Abstract
Stable microemulsion cleaning compositions are described which, in the absence of opacifying component, appear clear to the eye, and which are especialy useful for cleaning surfaces having oily or greasy soils thereon, which comprise synthetic organic detergent, water, co-surfactant of a described type, and perfume (or equivalent hydrocarbon). The detergent composition may be concentrated and may be employed as is, or it may be in dilution with water, in the form of a similarly clear and stable microemulsion. In process aspects of the invention both the concentrated and the diluted compositions may be employed to remove oily and greasy stains from substrates, such as normally shiny bathroom fixture and floor and wall surfaces, including tiles, by a "spray and wipe" process, which leaves the surface shiny, with minimal or no rinsing needed. When the invented compositions are acidic they are also useful for removing lime scale and soap scum from hard surfaces. Also described are processes for manufacturing the invented compositions.
