Copovidone is a water-soluble polymer used to improve the uptake and drug loading of various pharmaceutical agents, including contraceptive patches.
Poly(1-vinylpyrrolidone-co-vinyl acetate) is the main raw materials of cosmetics are used for hair gel, mousse, shampoo, etc., as well as surfactants, pharmaceuticals and other industrial purposes. They are mainly used as water-soluble adhesives and dry adhesives in granulation and direct tabletting technology, as film-forming materials in film coating, and as pore forming substances in masking agents. It is used for sugar coating to prevent cracking. The chemicalbook bottom coating is used for moisture-proof purposes. Vp/va copolymer series products are mainly used as film-forming agents and styling agents in the field of cosmetics, especially in erupting agents, hair gels, mousse and shampoo series products. They play an important role as film-forming agent and hair styling agent. If they are used together with pvpk30, their use effect will be enhanced.
The appearance is white powder or colorless liquid. The regular type is PVP-64.
