    Best Price, Favorite Emulsifier, Thrilled!

    This is my favorite emulsifier. It acts the same as BTMS 50 I've bought anywhere else. It has never failed on me in any lotion and conditioner, except that one time I tried to use something anionic when I wasn't paying attention. Oils, silicones, electrolytes, it just works.

    BTMS 50

    Posted by Sheila on Jun 18th 2019

    This is the second time I have ordered this product. I use it in lotion, shampoo and conditioner bars. I find it to be a wonderful conditioning agent in all of those products and will order again when I run out. Just a word of warning to first time buyers; when you open the bag and while it is melting, it has a strange fishy smell (which is odd since it is plant based). Don't worry though, it does not remain in the finished product. I only mention it because the first time I used it I thought there was something wrong with it and wished that someone had given me a heads-up. This is an excellent product, buy with confidence.
