The blend consisting of Behentrimonium methosulfate (&) Cetearyl alcohol (or BTMS) is used as a conditioner and detangler in O-Hair Care's products. BTMS is considered so mild and gentle that it is recommended for use in not only leave-on products but also in products designed specifically for babies and children.

This sophisticated ingredient is also a hair thickener. However, unlike ingredients that add volume to fine or limp hair, BTMS does not cause build-up on the hair. This is in part due to the fact that it does not coat, but actually penetrates the hair shaft.

Do not confuse this ingredient with behentrimonium chloride, which is not nearly as mild or gentle. BTMS is not in any way similar to this ingredient.
