Carbomer 990 is a crosslinked polyacylate polymer with strong moisturizing ability, acting as high-efficient & low-dosage thickener and suspending agent. It can be neutralized by alkali to form clear gel. Once its carboxyl group is neutralized, molecule chain expands extremely and viscidity comes up, due to mutually exclusion of negative charge. It can enhance yield value and rheology of liquid substances, thus it is easy to get insoluble ingredients(granual, oil drop) suspended at low dosage. It is widely used in O/W lotion and cream as favorable suspending agent.
