About

Sulfacetamide is a cosmetic ingredient. Exercise caution due to limited available safety data.

Sulfacetamide is a sulfonamide-class antibacterial agent historically used in topical formulations for acne and rosacea. It carries H317 (skin sensitization), H335 (respiratory sensitization), and H341 (suspected mutagen) hazard statements. While formerly used in prescription topical medications, its use in cosmetics is highly restricted in the EU due to sulfonamide hypersensitivity concerns and the availability of safer alternatives.

Known concerns

  • Skin sensitization risk (H317)
  • Respiratory sensitization (H335)
  • Suspected mutagen (H341)
  • Sulfonamide hypersensitivity risk
  • Restricted in EU cosmetics
