About

ISOBUTYL-METHOXYPYRAZINE is a cosmetic ingredient used in product formulation. Exercise caution due to limited available safety data.

Isobutyl-methoxypyrazine is a substituted pyrazine functioning as a fragrance ingredient with powerful green, earthy, and vegetable-like odor characteristics at very low concentrations. Pyrazines in general are known sensitisers at high concentrations, though this specific compound is not listed on EU Annex II or III restrictions. The methoxy and isobutyl substituents increase its lipophilicity and potential for skin penetration, warranting attention to use levels in finished products.

Skin benefits
