WHAT IS IT? Behentrimonium chloride is a quaternary ammonium salt used as a preservative, antistatic agent, defrizzer, emulsifier and hair conditioning agent. It is primarily used in hair care products such as conditioner, dye and mousse.

HEALTH RISKS: Behentrimonium chloride is a toxic compound, and concentrations of .1% and higher have been shown to damage the eyes by causing tissue death of the mucous membranes. It’s also highly flammable,  irritating to the skin and can cause an increased risk of cancer, nerve damage, anemia and disintegration of the kidneys.

SAFE ALTERNATIVE: We love Morrocco Method Sea Essence Shampoo —it’s non-toxic and did we mention it really works?
