Characteristics

Excellent film-forming property: It can form a transparent protective film on the skin surface. This film is flexible and breathable, which can effectively lock in moisture and block external pollutants.
Good adhesion: It can enhance the adhesion of other ingredients in the formula and help active ingredients stay better on the skin surface.
Low irritation: Since VP/VA copolymer has high biocompatibility and is mild to the skin, it is very suitable for products for sensitive skin.
Strong stability: The chemical properties are stable, not easily affected by environmental factors, and can maintain performance under different temperature and humidity conditions.

Application

Facial masks and skin creams: Improve product adhesion and long-lasting moisturizing effect.
Sunscreen: Enhance the durability of sunscreen effect, making it less likely to be lost in water or sweat.
Makeup products: Help makeup products such as foundation and eye shadow adhere to the skin better, improve their durability and waterproofness.
Hair care products: Such as hair gel, styling spray, etc., VP/VA copolymers can form a film to help hair maintain its shape.

FAQ

1.Is VP/VA copolymer safe for sensitive skin?

Generally, it has good skin compatibility and low irritation, which is suitable for most skin types, including sensitive skin.

2. Will VP/VA copolymer block pores?

The film formed by VP/VA copolymer has good air permeability and usually does not block pores, which is suitable for daily skin care products.

3. What is the concentration of VP/VA copolymer in skin care products?

Depending on the different formulas and product functions, the concentration is usually between 1% and 10%, depending on the type of product and the target effect.

4. Can VP/VA copolymer improve the moisturizing effect of the skin?

Yes, VP/VA copolymer helps prevent water loss by forming a protective film, thereby enhancing the moisturizing effect of the skin.

5. Can VP/VA copolymer be used in sunscreen products?

It is often used in sunscreen products to help enhance the adhesion and durability of sunscreen agents and prevent the loss of sunscreen ingredients due to sweat or moisture.
