Abstract
Abstract The compounds represented by the structural formula <IMAGE> wherein A, B and C each independently represent hydrogen or lower alkyl having from 1 to 4 carbon atoms, provided that the sum of the carbon atoms in A, B and C is no more than 5, R1 represents alkyl having from 1 to 4 carbons, have been found to be particularly useful in compositions and methods for counteracting malodors. Novel compounds are also disclosed.
