HDI/Trimethylol Hexyllactone Crosspolymer is a synthetic crosslinked polymer used in cosmetics primarily as a slip modifier and soft-focus powder that improves spreadability, mattifies, and gives a smooth, silky skin feel. It typically carries pigments or oils and contributes to the sensory and optical properties of foundations, sunscreens, and color cosmetics.
| Reported effect | How often | Notes |
|---|---|---|
Skin irritation | Rare | Generally considered inert; mild irritation is uncommon and usually formulation-dependent. |
Contact allergy/sensitization | Very rare | Few reports; the crosslinked polymer is largely non-reactive and not significantly absorbed. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
