  • Patent number: 5270034
    Abstract: An antiperspirant stick composition is provided. The antiperspirant composition comprises: (a) from about 15% to about 25% by weight of an acidic antiperspirant active metal salt; (b) from about 1% to about 70% by weight of a polar solvent which is not a monohydric alcohol; (c) from about 5% to about 15% by weight of an aprotic solvent; (d) from about 2% to about 5% by weight of a gelling agent; and (e) from about 0.05% to about 0.3% by weight of an antimicrobial agent. The antiperspirant composition is stable without the inclusion of a stabilizing agent and also is relatively odorless and clear resulting in an aesthetically desirable antiperspirant composition which eliminates the need for masking fragrances.
