| abstract |
A cleaning composition comprising from 80 to 98% by weight of water, from 1 to 25% percent by weight of an amphophilic solvent, from 0.1 to 10 percent by weight of a volatile hydrocarbon and from 0.1 to 1% by weight of cationic surfactant exhibits good cleaning performance and a visual indication of activity. The composition is on or adjacent to a phase boundary of its phase diagram and exhibits self-induced surface motility of the Marangoni type. |
