Abstract

A packaged personal cleansing product comprising: (i) a foaming composition, wherein the foaming composition comprises less than 25% by weight, preferably less than 15% by weight, of water, at least 18% by weight of surfactant, wherein the surfactant comprises an anionic surfactant selected from alkyl glyceryl ether sulfonates, methyl acyl taurates, fatty acyl glycinates, N-acyl glutamates, acyl isethionates, acyl ethoxylated isethionates, acyl short chain branched isethionates, paraffin sulphonates, alpha-olefin sulphonates, fatty amide ethoxylated carboxylates, alkyl sulfosuccinates, alkyl ethoxysulphosuccinates, alpha-sulfonated fatty acids, their salts and/or their esters, alkyl phosphate esters, ethoxylated alkyl phosphate esters, acyl sarcosinates, and mixtures thereof, (ii) propellant gas; and (iii) a container for (i) and (ii); characterised in that the propellant gas comprises carbon dioxide, nitrous oxides, or mixtures thereof and that the viscosity of the foaming composition, measured at 20° C. and 1 atmosphere, using a Brookfield viscometer, No.2 Spindle at 60 rpm, is less than 700 mPa.s. The packaged personal cleansing product of the present invention provides improvided lathering, mildness, improved deposition of skin/hair care ingredients onto the skin and improved perfume delivery and residuality.

Claims

1. A packaged personal cleansing product comprising:

(i) a foaming composition, wherein the foaming composition comprises less than 25% by weight, preferably less than 15% by weight, of water, at least 18% by weight of surfactant, wherein the surfactant comprises an anionic surfactant selected from alkyl glyceryl ether sulfonates, methyl acyl taurates, fatty acyl glycinates, N-acyl glutamates, acyl isethionates, acyl ethoxylated isethionates, acyl short chain branched isethionates, paraffin sulphonates, alpha-olefin sulphonates, fatty amide ethoxylated carboxylates, alkyl sulfosuccinates, alkyl ethoxysulphosuccinates, alpha-sulfonated fatty acids, their salts and/or their esters, alkyl phosphate esters, ethoxylated alkyl phosphate esters, acyl sarcosinates, and mixtures thereof;

(ii) propellant gas; and

(iii) a container for (i) and (ii);

characterised in that the propellant gas comprises carbon dioxide, nitrous oxides, or mixtures thereof and that the viscosity of the foaming composition, measured at 20°

C. and 1 atmosphere, using a Brookfield viscometer, No.2 Spindle at 60 rpm, is less than 700 mPa.s.

2. A packaged product according to claim 1 wherein the foaming composition further comprises a viscosity reducing, organic solvent.

3. A packaged product according to claim 2 wherein the viscosity reducing, organic solvent is selected from the group consisting of polyethylene glycol, short chain alkyl ethoxylates, glycerol, Carbowax, butyl diglycerol ether, and mixtures thereof.

4. A packaged product according to any of claims 1 to 3 wherein the propellant gas is selected from carbon dioxide, nitrous oxides, and mixtures thereof.

5. A packaged product according to any of claims 1 to 4 wherein the propellant gas further comprises an organic propellant.

6. A packaged product according to claim 5 wherein the propellant gas further comprises propane, butane, pentane, hexane, or mixtures thereof.

7. A packaged product according to any of claims 1 to 6 wherein the surfactant comprises a nonionic surfactant selected from C12-C18 fatty acid mono- and di-ethanolamides, and ethoxylated derivatives thereof, alkyl polyglucosides, ethoxylated fatty alcohols, sucrose polyester surfactants and polyhydroxy fatty acid amide surfactants.

8. A packaged product according to any of claims 1 to 7 wherein the surfactant comprises an amphoteric surfactant selected from:
