Abstract:
1. A method for producing a composition for topical application, the method comprising: a) hydrolyzing a source composition including an isoflavone in an acidic solution, wherein the isoflavone loses a sugar component and is converted into an aglycone during hydrolysis; b) adding water to the acidic solution to produce a first precipitate that includes the aglycone; c) dissolving the first precipitate in an alcohol solution, wherein the aglycone joins the alcohol solution; d) separating the alcohol solution including the aglycone from undissolved portions of the first precipitate; e) removing the alcohol from the separated alcohol solution to produce a second precipitate of solids that were dissolved in the alcohol, wherein the second precipitate includes the aglycone; and f) dissolving the second precipitate including the aglycone in an organic solvent to produce a composition suitable for inclusion in a dermatological or cosmetic preparation.
