About

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

Propynyloxybenzaldehyde is a phenolic aldehyde with an alkyne ether substituent, carrying H302 (oral toxicity), H312 (dermal toxicity), H315/H319 (skin/eye irritation), and H332 (inhalation toxicity). The propargylic ether structure suggests potential for metabolic activation. No EU cosmetic-specific restrictions apply, but the compound's multi-route toxicity profile warrants caution in formulation.

Known concerns

  • Acute oral toxicity (H302)
  • Dermal toxicity (H312)
  • Skin irritation (H315)
  • Eye irritation (H319)
  • Inhalation toxicity (H332)
