Definitions

  • the present invention relates to dishwashing detergent compositions containing detergent surfactants and high levels of long chain amine oxides for low to moderate sudsing compositions with improved grease emulsification.
  • Dishwashing detergent compositions are well known in the art. However, the removal of greasy food residues from dishware in dishwashing operations has become a particular challenge to the formulator.
  • Modern dishwashing compositions are, in the main, formulated as aqueous liquids; accordingly, water- stable ingredients must be used.
  • hand dishwashing composition such compositions come into prolonged contact with skin; therefore, they must be mild. Yet, mildness is difficult to achieve in an effective dishwashing product, since products which remove grease from dishware may also tend to remove the natural skin oils from the user's hands.

  • the invention herein is based on the unexpected discovery that use of long chain amine oxides at particular levels, substantially enhance the grease and oil removal properties of detergent compositions and inhibit sudsing, especially, but not limited to, anionic surfactants. While not intending to be limited by theory, it appears that inclusion of such amine oxides into such compositions substantially enhances their ability to rapidly lower the interfacial tension of aqueous washing liquors with greasy and oil soils. This substantial reduction of interfacial tension leads to what might be termed "spontaneous emulsification" of greasy and oil soils, thereby speeding their removal from soiled surfaces and inhibiting the redeposition of the soils onto substrates.

  • Calcium or Magnesium Ions The presence of calcium and/or magnesium (divalent) ions improves the cleaning of greasy soils for various compositions, i.e. compositions containing alkyl ethoxy carboxylates and/or polyhydroxy fatty acid amide. This is especially true when the compositions are used in softened water that contains few divalent ions. It is believed that calcium and/or magnesium ions increase the packing of the surfactants at the oil/water interface, thereby reducing interfacial tension and improving grease cleaning.
  • compositions of the invention hereof containing magnesium and/or calcium ions exhibit good grease removal, manifest mildness to the skin, and provide good storage stability.

  • An example of a commercially available alkylpolyethoxypoly- carboxylate which can be employed in the present invention is POLY-TERGENT C, Olin Corporation, Cheshire, CT.
  • the alkylpolyethoxypolycarboxylate surfactant is selected on the basis of its degree of hydrophilicity. A balance of carboxylation and ethoxylation is required in the alkylpolyethoxypolycarboxylate in order to achieve maximum chelating benefits without affecting the cleaning benefits which is associated with the divalent ions or the sudsing of the liquid or gel dishwashing detergent compositions.
  • the number of carboxylate groups dictates the chelating ability, too much carboxylation will result in too strong a chelator and prevent cleaning by the divalent ions.
  • a high degree of ethoxylation is desired for mildness and solubility; however, too high a level will affect sudsing. Therefore, an alkylpolyethoxypolycarboxylate with a modest degree of ethoxylation and minimal carboxylation is desirable.
