Tıbbi
PVP, 1950'den sonra travma kurbanları için plazma hacim genişletici olarak kullanıldı. Histamin salınımını provoke etme ve ayrıca kan grubuna müdahale etme kabiliyeti nedeniyle hacim genişletici olarak tercih edilmez.
PVP birçok farmasötik tablette bağlayıcı olarak kullanılır; [2] ağızdan alındığında vücuttan geçer. (Bununla birlikte, otopsiler, krospovidonun (PVPP), oral tüketime yönelik farmasötik tablet enjekte eden madde bağımlılarında pulmoner vasküler yaralanmaya katkıda bulunduğunu bulmuştur. [3] Krospovidon veya povidonun akciğer içinde uzun süreli etkileri bilinmemektedir.)
İyota eklenen PVP, dezenfektan özelliklere sahip olan povidon-iyot adı verilen bir kompleks oluşturur. [4] Bu kompleks çözeltiler, merhem, peserler, sıvı sabunlar ve cerrahi fırçalar gibi çeşitli ürünlerde kullanılır. Diğerlerinin birçoğu arasında Pyodine ve Betadine ticari isimleri altında bilinir.
PVP plörodezde kullanılır (sürekli plevral efüzyonlar nedeniyle plevranın füzyonu). Bu amaçla, povidon iyot talk kadar eşit derecede etkili ve güvenlidir ve kolay bulunabilirlik ve düşük maliyet nedeniyle tercih edilebilir. [5]
PVP bazı kontakt lenslerde ve ambalajlama çözümlerinde kullanılır. Sürtünmeyi azaltır, böylece merceğin içine yerleştirilmiş bir yağlayıcı veya ıslatıcı madde görevi görür. Bu kullanıma örnek olarak Bausch & Lomb'un MoistureSeal Teknolojisine sahip Ultra kontakt lensleri [6] ve Air Optix kontakt lens ambalaj çözeltisi ("kopolimer 845" adı verilen bir bileşen olarak) verilebilir. [7]

N-Vinylpyrrolidone (NVP) is an organic compound consisting of a 5-membered lactam linked to a vinyl group. It is a colorless liquid although commercial samples can appear yellowish.
PVP is produced industrially by vinylation of 2-pyrrolidone, i.e. the base-catalyzed reaction with acetylene.[2] PVP is the precursor to polyvinylpyrrolidone (PVP), an important synthetic material. The PVP monomer is commonly used as a reactive diluent in ultraviolet and electron-beam curable polymers applied as inks, coatings or adhesives.[2]
Polyvinylpyrrolidone (PVP), also commonly called polyvidone or povidone, is a water-soluble polymer made from the monomer N-vinylpyrrolidone.[1]

Medical
PVP was used as a plasma volume expander for trauma victims after the 1950s.It is not preferred as volume expander due to its ability to provoke histamine release and also interfere with blood grouping.
PVP 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.
PVP 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, e.g. Bausch & Lomb's Soothe.[8]
Technical
PVP is used in as an adhesive in glue stick and hot-melt adhesives
PVP is used in as a special additive for batteries, ceramics, fiberglass, inks, and inkjet paper, and in the chemical-mechanical planarization process
PVP is used in as an emulsifier and disintegrant for solution polymerization
PVP is used in increase resolution in photoresists for cathode ray tubes (CRT)[9]
PVP is used in aqueous metal quenching
for production of membranes, such as dialysis and water purification filters
PVP is used in as a binder and complexation agent in agricultural applications such as crop protection, seed treatment and coating
PVP is used in as a thickening agent in tooth whitening gels[10]
PVP is used in 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
PVP is used in as an additive to Doro's RNA extraction buffer[citation needed]
PVP is used in as a liquid-phase dispersion enhancing agent in DOSY NMR [11]
PVP is used in as a surfactant, reducing agent, shape controlling agent and dispersant in nanoparticle synthesis and their self-assembly[12]
PVP is used in 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.[27][28]

General description
Polyvinylpyrrolidone (PVP) can form complexes with phenolics and alkaloids. The complex formation allows removal of phenolics and alkaloids from plant samples, thereby inhibiting any modification of proteins by them and any hindrance they may cause in spectrophotometric determinations of protein content. PVP might also enhances the stability of enzymes.[4]
Application
Polyvinylpyrrolidone PVP has been used in the purification of glutamine synthetases from plant samples.[1] PVP has been used to block the PVDF (polyvinylidene difluoride) membrane and to avoid nonspecific binding.[2][3]

La N-vinylpyrrolidone (NVP) est un composé organique constitué d'un lactame à 5 chaînons lié à un groupe vinyle. Il s'agit d'un liquide incolore, bien que les échantillons commerciaux puissent apparaître jaunâtres.
Le PVP est produit industriellement par vinylation de la 2-pyrrolidone, c'est-à-dire la réaction catalysée par une base avec de l'acétylène. [2] Le PVP est le précurseur de la polyvinylpyrrolidone (PVP), un matériau synthétique important. Le monomère PVP est couramment utilisé comme diluant réactif dans les polymères durcissables aux rayons ultraviolets et aux faisceaux d'électrons appliqués comme encres, revêtements ou adhésifs. [2]
La polyvinylpyrrolidone (PVP), également communément appelée polyvidone ou povidone, est un polymère soluble dans l'eau fabriqué à partir du monomère N-vinylpyrrolidone. [1]
Médical
Le PVP a été utilisé comme expanseur de volume plasmatique pour les victimes de traumatismes après les années 1950. Il n'est pas préféré comme expanseur de volume en raison de sa capacité à provoquer la libération d'histamine et à interférer avec le groupe sanguin.
Le PVP est utilisé comme liant dans de nombreux comprimés pharmaceutiques [2], il traverse simplement le corps lorsqu'il est pris par voie orale. (Cependant, les autopsies ont révélé que la crospovidone (PVPP) contribue aux lésions vasculaires pulmonaires chez les toxicomanes qui ont injecté des comprimés pharmaceutiques destinés à la consommation orale. [3] Les effets à long terme de la crospovidone ou de la povidone dans les poumons sont inconnus.)
Le PVP ajouté à l'iode forme un complexe appelé povidone-iode qui possède des propriétés désinfectantes. [4] Ce complexe est utilisé dans divers produits comme les solutions, les pommades, les pessaires, les savons liquides et les gommages chirurgicaux. Il est connu sous les noms commerciaux Pyodine et Betadine, parmi une pléthore d'autres.
Le PVP est utilisé dans la pleurodèse (fusion de la plèvre en raison d'épanchements pleuraux incessants). À cette fin, la povidone iodée est tout aussi efficace et sûre que le talc, et peut être préférée en raison de sa disponibilité facile et de son faible coût [5].
Le PVP est utilisé dans certaines lentilles de contact et leurs solutions d'emballage. Il réduit la friction, agissant ainsi comme un lubrifiant ou un agent mouillant intégré à la lentille. Des exemples de cette utilisation incluent les lentilles de contact Ultra de Bausch & Lomb avec la technologie MoistureSeal [6] et la solution d'emballage pour lentilles de contact Air Optix (comme ingrédient appelé "copolymère 845"). [7]
Technique
Le PVP est utilisé comme adhésif dans les bâtons de colle et les adhésifs thermofusibles
Le PVP est utilisé comme additif spécial pour les batteries, la céramique, la fibre de verre, les encres et le papier jet d'encre, et dans le processus de planarisation chimico-mécanique
Le PVP est utilisé comme émulsifiant et désintégrant pour la polymérisation en solution
Le PVP est utilisé pour augmenter la résolution dans les résines photosensibles pour tubes à rayons cathodiques (CRT) [9]
Le PVP est utilisé dans la trempe aqueuse des métaux
pour la production de membranes telles que les filtres de dialyse et de purification d'eau
Le PVP est utilisé comme liant et agent de complexation dans des applications agricoles telles que la protection des cultures, le traitement des semences et l'enrobage
Le PVP est utilisé comme agent épaississant dans les gels de blanchiment des dents [10]
Le PVP est utilisé comme une aide pour augmenter la solubilité des médicaments sous des formes posologiques liquides et semi-liquides (sirops, gélules de gélatine molle) et comme inhibiteur de la recristallisation
Le PVP est utilisé comme additif au tampon d'extraction d'ARN de Doro [citation nécessaire]
Le PVP est utilisé comme agent améliorant la dispersion en phase liquide dans la RMN DOSY [11]
Le PVP est utilisé en tant que tensioactif, agent réducteur, agent de contrôle de forme et dispersant dans la synthèse de nanoparticules et leur auto-assemblage [12]
Le PVP est utilisé comme agent stabilisant dans toutes les cellules solaires inorganiques [13]
Autres utilisations
Le PVP se lie exceptionnellement bien aux molécules polaires, en raison de sa polarité. Cela a conduit à son application dans les revêtements pour papiers jet d'encre et transparents de qualité photo, ainsi que dans les encres pour imprimantes à jet d'encre.
Le PVP est également utilisé dans les produits de soins personnels, tels que les shampooings et les dentifrices, dans les peintures et les adhésifs qui doivent être humidifiés, tels que les timbres-poste et les enveloppes à l'ancienne.

Description générale
La polyvinylpyrrolidone (PVP) peut former des complexes avec des composés phénoliques et alcaloïdes. La formation complexe permet l'élimination des composés phénoliques et des alcaloïdes des échantillons de plantes, inhibant ainsi toute modification des protéines par eux et tout obstacle qu'ils peuvent provoquer dans les déterminations spectrophotométriques de la teneur en protéines. Le PVP pourrait également améliorer la stabilité des enzymes. [4]
Application
La polyvinylpyrrolidone PVP a été utilisée dans la purification de glutamine synthétases à partir d'échantillons de plantes. [1] Le PVP a été utilisé pour bloquer la membrane de PVDF (polyvinylidène difluorure) et pour éviter une liaison non spécifique. [2] [3]
