In Europe, the amount of Behentrimonium chloride allowed in rinse-off and leave-on products shouldn’t exceed a certain percentage (rinse-off hair care products up to 5.0% & leave-on hair products up to 3.0%.).
If you have more than 5 hair masks/conditioners at home take 3 of them and take a look at the labels. Chances are you’ll find Behentrimonium chloride listed among the first ingredients. Behentrimonium chloride is considered toxic in concentrations of 0.1% and higher and is suspected to cause skin and eye irritations
