DI-C12-18 ALKYL DIMONIUM CHLORIDE

Description

DI-C12-18 Alkyl Dimonium Chloride is a quaternary ammonium compound widely used in haircare formulations. This cationic surfactant serves as an effective conditioning agent, imparting softness, manageability, and smoothness to hair strands. Its molecular structure consists of a positively charged nitrogen atom bonded to alkyl chains ranging from 12 to 18 carbon atoms in length.

The ingredient functions by adsorbing onto the negatively charged hair surface, forming a protective film that reduces static electricity and enhances combability. It is particularly beneficial for damaged or chemically treated hair, as it helps to seal the cuticle and reduce moisture loss. DI-C12-18 Alkyl Dimonium Chloride also exhibits antimicrobial properties, contributing to the preservation of haircare products.

In formulations, this compound is typically used at concentrations between 0.5% and 5%, depending on the desired level of conditioning. It is compatible with a wide range of other ingredients, including anionic, nonionic, and amphoteric surfactants. However, formulators should be mindful of potential incompatibilities with certain anionic compounds. The ingredient's effectiveness in leave-in and rinse-off products makes it a versatile choice for various haircare applications.
