Method of preparing enhanced efficacy aluminum chlorhydrate antiperspirant and antiperspirant composition. |
摘要 |
<p>Two-thirds to five-sixths basic aluminum chlorides having enhanced antiperspirant efficacy are produced by heating an aqueous solution containing about 40 to about 50 weight percent of the basic aluminum chloride to a temperature of at least about 130 degrees C for about one to twelve hours in a closed vessel, with the heating time being inversely proportional to the temperature. Five-sixths basic aluminum chlorides treated in this manner are characterized by a size exclusion chromatogram having a single major peak with its apex at a relative retention time of about 0.75 - 0.79. The basic aluminum chlorides may be incorporated into any of the conventional antiperspirant forms with non-toxic, dermatologically acceptable carriers.</p> |
