Ethoxylated stearylamine

Ethoxylated Stearylamine (CAS 26635-92-7, EC 607-973-6) is a fatty amine ethoxylate derived from stearylamine reacted with ethylene oxide. It is sold under trade names including Rokamin S, Teric 18M, RY 130T2, and TB 12. It carries no assigned E-code and is classified within the nonionic and cationic surfactant category.

In textile processing, it functions as a softening and antistatic agent by orienting its cationic amine group toward fiber surfaces, reducing friction and static charge buildup. In agricultural formulations, it acts as an emulsifier and adjuvant, improving the dispersion and leaf adhesion of active ingredients. It also serves as a degreasing component in industrial cleaning systems through its dual hydrophilic-lipophilic structure.

Ethoxylated Stearylamine is supplied in varying ethoxylation grades, which determine HLB value and application suitability. It is subject to REACH registration requirements within the EU. Procurement teams should confirm grade specification, ethylene oxide mole count, and packaging format directly with the supplier.
