Carbomer 940
What is Carbomer 940?
Carbomer 940 is a high-molecular-weight, cross-linked polyacrylic acid polymer, a type of synthetic carbomer developed for cosmetic applications. It functions primarily as a rheology control agent, thickening liquids into clear gels when hydrated and neutralized with bases such as sodium hydroxide or triethanolamine. This swelling action forms viscous networks that suspend ingredients and improve spreadability. Commonly found in water-based formulations like gels, lotions, serums, cleansers, and sunscreens, it enhances product stability, prevents ingredient separation, and delivers a non-dripping, silky feel without greasiness. Its inert nature ensures it remains on the skin's surface, supporting consistent performance across pH ranges.
Benefits
