BTMS-50 Conditioning Emulsifier - Behentrimonium Methosulfate or BTMS is a vegetable based conditioning emulsifier. It can be used to emulsify lotions and scrubs but is more commonly used to make hair conditioners. The recommended usage rate is 1 – 15% though we find that much more than 6% in our hair conditioner recipes is overkill. This emulsifying system contains a large percentage of conditioning agents, making it appropriate for leave-on conditioning treatments as well as traditional rinse off hair care. This product contains no hazardous solvents and comes in an easy-to-work-with white pastille.

Behentrimonium Methosulfate is a quaternary ammonium salt derived from the natural plant oil Colza, or what is commonly known as Rapeseed Oil. It is both a mild primary emulsifier and an effective conditioning agent, which provides elegant cationic emulsions for both skin and hair care products. These emulsions leave hair tangle-free and feeling silky smooth and provide skin with a softer, powdery feel after use in skin products such as lotions and creams. BTMS-50 is also capable of emulsifying silicone, adding to its range in hair care products.
