Carbomer

Carbomer is a family of synthetic high molecular weight polymers of acrylic acid, crosslinked with allyl sucrose or allyl pentaerythritol. When neutralised with a base such as sodium hydroxide or triethanolamine, carbomer swells dramatically to form viscous, clear gels with a non-tacky skin feel. It is one of the most widely used thickening and gel-forming agents in cosmetic and pharmaceutical formulations.
