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. |
