About
A fruity-green allyl ester fragrance ingredient. Allyl esters as a class have IFRA restrictions and sensitisation concerns — use at low levels only.
Allyl 2-methylbutoxyacetate (CAS 67634-01-9) is an allyl ester fragrance ingredient with a fresh, fruity character used in fine fragrance and personal-care perfume compounds. Allyl esters as a chemical class have drawn IFRA attention because several members show skin-sensitisation potential and, in some cases, genotoxicity flags in QSAR/in-vitro screens. IFRA Standards apply strict concentration limits depending on product category. Public peer-reviewed dermal-toxicology literature on this specific material is limited. Consumer concentrations in finished cosmetics are typically <0.1%.
