METHOD FOR DEVELOPING A LIQUID COMPOSITION TO BE APPLIED TO THE SKIN AS A FOAM AND A COMPOSITION THAT CAN BE APPLIED TOPICALLY

摘要

The invention relates to a method for developing a liquid cosmetic composition to be applied to the skin as a foam and to a corresponding composition that can be foamed and that has at least one solvent, at least one active cosmetic ingredient, and at least one foaming agent. The foam volume and the foam stability are determined according to a standardized SITA measuring method. The foaming agent, the solvent, and the active cosmetic ingredient are varied in regard to the chemical type and/or concentration thereof until the foam thus produced by the SITA measuring method has a foam volume of at least 400 ml and such foam stability that after a dwell time of up to ten minutes the foam still has at least 50% of the foam volume that originally existed immediately after the foam was produced.
