Definitions

  • This invention relates to a light duty liquid cleaning composition which imparts mildness to the skin and is designed in particular for dishware and which is effective in removing grease soil and in leaving unrinsed surfaces with a shiny appearance.
  • all-purpose liquid detergents have become widely accepted for cleaning hard surfaces, e.g., painted woodwork and panels, tiled walls, wash bowls, bathtubs, linoleum or tile floors, washable wall paper, etc.
  • Such all-purpose liquids comprise clear and opaque aqueous mixtures of water-soluble synthetic organic detergents and water-soluble detergent builder salts.
  • use of water-soluble inorganic phosphate builder salts was favored in the prior art all-purpose liquids.
  • such early phosphate-containing compositions are described in U.S. Patent Nos. 2,560,839; 3,234,138; 3,350,319; and British Patent No.
  • an o/w microemulsion is a spontaneously forming colloidal dispersion of "oil" phase particles having a particle size in the range of about 25 to about 800 A in a continuous aqueous phase.
  • microemulsions are transparent to light and are clear and usually highly stable against phase separation.
  • Patent disclosures relating to use of grease-removal solvents in o/w microemulsions include, for example, European Patent Applications EP 0137615 and EP 0137616 - Herbots et al; European Patent Application EP 0160762 - Johnston et al; and U.S. Patent No. 4,561 ,991 - Herbots et al. Each of these patent disclosures also teaches using at least 5% by weight of grease-removal solvent.

  • Nonionic surfactants are in general chemically inert and stable toward pH change and are therefore well suited for mixing and formulation with other materials. The superior performance of nonionic surfactants on the removal of oily soil is well recognized. Nonionic surfactants are also known to be mild to human skin. However, as a class, nonionic surfactants are known to be low or moderate foamers. Consequently, for detergents which require copious and stable foam, the application of nonionic surfactants is Iimited. There have been substantial interest and efforts to develop a high foaming detergent with substantial amounts of nonionic surfactants. Yet, little has been achieved.
