VA64 CAS 25086-89-9 is a copolymer of vinylpyrrolidone and vinyl acetate. It is a white to milky white powder, easily absorbs moisture, and is soluble in water, ethanol and other organic solvents.

VA64 can be used as a film-forming agent in peel masks, and it also has the functions of improving formula stability and enhancing efficacy. Its core value lies in forming a flexible and easily peelable film, while also assisting the adhesion and penetration of active ingredients.

I. Core Application Functions

1. Film-forming and stripping carriers

This is the primary role of VA64 in peel-off masks. It can quickly form a continuous and uniform film on the skin surface. The film has appropriate strength and flexibility. After drying, it can be completely peeled off without causing skin tightness or discomfort due to excessive contraction.

2. Synergy of active ingredients

VA64 has certain solubilizing and coating capabilities, which can help dissolve or stabilize oil-soluble active ingredients (such as vitamins and plant extracts) in facial masks. During the film-forming process, it can evenly fix these components within the membrane structure. When peeling, it helps clean pore dirt through physical action and simultaneously prolongs the retention time of active ingredients on the skin surface.

3. Improved formula stability

As a high-molecular polymer, VA64 can improve the rheological properties of facial mask liquid, prevent the sedimentation of solid particles (such as abrasive particles and powder active substances) in the formula, and enhance the overall stability and shelf life of the product.

II. Application Advantages

Higher mildness: Compared with traditional film-forming agents, VA64 is less irritating to the skin and is suitable for most skin types.

Strong compatibility: It can be well combined with common ingredients in facial masks such as moisturizers, preservatives, and fragrances, and is less likely to precipitate or stratify.

Excellent film-forming efficiency: It can quickly form a film at room temperature without additional heating, simplifying the production process. Meanwhile, the drying speed is moderate, balancing the user experience and film-forming effect.

III. Conclusion

VA64 is mainly used as a film-forming agent in peel masks, which not only has the functions of synergistic active ingredients and enhancing the stability of the formula, but also features high mildness, strong compatibility and excellent film-forming efficiency.
