Abstract:
1. A method of stabilizing a body care product selected from the group consisting of skin-care products, hair-care products, dentrifrices, and deodorizing and antiperspirant preparations, wherein said method comprises incorporating therein or applying thereto one or more stabilizing compounds of the formulae A* wherein E is —O-T-(OH) T is a straight or branched chain alkylene of 1 to 18 carbon atoms, cycloalkylene of 5 to 18 carbon atoms, cycloalkenylene of 5 to 18 carbon atoms, a straight or branched chain alkylene of 1 to 4 carbon atoms substituted by phenyl or by phenyl substituted by one or two alkyl groups of 1 to 4 carbon atoms; b is 1, 2 or 3 with the proviso that b cannot exceed the number of carbon atoms in T, and when b is 2 or 3, each hydroxyl group is attached to a different carbon atoms of T; R is hydrogen or methyl; and in formula (A*) n is 1 or 2, when n is 1, R when n is 2, R HY is an inorganic or organic acid; wherein the total charge of cations is equal to the total charge of anions; and Y is phosphate, phosphonate, carbonate, bicarbonate, nitrate, chloride, bromide, bisulfite, sulfite, bisulfate, sulfate, borate, formate, acetate, benzoate, citrate, oxalate, tartrate, acrylate, polyacrylate, fumarate, maleate, itaconate, glycolate, gluconate, malate, mandelate, tiglate, ascorbate, polymethacrylate, a carboxylate of nitrilotriacetic acid, a carboxlylate of hydroxyethylethylenediaminetriacetic acid, a carboxylate of ethylenediaminetetraacetic acid, a carboxylate of diethylenetriaminepentaacetic acid, a carboxylate of diethylenediaminetetraacetic acid, a carboxylate of diethylenetriaminepentaacetic acid, alkylsulfonate, arylsulfonate, or alkyl-substituted arylsulfonate.
