Detailed Analysis
2,3-Dimethyl-4-Formyl-1-Phenyl-5-Pyrazolone is an aromatic heterocyclic compound bearing both aldehyde and methyl substituents on a phenylpyrazolone scaffold. Its aldehyde group is a key driver of its reactivity and irritation potential. It is not listed on any EU Annex (II–VI), indicating no specific cosmetic ban, but the GHS hazard profile (H315 skin irritation, H319 serious eye irritation, H335 respiratory irritation) combined with limited cosmetic usage history suggests caution and a relatively low safety margin in leave-on products.
