Behentrimonium Methosulfate CAS 81646-13-1

Behentrimonium Methosulfate is supplied as a cationic quaternary ammonium compound used in conditioning formulations, primarily in hair care systems where detangling, softening, and antistatic performance are required. In commercial practice, it is commonly provided as a formulated raw material blended with fatty alcohols (such as cetearyl alcohol) to improve handling, stability, and formulation compatibility.

This product is widely used in conditioners, hair masks, and cream-based systems, where it functions as a conditioning emulsifier and deposition aid. It is available in flake or pellet form, suitable for hot-process emulsification. Standard packaging, batch documentation (COA, TDS, SDS), and supply support are available for both formulation development and bulk production.
