About
Methyl Ethylacetoacetate is a cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.
Methyl ethylacetoacetate is a β-keto ester bearing an ethyl substituent, functioning as a fragrance ingredient and formulation solvent in cosmetic products. Its structure is similar to other safe acetoacetate derivatives; no EU cosmetic restrictions apply, and it is not listed in Annexes I–VI of the Cosmetic Regulation. It is considered to have low systemic toxicity at cosmetic-use concentrations.
