Abstract

The hydroxybenzoate compounds of this invention are defined by the formula: ##STR1## wherein Y is hydrogen, hydroxy, halo, a C.sub.1 to C.sub.6 alkyl or a C.sub.2 to C.sub.6 alkyl ether; R is a C.sub.4 to C.sub.6 mono- or di-olefinically unsaturated hydrocarbon radical, a C.sub.4 to C.sub.7 mono- or di-acetylenically unsaturated hydrocarbon radical or a C.sub.2 to C.sub.3 acetylenically unsaturated hydrocarbon radical when at least one of X and Y is other than hydrogen and X is hydrogen, hydroxy, halo, a C.sub.1 to C.sub.6 alkyl, a C.sub.2 to C.sub.6 alkyl ether or ##STR2## in which A is selected from the group of X, B is selected from the group of Y and R.sub.1 is hydrogen, hydroxy, C.sub.1 to C.sub.6 alkyl, C.sub.1 to C.sub.6 alkoxy or --COOR.sub.2 in which R.sub.2 is C.sub.1 to C.sub.6 alkyl, a C.sub.2 to C.sub.6 olefinically unsaturated hydrocarbon radical or a C.sub.2 to C.sub.7 acetylenically unsaturated hydrocarbon radical. The invention also pertains to food, beverage, cosmetic, agrichemical and topically applied pharmaceutical compositions containing an effective preservative amount of the hydroxy aliphatically unsaturated benzoate having the formula: ##STR3## wherein X' is selected from the group of X; Y' is selected from the group of Y and R.sub.4 is a C.sub.2 to C.sub.6 mono- or di-olefinically unsaturated hydrocarbon radical or a C.sub.2 to C.sub.7 mono- or di-acetylenically unsaturated hydrocarbon radical.
