CAS:54182-57-9What Is Carbomer?
Carbomer is a loose white powder, with acidity, hygroscopicity and special slight odor. It can be dissolved in water, ethanol and glycerol. The molecule contains 56% - 58% carboxyl group, so it is weakly acidic. When carbomer is dispersed in water, due to the repulsion between negative charges caused by carboxyl ionization, the crimped polymer stretches out and expands in volume. The pH of 0.5% aqueous dispersion is 2.7 ~ 3.5. 1% aqueous dispersion can be neutralized with alkaline substances to form gel. The concentration of commonly used aqueous dispersion is 0.1% - 3.0%.
