Sodium Acrylates Crosspolymer-2 Average Absorbent No known benefits Sodium Acrylates Crosspolymer-2 at a glance Synthetic ingredient Used as an absorbent Ruled safe as used in cosmetics Thickener for aqueous formulations Sodium Acrylates Crosspolymer-2 description Sodium acrylates crosspolymer-2 is a synthetic ingredient used as an absorbent in cosmetic formulations. From a chemistry aspect, this polymer is the sodium salt of acrylic acid, methacrylic acid, or an ester of either that is crosslinked with a resin-builder known as ethylene diglycidyl ether. Sodium acrylates crosspolymer-2 can hold up to 20x its weight in water and can provide a soft focus/blurring effect on the skin. Outside of this, it can be used with other polymeric thickeners to enhance/increase viscosity. The independent Cosmetic Ingredient Review has ruled sodium acrylates crosspolymer-2 safe in its current usage in cosmetics, where its concentration levels are generally between 0.47-1.8%.
