Application of poly vinyl pyrrolidone in cosmetics

2020-03-31
In addition to being used in hair cosmetics, poly vinyl pyrrolidone can also be used in skin care moisturizers, cream-based hair dye dispersants, and foam stabilizers in cosmetics. Because of its good moisturizing properties, it is widely used in the manufacture of skin care agents, cleansing agents, shampoos, toothpaste, etc.

The skin care agent made of Polyvinylpyrrolidone can kill the virus and prevent wrinkles. It can effectively extend the penetration and retention time in cosmetics, which can be used for skin moisturizing and skin care. PVP is used in lipsticks, eye shadows, and mascara to reduce skin irritation caused by pigments and certain ingredients. PVP used in soaps can improve the sticking strength of bar soap. In sanitary soaps, Polyvinylpyrrolidone (PVP) can form complexes with fungicides to reduce skin irritation. PVP is used in liquid detergents to prevent cross-coloring and anti-redeposition, and to prevent skin irritation caused by synthetic detergents. For example, a liquid detergent formulation is: sodium alkylbenzene sulfonate 10.0% (mass fraction, the same below); surfactant 5.6; PVP 0.7%; sodium tripolyphosphate 12.0; Potassium silicate 4. O%; potassium xylene sulfonate 5. O%; water 62.7%. In addition, PvP used in enzyme-based laundry detergents, as both an adjuvant and a binding agent and stabilizer, can prevent the enzyme from being damaged by moisture and sodium percarbonate.
