CQpol FD21 (Acrylates/C10-30 Alkyl Acrylate Crosspolymer) is a crosslinked copolymer of acrylic acid and long-chain alkyl acrylate esters. It functions primarily as a high-efficiency rheology modifier, providing thickening, emulsification, and suspension properties in a wide range of pH systems. This polymer provides a smooth, elegant feel to formulations and enhances the stability and texture of emulsions and gels, especially in systems containing surfactants or oils.
