In the consumption structure of PVP, the cosmetics industry in developed countries accounts for 30% to 50%, while China accounts for 70% to 80%. Due to its extremely low toxicity and physiological inertness, PVP is non irritating to the skin and eyes, and has a record of long-term use in the pharmaceutical field, making it very safe for use in cosmetics and other products. In daily cosmetics, PVP and copolymer have good dispersibility and film-forming property. PVP can protect colloid in lotion, and can be used in fat and non fat creams, as setting liquid, hair spray and mousse setting agent, hair conditioner sunscreen, shampoo foam stabilizer, wave setting agent, and hair dye dispersant and affinity agent. Adding PVP to snow cream, sunscreen, and hair removal agents can enhance wetting and lubrication effects.
