About

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

Ethyl hydroxypyrone (2-ethyl-3-hydroxy-4H-pyran-4-one, also known as ethyl maltol) is a pyrone derivative used for its sweet, warm, caramel-like fragrance and flavor properties. The SCCS has noted contact allergy concerns at concentrations exceeding 0.001% in leave-on products; however, it is not listed in EU Cosmetics Regulation Annexes II–VI. When used at appropriate levels in rinse-off or properly formulated leave-on products, sensitization risk is low.

Skin benefits

  • fragrance material with sweet, warm character
  • enhances sensory experience of cosmetic formulations

Known concerns

  • contact allergy concern at high concentrations (SCCS notes >0.001% in leave-on products)
