Description

Glyceryl Polymethacrylate is a high-performance, multifunctional polymer widely used as a film-forming agent, thickener, and stabilizer. Its unique structure provides excellent moisture retention, skin adhesion, and compatibility with a wide range of cosmetic and pharmaceutical ingredients. This makes it a critical component for formulators seeking to enhance product texture, stability, and sensory profile. Key industries that rely on this ingredient include personal care, cosmetics, topical pharmaceuticals, and advanced material science.

Application

• Cosmetic & Personal Care Formulations: Primarily used as a film-forming agent in sunscreens, moisturizers, and color cosmetics to improve water resistance and skin feel.
• Topical Pharmaceutical Gels & Creams: Acts as a stabilizer and viscosity modifier in dermatological preparations, enhancing drug delivery and product shelf life.
• Hair Styling Products: Provides strong hold, curl retention, and humidity resistance in gels, mousses, and sprays.
• Skin Care Serums & Lotions: Functions as an effective thickener and emulsifier, creating smooth, non-greasy textures with superior spreadability.
• Make-up & Foundations: Improves the long-wear properties, waterproofing, and even application of cosmetic products.
• Medical Adhesives & Patches: Utilized for its bioadhesive properties in transdermal drug delivery systems and wound care dressings.
• Industrial Coatings: Serves as a component in specialty coatings requiring flexibility, adhesion, and water resistance.
