Di-c12-18 alkyl dimonium chloride (inci)

DI-C12-18 alkyl dimonium chloride is chemically a mixture of different, synthetically produced di-esters (DI= acroynm for the twofold ester) of C12-18 aliphatic alcohols (alkanols) and a polyoxyethylene ether of synthetic fatty alcohols (pareth). The C numbering "C n-nx" preceding the ester designation (alkyl fumarate) indicates the number or range of alkyl (carbon) chain lengths. In the di-ester "DI-C12-18 alkyl dimonium chloride", the alkyl chain length consists of 12-18 C atoms. In cosmetic products the di-ester acts as hair tonic and emollient.
