About this ingredient

Carbomer is a synthetic, high molecular weight polymer derived from acrylic acid that functions as a thickening and gelling agent in cosmetic formulations. It absorbs water and swells to form clear, viscous gels that improve product texture, spreadability, and stability while imparting a lightweight, non-greasy feel. Carbomers do not provide active skincare benefits but are essential for creating elegant gel and emulsion textures.
