About

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

Methyl methylsalicylate is a methyl ester of a methyl-substituted salicylic acid. While structurally similar to methyl salicylate (oil of wintergreen), it has a distinct fragrance profile. The EU's scientific committees have flagged salicylates as having skin sensitisation potential at certain concentrations, and this derivative is treated with moderate caution. It is not currently listed in EU Annex III but warrants attention due to structural alerts.

Skin benefits

  • Provides distinctive fragrance in cosmetic formulations
  • May contribute to soothing aromatic profile

Known concerns

  • Potential skin sensitiser — may cause allergic contact dermatitis
  • Mild irritant to skin and eyes at high concentrations
  • Structural similarity to methyl salicylate raises concern for cross-reactivity
