Carbomer 940 is a polyvinyl carboxy polymer used as a viscosity enhancer, gelling agent, or suspension agent. Carbomer 940 is cross linked with ethers of pentaerythritol, and is used primarily in systems where sparkling clarity or a sharp viscosity response is required.

Carbomer 940 polymer is a white powder, crosslinked polyacrylic acid polymer. It is an extremely efficient rheology modifier capable of providing high viscosity and forms sparkling clear gels or hydro-alcoholic gels and creams.
