The invention discloses ketones of formula I:
wherein,
Y is an optionally substituted alkyl, cycloalkyl, or cycloalkylalkyl, wherein each alkyl group is straight or branched and each alkyl and cycloalkyl group is saturated or unsaturated;
R1 is hydrogen or a C1-6 alkyl group that is substituted, saturated or unsaturated, straight or branched;
A is a chromophoric substituted aromatic ring or ring system;
n is an integer; and
with the proviso that formula I is not 2-ethoxy-1-phenyl-ethanone. These compositions are useful for the delivery of organoleptic compounds, especially of flavors, fragrances, masking agents and antimicrobial compounds.
