Abstract
Disclosed are stabilized body care products, household products, textiles and fabrics which comprise certain hindered nitroxyl, hydroxylamine and hydroxylamine 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.

- (a) a body care product, household cleaning product, wherein the body care product is selected from the group consisting of:
- skin-care product,
- which skin-care products are selected from the group consisting of body oils, body lotions, body gels, treatment creams, skin protection ointments, shaving preparation and skin powders, bath and shower product, preparations containing fragrances and odoriferous substances,
- hair-care products which hair-care products are selected from the group consisting of shampoos for humans and animals, hair conditioners, 2 in 1 conditioners, leave in and rinse off conditioners, products for styling and treating hair, perming agents, hair sprays and lacquers, hair gels, hair fixatives, relaxants, hair dyeing systems, permanent, demi-permanent, semi-permanent and temporary hair dyeing systems, and hair bleaching agents, dentifrices, deodorizing and antiperspirant preparations,
- cosmetic formulations containing active ingredients, which active ingredients are selected from the group consisting of hormone preparations, vitamin preparations, vegetable extract preparations and antibacterial preparations,
- decorative preparations which decorative preparations are selected from the group consisting of lipsticks, nail varnishes, eye shadows, mascaras, dry and moist make-up, rouge, powders, depilatory agents and suntan lotions,
- and
- the household cleaning product is selected from the group consisting of liquid cleansing and scouring agents, glass detergents, bathroom cleaners, washing, rinsing and dishwashing agents, kitchen and oven cleaners, clear rinsing agents, dishwasher detergents, shoe polishes, polishing waxes, floor detergents and polishes, metal, glass and ceramic cleaners, furniture and multipurpose polishes and leather and vinyl dressing agent and solid and liquid air fresheners,
- (b) an effective stabilizing amount of 5 to about 10000 ppm, based on the total composition,
- at least one compound selected from the group consisting of
- (iii) hindered hydroxylamine salt compounds of formula
- where
- in formula A*,
- n is 1 or 2,
- when n is 1,
- R1 is hydrogen, alkyl of 1 to 18 carbon atoms, alkenyl of 2-18 carbon atoms, propargyl, glycidyl, alkyl of 2 to 50 carbon atoms interrupted by one to twenty oxygen atoms, said alkyl substituted by one to ten hydroxyl groups or both interrupted by said oxygen atoms and substituted by said hydroxyl groups, or
- R1 is alkyl of 1 to 4 carbon atoms substituted by a carboxy group or by —COOZ where Z is hydrogen, alkyl of 1 to 4 carbon atoms or phenyl, or where Z is said alkyl substituted by —(COO−)nMn+ where n is 1-3 and M is a metal ion from the 1st, 2nd or 3rd group of the periodic table or is Zn, Cu, Ni or Co, or M is a group Nn+(R2)4 where R2 is alkyl of 1 to 8 carbon atoms or benzyl,
- when n is 2,
- R1 is alkylene of 1 to 12 carbon atoms, alkenylene of 4 to 12 carbon atoms, xylylene or alkylene of 1 to 50 carbon atoms interrupted by one to twenty oxygen atoms, substituted by one to ten hydroxyl groups or both interrupted by said oxygen atoms and substituted by said hydroxyl groups,
- R is hydrogen or methyl;
- X is an inorganic or organic anion, and
- where the total charge of cations h is equal to the total charge of anions j
- and
- d) a dye.
