Hdi/Trimethylol Hexyllactone Crosspolymer

What Hdi/Trimethylol Hexyllactone Crosspolymer is & what it does

A soft, spherical powder that gives a silky slip and soft-focus blur while absorbing oil. It refines texture and mattifies.

What is Hdi/Trimethylol Hexyllactone Crosspolymer and what does it do in sunscreen?

Hdi/Trimethylol Hexyllactone Crosspolymer is a soft, spherical powder that acts as a film-former and texture refiner. In a sunscreen it adds a silky slip and a soft-focus, blurring effect while helping absorb excess oil for a smoother, more matte finish. It is common in tinted and base-style sunscreens where look and feel matter as much as protection.

Is Hdi/Trimethylol Hexyllactone Crosspolymer safe?

Yes, as used in cosmetics. It is an inert polymer powder that sits on the surface of the skin to improve feel and finish, and it is widely used in foundations, primers and sunscreens. It is generally well tolerated and is not known to be irritating at the levels used.

Does Hdi/Trimethylol Hexyllactone Crosspolymer clog pores?

Generally no. It is a lightweight powder that absorbs oil and refines texture rather than an occlusive oil or wax, so it is not a typical pore-clogging ingredient. In fact its oil-absorbing, mattifying action is often welcomed by people with oilier skin.

What is Hdi/Trimethylol Hexyllactone Crosspolymer on an ingredient list (INCI)?

On the label it appears as its full INCI name, Hdi/Trimethylol Hexyllactone Crosspolymer. The name describes a crosslinked polymer powder; the slashes simply list the building blocks it is made from. It usually appears in the middle of the list, alongside the other texture and finish ingredients.

Is Hdi/Trimethylol Hexyllactone Crosspolymer a UV filter?

No. It is a texture and finish ingredient, not a sunscreen filter, so it does not provide SPF on its own. The sun protection comes from the dedicated UV filters listed separately. This crosspolymer is there to give the product its silky slip, blur and matte feel.
