Polyquaternium 55

Polyquaternium-55 (CAS 306769-73-3) is a cationic conditioning polymer used across personal care and industrial textile applications. It deposits onto negatively charged surfaces to deliver substantive conditioning, film formation, and moisture retention.

Formulators select it for its compatibility with anionic surfactant systems and its ability to modify surface feel without buildup. In rinse-off and leave-on hair care, it provides detangling, frizz control, and improved combability at low use levels.

Skin care formulators incorporate it into lotions and serums where it contributes a smooth, non-tacky skin feel alongside humectant performance. In textile processing, it functions as a softening and antistatic finish applied to fabric substrates.

During wet processing, it acts as a surface modifier for various fibers. Paper and leather treatment operations use it to modify surface properties and improve the interaction between substrate and coating layers.

Polyquaternium-55 is typically supplied as an aqueous solution. It is available in personal care-grade quality, with active content and viscosity specifications relevant to cosmetic manufacturing.

Buyers should confirm active polymer concentration and counterion composition when evaluating supplier lots for formulation consistency. This ensures the material meets the necessary performance benchmarks for high-end industrial applications.
