  • the present invention relates to a cleaning composition, particularly, to a cleaning composition containing a Citrus essential oil component, and a method of removing stains from the surfaces of a substrate, especially a hard surface, using the composition.
  • a variety of household devices and office supplies such as tables, inner walls of kitchenwares such as microwave ovens and baking ovens, mirrors, windows, bathtubs, basins, wood furniture, floors and so on, have hard surfaces made of glass, ceramics, polyethylene, marble, wood, porcelain and the like.
  • the main reasons for cleaning these kinds of articles are (1) to remove stains, (2) to keep hard surfaces in good condition, and (3) to remove things harmful to human health and avoid creating environmental pollutants.
  • Surfactant is the most important component in a detergent. Because the surfactants employed in conventional detergents, such as linear alkyl benzene sulfonate, which is widely-used, need sodium tripolyphosphate to increase its resistance ability to had-water, there is raised a problem of eutrophication of the water system. Consequently, relevant laws have been set up since the 1970s by many countries to prohibit the overuse of phorsphor-containing compositions .
  • alkyl phenol is a decomposed component of alkyl phenol polyoxyethylene ether (APEO). It has low degradability in water and has the ability to diminish the reproductive organs of some birds and mammals or feminize mature male adult animals, resulting in the development of overies.
