What is Polyacrylamide?
Polyacrylamide is a polymer formed from acrylamide monomers. It occurs in two forms, namely straight-chained polymer and branched-chain polymer. It is a synthetically produced compound available as a white solid (beads or powder), an aqueous solution, or as an emulsion. It is a non-ionic, water-soluble biocompatible polymer used in a wide range of cosmetic products.
Use & Benefits:
Polyacrylamide functions as a thickener or suspending agent in cosmetic products. On drying, it forms a thin coating on skin, hair, or nails. In a product, it helps the ingredients to bind together in its compressed tablet or cake form. When in any formulation a solid has to mix with liquid, polyacrylamide makes it easier to suspend solid particles evenly. It is especially important in case of suspensions like nail polish, lip gloss to name a few. It also helps in keeping the cosmetic product on the skin even after coming in contact with water, like sunscreens, so it produces a water-resistant and protective film on the surface. This protective film is an added advantage in case of any formulation. In hair care products, it forms a thin coating on hair and helps it to retain its styling for a longer period by reducing the absorption of water. It is used in formulations of skin cleansers, moisturizers, sun care, hair care, and skincare products.
