Abstract

A colored, soap-gelled composition, comprising an alcohol, a soap in an amount effective to gel the composition, an alkali metal bicarbonate, and an inorganic pigment. Whereas alkali metal bicarbonate deodorant compositions colored with FD & C or D & C colorants do not exhibit stable color for extended periods of time, the compositions of the present invention, using inorganic pigments, exhibit stable color for extended periods, even under accelerated, e.g., high temperature, conditions.
