ABSTRACT:
The invention relates to a cleaning composition suitable for manually cleaning substrates. The composition comprises at least two immiscible liquid phases having one liquid-liquid interface with an interfacial tension of more than 5 mN/m, the difference in density between the two liquid phases being not more than 0.2 g/cc. After agitation, the composition is applied to the substrate to be cleaned, and subsequently friction is applied to the substrate. The composition provides for the required stability after agitation, and gives good detergency, particularly as regards particulate soil.
