Polyacrylamide/C13-14 is a synthetic polymer derived from acrylamide and long-chain (C13-14) hydrocarbons. It is commonly used in cosmetic and personal care formulations as a film-former, thickening agent, and stabilizer. This polymer improves product texture, enhances spreadability, and provides a smooth, conditioning feel on skin and hair. It is also valued for its ability to stabilize emulsions and increase viscosity.
