Dihydroxypropyl PEG 5 Linoleammonium Chloride
What is Dihydroxypropyl PEG 5 Linoleammonium Chloride?
Dihydroxypropyl PEG-5 linoleammonium chloride is a synthetic quaternary ammonium salt derived from linoleic acid, an essential fatty acid from plant sources. It features a long hydrophobic linoleoyl chain linked via a hydrophilic PEG-5 dihydroxypropyl spacer, positively charged with chloride counterion. Primarily incorporated into hair care formulations like conditioners and leave-in treatments, it functions through electrostatic attraction to the negatively charged hair cuticle. This deposition creates a thin conditioning layer that smooths cuticles, reduces inter-fiber friction, and dissipates static charges for better alignment and detangling. Its amphoteric structure aids compatibility in aqueous systems, promoting even distribution during rinsing while leaving residual benefits on hair shafts for enhanced tactile properties without heavy buildup.
