C8-22 Alkyl Acrylates/Methacrylic Acid Crosspolymer
What is C8-22 Alkyl Acrylates/Methacrylic Acid Crosspolymer?
C8-22 Alkyl Acrylates/Methacrylic Acid Crosspolymer is a high-molecular-weight synthetic polymer formed by crosslinking C8-22 alkyl acrylates with methacrylic acid. In cosmetic formulations, it acts as a multifunctional rheology modifier, ideal for water-based systems like gels, serums, and lotions. It builds viscosity to create non-dripping, clear textures that spread evenly and suspend active ingredients without settling. This ingredient excels in stabilizing oil-in-water emulsions, preventing separation and enhancing product shelf life. Often used in cleansers, moisturizers, and sunscreens, it delivers a lightweight, silky feel while maintaining transparency and quick absorption on skin. Its structure allows for short-flow properties, making formulations easy to apply without stickiness.
