Polyvinylpyrrolidone (PVP) ，cas number 9003-39-8，pvp is a non-ionic polymer that is the most distinctive, best-studied and most widely studied fine chemical among N-vinyl amide polymers. Has developed into non-ionic, cationic, anion 3 categories, industrial grade, pharmaceutical grade, food grade 3 specifications, relative molecular mass from thousands to more than one million homopolymer, copolymer and crosslinked polymer series products, and with its excellent unique properties have been widely used.

The use of PVP is very wide, we are concerned about the safety of product use, the following to give you a detailed talk about several issues that we are more concerned about.

Polyvinylpyrrolidone is a non-ionic polymer compound, mainly used in drugs, food, cosmetics and other items, safety is relatively high, if it is added in accordance with the relevant standards, according to the normal amount of use, after use will not cause discomfort to the human body, there is no harm to the human body. Under normal circumstances, polyvinylpyrrolidone is not harmful to the human body if added in accordance with the relevant addition standards, but if it exceeds the safety standard, it may be harmful.

PVP has excellent physiological inertia, does not participate in human metabolism, has relatively high biocompatibility, and basically has no irritation to human skin, eyes and mucous membranes. Therefore, it can be applied as an adhesive, detoxification agent and co-solvent in the pharmaceutical field. PVP itself has no carcinogenicity, and can form complexes with characteristic polyphenol compounds such as tannins. It can be used as a clarifying agent and stabilizer for beer and juice, and in the field of cosmetics, it can also be used in skin care products such as sunscreen, which can enhance the effect of wetting and lubrication.

Polyvinylpyrrolidone can also be used in lipstick, eyeshadow, mascara and other cosmetic modification, reduce pigment and some components of the skin irritation and toxicity, shaving cream with polyethylpyrrolidone can promote beard softening and lubrication function increase, adding polyethylpyrrolidone in hair color products can adjust the color, improve the durability of the color. Adding polyvinylpyrrolidone to toothpaste formulations can prevent tartar and stone formation.

Is polyvinylpyrrolidone safe for skin?

Because PVP has very low toxicity and high physiological inertia, no irritation to the skin and eyes, it has a wide range of applications in cosmetics. The role of polyvinylpyrrolidone in facial mask: to accelerate the penetration of ingredients, hair retention agent, reduce product irritation, good food safety. Polyethylpyrrolidone has a good affinity for the skin, forms a non-occlusive film on the skin surface, plays the moisturizing role of emollient, after adding polyethylpyrrolidone to the mask, the oil feeling will be reduced, the softness and smoothness will be better, polyethylpyrrolidone can accelerate the penetration of the mask ingredients and extend the residence time of the ingredients.

Is polyvinylpyrrolidone good for hair?

Polyvinylpyrrolidone as a raw material of cosmetics, it is important to use for hair style retention agent, it has many excellent properties, is an indispensable raw material for hair spray, hair cream, mousse, polyethylpyrrolidone has good film forming characteristics, can form a transparent film, has good affinity, easy to dissolve with water, no irritation, no allergy, and has a good protective effect on hair. It is a styling agent and film forming agent for personal care products such as mousse and hair gel. Polyvinylpyrrolidone is attached to the hair to form an invisible film, fixing the hair style, making it durable, keeping bright and non-dusty. When the hair is unkempt, it can be combed and molded again. When not in use, it can be washed with shampoo.

The above is about whether PVP is safe, I hope this article can help you. We are a professional pvp manufacturer with more than 10 years of production experience. If you have any questions, please contact us.
