| abstract |
The present invention is a self-foaming, foamed, post-foaming or foamable cosmetic and dermatological preparation comprising I) an emulsifier system comprising A) at least one emulsifier selected from the group of fully-, partially- and non-neutralized, branched and unbranched, saturated and unsaturated fatty acids having a chain length of 1-40 carbon atoms, B) at least one emulsifier selected from the group of polyethoxylated fatty acid esters having a chain length of 10 to 40 carbon atoms and a degree of ethoxylation of 5 to 100, and C) at least one coemusifier selected from the group of saturated and unsaturated, branched and unbranched fatty alcohols having a chain length of 10 to 40 carbon atoms, and II) up to 30% by weight—based on the total weight of the preparation—of a lipid phase comprising a) one or several lipids selected from the group consisting of silicone oils and silicon waxes and b) one or several lipids from the group of nonpolar lipids having a polarity ≧30 mN/m, the ratio of (a) to (b) ranging from 1:3-3:1. The present invention also includes a method of preparing foam comprising combining the cosmetic or dermatological preparation with at least one filler material gas or propellant are releasing the preparation and the filler material gas or propellant from a pressurized gas container. |
