BTMS description

BTMS (divided into BTMS-25 or BTMS-50, where the number indicates the amount of active ingredient blended with fatty alcohols) is one of the most popular ingredients for hair care. It is a cationic (positively charged) emulsifier. Since damaged hair is negatively charged, BTMS is magnetically attracted to the worn parts of the hair strand. There it forms an ultra-thin, silky film that seals the hair cuticle, removes static electricity, and provides fantastic shine and softness. Despite the word "Methosulfate" in the name, BTMS is absolutely not a drying sulfate, but an extremely mild ingredient known for not irritating skin or scalp. It is indispensable in solid shampoos, hair conditioners, and hair masks because it makes it easy to blend oil and water into creamy products. When used in skincare products like lotions, it provides a unique, luxurious feel that absorbs quickly without feeling greasy or sticky.
