We checked 14 of Kosas' products, each re-checked against its product page on kosas.com on 25 October 2026 and taken from the ingredient list on that page (all shade lists where shades differ). This is a factual check of ingredient lists against our definition of clean. It is not a verdict on the brand and says nothing about how well any product works.

Key ingredient: one ingredient named in the product's published ingredient list, shown for orientation only; it is not a claim about what the product does.

What "clean" means here
On CleanGlow, a product is clean if its listed ingredients contain none of our 10 watchlist groups, based on the IARC Monographs – List of Classifications and on bans and restrictions under the EU Cosmetics Regulation (EC) 1223/2009. A product is flagged if at least one listed ingredient matches a watchlist group. The rules are the same for every brand (see the methodology). We do not judge fragrance, essential oils, performance or any marketing claim the brand makes.
Why Kosas products get flagged
Titanium dioxide (8 Kosas products)
IARC classifies titanium dioxide as Group 2B ("possibly carcinogenic to humans"), based on evidence from inhaling the powder. We flag every product that lists it, including where it is only a pigment, an opacifier or a "may contain" shade pigment, and including mineral sunscreens that use it as a UV filter. A flag means the ingredient is on the list. It is not a measured risk for that product. Source: IARC Monographs Vol. 93. See Titanium dioxide for every product we flag for it.
Every Kosas product we checked
Ingredient lists come from kosas.com (fetched 25 October 2026) unless the source column says otherwise. Formulas change and can differ by country, so always check the pack.
Shades: where shades of one Kosas product publish different ingredient lists (for example Lip Pulse and Wet Lip Oil Gloss), we checked every shade list on the page, so a product is flagged if any shade lists a watchlist ingredient. Where to buy: the buttons go to kosas.com, plus Sephora (a matched product page where we have one, otherwise a Sephora search). We have no verified Kosas brand store on Amazon and found no Amazon product link on kosas.com, so there is no Amazon button; Kosas is not in Ulta's brand list, so there is no Ulta button.

Clean alternatives by product type

We match on product category only. They are not presented as equivalents: we have not tested them and make no claim that they look, feel or work like the Kosas product.

Hazard is not risk. An IARC classification says whether a substance can cause cancer under some conditions (e.g. titanium dioxide is classified for inhaled powder), not that a cosmetic containing it is harmful at normal use. EU restrictions set use limits. This page is informational, not medical advice; talk to a dermatologist about your own skin.
