BTMS, also known as Conditioning Emulsifier is a self-emulsifying wax, a quaternary ammonium salt derived from the natural plant oil Colza, and contains no ethoxylated ingredients. It is equivalent to BTMS-25. It is both a mild primary emulsifier and an excellent conditioning agent, which provides elegant cationic emulsions for both skin and hair care products. These creams tend to resist wash off, leaving a soft, powdery feel on the skin and imparting excellent detangling properties to hair conditioners.
In a hair conditioner, it offers improved wet comb and leaves hair with noticeable body and spring. Due to its extreme mildness, it is suitable for leave-in conditioners. BTMS can emulsify many silicones (up to 50% in a formulation) and is an excellent suspending agent. BTMS can be used as a co-emulsifier with Emulsifying Wax NF, adding its conditioning properties to emulsions.
