Carbomer, nke a makwaara dị ka Carbomer, bụ polymer kpụrụ site na njikọ kemịkalụ nke acrylic acid ma ọ bụ acrylate na ether allyl group, gụnyere polyacrylic acid (homopolymer) na alkanol acrylate polymer (copolymer) ogologo yinye. Ọdịdị molekụla ya nwere 52 ~ 68% acid dị iche iche, n'ihi ya, o nwere ụfọdụ acidity na hydrophilicity, ma nwee ike igbari na mmiri, ethanol na glycerol.
