Abstract

A method of producing a lipophilic liposomal composition includes the step of forming a liposome forming composition by admixing at an elevated temperature at least one lipophilic ingredient selected from a group consisting of pharmaceutical lipophilic ingredients, cosmetic lipophilic ingredients, and cosmeceutical lipophilic ingredients; a liposome-forming lipid component; and, a solubliizer for the liposome-forming lipid component. The resulting liposome forming composition is then cooled.

Claims

(a) forming a liposome forming composition by admixing at an elevated temperature

(i) at least one lipophilic ingredient selected from a group consisting of pharmaceutical lipophilic ingredients, cosmetic lipophilic ingredients, and cosmeceutical lipophilic ingredients,

(ii) a liposome-forming lipid component, and

(iii) a solubliizer for said liposome-forming lipid component;

(b) cooling said liposome forming composition to form loaded liposomes.
