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.
