Abstract
Disclosed are stabilized body care products, household products, textiles and fabrics which comprise certain sterically hindered amine salt compounds. Dyed products and articles are effectively stabilized against color degradation. The products are for example skin-care products, hair-care products, dentifrices, cosmetics, laundry detergents and fabric softeners, non-detergent based fabric care products, household cleaners and textile-care products.
Claims9
A stabilized composition comprising
- (a) a body care product selected from the group consisting of skin-care products, hair-care products, dentifrices, and deodorizing and antiperspirant preparations, and
- (b) from about 5 ppm to about 10000 ppm, based on the total formulation by weight, of one or more compounds selected from the group consisting of formulae (B*)
- wherein
- E is alkoxy of 1 to 18 carbon atoms, cycloalkoxy of 5 to 12 carbon atoms or aralkoxy of 7 to 15 carbon atoms, or E is —O-T-(OH)b,
- 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 (B*), m is 1 to 4, and
- when m is 1,
- R2 is cycloalkyl of 5 to 12 carbon atoms,
- when m is 2,
- cycloalkylene of 5 to 12 carbon atoms, aralkylene of 7 to 15 carbon atoms or arylene of 6 to 12 carbon atoms,
- when m is 3,
- R2 is alkanetriyl of 3 to 8 carbon atoms or benzenetriyl, or
- when m is 4,
- R2 is alkanetetrayl of 5 to 8 carbon atoms or benzenetetrayl,
- HY is an inorganic or organic acid;
- wherein the total charge of cations is equal to the total charge of anions;
- and
- Y is selected from the group consisting of 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, and alkyl-substituted arylsulfonate.
