The invention relates to self-foaming and/or foamed cosmetic or dermatological preparations containing I) an emulsifier system, which is comprised of: A) at least one emulsifier (A) selected from the group consisting of entirely, partially or non-neutralized, branched and/or unbranched, saturated and/or unsaturated fatty acids having a chain length ranging from 10 to 40 carbon atoms; B) at least one emulsifier (B), selected from the group consisting of polyethoxylated fatty acid esters having a chain length ranging from 10 to 40 carbon atoms and having a degree of ethoxylation ranging from 5 to 100, and; C) at least one co-emulsifier (C) selected from the group comprised of saturated and/or unsaturated, branched and/or unbranched fatty alcohols having a chain length ranging from 10 to 40 carbon atoms. The inventive preparations also contain: II) up to 30 wt. %, with regard to the total weight of the preparation, of a lipid phase; III) 1 to 90 vol. %, with regard to the total volume of the preparation, of at least one gas selected from the group consisting of air, oxygen, nitrogen, helium, argon, nitrous oxide (N2O) and carbon dioxide (CO2), and; IV) one or more substances selected from the group consisting of organic hydrocolloids. |
