Malodor counteractant compositions

Abstract

A composition is provided for MOC that contains compounds with the structure: wherein R 1 is a hydrogen, an alkyl, an alkoxy, or a substituted or unsubstituted aryl group; R 2 is an alkyl having greater than 6 carbons, a substituted aryl, or unsubstituted aryl. Preferably these compounds have a low odor intensity. These compounds may be used with other MOC ingredients that act synergistically or additively with them.
