Polyquaternium-39

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

It combines film-forming, conditioning, and rheology-modifying functions within a single polymer system, reducing the need for multiple actives in complex chemical formulations.

In hair care, it deposits a conditioning film on the fiber surface during rinsing, improving detangling, softness, and wet combability in shampoos and conditioners for professional use.

Skin care formulators incorporate it into lotions and gels where it contributes moisture retention and a smooth skin feel without leaving a heavy or greasy residue on the surface.

In home care and industrial cleaning products, it modifies solution viscosity and improves surface wetting, supporting more uniform coverage on various hard surfaces and substrates.

It is also used in leave-on hair styling products where controlled film deposition aids hold and manageability, making it a versatile ingredient for modern cosmetic manufacturing.

Polyquaternium-39 is supplied as an aqueous solution, with active polymer content typically ranging from 20% to 40% depending on the specific grade required for the application.

Both cosmetic-grade and technical-grade variants are available to serve personal care and industrial end markets. Buyers should confirm active content, charge density, and viscosity specifications.
