Abstract: A method of bleaching fabrics, effective to remove stains and safe for dyed fabrics, includes bleaching such a fabric in an aqueous medium containing bleaching composition including a water soluble peroxymonosulfate bleach, a water soluble inorganic bromide which promotes the bleaching activity of the peroxymonosulfate and an N-hydrogen compound of a certain type, such as para-tolulenesulfonamide or 5,5 dimethylhydantoin which inhibits destruction of dyes and overbleaching of dyed materials while stains to be bleached are effectively removed. Washing may also be effected with the bleaching in which case bleaching detergent composition are employed, which also contain a normally solid, water synthetic organic detergent, such as an anionic detergent, which may be a sodium linear higher alkylbenzenesulfonate or a higher fatty alcohol polyethylene oxide condensate, or a mixture thereof. Such compositions and the aqueous washing media may also include a builder salt.

Abstract: A packaged self-heating cosmetic, such as a shaving cream, hand lotion, depilatory, facial, or a shampoo, including separate exothermically reactive reductant material, such as 2-thio-4-oxypyrimidine or thiohydantoin or derivatives thereof, and an oxidant, which reacts with the reductant, generating heat. Means are provided for dispensing the packaged reductant and oxidant from separate zones and bringing them into contact with each other so that they react and heat a pressurized shaving cream or other cosmetic product whose constituents the exothermic reaction mixture contacts. The reducing agent employed is preferably 2-thio-4-oxypyrimidine or its tautomer, 2-mercapto-4-hydroxypyrimidine, or alkyl-substituted derivative thereof, and the oxidizing agent is preferably aqueous hydrogen peroxide.
