Palmitoyl Hydroxypropyltrimonium Amylopectin/Glycerin Crosspolymer
What Palmitoyl Hydroxypropyltrimonium Amylopectin/Glycerin Crosspolymer is & what it does
Trimethylpentanediol/Adipic Acid/Glycerin Crosspolymer is a synthetic film-forming polymer made by crosslinking trimethylpentanediol, adipic acid, and glycerin. In skincare and sunscreen formulas it acts as a film former and texture modifier, helping spread the product evenly and leave a smooth, flexible finish on the skin. A notable property is that it can improve the water resistance and wear of a film, which is useful in long-lasting and sunscreen products.
What does Palmitoyl Hydroxypropyltrimonium Amylopectin/Glycerin Crosspolymer do in skincare?
This ingredient is a starch-based, film-forming polymer used as a conditioning and texturizing agent. Built from amylopectin (a plant starch) modified with palmitoyl and glycerin groups, it forms a light film that can improve skin feel and help condition the surface. It is added to refine texture and give a smooth finish.
Is Palmitoyl Hydroxypropyltrimonium Amylopectin/Glycerin Crosspolymer safe?
This crosspolymer is generally considered safe for use in cosmetics. It is a large, starch-derived polymer that mostly stays on the skin surface as a film. As with any ingredient, people with very sensitive skin may prefer to patch test first.
Is Palmitoyl Hydroxypropyltrimonium Amylopectin/Glycerin Crosspolymer natural or synthetic?
It is partly natural and partly synthetic. The backbone comes from amylopectin, a plant-derived starch, and glycerin, which is often plant-sourced, but these are chemically modified to make the finished polymer. So it is best described as a nature-derived ingredient that has been processed synthetically.
