Poly(1-vinylpyrrolidone-co-vinyl acetate) is a water-soluble high-molecular polymer copolymerized by N-vinyl-2-pyrrolidone (NVP) and vinyl acetate (VA) in a mass ratio of approximately 60:40.

VA (Copovidone) VA64/VA73 is with CAS number 25086-89-9. PVP VA64 appears as a white to milky white powder, odorless and tasteless, and features low water absorption, strong adhesion and excellent film-forming property.

Its molecular structure combines a hydrophilic pyrrolidone ring with a certain hydrophobic acetate group, thus it has excellent water solubility, film-forming property, adhesion and compatibility, and is widely used in the fields of medicine, daily chemicals, food, etc.

Chemical properties and physical properties ‌

Solubility‌. It is soluble in water, ethanol, isopropanol, dichloromethane and other solvents, and has both hydrophilic and hydrophobic groups, with strong affinity for hydrophobic surfaces.

Structural advantages ‌. It combines the water solubility of PVP and the plasticity of PVAC, has a low glass transition temperature, lower hygroscopicity than PVP K30, and forms a flexible film with low adhesion.

Quality standard ‌. Vinyl acetate content 35.3%-41.4%, nitrogen content 7.0%-8.0%, heavy metal ≤20ppm, in compliance with USP/EP/BP pharmacopoeia standards.

VA64, with its unique physical and chemical properties, is often used in daily chemical products to enhance formula stability, improve user experience or increase efficacy. The specific applications are as follows:

VA64, with its unique physical and chemical properties, is often used in daily chemical products to enhance formula stability, improve user experience or increase efficacy. The specific applications are as follows:

3. Makeup products

Foundation /bb cream: It can enhance the adhesion of powder on the skin surface, making the makeup more smooth and long-lasting, while reducing smudge. It can also improve the product’s spreadability, making the application smoother.

Mascara: As an adhesive and film-forming agent, it helps mascara adhere to the eyelashes, creating a long-lasting curling effect while reducing smudge.

Lip makeup products: In lipsticks and lip glazes, they can enhance the color retention and adhesion of the products, reduce makeup smudging caused by dry lips, and at the same time improve the texture of the products.

4. Other daily chemical products

Body wash/shampoo: Adding a small amount can improve the foam stability and consistency of the product, and enhance the smoothness during use.

Wet wipes: As moisturizers and adhesives, they help the effective ingredients in wet wipes (such as emollients and bactericides) adhere evenly to the skin surface, while enhancing the flexibility of the wet wipes.

In conclusion, VA64 as a high-performance polymer excipient, has become one of the important components in many mainstream products in the daily chemical field by optimizing the user experience, stability and efficacy of the products.
