As a synthetic water-soluble polymer compound, PVP has the general properties of water-soluble polymer compounds, colloidal protection, film-forming properties, adhesiveness, hygroscopicity, solubilization or coacervation, but it has the most unique characteristics and is therefore subject to People pay attention to its excellent solubility and physiological compatibility. In synthetic polymers like PVP, it is both soluble in water and soluble in most organic solvents, with very low toxicity and good physiological compatibility, especially in medicine, food, and cosmetics, which are closely related to people's health. In the field, as the price of its raw material butyrolactone decreases, it will definitely show its good prospects for development.
In the consumption structure of PVP, the cosmetics industry in developed countries accounts for 30% to 50%, and my country accounts for 70% to 80%. Because PVP has extremely low toxicity and physiological inertness, it is non-irritating to the skin and eyes and has a long-term record in the medical field, so it is very safe for cosmetics. In daily cosmetics, PVP and copolymers have good dispersibility and film-forming properties. PVP has a protective colloidal effect in emulsions. It can be used in fatty and non-fatty pastes, as a styling fluid, hairspray and friction Silk styling agent, hair conditioner sunscreen, shampoo foam stabilizer, wave styling agent and dispersant and affinity agent in hair dye. Adding PVP to cream, sunscreen, and depilatory agent can enhance the moisturizing and lubricating effect.
