Polyvinylpyrrolidone  is one of the important excipients advocated internationally. PVP is a white to milky white powder. Easily soluble in water, alcohol, amines and halogenated hydrocarbons, but insoluble in acetone, ether, etc. It has excellent solubility, biocompatibility, physiological inertness, film-forming properties, film protection ability and the ability to combine various organic and inorganic compounds, and is relatively stable to acids, salts and heat. Therefore it has a wide range of uses.

As a multifunctional synthetic polymer, Polyvinylpyrrolidone (PVP) has become an important component in cosmetics and personal care products due to its unique physical and chemical properties. PVP  is widely used in various products because of its good water solubility, film forming and biocompatibility. Polyvinylpyrrolidone (PVP) is a non-ionic water-soluble polymer with hydrophilic groups in its molecular structure, so it has good solubility. PVP has a wide range of molecular weights, from low to high molecular weight, which allows it to perform different functions in different applications.

‌The application of polyvinylpyrrolidone PVP in hair gel is mainly reflected in its excellent film formation and moisturizing and repairing function. Polyethylpyrrolidone is a non-ionic polymer with excellent solubility, solubilization, film forming, complexation, bonding and surface activity. In hairspray, PVP can form a transparent film, with good affinity and protective effect, can fix the hairstyle and keep it bright for a long time, not easy to dust ‌12. In addition, PVP can penetrate into the inside of the hair, provide sufficient moisture for the hair, form a protective film, repair damaged hair, improve dry hair, brittle hair and other problems.

The specific action mechanisms of PVP in hair gel include:
‌Moisturizing repair: PVP can penetrate into the inside of the hair, provide sufficient moisture for the hair, and form a protective film, repair damaged hair, improve dry, brittle hair ‌.
‌Antioxidant: PVP has strong antioxidant function, can prevent hair oxidation due to external environmental factors, improve hair frizz, easy knotting and other problems ‌.
‌Stereotyping effect: PVP has certain stereotyping effect, which can improve hair style and make hair more supple and shiny‌.

Polyvinylpyrrolidone  is widely considered safe for use in cosmetics and personal care products due to its good biocompatibility and low toxicity. Multiple studies have shown that PVP does not cause skin allergies or irritating reactions at recommended concentrations, and its molecular structure makes it difficult to absorb through the skin, further reducing potential systemic toxicity.
