Frequently Asked Questions
What is methyl bis (hydrogenated tallow amidoethyl)-2-hydroxyethyl ammonium methyl sulfate used for?
It is a cationic surfactant (a diamidoamine quaternary ammonium methyl sulfate, CAS 81646-13-1) used industrially as a fabric-softening active in rinse and laundry formulations, and as an antistatic and fiber-conditioning agent for textiles. RawSource supplies it in bulk to formulators of softening and textile-finishing systems.
What is this compound made from?
It is derived from hydrogenated tallow, quaternized to form a diamidoamine quaternary ammonium salt with methyl sulfate as the counterion. Its molecular formula is C26H57NO4S and the CAS number is 81646-13-1.
What type of surfactant is it?
It is a cationic surfactant. The positively charged quaternary ammonium head makes it substantive to negatively charged fiber surfaces, which is the basis of its softening and antistatic performance.
What CAS number and chemical family does this fall under?
CAS 81646-13-1, family Surfactants – Cationic. It is a quaternary ammonium methyl sulfate (quat) of the diamidoamine type.
What bulk packaging and documentation are available?
RawSource ships this cationic quat in drums, totes, and IBCs for manufacturing use, with a Certificate of Analysis (CoA) and Safety Data Sheet (SDS) provided per shipment. Request a bulk quote with your target volume and grade for current pricing and lead time.
