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.

For lotions?
Has anyone used BTMS-50 in lotion recipes? It sounds like it can emulsification properties as well as being silky. I've been using e-wax for lotions and it seems to make everything feel the same (slightly tacky, even with higher oil combinations). I realize this is off topic...

Love this!
I am thrilled this ingredient was in one of the recipes on Soap Queen. I tried it and I am hooked! It will go in all my lotions! Does anyone know if it has other uses besides lotions?

Hi Susan! I'm so glad you are hooked on our Btms- 50 Conditioning Emulsifier! Btms- 50 is also great to use in scrubs and most commonly in hair conditioner. As seen in the Scrub into Spring: Solid Exfoliating Scrub and Sizzling Summer Hair: Leave-In Argan Oil Conditioner tutorials. I will email you personally to discuss this further.

Very nice
I finally made condioner with BTMS-50 using the recipe you provided (excluding the silk). I absolutely love it and would like to see if I can incorporate it in a shampoo recipe. I also read the review of Alberto and have the same question: can BTMS be used with liquid soap? Do you have information about the pH-level this emulsifier can withstand? With kind regards, Annemieke

Hi Annemieke! I'm so glad you love our BTMS-50 and conditioner it created! Your project with shampoo and liquid soap sounds super interesting as well. I would love to learn more about it and see if the Btms-50 would be the right fit for you. I will email you personally to discuss this further.

Makes the Best Conditioner!
For the past three years I've been using this BTMS 50 in my liquid conditioner that I make me and my sister. It always comes out nice and creamy and is very moisturizing in our hair. since my sister moved away I only make it for myself now and I can say I have no plans to stop anytime soon. So as long as you're selling this BTMS 50 I'll be buying it! :)
