Stearamidepropyl dimethylamine

Stearamidepropyl Dimethylamine (CAS 7651-02-7, EC 231-609-1) is a tertiary fatty amide amine supplied under trade names including Adogen S 18V, Tegamine S 13, and Lexamine S 13, as well as the abbreviation SAPDMA. It carries no assigned E-code and belongs to the broader category of fatty acid-derived amines.

In personal care formulations, it functions as a conditioning agent and rheology modifier in rinse-off hair products, where protonation at low pH generates a cationic charge that adsorbs onto negatively charged hair fibres. In textile and leather processing, it acts as a softener and surface-modification agent by reducing inter-fibre friction and improving substrate wettability.

Stearamidepropyl Dimethylamine is subject to REACH registration requirements for supply within the European Economic Area. Buyers should request Safety Data Sheets and confirm compliance documentation prior to procurement. Packaging formats and available grades vary by supplier and should be confirmed at the time of enquiry.
