Copolymer retinone VA64 (PVP/VA64 copolymer) is a water-soluble polymer copolymer synthesized from ‌ N-vinyl-2-pyrrolidone ‌ and ‌ vinyl acetate ‌ in a ratio of approximately 60:40. It is white to pale yellow free-flowing powder, odorless or with a slight characteristic odor, low hygroscopicity, soluble in water, ethanol and many organic solvents.

It remains stable at high temperatures, suitable for processes such as hot melt extrusion (HME). It can form a transparent, flexible water-soluble film with both hydrophobic and hydrophilic groups, enhancing the elasticity and adhesion of the film. Copolymer VA64 is a commonly used cosmetic ingredient and has multiple applications in the fields of personal care and cosmetics, mainly including the following aspects:

Film-forming agent: Copolymer retinone VA64 can form a uniform, transparent and somewhat flexible film on the surface of the skin or hair. When used on the skin, this film can play a protective role, helping to reduce water loss and prevent the damage of external pollutants to the skin. When used in hair products, it can form a protective film on the surface of the hair strands, which helps repair damaged hair quality, increase the luster and smoothness of the hair, and at the same time, it can also play a certain anti-static role, making the hair easier to comb.

Thickener: It has excellent thickening performance and can increase the viscosity and consistency of cosmetics, making them reach the appropriate usage state. In products such as lotions, creams and gels, copolymer VA64 can adjust the texture of the products, making them easier to apply and evenly distributed on the skin. At the same time, it can also improve the stability of the products and prevent the ingredients from stratifying or settling.

Dispersant: It can help disperse and stabilize various ingredients in cosmetics, especially for some insoluble solid particles or oily components. In products such as foundation, eyeshadow and lipstick, it can evenly disperse pigment and pigment particles in the base, avoiding caking or sedimentation, thereby ensuring the uniformity and stability of the product’s color.

Moisturizer: Copolymer retinone VA64 has certain moisturizing properties, capable of absorbing and retaining moisture in the air, providing moisturizing effects for the skin. It can form a moisturizing barrier on the skin surface, reduce water evaporation, and keep the skin moist and soft. It is especially suitable for care products for dry and sensitive skin.

Adhesive: In some powdered cosmetics such as powder compacts and blush, it functions as an adhesive, firmly bonding powder particles together, giving the product certain formability and stability, making it less likely to break or fall apart. It is also convenient for users to apply the product with a powder puff or brush.
