Definitions

  • the present invention relates to detergent compositions, preferably liquid detergents, containing an anionic synthetic surfactant, a cosurfactant selected from the group consisting of certain quaternary ammonium, diquaternary ammonium, amine and diamine surfactants, and a fatty acid.
  • the compositions herein have a molar ratio of the anionic synthetic surfactant to the cosurfactant of at least 1 and are formulated to provide an initial pH of from about 6.0 to about 8.5 at a concentration of from about 0.1 % to about 2% by weight in water at 20°C.
  • the compositions provide both superior greasy/oily soil removal and good builder/pH sensitive soil removal at the near-neutral wash pH.
  • the compositions have a pH of from about 6.0 to 7.5.
  • the present invention encompasses detergent compositions comprising:
  • the detergent compositions herein contain an anionic synthetic surfactant, a cosurfactant selected from certain quaternary ammonium diquaternary ammonium, amine and diamine surfactants, and a fatty acid material.
  • the compositions can be in any form, including granules, liquids, tablets or pastes. However, liquid compositions are highly preferred since the compositions herein are especially effective when applied directly to soils and stains in a pretreatment step.
  • compositions herein must have a molar ratio of the anionic synthetic surfactant to the cosurfactant of at least one, preferably from about 2:1 to about 20:1, and are formulated to provide an initial pH of from about 6.0 to about 8.5 at a concentration of from about 0.1 % to about 2% by weight in water at 20°C. It has been found that the addition of the cosurfactant to the fatty acid containing detergents herein provides important greasy/oily soil removal benefits only at the near-neutral wash pH.
  • the wash pH is preferably from about 7.0 to about 8.5, more preferably from about 7.5 to about 8.0.
  • the cosurfactant and anionic surfactant herein form complexes which enhance packing of the surfactants at the oil/water interface, thereby lowering interfacial tension and improving detergency.
  • the amine and diamine surfactants would be at least partially protonated at the near-neutral pH and thus can form charges species capable of complexing with the anionic surfactant).
  • the fatty acid component exists in a chemical form which is optimal for effective detergency. At too low a pH, the non-dissociated form of the acid is ineffective. It is also believed that the higher pH's (i.e., above about 8.5) affect the interaction of the fatty acid with the cosurfactant and water hardness and result in the formation of undesirable species at the oil/water interface which reduce detergency performance.
  • the detergent compositions herein contain from about 2% to about 60% by weight of an anionic synthetic surfactant, or mixtures thereof.
  • the anionic surfactant preferably represents from about 5% to about 40%, and more preferably from about 10% to about 20%, by weight of the detergent composition.

  • Other useful anionic surfactants herein include the water-soluble salts of esters of a-sulfonated fatty acids containing from about 6 to 20 carbon atoms in the fatty acid group and from about 1 to 10 carbon atoms in the ester group; water-soluble salts of 2 - acyloxy - alkane - 1 - sulfonic acids containing from about 2 to 9 carbon atoms in the acyl group and from about 9 to about 23 carbon atoms in the alkane moiety; water-soluble salts of olefin sulfonates containing from about 12 to 24 carbon atoms; and ⁇ -alkyloxy alkane sulfonates containing from about 1 to 3 carbon atoms in the alkyl group and from about 8 to 20 carbon atoms in the alkane moiety.
