About

O-Hydroxy- benzaldehyde is a cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.

Salicylaldehyde (2-hydroxybenzaldehyde) is an aromatic aldehyde with well-documented skin sensitization and irritation properties. It is not specifically listed in EU Annex II or III of Regulation 1223/2009, but its aldehyde structure and phenolic hydroxyl group contribute to its sensitizing potential. It shows moderate acute toxicity and has been associated with allergic contact dermatitis. Restricted by IFRA in fragrance applications due to its sensitizing profile.

Known concerns

  • Skin sensitizer (aldehyde)
  • Skin and eye irritation
  • IFRA restrictions apply
