About
A photoinitiator chemical suspected of damaging fertility — highly toxic to aquatic life and not a typical cosmetic ingredient.
Isopropyl Thioxanthone (ITX) is primarily used as a UV photoinitiator in printing inks, not as a cosmetic active. GHS classifications include H302 (harmful if swallowed), H361/H361f (suspected of damaging fertility — reproductive toxicity), and H400/H410 (very toxic to aquatic life). The reproductive toxicity classification is particularly concerning. Its presence in cosmetics would likely be as a contaminant from packaging rather than intentional use.
