Cetrimonium Chloride is a quaternary ammonium salt. In cosmetics and personal care products, it is used in the formulation of hair conditioners, hair dyes and colors, other hair care products, and in some skin care products.
It prevents or inhibits the buildup of static electricity. Cetrimonium Chloride also help to cleanse the skin or to prevent odor by destroying or inhibiting the growth of microorganisms and by helping water to mix with oil and dirt so that they can be rinsed away. It also help to form emulsions by reducing the surface tension of the substances to be emulsified and help to distribute or to suspend an insoluble solid in a liquid.
Cetrimonium chloride carries a positive charge that attracts them to the slightly negatively charged skin and hair proteins, accounting for their use as antistatics.
