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.
