ABSTRACT:
Described herein is a method for making a flake for use in a topical application. The flake is formed by contacting a liquid phase waxy material that may contain pigments, fragrance, plasticizer, hydrophilic modifier with a pseudoplastic hydrophilic gel, and/or an active ingredient. The waxy material contacts the surface of the gel and after the two materials have contacted, the waxy material is solidified and forms a sheet. This sheet is then broken into pieces to form the flakes of the present invention. The flakes can be used in formulating any topical product that can contain a lipid material.
