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.
Our favorite hair conditioner recipe, using BTMS.
Ingredients: Botanical Name: Behentrimonium Methosulfate (and) Cetyl Alcohol (and) Butylene GlycolCommon Name: BTMS-50
This emulsifier works well in lotion. Tonight my temp must have been off because for the first time during the end of the mixing, I noticed the BTMS-50 had gup'd up in a few places at the bottom of the mixer bowl. Concerned, I stop the mixer and scraped the bowl and let the mixer keep turning for another five to seven minutes. To my surprise, the batch wasn't ruined despite having cooled quite a bit since initially pouring. The BTMS-50 just worked its way back into what had blended beautifully.
It feels great on the skin, smooth and powdery.
Looking forward to making hair conditioner next based on everyone's reviews.
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...
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?
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,
Can I mix this with the liquid soap concentrade?
Reply from Bramble Berry Hi Alberto! Your project with Liquid Soap Concentrate Base sounds super interesting! I would love to learn more about it and see if the Btms-50 Conditioning Emulsifier would be the right fit for it. I will email you personally to discuss this further.
