Hdi/Trimethylol Hexyllactone Crosspolymer

What is Hdi/Trimethylol Hexyllactone Crosspolymer?

HDI/Trimethylol Hexyllactone Crosspolymer is a lab-synthesized polymer formed by crosslinking hexamethylene diisocyanate with trimethylol hexyllactone, resulting in porous spherical particles. Commonly used in cosmetic powders like foundations and blushes, it belongs to the polyurethane family. In formulations, it absorbs moisture and oils, reducing stickiness and enhancing powder flow. This improves blendability and uniformity, giving products a lightweight, silky feel during application and wear. Its structure minimizes aggregation, ensuring consistent performance in humid conditions or over time.
