Chemical compound

Cetrimonium chloride, or cetyltrimethylammonium chloride (CTAC), is a topical antiseptic and surfactant. Long-chain quaternary ammonium surfactants, such as cetyltrimethylammonium chloride (CTAC), are generally combined with long-chain fatty alcohols, such as stearyl alcohols, in formulations of hair conditioners and shampoos.[1][2] The cationic surfactant concentration in conditioners is generally of the order of 1–2% and the alcohol concentrations are usually equal to or greater than those of the cationic surfactants. The ternary system, surfactant/fatty alcohol/water, leads to a lamellar structure forming a percolated network giving rise to a gel. [2]
