Ingredient Ratings

Overall Rating

Good

Comedogenic Risk

None

Skin Benefits

Creates a velvety finish that helps mattify and smooth the look of skin. Diffuses light to soften the appearance of pores and uneven texture.

Uses In Skincare & Cosmetics

Common in makeup primers, setting powders, and long-wear foundations to improve glide and extend wear. Also used in oil-controlling moisturizers for a soft-touch feel.

Comedogenic Rating

This ingredient is not typically evaluated for comedogenicity, and no standardized rating is available.

Safety

Considered low irritation in leave-on and rinse-off products. Avoid inhaling loose powders; the cured polymer does not contain free isocyanates in finished cosmetics. Suitable for most skin types, including oily and combination.

Is HDI/Trimethylol Hexyllactone Crosspolymer a Good Ingredient?

It's Good because it's a stable, inert polymer that reliably blurs texture and absorbs oil with a low likelihood of irritation, and its slip and mattifying performance in makeup and primers is well established. That's dependable formulation performance rather than a treatment benefit, which is why it stops at Good.
