All natural BTMS 25 is derived from Colza oil, and is a blend of 25% behentrimonium methosulfate in cetearyl alcohol. The active compound is comprised of a positively charged quaternary ammonium salt coupled with a fatty carbon chain. The cationic part deposits towards negatively charged surfaces such as hair, while the long carbon chain imparts a smooth and conditioned after feel. The second component, cetearyl alcohol, is a nonionic surfactant used to support the development of the lamellar structure of the formulation. Its inverted conical shape helps with the packing parameter of the quaternary ammonium compound, improving the viscosity of the formula and the spreadability of the conditioner. In addition, cetearyl alcohol imparts additional lubricity to the hair, making it a smart conditioning ingredient.

Compatibility In conditioning systems, BTMS 25 CA can be used in combination with other cationic surfactants to allow for fine tuning of conditioning properties, after feel as well as wet and dry combing.

In shampoo systems, BTMS 25 CA is also compatible with non ionic surfactants. In anionic surfactants, it can react to form electroneutral salts only poorly soluble in water. To avoid this reaction, an excess of the anionic compound should be used. pH stability

It can also be used as a co-emulsifier with Emulsifying Wax NF, adding its conditioning properties to emulsions

The typical use concentration can be between 1.0 to 5.0% depending on hair type and grade of hair damage

As a quaternary ammonium salt our BTMS 25 CA has excellent stability over a wide pH range. It differs from tertiary amines in that the cation persists also in alkaline medium.
