About

Methyl 2,4-dihydroxybenzoate is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Methyl 2,4-dihydroxybenzoate (or 2,4-dihydroxymethyl benzoate) is a resorcinol derivative bearing two hydroxyl groups on the benzoic acid ring. The EU GHS hazard classification includes H315 (skin irritant), H319 (eye irritant), and H335 (may cause respiratory irritation). These properties require handling precautions and limit its suitable applications in cosmetics. While not individually restricted in EU Annexes, the multiple irritation flags raise concern for use in leave-on skin products.

Skin benefits

  • May function as an antioxidant in cosmetic formulations
  • UV-absorbing properties may contribute to product stability

Known concerns

  • H315 skin irritant
  • H319 eye irritant
  • H335 respiratory irritant
  • Dihydroxybenzene structure may contribute to sensitivity reactions
  • Avoid in products applied near eyes or respiratory tract
