Caution

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

A tetrahydrothiopyranyl cyclohexenone bearing both skin-sensitisation and reproductive toxicity hazard statements, making it unsuitable for cosmetic ingredient use.

This cyclohexenone derivative (CAS 94723-86-1) features a unique tetrahydrothiopyran ring fused to a 2-butyryl-3-hydroxycyclohex-2-en-1-one core. The hazard profile is significant: H302 (oral toxicity), H317 (skin sensitiser), H360 (reproductive toxicity — one of the strictest EU cosmetic prohibition triggers), and H412 (aquatic chronic toxicity). The combination of H317 and H360 in a single molecule presents a particularly high-concern regulatory profile under EU Regulation 1223/2009, making it highly likely to appear on Annex II.

Known concerns

  • H360 — reproductive toxicity / possible birth defects (CMR Cat 1B)
  • H317 — skin sensitiser — allergy and contact dermatitis risk
  • H302 — harmfulful if swallowed
  • H412 — harmful to aquatic life with long-lasting effects
  • CMR Cat 1B classification — strongly suggests EU Annex II ban
