A composition, comprising:
- (A) at least one steroid selected from the group consisting of DHEA, a biological precursor of DHEA, a chemical derivative of DHEA, and a metabolic derivative of DHEA, and
- (B) at least one 2-alkylalkanol comprising from 12 to 36 carbon atoms or an ester thereof,
- wherein the biological precursor of DHEA is selected from the group consisting of Δ5-pregnenolone, 17α-hydroxypregnenolone, and 17αhydroxypregnenolone sulfate;
- wherein metabolic derivative of DHEA is selected from the group consisting of Δ5-androstene-3,17-diol, Δ4-androstene- 3,17-dione, 7-hydroxy-DHEA, and 7-keto-DHEA;
- and
- wherein the chemical derivative of DHEA is selected from the group consisting of DHEA salts and DHEA esters.
A method of solubilizing a steroid selected form the group consisting of DHEA, a biological precursor of DHEA, a chemical derivative of DHEA, and a metabolic derivative of DHEA in a composition containing the steroid, comprising incorporating into the composition an amount of at least one 2-alkylalkanol comprising from 12 to 36 carbon atoms or an ester thereof effective to solubilize the steroid in the composition,
- wherein the biological precursor of DHEA is selected from the group consisting of Δ5-pregnenolone, 17α-hydroxypregnenolone, and 17α-hydroxypregnenolone sulfate;
- wherein the metabolic derivative of DHEA is selected from the group consisting of Δ5-androstene-3,17-diol, Δ4-androstene- 3,17-dione, 7-hydroxy-DHEA, and 7-keto-DHEA;
- and
- wherein the chemical derivative of DHEA is selected from the group consisting of DHEA salt and DHEA ester.
