Palmitamidopropyltrimonium chloride

Palmitamidopropyltrimonium chloride (CAS 51277-96-4, EC 257-104-6) is a quaternary ammonium surfactant derived from palmitic acid, commonly supplied under the trade name Varisoft PATC. It carries a permanent positive charge, classifying it as a cationic conditioning agent within the broader surfactant category.

In personal care formulations, it adsorbs onto negatively charged hair and skin surfaces, reducing static and improving wet combability in conditioners and rinse-off treatments. In textile processing, it functions as a softening agent by orienting its hydrophobic tail toward fiber surfaces, modifying hand feel and reducing friction during finishing operations.

Palmitamidopropyltrimonium chloride is subject to REACH registration requirements for EU-based suppliers and importers. It is handled as a specialty cationic surfactant without an assigned E-code. Procurement teams should confirm available concentration grades and packaging formats directly with the supplier, as these vary by manufacturer.
