About

Tolualdehyde Isomers is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Tolualdehyde isomers (o-, m-, p-cresaldehyde) are aromatic aldehydes functioning as fragrance ingredients with sweet, floral, and slightly phenolic olfactory characteristics. No GHS hazard statements are recorded, though as with all aldehydes, mild skin and eye irritation is theoretically possible. EU CosIng does not list this mixture on Annex II (banned) or Annex III (restricted) lists. SCCS and IFRA have not flagged major concerns at typical use concentrations of 0.1-2% in finished products.

Skin benefits

  • Contributes sweet floral fragrance notes
  • Used as fragrance component in cosmetic formulations

Known concerns

  • Minor aldehyde irritation potential
  • May require standard fragrance allergen declaration per EU regulation 1223/2009
