The hydroxybenzoate compounds of this invention are defined by the formula:
wherein Y is hydrogen, hydroxy, halo, a C1 to C6 alkyl or a C2 to C6 alkyl ether;
R is a C4 to C6 mono- or di-olefinically unsaturated hydrocarbon radical, a C4 to C7 mono- or di-acetylenically unsaturated hydrocarbon radical or a C2 to C3 acetylenically unsaturated hydrocarbon radical when at least one of X and Y is other than hydrogen and
X is hydrogen, hydroxy, halo, a C1 to C6 alkyl, a C2 to C6 alkyl ether or
in which A is selected from the group of X,
B is selected from the group of Y and
R1 is hydrogen, hydroxy, C1 to C6 alkyl, C1 to C6 alkoxy or —COOR2 in which R2 is C1 to C6 alkyl, a C2 to C6 olefinically unsaturated hydrocarbon radical or a C2 to C7 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:
wherein X′ is selected from the group of X; Y′ is selected from the group of Y and R4 is a C2 to C6 mono- or di-olefinically unsaturated hydrocarbon radical or a C2 to C7 mono- or di-acetylenically unsaturated hydrocarbon radical.
