Behentrimonium Chloride

Mid risk

FunctionConditioning Quat

What it is — Behentrimonium Chloride (INCI: Behentrimonium Chloride) is a cationic (positively charged) quaternary ammonium conditioning agent.

What it does — It is commonly used to smooth hair, reduce static and help detangle, and it can also act as a mild emulsifier.

Typical use — It appears mainly in rinse-off and leave-in conditioners, masks and detangling sprays, usually at low levels.

Who it suits / good to know — Valued in hair care for slip and softness. As a conditioning quat it can feel too rich for very fine hair, and at higher levels these ingredients are more likely to irritate, so formulas keep them low.

Safety — DHALIORA grades it mid risk in its EWG-style, ingredient-by-ingredient review. This reflects the ingredient in general and is not medical advice; patch-test before wider use if your skin is reactive.

How grades are set — Risk reflects our own reading of publicly available safety data, an EWG-style reading shown at the worst-case grade we've assigned this ingredient across products. It isn't a third party's proprietary score, and it isn't medical advice. Always read the packaging and patch-test where indicated.
