BTMS Behentrimonium methosulfate

BTMS - behentrimonium methosulfate -

is a cationic quaternary ammonium salt derived from the Behenyl fatty acid that is prevalent in rapeseed oil (the plant for canola oil /colza Oil). As carbon chain lengths have a direct bearing on the efficacy of the conditioner we can generalise that the longer carbon chain (C₂₂), - the better the de-tangling properties on the hair and lubrication of the skin. It also relates to the reduction in the electrostatic charge, which reduces the chances of flyaway hair.  

BTMS offers “variable” conditioning, allowing formulators to customise their product’s conditioning effects for skin and hair. BTMS forms stable cationic emulsions, allowing formulators to produce creams and lotions that have a soft, powdery after-feel, yet it is safe and gentle enough for skin care. BTMS is also a highly effective hair detangler due to the long behenyl (C₂₂) chain and is preferred by panellists in salon evaluations over industry benchmarks.

BMTS will improve hair's texture and controls static, but on its own it can be difficult to process. Adding a fatty alcohol like cetyl alcohol or cetearyl alcohol will help with making it easier to process and at same time help with lubricity and thus reduce the combing forces for wet and dry hair and reduces the friction between strands of hair. 

BTMS is an excellent suspending agent, providing  sufficient viscosity, making the use of auxiliary thickeners unnecessary in your formulations. A unique property of BTMS is its ability to emulsify high levels (up to 50%) of silicone. BTMS contains 26% active conditioning agents.
