What is Behentrimonium Chloride?

Behentrimonium Chloride is a quaternary ammonium salt, primarily used as a conditioning agent in hair care products. It is derived from canola oil or rapeseed oil, and is known for its surfactant properties.

When you see Behentrimonium Chloride on a label, it is often a sign that the product is designed to smooth and condition hair, though checking for personal sensitivities is advised.
