Palmitoyl Hydroxypropyltrimonium Amylopectin/Glycerin Crosspolymer

Palmitoyl Hydroxypropyltrimonium Amylopectin/Glycerin Crosspolymer is a synthetic conditioning agent created by chemically linking palmitoyl groups (fatty acid derivatives) to a crosslinked network of modified starch and glycerin. It is designed to form a lightweight film on the skin surface.This ingredient functions primarily as a skin conditioner, helping to improve the feel and appearance of the skin. It is used in skincare formulations at relatively low concentrations to support texture, smoothness, and hydration.

This crosspolymer works by depositing a thin, invisible film on the skin surface. The starch and glycerin components help bind water to the skin, whilst the palmitoyl groups provide a conditioning, slip-promoting effect.Because it is film-forming rather than penetrating, the ingredient works primarily at the skin's surface rather than within deeper layers. This makes it suitable for formulations where a light, non-occlusive feel is desired.

This ingredient is typically left on the skin as part of a finished product rather than being applied separately. It works well in serums, moisturisers, and primers where a smooth, conditioning base is desired. Layer it under other actives or before sunscreen for best results.

This ingredient is generally well-tolerated and approved for cosmetic use in most regulated markets. It is unlikely to cause irritation, though individuals with starch sensitivity should exercise caution.
