<p>Soap-based clear cosmetic sticks are disclosed which include an alkali metal salt of a chelating agent into the stick composition to increase the set temperature and the stick hardness and to prevent the formation of precipitates in the composition during aging. A typical composition of the present invention comprises about 40 to 90 %, preferably about 50 to 80 %, of a polyhydric alcohol, about 5 to 35 %, preferably 15 to 30 %, water, about 3 to 12 %, preferably 4 to 8 %, of an alkali metal salt of a C12-22, preferably C14-18, fatty acid, and about 0.3 to 1.6 %, preferably about 0.5 to 1.3 % of an alkali metal salt of a chelating agent, preferably a sodium or potassium salt of ethylene diamine tetraacetic acid (EDTA). The composition will also typically contain a cosmetic active ingredient such as a deodorant active.
