Chem/IUPAC Name:	Trimethyloctadecylammonium chloride
EINECS/ELINCS No:	203-929-1
COSING REF No:	38313

Steartrimonium chloride is a quaternary ammonium salt that is commonly found in hair care products like conditioners and dyes as well as in some skin care products as a preservative, surfactant, and anti-static agent (by having a naturally positive charge that attracts it to the slightly negatively charged skin and hair proteins). It belongs to the class called Alkyl Trimoium Compounds.

Who supplies STEARTRIMONIUM CHLORIDE ?

What is STEARTRIMONIUM CHLORIDE used for?

Steartrimonium chloride works as a preservative, surfactant, anti-static, and hair -conditioning agent in cosmetics and personal care products. By lowering the surface tension of the ingredients to be emulsified and aiding in the distribution or suspension of an insoluble solid in a liquid, it also aids in the formation of emulsions.

Hair care: It works as an anti-static agent and a hair-conditioning agent. It prevents or inhibits the build-up of static electricity in your hair Its use as an antistatic agent is due to the positive charge it carries, which draws it to the slightly negatively charged skin and hair proteins. It is used in the formulation of hair conditioners, hair dyes and colours, other hair care products, and in some skin care products

Origin

Trimoniums are typically created by reacting a tertiary amine, such as a nitrogen atom with two methyl groups and one alkyl group attached to it, with a traditional alkylating agent, such as methyl halide or dimethyl sulphate.

Safety profile

The Cosmetic Ingredient Review (CIR) Expert Panel has reviewed the safety of steartrimonium chloride and came to the conclusion that all three ingredients were safe for use in rinse-off products and were also safe to use in leave-on products at concentrations up to 0.25%. 2.5% Steartrimonium Chloride dermal exposure did not show any evidence of developmental effects. The results of each and every mutagenesis assay used were negative. The maximum concentration of these ingredients as preservatives is 0.1%.
