Silicone glycols of a particular molecular weight range are effective in preventing streaking of cleaning compositions which contain liquid, non-ionic surfactants, particularly on glass and ceramic surfaces. The invention provides a cleaning composition comprising: (a) 0.05-10 %wt of a liquid, alcohol alkoxylate, non-ionic surfactant, and (b) at least 5 % on total surfactant of a silicone glycol having a molecular weight in the range >3,000-40,000. It is believed that the synergistic interaction of the selected non-ionic surfactant and the selected silicone glycol polymer maintains a low surface tension in the drying film and prevents roll-up of droplets to form streaks. A second aspect of the invention provides a method of cleaning a glass or ceramic surface which comprises the step of treating the surface with a composition as described above. |
