Polyquaternium-51 has super moisturizing properties and its application fields are expected to continue to expand in the future.

Polyquaternium salts are cationic surfactants, which are polymers synthesized by grafting quaternized fatty alkyl groups onto modified natural polymers (saccharides, cellulose, proteins) or cationic monomers containing double bonds. Polyquaternium-51 is a type of polyquaternium salt. It is a copolymer composed of 2-methacryloylhydroxyethylphosphatidylcholine and monomer hydrophobic butyl methacrylate. Its appearance is non-toxic. It is a transparent…
