PVP K-30 is a hygroscopic, amorphous polyvinylpyrrolidone. Used in industrial, specialty and imaging coatings & paints and as a media component in digital ink jet-printing. Offers high polarity, dispersancy, hydrophilicity, adhesion, cohesivity and high glass transition temperature. PVP K-30 can be plasticized with water and most common organic plasticizers. They are linear nonionic polymers thar are soluble in water and organi solvents and are pH stable. PVP K-30 forms hard glossy transparent films and have adhesive, cohesive and dispersive properties.

PVP K-30 100% Powder is soluble in water and many organic solvents and it forms hard, transparent, glossy film. PVP is compatible with most inorganic salts and many resins. PVP stabilizes emulsions, dispersions and suspensions. While PVP is used as a film former in hair styling products, PVP can also be used as an emulsion stabilizer in creams and lotions and as a dispersant for hair colorants. Additionally, pharmaceutical grade PVP can be used in toothpastes and mouthwashes. PVP K-30 100% Powder appears as a white powder.

Applications

adhesives, ceramics, glass (fibers), coating/inks, electronic appliations, lithography and photography, fibers and textiles, membranes, metallurgy, paper, polymerizations, water and waste teratment, and hygiene.

Polyvinylpyrrolidone (PVP), also commonly called polyvidone or povidone, is a water-soluble polymer made from the monomer N-vinylpyrrolidone:

PVP was used as a plasma volume expander for trauma victims after the 1950s.

It is used as a binder in many pharmaceutical tablets;[2] it simply passes through the body when taken orally. (However, autopsies have found that crospovidone (PVPP) contributes to pulmonary vascular injury in substance abusers who have injected pharmaceutical tablets intended for oral consumption.[3] The long-term effects of crospovidone or povidone within the lung are unknown.)

PVP added to iodine forms a complex called povidone-iodine that possesses disinfectant properties.[4] This complex is used in various products like solutions, ointment, pessaries, liquid soaps and surgical scrubs. It is known under the trade names Pyodine and Betadine, among a plethora of others.

It is used in pleurodesis (fusion of the pleura because of incessant pleural effusions). For this purpose, povidone iodine is equally effective and safe as talc, and may be preferred because of easy availability and low cost.[5]

PVP is used in some contact lenses and their packaging solutions. It reduces friction, thus acting as a lubricant, or wetting agent, built into the lens. Examples of this use include Bausch & Lomb's Ultra contact lenses with MoistureSeal Technology[6] and Air Optix contact lens packaging solution (as an ingredient called "copolymer 845").[7]

PVP is used as a lubricant in some eye drops, Soothe.[8]

Technical

PVP is also used in many technical applications:

as an adhesive in glue stick and hot-melt adhesivesas a special additive for batteries, ceramics, fiberglass, inks, and inkjet paper, and in the chemical-mechanical planarization process

as an emulsifier and disintegrant for solution polymerization to increase resolution in photoresists for cathode ray tubes (CRT)[9] in aqueous metal quenching for production of membranes, such as dialysis and water purification filters

as a binder and complexation agent in agricultural applications such as crop protection, seed treatment and coating

as a thickening agent in tooth whitening gels[10]

as an aid for increasing the solubility of drugs in liquid and semi-liquid dosage forms (syrups, soft gelatine capsules) and as an inhibitor of recrystallisation

as an additive to Doro's RNA extraction buffer[citation needed]

as a liquid-phase dispersion enhancing agent in DOSY NMR [11]

as a surfactant, reducing agent, shape controlling agent and dispersant in nanoparticle synthesis and their self-assembly[12]

as a stabilizing agent in all inorganic solar cells[13]

Other uses

PVP binds to polar molecules exceptionally well, owing to its polarity. This has led to its application in coatings for photo-quality ink-jet papers and transparencies, as well as in inks for inkjet printers.

PVP is also used in personal care products, such as shampoos and toothpastes, in paints, and adhesives that must be moistened, such as old-style postage stamps and envelopes. It has also been used in contact lens solutions and in steel-quenching solutions.[14][15] PVP is the basis of the early formulas for hair sprays and hair gels, and still continues to be a component of some.

As a food additive, PVP is a stabilizer and has E number E1201. PVPP (crospovidone) is E1202. It is also used in the wine industry as a fining agent for white wine and some beers.

In molecular biology, PVP can be used as a blocking agent during Southern blot analysis as a component of Denhardt's buffer. It is also exceptionally good at absorbing polyphenols during DNA purification. Polyphenols are common in many plant tissues and can deactivate proteins if not removed and therefore inhibit many downstream reactions like PCR.

In microscopy, PVP is useful for making an aqueous mounting medium.[16]

PVP can be used to screen for phenolic properties, as referenced in a 2000 study on the effect of plant extracts on insulin production.[17]

Safety

The U.S. Food and Drug Administration (FDA) has approved this chemical for many uses,[18] and it is generally considered safe. However, there have been documented cases of allergic reactions to PVP/povidone, particularly regarding subcutaneous (applied under the skin) use and situations where the PVP has come in contact with autologous serum (internal blood fluids) and mucous membranes. For example, a boy having an anaphylactic response after application of PVP-Iodine for treatment of impetigo was found to be allergic to the PVP component of the solution.[19] A woman, who had previously experienced urticaria (hives) from various hair products, later found to contain PVP, had an anaphylactic response after povidone-iodine solution was applied internally. She was found to be allergic to PVP.[20] In another case, a man experiencing anaphylaxis after taking acetaminophen tablets orally was found to be allergic to PVP.[21]

Povidone is commonly used in conjunction with other chemicals. Some of these, such as iodine, are blamed for allergic responses, although testing results in some patients show no signs of allergy to the suspect chemical. Allergies attributed to these other chemicals may possibly be caused by the PVP instead.[22][23]

Properties

PVP is soluble in water and other polar solvents. For example, it is soluble in various alcohols, such as methanol and ethanol,[24] as well as in more exotic solvents like the deep eutectic solvent formed by choline chloride and urea (Relin).[25] When dry it is a light flaky hygroscopic powder, readily absorbing up to 40% of its weight in atmospheric water. In solution, it has excellent wetting properties and readily forms films. This makes it good as a coating or an additive to coatings.

A 2014 study found fluorescent properties of PVP and its oxidized hydrolyzate.[26]

History

PVP was first synthesized by Walter Reppe and a patent was filed in 1939 for one of the derivatives of acetylene chemistry. PVP was initially used as a blood plasma substitute and later in a wide variety of applications in medicine, pharmacy, cosmetics and industrial production

Vinylpyrrolidone polymer

Polyvinylpyrrolidone is abbreviated as PVP, and is the polymer of vinylpyrrolidone. According to the different degree of polymerization, it is further classified into soluble PVP and insoluble PVPP (polyvinyl polypyrrolidone). Molecular weight of the soluble PVP is 8,000 to 10,000.The soluble PVP can be used as a precipitating agent which can be settle down through its action with polyphenols. Using this method, it is easily to have residual PVP in the alcohol. Due to the savings effect of PVP inside the human body, the World Health Organization doesn't recommend to apply this substance. In recent years, the use of soluble PVP has been rare. Insoluble PVPP system had began to be used in the beer industry since the early 1960s. It has a relative molecule weight greater than the relative mass greater than 700,000. It is a insoluble polymer derived from the further cross-linking and polymerization of PVP and can be used as an adsorbent of polyphenols with a good efficacy.

The molecular formula of Polyvinylpyrrolidone

Polyvinylpyrrolidone PVP is one of the three major pharmaceutical new excipients and can be used as the co-solvent of tablets, granules, and injection, as the glidant of capsules, as the dispersant agent of liquid preparations and the colorant, as the stabilizer of enzyme and heat sensitive drug, as the co-precipitating agent of poorly soluble drugs, and as the detoxicant of ophthalmic drugs and lubricants.

It is industrially used as expanded polystyrene additive, as the gelling agents for suspension polymerization, stabilizer, and fiber treating agents, paper processing aids, adhesives, and thickening agents.

Polyvinylpyrrolidone PVP and its copolymers CAP is an important raw material of cosmetics, mainly used for hair retaining agent. The film it formed in the hair is elastic and shiny, and has excellent carding property as well as being free of dust. Adopting different category of resin can meet various kinds of relative humidity climatic conditions. Therefore, it is an indispensable raw material in styling hair cream, hair gel, and mousse. It can also be used for the cosmetics of skin moisturizing agents and the dispersants for grease based hair dying, also as foam stabilizers, and can improve the consistency of the shampoo.

Insoluble PVP is the stabilizer of beer and juice which can improve its transparency, color, and flavor.

Water-soluble polyamides

Polyvinyl pyrrolidone (PVP) is a water soluble polyamide. Commercially available PVP is divided into four viscosity grades according to its press K value (Fikentscher K value): K-15, K-30, K-60, K-90, with the average molecular weight being 10,000, 40000,160000, and 360000, respectively. K value or molecular weight is an important factor which decides the various properties of PVP.

Polyvinyl pyrrolidone (PVP) is dissolved in water, chlorinated solvents, alcohol, amine, nitro-paraffin and low molecular weight fatty acids, and is mutually soluble with most inorganic salts and a variety of resin; insoluble in acetone and ether. PVP used for the matrix of dropping pill matrix is odorless, tasteless, white to pale yellow waxy solid with the relative density being 1.062, and its 5% aqueous solution pH being 3 to 7. PVP is hygroscopic and of good thermal stability, and can be dissolved in various kinds of organic solvents, and has high melting point. Adding certain natural or synthetic polymers or organic compounds can effectively adjust the PVP's hygroscopicity and softness. PVP is not prone to have chemical reaction. Under normal storage conditions, dry PVP is quite stable. PVP has excellent physical inertia and biocompatibility and has not stimulation to skin, eyes no stimulation with no allergic reactions and being non-toxic.

Because of the hydrogen bonding or complexation effect, PVP's viscosity is increased and this further inhibits the formation and growth of crystallized nuclei of drugs, making the drug being in the amorphous state. The dropping pill whose matrix is PVP can enhance the dissolution and bioavailability of poorly soluble drugs. In general, the greater the PVP amount, the higher dissolution and solubility of drug in the medium. Susana et al have studied the dissolution of the PVP solid dispersant of the slightly soluble drug albendazole. The increased amount of PVP (k30) can increase the dissolution rate and efficiency of drug inside the solid dispersant. Teresa et al have studied the dissolution of the poorly soluble drugs, flunarizine in PVP solid dispersant and obtained similar conclusion. PVP also found that the higher the content, the more significant increase in dissolution. IR has showed that flunarizine and PVP has no chemical reaction except in some cases that a best dissolution efficacy is obtained only in certain ratio between some drugs with the PVP. Tantishaiyakul et al has found that: when the ratio of piroxicam: PVP is 1:5 and 1:6, the dissolution of the solid dispersant is the largest with a 40 times as high as that of single drug within 5min.

PVP can also be dissolved in another molten dropping pill matrix, such as polyethylene glycol (PEG), polyoxyethylene monostearate (S-40), poloxamer and stearyl acid, glyceryl monostearate, etc for making complex matrix.

Physical and chemical properties

Commonly used PVP level in the cosmetic industry is K-30. Commercialized PVP is white and free flowing powder or solids with its content in the mass fraction of 20%, 30%, 45% and 50% aqueous solution. PVP is soluble in water and is hygroscopic with a moisture equilibrium being 1/3 of the relative humidity of the environment. Similar as the protein hydration action, each monomer associates with 0.5mol water.Chart 1 and Chart 2 lists the reference quality standard of various types of polyvinylpyrrolidone PVP:

Food grade and pharmaceutical grade polyvinylpyrrolidone PVP

Chart 1: Food grade and pharmaceutical grade polyvinylpyrrolidone PVP

Cosmetics and industrial polyvinylpyrrolidone PVP (Luvikol K, BASF)

Chart 2: Cosmetics and industrial polyvinylpyrrolidone PVP (Luvikol K, BASF)

PVP is not easy to have chemical reaction. When stored at normal conditions, dry PVP is quite stable. Solution undergone mildew treatment is also stable. When heated in air to 150 °C or mixed with ammonium persulfate to heat at 90 °C for 30min, PVP will be exchanged to become a water-insoluble compound. In the presence of azo compound or a dichromate oxidizing agent, light will cause PVP solution to become gel. The co-heating of PVP solution with strong base (such as sodium silicate or trisodium phosphate) will generate precipitation. Many different compounds can generate complexes with PVP. For example, the complexes of PVP and iodine is very stable and have a good bactericidal effect and can reduce its toxicity; Adding the copolymers of the polyacrylic acid, tannic acid or methyl vinyl ether and maleic acid to the aqueous solution of PVP will generate insoluble complexes which are insoluble in water, alcohols and ketones. But when being treated with base for neutralize the poly-acid can reverse the reaction; complexation between PVP and toxins, drugs and toxic chemicals can reduce their toxicity; some kinds of dyes can also form a strong complex with PVP, which is the basis for using PVP as a dye bleaching agent.

The use of polyvinylpyrrolidone

In the early 1950s, older, with shellac and oil-based hairspray had been rapidly replaced by PVP sprays which are still widely used until now. It can form wet, transparent film on the hair which is shiny and has good lubrication effect. PVP has good compatibility with a variety of good propellant and also has corrosion resistance. It is widely used in hair styling, as the film former in combing products, as the creatinine and stabilizer of skin care lotions and creams, as the base stock material for eye and facial cosmetics and lipstick base, and also as hair dye dispersants and shampoo foam stabilizer. PVP has detoxification effect and can reduce the irritation effects of other preparation on the skin and eyes. It is also used as toothpaste detergents, gelling agents and antidotes. The main drawback of PVP is its sensitivity to moisture. However, this issue can be tackled by using its vinyl acetate copolymer in order to mitigate the effects of moisture and humidity. In addition, PVP also has wide application in the pharmaceutical, beverage and textile industries.

Rheological properties of solutions

Water and methanol is the preferred solvent of PVP. pH value has little effect on the viscosity of the aqueous solution of PVP, for example, at 25 °C, pH range: 0.1~10, aqueous solution of PVP K-30 with a mass fraction of 5% concentration has a viscosity of 2.3~2.4mPa • s; in concentrated hydrochloric acid, this is 4.96mPa • s. Effect of temperature on the viscosity of the PVP aqueous solution is also relatively not obvious. Un-cross-linked PVP solution is not particularly thixotropic unless under very high concentration and display a short relaxation time. The chart 3 below lists the viscosity of PVP K-30 in a variety of solvents.

Compatibility

Polyvinylpyrrolidone is mainly used as pharmaceutical excipient, blood compatibilizer, cosmetics thickening agents, latex stabilizers, and clarifying agent of beer brewing.

Not matter whether in solution or in the form of film, PVP always has a high degree of compatibility. It has good compatibility with various kinds of inorganic salt solution, many natural and synthetic resins and other chemical compatibility. Examples of their compatibility are seen at chart 4 and Figure 5.

Chemical Properties

It is the cross-linked homopolymer of pure vinylpyrrolidone. It is hygroscopic and free-flowing white or off-white powder. It has a slight foul smell. It is insoluble in common solvents such as water, ethanol and ether. So its molecule weight range can't be measured. However, PVP has ability to form complex with various kinds of substances (such as "Hu" class substance which can lead to the discoloration of a variety of wines and beverages discoloration). Also it is easily to be removed after filtration because of its insolubility.

Uses

Clarifying agent; pigment stabilizer; colloidal stabilizer; It is mainly used for beer clarifying and quality stabilizing (reference amount 8~20g/100L, maintained for 24h and remove it by filtration), and can also be applied in combination with enzymes (protease) and protein adsorbents. It is also used to clarify the wine and as a stabilizer to prevent discoloration (reference amount 24~72g/100L).

Clarifying agents; stabilizers; thickeners agent; tablet fillers; dispersants; PVP of molecular weight 360,000 are often used as the clarifying agent of beer, vinegar, and grape wine.

Definition

ChEBI: A vinyl polymer composed of repeating -CH2-CR- units where R is a 2-oxopyrrolidin-1-yl group.

Production Methods

Povidone is manufactured by the Reppe process. Acetylene and formaldehyde are reacted in the presence of a highly active copper acetylide catalyst to form butynediol, which is hydrogenated to butanediol and then cyclodehydrogenated to form butyrolactone. Pyrrolidone is produced by reacting butyrolactone with ammonia. This is followed by a vinylation reaction in which pyrrolidone and acetylene are reacted under pressure. The monomer, vinylpyrrolidone, is then polymerized in the presence of a combination of catalysts to produce povidone.

World Health Organization (WHO)

Polyvidone, a polymer of vinylpyrrolidinone, is an excipient used as a suspending and dispersing agent. Injectable preparations containing polymers with a molecular weight in the order of 12,000 have caused painful local granulomatous lesions. This has led to the withdrawal of polyvidone from such preparations in some countries. Polyvidone was formerly also used as a plasma expander but, because it was sequestered within the liver and spleen, this use has been discontinued. However, it remains widely used as a vehicle for ophthalmic preparations, and as the major component of artificial tears.

General Description

Health Hazard

SYMPTOMS: Polyvinylpyrrolidone may cause interstitial fibrosis in the lungs. Lesions regress when patient is no longer being exposed to the compound.

Fire Hazard

Flash point data for Polyvinylpyrrolidone are not available, but Polyvinylpyrrolidone is probably non-flammable.

Pharmaceutical Applications

Although povidone is used in a variety of pharmaceutical formulations, it is primarily used in solid-dosage forms. In tableting, povidone solutions are used as binders in wet-granulation processes.Povidone is also added to powder blends in the dry form and granulated in situ by the addition of water, alcohol, or hydroalcoholic solutions. Povidone is used as a solubilizer in oral and parenteral formulations, and has been shown to enhance dissolution of poorly soluble drugs from solid-dosage forms. Povidone solutions may also be used as coating agents or as binders when coating active pharmaceutical ingredients on a support such as sugar beads.

Povidone is additionally used as a suspending, stabilizing, or viscosity-increasing agent in a number of topical and oral suspensions and solutions. The solubility of a number of poorly soluble active drugs may be increased by mixing with povidone.

Special grades of pyrogen-free povidone are available and have been used in parenteral formulations;

Contact allergens

Polyvinylpyrrolidone is widely used as is in cosmetics such as hair care products and in medical products. It acts as iodophor in iodine-polyvinylpyrrolidone. PVP is an irritant and has been claimed as the allergen in some cases of dermatitis from iodine-polyvinylpyrrolidone (although iodine is more likely the hapten). It may cause type I contact urticaria or anaphylaxis.

Safety Profile

Mtldly toxic by intraperitoneal and intravenous routes. Questionable carcinogen. When heated to decomposition it emits toxic fumes of NOx.

Safety

Povidone has been used in pharmaceutical formulations for many years, being first used in the 1940s as a plasma expander, although it has now been superseded for this purpose by dextran.

Povidone is widely used as an excipient, particularly in oral tablets and solutions. When consumed orally, povidone may be regarded as essentially nontoxic since it is not absorbed from the gastrointestinal tract or mucous membranes.Povidone additionally has no irritant effect on the skin and causes no sensitization. exists that povidone may accumulate in the organs of the body following intramuscular injection.

A temporary acceptable daily intake for povidone has been set by the WHO at up to 25 mg/kg body-weight.

(mouse, IP): 12 g/kg

storage

Povidone darkens to some extent on heating at 150°C, with a reduction in aqueous solubility. It is stable to a short cycle of heat exposure around 110-130°C; steam sterilization of an aqueous solution does not alter its properties. Aqueous solutions are susceptible to mold growth and consequently require the addition of suitable preservatives.

Povidone may be stored under ordinary conditions without undergoing decomposition or degradation. However, since the powder is hygroscopic, it should be stored in an airtight container in a cool, dry place.

Purification Methods

Purify it by dialysis, and freeze-drying. Also by precipitation from CHCl3 solution by pouring into ether. Dry it in a vacuum over P2O5. For the crosslinked polymer purification is by boiling for 10minutes in 10% HCl and then washing with glass-distilled water until free from Cl ions. Finally, Cl ions are removed more readily by neutralising with KOH and continued washing.

Incompatibilities

Povidone is compatible in solution with a wide range of inorganic salts, natural and synthetic resins, and other chemicals. It forms molecular adducts in solution with sulfathiazole, sodium salicylate, salicylic acid, phenobarbital, tannin, and other compounds; see Section 18. The efficacy of some preservatives, e.g. thimerosal, may be adversely affected by the formation of complexes with povidone.
