Does Kylie Cosmetics Have Microplastics? The Ten Purity Badges

Ten badges, and the one that is missing

Go to a Kylie Cosmetics product page and you are shown a row of circular purity icons. As published on kyliecosmetics.com on 30 July 2026, the set is:

vegan · cruelty free · clean · talc free · gluten free · tear free · paraben free · fragrance free · sulfate free · hypoallergenic

In July 2021, Coty announced the relaunch of the brand with “clean and vegan” formulas, stating that the new products excluded animal oils, parabens and gluten, and banned a list of over 1,600 other ingredients.

Sixteen hundred is a genuinely large number, and this is not a gotcha about Kylie specifically. It is the shape of the entire clean-beauty category. These lists are built around toxicological hazard, preservatives, surfactants, allergens, endocrine-disruption candidates. Synthetic polymer microparticles are not a toxicological hazard in that sense. They are chemically inert. Their problem is persistence, and no clean standard is built to catch persistence.

So a product can be vegan, cruelty free, clean, talc free, paraben free, sulfate free and hypoallergenic and still contain polyethylene. That is not hypocrisy; it is a category error that the whole industry shares. We wrote about the mechanics of it in clean beauty's plastic loophole.

What the ingredient lists actually show

And the one people ask about most, the Matte Liquid Lipstick, as published by Kylie Cosmetics:

Isododecane, Mica, Dicalcium Phosphate, Octyldodecanol, Hydrogenated Styrene/Isoprene Copolymer, Stearalkonium Hectorite, Alcohol, Flavor (Aroma), Water (Aqua), Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate, Tin Oxide, Red 7 Lake (CI 15850), Iron Oxides (CI 77491, CI 77492), Blue 1 Lake (CI 42090), Titanium Dioxide (CI 77891), Yellow 5 Lake (CI 19140), Red 28 Lake (CI 45410).

No solid polymer particles. The hydrogenated styrene/isoprene copolymer is a synthetic elastomeric binder, the thing that gives a liquid lipstick its flexible, non-cracking film. It is not supplied as discrete solid particles, so it does not meet the EU definition. Sixteen of the twenty Kylie formulas we captured came out this way.

We read 20 distinct formulas from kyliecosmetics.com's own product pages. This is a sample of the catalogue rather than a census.

Is polyethylene in a lip liner a problem?

Proportionally, this is the mildest finding in our whole audit, and it would be dishonest to inflate it.

Polyethylene in a pencil is a wax-structure hardener. It is present at low concentration, it is bound in a wax matrix rather than supplied as free-flowing microbeads, and a lip liner is used in milligram quantities. Compared with a loose powder built on nylon microspheres, or PET glitter designed to shed, it is a minor case.

It still meets the definition, and it will still need to change for the EU market by 17 October 2035. But if you are prioritising, the pencil is near the bottom of the list. The powder is at the top.

The swaps

• Lip liners: pencils structured on candelilla or carnauba wax instead of polyethylene. The wax type is normally in the first five ingredients.
• Long-wear foundation: harder. Silicone elastomers are what deliver the blurred, long-wear finish, and the alternatives, more traditional emulsions, wear differently. This is a genuine trade-off, not a free swap.
• If you like the Matte Liquid Lipstick: keep it. It passes this test.

This is one of five brand breakdowns from our audit of 81 formulas across Fenty, Huda Beauty, rhode and Kylie Cosmetics. See also Fenty Beauty, Huda Beauty, and rhode.
