About

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

Methyl thiazolyl ketone (2-acetylthiazole) is a five-membered heterocycle containing both sulfur and nitrogen (thiazole ring) with a ketone substituent. Thiazole derivatives are widely used in flavour and fragrance industries for their meaty, cooked, and roasted aromatic qualities. Acute toxicity data show low concern, and no EU Annex restrictions apply specifically to this substance. However, as a heterocyclic compound, it warrants evaluation in the context of skin sensitisation potential.

Skin benefits

  • Provides distinctive cooked/meaty fragrance notes in cosmetic products
  • Contributes to complex aromatic profile in specialty fragrances

Known concerns

  • Heterocyclic thiazole structure may cause mild skin irritation
  • Limited specific cosmetics chronic toxicology data
  • Strong aroma may trigger sensitivity in fragrance-sensitive individuals
