Abstract
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 substrates. The compositions can be used for hard surface, laundry cleaning, hand washing, and car washing. Typical hydrophobic soils are oily based 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 splitting agent such as an amphoteric surfactant for controlling the conditions under which the microemulsion will split.
