BTMS-50 is a high-performance conditioning emulsifier and detangler designed for advanced natural haircare and gentle leave-on skincare formulations. Supplied as easy-to-handle pastilles with 50% active Behentrimonium Methosulfate, this ingredient delivers exceptional conditioning, slip, and stability—without the harsh solvents found in traditional quaternary systems.

Derived from colza (rapeseed) oil and supplied in a fatty alcohol and glycol system, BTMS-50 contains no volatile solvents, making it safer, non-hazardous, and more environmentally considerate than IPA-based alternatives. Its unique C22 fatty chain provides superior deposition on hair and skin, resulting in silky softness, improved detangling, and a refined, powdery after-feel.

BTMS-50 is widely regarded as the gold standard emulsifier for conditioners, offering formulators flexibility, mildness, and performance in both rinse-off and leave-on applications.
