Sodium Acrylates Copolymer is a water-soluble polymer that acts as a film-forming agent, emulsion stabilizer, and viscosity controller.(1) Polymers are small molecules consisting of repeating units of chemically bonded monomers. They are ubiquitous in nature; for example, the DNA of all living cells, as well as the proteins and starch in our food, are all composed of polymers. The polymers most commonly used in cosmetics have cationic charges, which give the skin a smooth and nourishing effect. Other polymers can, for example, form a film on the skin’s surface.(2)
