Safety score · 0–100

Fine

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

A small aromatic sulfonamide used as a specialty cosmetic building block, with irritation as the main concern.

4-Tosylamide is not a hero skincare ingredient; it is a small aromatic compound used in specialty formulations. Available hazard data mainly point to eye irritation, without the much harsher profile seen in high-risk solvents. That makes it middling rather than alarming, but not especially skin-loving.
