    摘要: The present invention comprises a process of preparing a solution of an enhanced efficacy aluminum antiperspirant salt in a polyhydric alcohol by (a) providing an aqueous solution consisting essentially of about 5 % to about 18 % by weight of an enhanced efficacy aluminum antiperspirant salt in water, the enhanced efficacy aluminum antiperspirant salt having been prepared in situ without having been dried to a solid powder; (b) mixing the aqueous solution with a sufficient amount of a liquid polyhydric alcohol to provide a mixed solution which has an antiperspirant salt to polyhydric alcohol ratio of about 1:4 to about 1.2:1; and (c) rapidly evaporating the water from the mixed solution under vacuum to provide a final liquid polyhydric alcohol solution containing about 20 to 50 % enhanced efficacy aluminum antiperspirant salt and about 2 to 16 % water, with the balance being polyhydric alcohol. An alkaline glycinate salt, such as sodium, potassium or zinc glycinate, may be added to the polyhydric alcohol prior to the addition of the antiperspirant salt solution in order to raise the pH of the recovered product to about 4.1 to 5.0.

    摘要: Disclosed are enhanced efficacy aluminum-zirocnium antiperspirant salt compositions which exhiit an HPLC peak 5 area content of about 33 % or more, preferably at least 45 %, more preferably at least 50 %, most preferably at least 55 %. Especially preferred are aluminum-zirconium antiperspirant salt composition which, in addition to the aforementioned high peak 5 content, also exhibit an HPLC peak 4 to peak 3 area ratio of at least 0.4, preferably at least 0.7. The aforementioned salt compositions will preferably have a metal (Al + Zr) to chloride (or anion) ratio of about 0.90 to about 1.00. Also disclosed are methods of making such antiperspirant salt compositions and aqueous solutions of such antiperspirant sald compositions. Further disclosed are topical compositions comprising a dermatologically acceptable carrier vehicle and a perspiration reducing effective amount of an aluminium-zirconium antiperspirant salt composition as described above.
