Adipic Acid/Neopentyl Glycol Crosspolymer

What is Adipic Acid/Neopentyl Glycol Crosspolymer?

Adipic Acid/Neopentyl Glycol Crosspolymer is a synthetic polymer derived from adipic acid, a dicarboxylic acid, and neopentyl glycol, a polyol, through a crosslinking process that forms a polyester network. Commonly found in water-based cosmetic formulations like gels, serums, cleansers, and moisturizers, it acts primarily as a rheology modifier. In products, it absorbs water and swells to create a stable, clear gel matrix that improves viscosity without stickiness. This enhances spreadability, suspends other ingredients evenly, and delivers a lightweight, silky skin feel. Its film-forming properties can also provide a subtle protective layer, aiding in product stability and user experience across various skincare categories.
