What is BTMS 25?

BTMS 25, in full Behentrimonium Methosulfate, is a conditioning emulsifier often used in hair and skin care products. It is valued for its ability to condition and soften, making it a popular ingredient in DIY cosmetics. Unlike sulfates, which are often associated with dehydration, Behentrimonium Methosulfate has mild cleansing properties and offers moisturizing benefits.

Benefits of BTMS 25 in cosmetics

  1. Conditioning properties: BTMS 25 is known for its excellent conditioning properties. It helps detangle hair and makes it smooth and soft, making it easier to comb. Moreover, it contributes to the overall softness and manageability of the hair.

  2. Emulsifying power: As an emulsifier, BTMS 25 plays a crucial role in mixing water and oil in cosmetic formulations. It helps create stable emulsions, such as lotions and creams, allowing ingredients to be evenly distributed and easily applied.

  3. Moisturizing properties: In addition to its conditioning and emulsifying properties, BTMS 25 also has moisturizing properties. It helps maintain the natural moisture balance of the skin and hair, keeping them hydrated and supple.

  4. Anti-static action: BTMS 25 also helps reduce static electricity in the hair, keeping it smooth and frizz-free. This makes it a valuable ingredient in hair care products, especially for people with frizzy hair.

How to use BTMS 25 in DIY cosmetics

Using BTMS 25 in DIY cosmetics requires accuracy and knowledge of proper procedures. Here are some steps to use BTMS 25 effectively:

  1. Choosing the right percentage: The recommended percentage of BTMS 25 in cosmetic formulations usually varies between 1% and 10%, depending on the desired effect and the type of formulation. It is important to use the right amount to achieve optimal results without disturbing the texture of the product.

  2. Adding to the oil phase: BTMS 25 is a lipophilic emulsifier, which means it is best added to the oil phase of cosmetic formulations. Adding it to the oil components before water is introduced allows the emulsion process to run smoothly.

  3. Stepwise heating and mixing: To effectively activate and emulsify BTMS 25, it is important to heat the oil phase slowly until the emulsifier is completely melted and evenly distributed. This ensures a stable and homogeneous emulsion.

  4. Compatibility with other ingredients: Although BTMS 25 is generally well compatible with many other ingredients, it is important to exercise caution when combining it with certain oils or actives that may not mix well. Running small test batches can help identify compatibility issues before larger quantities are produced.
