The composition also preferably contains a polyhydroxyl compound, such as a glycol or a polyglycol in an amount of from about 0.5 to about 10 weight percent. The compositions are useful as deodorant sticks, perfume sticks, sun sticks, hand lotion sticks, talc sticks, pigment sticks and insect repellant sticks.
