Polyvinylpyrrolidone toxicity

Polyvinylpyrrolidone (PVP), also commonly called polyvidone or povidone, is a water-soluble polymer made from the monomer N-vinylpyrrolidone. Uses 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.. Toxicity Profile for Polyvinylpyrrolidone (1991) Polyvinylpyrrolidone did not irritate or induce sensitization when applied to the skin of volunteers, and was not irritant to the eyes of rabbits Au Centre international de recherche sur le cancer, la polyvinylpyrrolidone est « inclassable quant à sa cancérogénicité pour l'homme », tandis que l'Association pour la recherche thérapeutique anticancéreuse (ARTAC, France) la classe parmi les additifs certainement cancérigènes

Polyvinylpyrrolidone (PVP) is a versatile ingredient used in the cosmetics and beauty industry as a binder, film former, emulsion stabilizer, suspending agent and hair fixative, and is seen primarily in products such as mascara, eyeliner, hair conditioners, hair sprays, shampoos and other hair care products, according to the Cosmetics Database and CosmeticsInfo.org Hence, their toxicity potential needs to be comprehensively evaluated. It was postulated that within small-sized (≤20 nm) polyvinylpyrrolidone-coated silver nanoparticles (PVP-AgNP), minor size differences may significantly induce different toxicity profiles and involve varying cellular pathways Polyvinylpyrrolidone - K17 SECTION 12: Ecological information Ecotoxicity Not regarded as dangerous for the environment. However, large or frequent spills may have hazardous effects on the environment. 12.1. Toxicity Toxicity Based on available data the classification criteria are not met. 12.2.

Here we evaluate the use of Polyvinylpyrrolidone (PVP) water solutions as potential isotropic phantoms for diffusion MRI studies. We found almost no previous data on diffusion measurements of PVP solutions (2). A large body of literature is available about the toxicology of PVP and this compound is considered.

Polyvinylpyrrolidone, also named Povidone or PVP, is a nonionic amphiphilic polymer. Because of its exceptional combination of properties like low toxicity, biocompatibility, film forming and adhesive characteristics, complexing ability to proton donors, and low osmotic pressure, it. The composition of the dressings is based on polyvinylpyrrolidone (PVP), polyethylene glycol (PEG), and agar. The electron beam irradiation technique has been used to prepare hydrogel wound dressings.

More than 75 years of tradition in PVP production. PVP is a product that has been a real success story. More than 75 years ago, at the beginning of 1939, the chemist Walter Reppe, working in a BASF laboratory in Ludwigshafen, patented the production process for the polymer Polyvinyl pyrrolidone.

These very large polymers exhibit little toxicity. In rabbits and guinea pigs, Acrylates Copolymer did produce irritation, but no evidence of sensitization was found. The principle concern regarding the use of these polymer ingredients is the presence of toxic residual monomers. In particular, although 2-ethylhexyl acrylate was not genotoxic, it was carcinogenic when applied at a concentration. Polyvinylpyrrolidone (PVP), Polyvidone, is a water-soluble polymer made from the monomer N-vinylpyrrolidone. PVP is soluble in water and other polar solvents. PVP is a component of nucleic acid (DNA & RNA) extraction buffers. Polyvinylpyrrolidone is a component of Denhardt′s Solution and is included at a concentration of 1% (w/v) in the standard 50X stock solution Developmental toxicity was also investigated: the inhalation study in rats showed no adverse effects at the highest concentration, 300 ppm (1.08 mg/l), other than reduced maternal and fetal weight. The rabbit inhalation study showed a small increase in cardiac malformations at 570 ppm (2.052mg/L), in absence of maternal toxicity signs. The oral studies (rat and rabbit) indicate that high doses.

The influence of polyvinylpyrrolidone (PVP) on the toxicity of cryoprotective agents in different liver cell types and on vitrification outcome in precision-cut liver and kidney slices By Na Guan, Sylvia Blomsma, Marina de Jager, Gregory M. Fahy, Genoveva Groothuis and Inge de Graa Contributions of coatings to the toxicity of NPs have received little attention. Studies using AgNPs with one of three different coating materials (citrate (Cit), gum arabic (GA), and polyvinylpyrrolidone (PVP)) showed significantly different toxicity. GA AgNP proved to be the most toxic, while PVP and Cit AgNP exhibited similar and lower toxicity. However, all AgNPs were about three to ten.

Luvitec® K 90 powder can also be used as protective colloid and thickening agent in adhesive dispersions We use density functional theory to resolve the role of polyvinylpyrrolidone (PVP) in the shape-selective synthesis of Ag nanostructures. At the segment level, PVP binds more strongly to Ag(100) than Ag(111) because of a surface-sensitive balance between direct binding and van der Waals attraction. At the chain level, correlated segment binding leads to a strong preference for PVP bind to Ag. Aquatic Toxicity: Juvenile Turbot: 96-hr.
