  • Patent number: 5925338
    Abstract: The present invention is directed to a clear antiperspirant or deodorant gel composition which exhibits reduced staining while retaining excellent aethetic attributes and efficacy. The gel composition is a water-in-oil emulsion having a viscosity of about 50,000 to 250,000 cP, preferably about 100,000 to 200,000 cP. The water phase comprises about 75 to 90% of the composition and contains a deodorant or antiperspirant effective amount (e.g. about 3 to 25%) of an antiperspirant active dissolved therein. The oil phase comprises about 10 to 25% of the composition and contains a silicone oil and a polyether substituted silicone emulsifying agent.

  • Patent number: 5925339
    Abstract: The invention relates to agents preventing (the formation of) human malodor. In particular, the invention relates to the use of several classes of compounds which can act as such agents in cosmetic products, such as deodorants and antiperspirants. These compounds are normally odorless or nearly so, but upon contacting the skin as for example, in skin care compositions or in personal care compositions, they prevent malodor. The compounds under consideration are compounds of the formulaX--(Z).sub.n --CO--NH--CH--(COO--Y)--CH.sub.2 CH.sub.2 CONH.sub.2IThe definition of the substituents is given in the specification.

  • Patent number: 5725836
    Abstract: A method for providing aerogels, and aerogels produced according to the method, is described. As one aspect, antiperspirant compounds that are in aerogel form, and antiperspirant and deodorant compositions including such salts, are described. The method involves contacting a solution containing material to be processed with a species selected to precipitate the material and selected so as to be miscible with the solvent system of the solution. After the material is precipitated, the material may be washed with the precipitating species until it is substantially free of solvent system. Then, the precipitating species containing the material precipitate is taken above its critical point, and the supercritical fluid is exhausted above its critical temperature. Alternately, a separate isolating species is introduced to displace the precipitating species, or the precipitating species/solvent system mixture. The isolating species then is taken above its critical point, and exhausted above its critical temperature.

  • Patent number: 5723135
    Abstract: The present invention features a method of making a gel cosmetic stick. The method comprises first mixing a particulate dibenzylidene alditol with a liquid vehicle which contains an antiperspirant salt dissolved therein to form a uniform dispersion. The dibenzylidene alditol is mixed with the liquid vehicle at a temperature sufficiently low, preferably below 50.degree. C., so that substantially none of the dibenzylidene alditol dissolves in the liquid vehicle. This dispersion may comprise a commercial size quantity, typically greater than 200 kg. A portion of this dispersion, typically a relatively small portion, is then heated to a temperature sufficient to dissolve the dibenzylidene alditol therein, then cooled to form a gel. This heating and cooling is conducted sufficiently rapidly so as to minimize degradation of the dibenzylidene alditol. Preferably the heating and cooling is conducted such that said portion is subjected to a temperature greater than 90.degree. C.
