Abstract
The invention discloses ketones of formula I: ##STR1## wherein, PA0 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; PA0 R.sup.1 is hydrogen or a C.sub.1-6 alkyl group that is substituted, saturated or unsaturated, straight or branched; PA0 A is a chromophoric substituted aromatic ring or ring system; PA0 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.
