Polyquaternium-39

Polyquaternium-39 (CAS 25136-75-8), also known as AA/DMDAAC/AM copolymer, is a cationic conditioning polymer used in personal care and industrial cleaning formulations.

Where is Polyquaternium-39 used?

• Hair care: conditioning film on the fiber surface during rinsing, improving detangling, softness and wet combability in shampoos and conditioners
• Skin care: moisture retention and smooth skin feel in lotions and gels
• Home care and industrial cleaning: viscosity modification and surface wetting for uniform coverage on hard surfaces
• It combines film-forming, conditioning and rheology-modifying functions in one polymer system.

Commercial specifications

• Active polymer content typically 20% to 40% depending on grade
• Buyers should confirm active content, charge density and viscosity specifications.
