Carbomer 990 is a cross-linked polyacrylate polymer, polymerized in co-solvent of ethyl acetate and cyclohexane. It is used as a high-efficient rheology modifier, capable of providing high viscosity, excellent thickening and suspending performance with low-dosage. It is also widely used in O/W lotions and creams as a favorable suspending agent. When neutralized by alkali it forms sparkling clear water or hydroalcoholic gels and creams.
