Zusammenfassung:PROBLEM TO BE SOLVED: To solve a problem that microemulsions exhibiting stability in a very narrow temperature range tend to become unstable under low temperature and high temperature conditions often encountered when shipping product or storing product in a warehouse.SOLUTION: The invention relates to microemulsion compositions containing water, a mixture of nonionic surfactants, and oil. The microemulsion provides for the removal of hydrophobic particularly oily soils from a variety of surfaces. The compositions can be used for cleaning hard surfaces and the laundry, hand washing, and car washing. Typical hydrophobic soils are oily soils derived from petroleum oils or natural fats and oils also containing a significant proportion of particulate soils such as carbon, common dirt and other non-water-soluble typically hydrophobic soil particulate. The microemulsion composition can include a separating medium such as an amphoteric surfactant for controlling the conditions under which the microemulsion is separated.
