COSMETIC FOAM MADE FROM AN EMULSION CONTAINING GLYCERINE AND ALCOHOL

Abstract

The invention relates to a cosmetic foam made from a) an O/W emulsion containing glycerine and b) mono- and/or polyvalent alcohols with a carbon chain length of less than 12 C-atoms and c) a gas or gas mixture of propane, n-butane and/or isobutane, foaming the emulsion, which emulsion is fre of polyethylene glycol derivatives (PEG derivatives).

Claims

1.-13. (canceled)

15. The foam of claim 14, wherein (i) comprises from 3% to 20% by weight of glycerol, based on a total weight of (i).

16. The foam of claim 14, wherein (i) comprises a total concentration of (b) of from 0.5% to 10% by weight, based on a total weight of (i).

17. The foam of claim 15, wherein (i) comprises a total concentration of (b) of from 0.5% to 10% by weight, based on the total weight of (i).

18. The foam of claim 14, wherein (b) comprises one or more of ethanol, phenoxyethanol, 1,2-pentanediol, 1,2-hexanediol, 1,2-octanediol, 2-methyl-1,3-propanediol, 1,2-decanediol, ethylhexylglycerol, benzyl alcohol, phenethyl alcohol.

19. The foam of claim 14, wherein (b) comprises ethanol.

20. The foam of claim 14, wherein (b) comprises phenoxyethanol.

21. The foam of claim 14, wherein (b) comprises ethylhexylglycerol.

22. The foam of claim 14, wherein (b) comprises 2-methyl-1,3-propanediol.

23. The foam of claim 14, wherein (b) comprises at least one of 1,2-pentanediol, 1,2-hexanediol, 1,2-octanediol.

24. The foam of claim 14, wherein (i) is free of soaps and surfactants having an HLB value of greater than 12.

25. The foam of claim 14, wherein the foam comprises from 90% to 96% by weight of (i) and from 4% to 10% by weight of (ii).

26. The foam of claim 14, wherein (i) is free of parabens, isothiazolinones, 3-iodopropargyl N-butylcarbamate (IPBC), and halogen-containing compounds.

27. The foam of claim 14, wherein a lipid phase of (i) comprises at least one of behenyl alcohol, almond oil, cocoa butter, shea butter.

28. The foam of claim 14, wherein (i) comprises from 7% to 25% by weight of lipid phase, based on a total weight of (i).

29. The foam of claim 14, wherein (i) comprises one or more emulsifiers selected from polyglycerol esters, cetearyl glycoside, sodium stearoyl glutamate, glyceryl stearate citrate, cetyl phosphate, stearic acid salts, a combination of sodium cetearyl sulfate and glyceryl stearate SE.

30. The foam of claim 14, wherein (i) comprises a total of from 0.1% to 8% by weight of one or more emulsifiers, based on a total weight of (i).

31. The foam of claim 14, wherein the foam is present in an aerosol can with release valve.

32. An aerosol can with release valve, wherein the can comprises the foam of claim 14.

33. A method of applying the foam of claim 31 to skin, wherein the method comprises shaking the can and subsequently withdrawing the foam via the release valve and applying it to the skin.
