ABSTRACT:
The present invention relates to methods of making enhanced efficacy antiperspirant salts and particularly stabilized aqueous polyhydric alcohol solutions of such salts. One such method involves stabilizing an aqueous solution of an enhanced efficacy antiperspirant salt by adding an effective amount of a polyhydric alcohol having from 3 to 6 carbon atoms and from 3 to 6 hydroxyl groups. A second disclosed method involves preparing an enhanced efficacy aluminum antiperspirant salt by heating an aqueous solution of an aluminum antiperspirant salt in the presence of a polyhydric alcohol having from 3 to 6 carbon atoms and from 3 to 6 hydroxyl groups at a temperature of at least 50.degree. C. for a time sufficient to convert the salt to an enhanced salt. A third disclosed method is an improvement in the method of making an aluminum hydroxy halide or an aluminum hydroxy nitrate by reacting aluminum with an aqueous solution of aluminum halide or aluminum nitrate (or with aqueous hydrogen halide or nitric acid), wherein the improvement comprises including a polyhydric alcohol having from 3 to 6 carbon atoms and from 3 to 6 hydroxyl groups in the reaction mixture. Also disclosed are compositions produced by the foregoing methods.
