Function of Behentrimonium Methosulfate (BTMS 90%) as an Emulsifier

Yes, Behentrimonium methosulfate (BTMS 90%) functions as both a powerful conditioning agent and a cationic emulsifier.

Here are the details regarding its role as an emulsifier:

• Cationic Emulsifier: Unlike traditional non-ionic or anionic emulsifiers, BTMS is cationic (positively charged). This allows it to emulsify oil and water while simultaneously providing "substantivity," meaning it binds to the negatively charged surfaces of hair and skin to provide lasting softness.
• Oil-in-Water (O/W) Emulsions: It is used to create stable oil-in-water emulsions. It is particularly valued in hair conditioners and leave-in treatments because it provides an exceptionally silky feel and excellent detangling properties.
• Skin Care Benefits: In lotions and creams, it acts as an emulsifier that leaves a unique "powdery" and non-greasy finish on the skin, which is often preferred over the heavier feel of traditional emulsifying waxes.
• Usage Note: While Behentrimonium methosulfate (BTMS 90%) has emulsifying capabilities, it is often used in combination with fatty alcohols (such as Cetyl Alcohol or Cetearyl Alcohol) to increase the viscosity and stability of the final emulsion.

If you are looking for a version that is already blended with fatty alcohols for easier use in creating thick creams, you might also consider Behentrimonium methosulfate (BTMS 50%).
