10-C13 (50-70% chlorinated), secondary PVC plasticizers for C14-C17 (45-60% chlorinated) and paints, extreme pressure lubricants and fire retardant additives for C20-C30 (40-70% chlorinated) may result in their release to the environment through various waste streams. If released to air, a vapor pressure on the order of 2X10-5 mm Hg indicates Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s will exist in both the vapor and particulate phases. Vapor-phase Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals. Particulate-phase Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s will be removed from the atmosphere by wet or dry deposition. Sunlight appears to catalyze the decomposition of Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s with the evolution of hydrogen chloride. If released to soil, Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s are expected to have no mobility based upon estimated Koc values of 5900 to 2.2X10+8. Volatilization from moist soil surfaces is not expected to be an important fate process based upon the low vapor pressure of 2X10-5 mm Hg and extremely low water solubility. Based on limited biodegradation studies, Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s may biodegrade in soil and water. If released into water, Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s are expected to adsorb to suspended solids and sediment based upon the estimated Koc values. Volatilization from water surfaces is not expected to be an important fate process based upon the vapor pressure and water solubility. A log BCF of 1.69, and BCF values of 7800 in fresh water fish suggest bioconcentration in aquatic organisms is moderate to very high. Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s are not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions. Occupational exposure to Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s may occur through dermal contact with this compound at workplaces where Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s are produced or used. Use and monitoring data indicate that the general population may be exposed to Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s via ingestion of food and dermal contact with products containing Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s.

TERRESTRIAL FATE: Based on a classification scheme(1), estimated Koc values of 5900 to 2.2X10+8(SRC), determined from log Kows of 4.4 to 12.8(2) and a regression-derived equation(3), indicate that Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s are expected to be immobile in soil(SRC). Volatilization of Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s from moist soil surfaces is not expected to be an important fate process(SRC) based upon the low vapor pressure of 2X10-5 mm Hg and extremely low water solubility(4). Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s are not expected to volatilize from dry soil surfaces(SRC) based upon the vapor pressure(4). Based on limited biodegradation studies Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s may biodegrade in soil(5-6).
NIOSH (NOES Survey 1981-1983) has statistically estimated that 573,193 workers (38,354 of these were female) were potentially exposed to Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s in the US(1). Occupational exposure to Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s may occur through dermal contact with this compound at workplaces where Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s are produced or used.

Uses of Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s :
Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s are used as secondary plasticizers for polyvinyl chloride (PVC) and can partially replace primary plasticizers such as phthalates and phosphate esters.
The use of Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s has the advantage in comparison with conventional plasticizers of both increasing the flexibility of the material as well as increasing its flame retardancy and low-temperature strength. Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s are also used as extreme pressure additives in metal- machining fluids or as metal working lubricants or cutting oils because of their viscous nature, compatibility with oils, and property of releasing hydrochloric acid at elevated temperatures. The hydrochloric acid reacts with metal surfaces to form a thin but strong solid film of metal chloride lubricant. They are added to paints, coatings and sealants to improve resistance to water and chemicals, which is most suitable when they are used in marine paints, as coatings for industrial flooring, vessels and swimming pools (e.g., rubber and chlorinated rubber coatings), and as road marking paints.
The flame-retarding properties of highly Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s make them important as additives in plastics, fabrics, paints and coatings. The most effective fire-retardant action is obtained with a high degree of chlorination. By the late 1970s approximately 50% of Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s in the USA was used as extreme pressure lubricant additives in the metal-working industry; 25% was used in plastics and fire-retardant and water- repellant fabric treatments, and the rest was used in paint, rubber, caulks and sealants In the United Kingdom, 65-70% of the consumed Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin)s is used as a secondary plasticizer in PVC, about 10% in paint, about 10% in metal-cutting lubricants and about 10% in flame retardants and sealants

 

 

Textile and Tanning Auxiliaries:
Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin) can be used as additive in the treatment of textiles, in particular for fireproof finishing and In combination with chlorinated polyethylene or chlorinated rubber for waterproofing natural fiber fabrics by impregnation and synthetic fibers by smearing. Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin), due to their polar nature, are also used as greasing agents for hides and similar raw materials.
Others:
Because of their full compatibility, low volatility, good stability and non flammability, the various types of Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin) are used as plasticizers in the preparations of solvent and emulsion paints and varnishes. Adding Chlorinated Paraffin (CHLORINATED PARAFFIN, CP, Klorlu Parafin) to paints or varnishes increases their hardness, brilliancy and resistance to acids and alkalis and improves the elasticity of the final product.

 

 


Paraffines Chlorée (CHLORINATED PARAFFIN, CP, Klorlu Parafin)

 

 

Les chloroalcanes, chlorures d'alkyle ou paraffines chlorées font partie de la famille des halogénoalcanes (dérivés halogénés des alcanes).
Ce sont des alcanes (paraffines), produits depuis les années 19901, dont un ou plusieurs atomes d'hydrogène ont été remplacés par des atomes de chlore ; ils sont notamment utilisés comme retardateur de flamme et additifs d'huile de coupe, apprêts pour cuir ou textiles1 en partie pour remplacer les polychlorobiphényles (PCB) interdits depuis 19801.
Certains d'entre eux sont des toxiques et cancérigènes avérés. En particulier les paraffines chlorées à chaînes courtes (SCCP ou PCCC) font partie des 87 espèces chimiques dites "substances prioritaires" qui en Europe avant 20202, doivent faire l'objet d'une réduction des rejets, des émissions et des pertes1.
Leur consommation a selon l'INERIS fortement diminué depuis la fin du xxe siècle, mais ce sont des produits souvent très stables dans l'environnement où ils peuvent s'être accumulés et/ou être bioconcentrés par certaines espèces[réf. nécessaire]. Certains sont aussi des perturbateurs endocriniens1. Ce sont des polluants notamment retrouvés dans les sédiments et le milieu marin3.
Fabrication, production
Les chloroalcanes (= paraffines chlorées) sont un mélange de n-alcanes polychlorés, issus de la réaction de chlore sur certaines fractions de paraffines issues de la distillation du pétrole4. Les chloroalcanes mis sur le marché sont surtout des molécules comprenant 10 à 30 atomes de carbones (C10 à C30), avec un taux de chlore total compris entre 40 et 70 %.
Les PCCC ne sont plus produits en France.
À partir de 2004, ils n'auraient plus dû y être utilisés, sauf comme plastifiants et/ou comme retardateurs de flamme dans des peintures et certains caoutchoucs.
Typologie
Les chimistes distinguent
les chloroalcanes à chaîne courte (C10-C13), dits "paraffines chlorées à chaîne courte" (PCCC).
les chloroalcanes à chaîne moyenne (C14-C17)
les chloroalcanes à chaîne longue (C18-C20)
...et les cires en C24. Dans les 3 premiers cas, les produit sont souvent un mélanges de molécules de différentes longueurs de chaîne carbonée et donc présentant différentes taux de chloration.

 

 

Paraffines chlorées à chaîne courte (C10-C13 - PCCC)
Ils intéressent essentiellement le commerce et l'industrie, mais sont très toxiques : la directive 98/98/CE 6 les a classé en substances dangereuses pour l'environnement, nocives et cancérogènes (de catégorie 3), puis Le règlement (CE) n°1272/2008 (CLP) les a classé en substances dangereuses prioritaires pour l'environnement (toxicité chronique et aigüe de catégorie 1) et cancérogènes de catégorie 2.
Les PCCC vendus sont rarement purs ; il s'agit le plus souvent des mélanges de molécules de différentes longueurs de chaîne carbonée, avec différents taux de chloration. Le numéro CAS le plus courant pour les désigner est le CAS:85535-84-8.
D'après Euro Chlor et l'INERIS au début des années 2000, ces produits n'étaient plus fabriqués en France et de moins en moins utilisés en Europe, mais en 2011 Ineos ChlorVinyls (autrefois ICI Chlor-Chemicals) en commercialise encore (sous le nom de Cereclor).
Depuis 2004, ils ne devraient plus être utilisés en France que comme plastifiants et comme retardateurs de flamme dans certaines peintures et caoutchoucs. Des substituts variés existent déjà pour la plupart des utilisations, souvent déjà utilisés depuis le début des années 2000, mais ces produits étant appréciés comme agents d'ignifugeant, leur élimination sera difficile selon l'INERIS4.
Paraffines chlorées à chaîne moyenne (C14-C17)
D'après Euro Chlor, la France en produit encore en 2011. Comme celles à chaîne longue, ces paraffines sont utilisés pour usiner les métaux (ex : « Cereclor E » ).

Paraffines chlorées à chaîne longue (C18-C30)
Ces paraffines chlorées sont utilisées pour usiner les métaux.
Des paraffines chlorées C6-C30 sont utilisées comme agent de graissage des cuirs, mais ne sont plus utilisées comme retardateurs de flamme dans le cuir depuis quelques années, selon les fabricants5.

Classification
les chloroalcanes doivent être "rapportées" par les industriels dans l'Union Européenne comme substances HPV (high production volume) 6.
Ils ont été classés dans la liste prioritaires d'évaluation du programme européen des substances existantes7 et en tant que tel on subi une première évaluation de risques8.
Les PCCC sont classées parmi les polluants organiques persistants « POPs » par le règlement (UE) No 519/2012 ;
ils ne sont pas cités par la stratégie communautaire sur les perturbateurs endocriniens 9 ;
ils ne figurent pas dans l'annexe I du règlement 649/2012 relatif à l'export et l'importation de substances dangereuses10.
Usages et tonnages
Des PCCC ont beaucoup été utilisés comme plastifiants secondaire (par exemple : Alaiflex de Rhodia, utilisé pour diminuer les taux de DEHP, plus coûteux, dans le PVC), comme fluide d'usinage de métaux, retardateur de flamme (ex : Cereclor 50LV, 60L, 63L et 65L utilisé pour ignifuger des textiles et des PCCC hautement chlorées, contenant de 63 à 71 % de leurs poids en chlore ont été ou sont utilisées comme retardateurs de flamme pour des caoutchoucs, souvent en complément de trioxyde d'antimoine ou d'hydroxyde d'aluminium, à des taux variant de 1 à 10 %11), imperméabilisation de textiles, dans des Peintures, mastics et adhésifs Interdiction et pour le traitement des cuirs4, pour l'usinage de métaux12 alors qu'en 1994 l'industrie du métal en consommait (au moins 2 800 tonnes/an13) et rejetait encore selon Euro Chlor, .

 

 

La plupart de leurs usages ont été interdits à partir de la fin des années 1995 dans les pays riches, mais leurs utilité pour l'ignifugation rend difficiles à éliminer les paraffines chlorées à chaîne courte4.
Les paraffines chlorées à chaîne courte été très utilisées autrefois : par exemple en France avec plusieurs milliers de tonnes par an au début des années 1990 et en Europe (13 000 tonnes environ en 1994, pour encore 4 000 tonnes en 1998)14.
Toxicité, écotoxicité
Les chloroalcanes C10-C13 également dits paraffines chlorées à chaîne courte ou PCCC), sont considérés comme toxiques, et pour beaucoup cancérigènes15,16,1,17,18.
Les fabricants réunis dans Euro Chlor ont eux-mêmes reconnus la toxicité des PCCC et proposé un retrait volontaire de ces produits du marché19.
Les chloroalcanes C14-C17 sont considérés comme beaucoup moins toxiques et ne sont pas sujets à restrictions.
Les chloroalcanes C18-C30 sont considérés comme non toxiques (aucune classification selon l'Union européenne).

 

 

Vers une interdiction totale?
En 1995, la commission OSPAR exige20 l'abandon par les Etats-membres avant 1999, de l'utilisation des paraffines chlorées à chaîne courte comme plastifiants dans les peintures et les revêtements, comme plastifiants dans les produits d'étanchéité, dans les fluides de travail des métaux et comme agent ignifuge (retardateurs de flamme) dans le caoutchouc, les matières plastiques et les textiles (hormis pour quelques applications concernant les barrages et les mines, où une dérogation autorisait une utilisation jusque fin 2004).
En 2002, La directive 2002/45/CE interdit la mise sur le marché de produits contenant des concentrations en chloroalcanes en C10-C13 supérieures à 1% pour l'usinage des
métaux et le graissage du cuir. En outre elle exige qu'avant le 1er janvier 2003, toutes les utilisations restantes des paraffines chlorées à chaîne courte soient réexaminées par la Commission, en coopération avec les États membres et la commission OSPAR, à la lumière de toute nouvelle donnée scientifique pertinente concernant les risques présentés par les paraffines chlorées à chaîne courte pour la santé et l'environnement21.
En 2003, en France un décret 22 transcrit la directive citée ci-dessus (directive 2002/45/CE) ; il interdit toute mise sur le marché de préparations pour l'usinage des métaux ou le graissage du cuir contenant des concentrations en paraffines chlorées à chaîne courte supérieures à 1 %, à partir du 1er janvier 2004.
Alternatives
Des substituts existent (produits sulfo-chlorés ou non chlorés, voire non halogénés) pour la plupart de leurs utilisations. Ils les ont déjà souvent remplacés, au moins dans les pays pour lesquels des données sont disponibles.
Des esters alkyl phosphate ou des esters acides gras sulfonatés peuvent ainsi être utilisés pour usiner les métaux23.
Des esters phtalate, esters polyacryliques, des composés de diisobutyrate ou de phosphate ou de bore peuvent être utilisés comme plastifiant avec autres problèmes peut-être, dont pour les phtalates (perturbateurs endocriniens)24.
Les effets sanitaires et plus encore écologique d'une partie des produits alternatif sont cependant encore mal connus ; Des substituts soufrés ou bromés pourraient être plus toxiques encore que les PCCC (le pentabromodiphényléther (PBDE) ou l'octabromodiphényléther, autres retardateurs de flamme sont aussi classés substances dangereuses prioritaires). Ceux à base de phosphore posent des problèmes pour le milieu aquatique en cas de rejet, etc.

 

 

Quantification analytique
Les SCCPs sont des mélanges complexes comportant généralement plusieurs milliers d'isomères de position ne pouvant être séparés par les techniques analytiques disponibles (chromatographie notamment), faisant qu'en 2014, aucune méthode fiable de dosage n'existe encore, ni de principes permettant de justifier le choix de molécules représentatives (et donc l'étalonnage d'un appareil de mesure) d'un mélange (comme dans le cas des PCBs) ; le choix du détecteur et de la méthode de purification de l'échantillon à analyse est également délicat1. La marge d'erreur induite par un mauvais choix d'étalon en chromatographie peut dépasser 60%1.

 

 

Dépollution
Parmi les solutions à l'étude Obeid en (2014) a proposé d'utiliser des matériaux magnétiques pour les adsorber et les extraires de milieux liquides contaminés1.

Parce qu'il est économique, il permet des économies par rapport aux plastifiants primaires.
La paraffine chlorée (PARAFFINE CHLOREE, CP, Klorlu Parafin) n'a pas d'odeur douce et désagréable caractéristique. L'odeur est probablement due à de petites quantités de masse moléculaire relativement faible avec une pression de vapeur faible mais mesurable. La longueur de la chaîne carbonée et la teneur en chlore de la paraffine déterminent les propriétés chimiques et physiques de la paraffine chlorée (CHLORINATED PARAFFIN, CP, Klorlu Parafin). Il augmente la longueur de la chaîne carbonée et les degrés de chloration de certaines paraffines augmentent la viscosité et la densité, mais réduit la volatilité. La paraffine chlorée (PARAFFINE CHLOREE, CP, Klorlu Parafin) contient normalement des stabilisants qui sont ajoutés pour empêcher la dégradation. Les stabilisants courants comprennent les esters époxydés et les composés époxydés tels que les huiles de soja, le pentaéritritol, le thymol, l'urée, les acétonitriles et les phosphates organiques.

Applications industrielles Paraffine chlorée (PARAFFINE CHLOREE, CP, Klorlu Parafin)
La production de PC à usage industriel a commencé dans les années 1930. [11] Actuellement, plus de 200 formulations CP sont utilisées pour une large gamme d'applications industrielles, telles que les retardateurs de flamme et les plastifiants, comme additifs dans les fluides de travail des métaux, dans les mastics, les peintures, les adhésifs, les textiles, les graisses de cuir et les revêtements. [12] [1 ]
sécurité
Les PC à chaîne courte sont classés comme persistants et leurs propriétés physiques (coefficient de partage octanol-eau (logKOW) 4,4-8, selon le degré de chloration) impliquent un potentiel élevé de bioaccumulation. De plus, les PCCC sont classés comme toxiques pour les organismes aquatiques et cancérigènes pour les rats et les souris. Par conséquent, il a été conclu que les PCCC avaient des propriétés PBT et vPvB et ils ont été ajoutés à la liste candidate des substances extrêmement préoccupantes pour l'autorisation en vertu du règlement REACH. [13] Les PCCC (longueur moyenne de chaîne de C12, degré de chloration 60% en poids) ont été classés dans le groupe 2B comme potentiellement cancérogènes pour l'homme par le Centre international de recherche sur le cancer (CIRC). [14] En 2017, il a été convenu d'interdire globalement les PCCC en vertu de la Convention de Stockholm sur les polluants organiques persistants, à compter de décembre 2018. Cependant, les PCCC sont également toxiques pour l'environnement aquatique et persistants; Les PCMC dans le sol, le biote et la plupart des carottes de sédiments montrent des tendances temporelles croissantes au cours des dernières années, voire des décennies; Les concentrations de MCCP dans les sédiments à proximité de sources locales dépassent les seuils de toxicité tels que la CESE.

Les paraffines chlorées (PARAFFINE CHLOREE, CP, Klorlu Parafin) sont une classe de produits chimiques utilisés pour une variété d'applications. Ils peuvent être classés en fonction de la longueur de leurs chaînes de chlore, et les formulations commerciales peuvent inclure un mélange de composés de cette classe. CAS 106232-86-4 est considéré comme une paraffine chlorée à longue chaîne (PARAFFINE CHLOREE, CP, Klorlu Parafin) (LCCP), avec 24 atomes de chlore. La forme longue est moins sensible à l'environnement que les variétés courtes.
La paraffine chlorée (PARAFFINE CHLOREE, CP, Klorlu Parafin) est largement inerte, presque insoluble dans l'eau et ignifuge. Il peut fonctionner comme un additif plastifiant pour les lubrifiants métalliques et les fluides de coupe, les plastiques, le caoutchouc, la peinture, les adhésifs, etc. La majeure partie de la paraffine chlorée du monde (CHLORE PARAFFIN, CP, Klorlu Parafin) est produite en Chine
Les paraffines chlorées (PARAFFINE CHLOREE, CP, Klorlu Parafin) sont lentement absorbées par voie cutanée chez les rats Sprague-Dawley. Deux (14) paraffines chlorées marquées C (CHLORE PARAFFIN, CP, Klorlu Parafin) s, C18; 50-53% Cl (CP-LH) et C28; 47% Cl (CP-LL), ont été appliquées sur la peau de rat ( 5-7 animaux de chaque sexe) à une concentration de 66 mg / cm2, soit environ l'équivalent de 2000 mg / kg de poids corporel. Seulement 0,7% (hommes) et 0,6% (femmes) de la dose de C18 ont été absorbés après 96 heures. Seulement 0,02% de la dose de C28 a été absorbée chez les mâles, tandis que chez les femelles, le niveau n'était pas détectable. Cela indique que l'augmentation de la longueur de la chaîne entraîne une diminution de la perméabilité. De la dose de C18 absorbée, 40% ont été exhalés sous forme de CO2 marqué au (14) C, et 20% ont été excrétés dans l'urine et 20% dans les fèces. / Paraffine chlorée longue chaîne (PARAFFINE CHLOREE, CP, Klorlu Parafin) s /
L'absorption de deux paraffines chlorées (PARAFFINE CHLOREE, CP, Klorlu Parafin) à travers la peau humaine a été étudiée in vitro. Il n'y a pas eu d'absorption de Cereclor S52 (C14-19; 52% Cl, CP-MH) après une application de 54 heures sur la surface des membranes épidermiques en utilisant cinq milieux récepteurs différents. De même, en utilisant Cereclor 56L (C10-13; 56% Cl, CP-SH; solution à 18,5% p / p dans une huile de coupe typique), aucune absorption n'a été détectée pendant 7 heures, mais après 23 heures, un taux d'absorption lent mais constant était détecté (par exemple, 0,05 +/- 0,01 ug / cm2 par heure +/- SEM; n = 6; milieu récepteur PEG-20 oléyl éther dans une solution saline), qui a été maintenu pendant la durée de l'expérience (56 heures). En raison du faible taux d'absorption prévu, les échantillons de paraffine chlorée (PARAFFINE CHLOREE, CP, Klorlu Parafin) ont été enrichis de [(14) C] n-pentadécane et de [(14) C] n-undécane pour Cereclor S52 et 56L, respectivement, afin de faciliter la détection du matériau absorbé. La mesure des (14) C-alcanes a été prise comme substitut de la paraffine chlorée (CHLOREE PARAFFIN, CP, Klorlu Parafin), en supposant que leurs taux d'absorption étaient similaires.
Des souris femelles C57Bl ont reçu 12,5 MBq / kg de poids corporel (340 uCi) (pour l'autoradiographie) ou 1,25 MBq / kg de poids corporel (34 uCi) (pour la détermination de la radioactivité) de (14) chlorododécanes marqués au C (C12) avec différents chlore contenu (17,5% [CP-SL], 55,9% [CP-SH] et 68,5% [CP-SH]) soit par gavage soit par injection intraveineuse. L'absorption de radioactivité a été trouvée par autoradiographie comme étant la plus élevée dans les tissus à fort renouvellement cellulaire / activité métabolique élevée, par exemple la muqueuse intestinale, la moelle osseuse, les glandes salivaires, le thymus et le foie. La radioactivité la plus élevée a été obtenue avec la paraffine chlorée (PARAFFINE CHLOREE, CP, Klorlu Parafin) qui avait la plus faible teneur en chlore. Il a été constaté que la longue période de rétention de la radioactivité soluble dans l'heptane, qui indiquait une substance non métabolisée, dans le foie et les graisses après administration orale augmentait avec le degré de chloration. Dans cette étude, il a également été constaté que 30 à 60 jours après l'injection de C12; 17,5% Cl et C12; 55,9% Cl, une rétention considérable de radioactivité a été observée dans le système nerveux central. L'exposition de souris en fin de gestation a montré un passage transplacentaire de la radioactivité, et (14) le marquage C a été principalement noté dans le foie, la graisse brune et l'intestin des fœtus. / Paraffine chlorée à chaîne courte (CHLORE PARAFFIN, CP, Klorlu Parafin) /

 

 

(14) Du [1- (14) C] polychlorohexadécane marqué au C (C16; 34,1% Cl, CP-ML) a été administré à des souris C57Bl soit par gavage (femelles) ou par voie intraveineuse (les deux sexes) à un niveau de radioactivité de 370 kBq / animal (10 uCi) (correspondant à 0,44 umol de la paraffine chlorée (CHLOREE PARAFFIN, CP, Klorlu Parafin)). Aucune différence dans les schémas de distribution n'a été trouvée entre les voies d'administration orale et intraveineuse. Après analyse par autoradiographie, un niveau élevé de radioactivité a été trouvé dans les tissus avec un taux de renouvellement cellulaire élevé et / ou une activité métabolique élevée, et des niveaux inférieurs pouvaient être observés dans les dépôts de graisse blanche. Des niveaux élevés de radioactivité ont été observés dans le foie, les reins, la rate, la moelle osseuse, la graisse brune, la muqueuse intestinale, le pancréas, la glande salivaire et la glande de Harder 24 heures après l'injection intraveineuse. Après 12 jours, des niveaux élevés de radioactivité ont été observés dans le cortex surrénalien, la graisse abdominale et la bile. Plus tard après l'injection (30 jours), un radiomarquage proéminent du cerveau a été trouvé, aussi élevé que dans le foie. La paraffine chlorée (PARAFFINE CHLOREE, CP, Klorlu Parafin) a également été administrée par voie intraveineuse à des souris gravides et une absorption de radioactivité chez les fœtus a été observée. Lorsque les souris ont été administrées au jour 10 de la grossesse, aucune localisation tissulaire spécifique n'a été trouvée, mais après administration en fin de grossesse (jour 17), le schéma de distribution après 6 heures était similaire à celui des souris adultes examinées 24 heures après l'administration. / Paraffine chlorée de longueur de chaîne intermédiaire (PARAFFINE CHLOREE, CP, Klorlu Parafin) /
/ Il a été / a démontré que les inducteurs et les inhibiteurs du cytochrome P-450 (CYP) affectent la vitesse de dégradation des polychlorodécanes (C12) marqués au (14) C contenant 68,5% (CP-SH), 55,9% (CP-SH) et 17,4% Cl (CP-SL) à (14) CO2 chez des souris C57Bl exposées. Un prétraitement avec l'inhibiteur de butoxyde de pipéronyle diminuait la quantité de (14) CO2 formée, et la diminution était plus prononcée avec l'augmentation du degré de chloration. L'inhibiteur métyrapone a diminué l'expiration de (14) CO2, mais n'a été étudié que chez les souris exposées à C12; 68,5% Cl. L'inducteur du cytochrome P-450 (CYP2B1; CYP2B2), le phénobarbital, a modérément augmenté le taux de (14) formation de CO2 à partir de la paraffine chlorée (CHLORE PARAFFIN, CP, Klorlu Parafin) avec 68% Cl, tandis que le P-448 (CYP1A1; CYP1A2) ), le 3-méthylcholanthrène, n'a pas affecté la vitesse de dégradation, indiquant un métabolisme dépendant du cytochrome P-450 des dodécanes chlorés produisant du (14) CO2. / Paraffine chlorée à chaîne courte (PARAFFINE CHLOREE, CP, Klorlu Parafin) /
