Dimer Dilinoleamidopropyl Pg-Dimonium Chloride Phosphate

What is Dimer Dilinoleamidopropyl Pg-Dimonium Chloride Phosphate?

Dimer Dilinoleamidopropyl PG-Dimonium Chloride Phosphate is a synthetic quaternary ammonium compound derived from dimerized linoleic fatty acid, propylene glycol, and a phosphate-linked cationic structure. This lipid-mimicking ingredient falls into the category of mild conditioning surfactants commonly incorporated into hair care formulations such as conditioners, detanglers, and leave-in treatments. It works through electrostatic attraction: its positive charge binds to the negatively charged hair keratin surface, creating a protective, hydrophobic layer. This deposition reduces inter-fiber friction, neutralizes static buildup, and enhances slip for easier combing. The unique dimer fatty chain provides substantivity, ensuring benefits last through multiple shampoos, while the phosphate group contributes to gentleness on skin and scalp during application. Primarily rinse-off, it supports overall hair health appearance without residue buildup.
