The present invention is in the field of fabric cleaning compositions; in particular powder detergent compositions having foaming and cleaning characteristics in the main wash, yet significant foam reduction during rinse. Accordingly the present inventors have investigated ways of improving the defoaming ingredient such that the defoaming ingredient has improving foam-subsiding effects in the rinse stage. However they found that incorporating a monoester of glycerol of unsaturated fatty acids in a cleaning composition has adverse effects on the perfume impact of the cleaning composition. The inventors have found that the disadvantages of the prior art can be overcome, if a monoester of glycerol and unsaturated fatty acid is sorbed by a porous carrier material having a specific pore size and pH ranges. The inventive defoaming ingredient did not masked and/or altered the perfume delivery of the detergent composition.

A foamable, liquid cleaning composition comprising: i. 0.5 to 5 wt. % Calkoxylated anoionic surfactant having 1 to 30 moles of alkylene oxide; ii. 5 to 20 wt. % nonionic surfactants; iii. 0.1 to 10 wt. % water miscible glycol ether solvent; iv. 0.1 to 10 wt % water immiscible fatty acid ester solvent selected from the group consisting of methyl laurate, ethyl laurate, ethyl octanoate or mixtures thereof; v. 0.1 to 10 wt % of sequestrant selected from the group consisting of citric, adipic, succinic, maleic, glutaric acids, mixtures thereof or salts thereof; and vi. water, wherein the composition has a viscosity of less than 100 mPa&#xb7;s at 25&#xb0; C. and 20 s, wherein ratio of the sum of alkoxylated surfactant (i) and nonionic surfactant (ii) to the solvent is in a weight ratio ranging from 0.93:1 to 20:1, and wherein the pH of the composition ranges from 2.0 to 4.5. A cleaning system comprising a spraying device and a foamable liquid cleaning composition, said spraying device forming a foam with a density of less than 0.4 g/ml when ejected from the spray device through the spray head. A method of removing oily fatty stains from fabric. Use of the composition for the removal of oily fatty stains from fabric, said use comprising applying the liquid cleaning composition in the form of a foam onto the surface of the fabric.
