Abstract
Disclosed are stabilized body care products, household products, textiles and fabrics which comprise certain hindered nitroxyl, hydroxylamine and hydroxylamine salt compounds and selected organic UV filters. The stabilized 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.
Claims40
A stabilized composition comprising
- (a) a body care product, household product, textile or fabric,
- (b) an effective stabilizing amount of at least one compound selected from the group consisting of
- (i) hindered nitroxyl compounds of formula (I)
- (ii) hindered hydroxylamine compounds of formula (II)
- (iii) hindered hydroxylamine salt compounds of formula (III)
- wherein
- G1 and G2 are independently alkyl of 1 to 4 carbon atoms or are together pentamethylene,
- Z1 and Z2 are each methyl, or Z1 and Z2 together form a linking moiety which may additionally be substituted by an ester, ether, hydroxy, oxo, cyanohydrin, amide, amino, carboxy or urethane group,
- X is an inorganic or organic anion, 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, hydroxyethylethylenediaminetriacetic acid, ethylenediaminetetraacetic acid or of diethylenetriaminepentaacetic acid, a diethylenetriaminepentamethylenephosphonate, an alkylsulfonate or an arylsulfonate, and
- where the total charge of cations h is equal to the total charge of anions j;
- and
- (c) an organic UV filter selected from
- (c1) dibenzoylmethane derivatives;
- (c2) cinnamic acid esters;
- (c3) camphor derivatives;
- and
- (c4) trianilino-s-triazine derivatives.
