| abstract | 1308565 Self-heating shaving creams GILLETTE CO 18 June 1970 [25 June 1969] 29619/70 Heading C5D [Also in Division A5] A self-heating pharmaceutical or cosmetic composition comprises a vehicle and a first and a second heat-generating component, maintained separately from one another but which when in contact with one another effect an exothermic reaction; at least one of said components being encapsulated in a plurality of frangible capsules which are dispersed in said vehicle, the encapsulating material for said capsules being both inert and impermeable with respect to the vehicle and the heat-generating components. During use, the capsules are ruptured by mechanical force to allow the heatproducing components to react. The encapsulating material preferably has a melting point at or below the temperature produced when the heat-generating components react, whereby (a) the capsule fragments are readily dispersed in the composition to produce a smooth preparation in use, (b) the heating may be prolonged by using excess of the heat-generating components and initially rupturing only a portion of the capsules, (c) the heating may be raised to a desired level over a prolonged period by incorporating the heat-generating components in a plurality of thermoplastic capsules which have sequentially higher melting points, e.g. 120 F., 140 F. and so on. Any heat-generating components may be used provided they are non- toxic and non-irritating. Preferred are mixtures of (a) oxidizing agents, e.g. chlorates, perchlorates, permanganates, persulphates, peroxides, nitrates, metal oxides and perborates and (b) reducing agents, e.g. magnesium, zinc, aluminium, sulphites, thiosulphates, aldehydes, glycols and derivatives of thiobarbituric acid. A shaving cream formulation contains 1-phenyl- 5 - ethyl - 2 - thiobarbituric acid (reductant), ammonium molybdate tetrahydrate (catalyst) and aqueous hydrogen peroxide encapsulated in beeswax as the heat-producing components. A single-use packet (Figs. 1 and 2) comprises an enclosed chamber containing the self-heating composition and having at least one resilient wall and a dispensing opening which is closed off by a removable closure. Specification 1,088,301 is referred to. |
