Poly(methyl vinyl ether-alt-maleic anhydride) CAS 9011-16-9

PMVEMA Applications and Uses

1. Hair Styling Products

PMVEMA is widely used as the primary film-forming agent in hair styling products such as gels, mousses, and hair sprays. It forms a flexible, durable film over the hair surface, providing strong hold, long-lasting style retention, and resistance to humidity. In addition, it imparts a smooth, non-sticky texture that enhances combability, making it ideal for professional and consumer hair-care formulations.

2. Skin Care and Cosmetic Products

In skincare, PMVEMA acts as a film-forming agent and thickener in products such as facial masks, lotions, and creams. It creates a breathable, protective film on the skin surface that locks in moisture and active ingredients, enhancing hydration and product efficacy. Its excellent compatibility with other cosmetic ingredients makes it a versatile polymer for anti-aging, brightening, and nutrient-enriched formulations.

3. Toothpaste and Oral Care

PMVEMA serves as a binder in toothpaste formulations, effectively combining solid powder ingredients like abrasives, fluoride, and flavor agents to form a uniform, smooth paste. This improves the stability, texture, and flow properties of toothpaste while ensuring consistent performance and easy dispensing during use.

4. Shaving Cream and Personal Care

In shaving creams and gels, PMVEMA functions as a lubricant and thickening agent, providing smooth glide, enhanced skin protection, and stable foam formation. It improves product feel and application performance, while maintaining a consistent texture during storage and use, making it a preferred polymer in high-quality personal care products.

5. Other Cosmetic and Pharmaceutical Applications

Beyond the above, PMVEMA is also used in controlled-release systems, emulsions, and specialty gels. Its film-forming, adhesive, and dispersing properties allow for innovative formulations in topical medications, face masks, serums, and nutrient-delivery cosmetics, where enhanced stability and controlled release of actives are required.
