Claims
- 1. A foamable cosmetic or dermatological preparation comprising:
I. an emulsifier system comprising:
A. at least one emulsifier A selected from the group consisting of wholly neutralized, partially neutralized and unneutralized, branched and unbranched, saturated and unsaturated fatty acids having a chain length of 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 of from 10 to 40 carbon atoms and a degree of ethoxylation of from 5 to 100, and C. at least one coemulsifier C selected from the group consisting of saturated and unsaturated, branched and unbranched fatty alcohols having a chain length of from 10 to 40 carbon atoms; and II. up to 50% by weight—based on the total weight of the foamable preparation—of a lipid phase which comprises one or more lipids selected from the group consisting of silicone oils and silicone waxes.
- 2. The preparation as claimed in claim 1, wherein the lipid phase comprises up to 40% by weight—based on the total weight of the lipid phase—of additional lipids.
- 3. The preparation as claimed in claim 1, wherein the lipid phase comprises lipids having different polarities.
- 4. The preparation as claimed in claim 1, wherein the weight ratio of emulsifier A to emulsifier B to coemulsifier C (A:B:C) is a:b:c, where a, b and c, independently of one another, are from 1 to 5.
- 5. The preparation as claimed in claim 1, wherein the weight ratio of emulsifier A to emulsifier B to coemulsifier C (A:B:C) is a:b:c, where a, b and c, independently of one another, are from 1 to 3.
- 6. The preparation as claimed in claim 1, wherein the weight ratio of emulsifier A to emulsifier B to coemulsifier C (A:B:C) is 1:1:1.
- 7. The preparation as claimed in claim 1, wherein the total amount of the emulsifier A, the emulsifier B and the coemulsifier C is from 1 to 20% by weight, based on the total weight of the preparation.
- 8. The preparation as claimed in claim 1, wherein the emulsifier system further comprises at least one hydrophilic emulsifier.
- 9. The preparation as claimed in claim 8, wherein the hydrophilic emulsifier is selected from the group consisting of mono-, di- and tri-fatty acid esters of sorbitol.
- 10. The preparation as claimed in claim 8, wherein the total amount of the hydrophilic emulsifiers is less than 5% by weight, based on the total weight of the preparation.
- 11. The preparation as claimed in claim 1, further comprises at least one moisturizer.
- 12. The preparation as claimed in claim 1, wherein the emulsifier system consists essentially of the emulsifier A, the emulsifier B and the coemulsifier C.
- 13. A method of producing a foamable cosmetic or dermatological preparation, comprising combining a gaseous ingredient with a cosmetic or dermatological base comprising:
I. an emulsifier system comprising:
A. at least one emulsifier A selected from the group consisting of wholly neutralized, partially neutralized and unneutralized, branched and unbranched, saturated and unsaturated fatty acids having a chain length of 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 of from 10 to 40 carbon atoms and a degree of ethoxylation of from 5 to 100, and C. at least one coemulsifier C selected from the group consisting of saturated and unsaturated, branched and unbranched fatty alcohols having a chain length of from 10 to 40 carbon atoms; and II. up to 50% by weight—based on the total weight of the foamable preparation—of a lipid phase which comprises one or more lipids selected from the group consisting of silicone oils and silicone waxes.
- 14. The method as claimed in claim 13, wherein said gaseous ingredient and said cosmetic or dermatological bases are combined in a pressurized gas container.
- 15. The method as claimed in claim 14, wherein the gaseous ingredient is selected from the group consisting of linear and branched, halogenated and nonhalogenated hydrocarbons; carbon dioxide; oxygen; compressed air; nitrogen and dimethyl ether.
- 16. The method as claimed in claim 14, wherein the pressurized gas container is in the form of a cylindrical vessel.
- 17. The method as claimed in claim 14, wherein the pressurized gas container is formed of metal, shatterproof glass or plastic.
- 18. The method as claimed in claim 14, wherein the pressurized gas container is formed of protected, shattering glass or protected, shattering plastic.
- 19. The method as claimed in claim 13, further comprising the step of producing a foam from the foamable cosmetic or dermatological preparation.
- 20. The method as claimed in claim 19, wherein said foam is produced upon removal from a pressurized gas container.
