Abstract: A dry aerosol antiperspirant composition containing an astringent powder, an aerosol propellant, and a di(C.sub.8-10 alkanoate) of a C.sub.2-6 alkylene diol such as propylene dipelargonate, and method of using same.

Abstract: An improved antiperspirant composition is prepared by spray drying together a mixture of aluminum chloride, aluminum chlorhydrate, and urea. The impalpable powder which is formed is incorporated into an aerosol antiperspirant formulation.

Abstract: Nonaqueous compositions, especially cosmetic preparations such as shaving creams, are rendered self-heating by including therein a compound containing at least one boron-oxygen-boron linkage, such as triethoxyboroxine, which reacts exothermically with water or other protic material.

Abstract: An improved antiperspirant composition can be prepared by co-spray drying together a mixture of aluminum chloride, aluminum chlorhydrate, and urea. The co-spray drying technique produces an impalpable powder which may be incorporated into an antiperspirant formulation suitable for aerosol application.

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.
