Definitions

  • This invention relates to granulated laundry detergent compositions comprising a mixture of a nonionic surfactant with a cationic surfactant.
  • Cationic surfactants have been incorporated into detergent compositions, generally for the purpose of providing some fabric care benefit other than detergency, such as the provision of germicidal and sanitization benefits to washed surfaces, to soften fabrics and to control static.
  • cationic surfactants in detergent compositions is not without drawbacks.
  • the cationic surfactants complex with anionic detergents and whiteners and precipitate to eliminate the functional characteristics of the anionic and cationic materials.
  • Anionic whitener and brightener compounds are quenched or inhibited in effectiveness in the presence of cationic surfactants.
  • Cationic materials can also be detrimental to soil suspending. Many cationics attract soils to clean fabrics, thus compromising the cleaning ability of the compositions.
  • the surfactant system is substantially neutral with respect to the anionic and cationic material and preferably has an ionic excess of surfactant anions over surfactant cations. Otherwise, the cationic materials have been employed in a separate cycle so as to eliminate contact between the anionic materials and the cationic surfactants.
  • compositions comprising mixtures of anionic, cationic and nonionic surfactants are known in the art
  • laundry detergents comprising a mixture of nonionics and cationics alone are not commonly practical. This is due in no small measure to the extreme difficulty of formulating a properly balanced system.
  • the high level of nonionic and the excess cations with respect to anionic brightener contribute to a reduction in brightness and a greater tendency for soil to become redeposited upon the fabric.
  • anionics back to nonionic/cationic combinations to reduce the soil redeposition problem and to inhibit the negative effect of the cationic compound, vis-a-vis the brighteners.
  • this approach reduces detergency gains attributed to the cationic surfactant and, thus, results in a compromise between detergency and whitening.
  • nonionic and cationic mixtures as detergents has thus been limited to special detergent formulations such as degreasers and hard surface cleaners where (1) no whitener is included in the formulations and (2) the cleaning is not accomplished in a closed container, such as a washing machine, with suspended dirt which can be redeposited in the wash.
  • a granular laundry detergent comprises at least one nonionic surfactant, at least one anionic whitening agent, at least one builder and at least one cationic surfactant comprising a quaternary ammonium compound in which three of the substituents are lower alkyl or modified lower alkyl groups and the fourth substituent comprises a long chain alkyl or modified alkyl group joined to the nitrogen atom through an electronegative group which diminishes the aggressiveness of the cation towards the brightener and dirt redeposition.
  • the principal ingredients of the granular laundry detergent of the invention preferably include at least one nonionic surfactant, at least one anionic fluorescer, at least one builder and at least one etheramine-based cationic surfactant as described above. These principal ingredients may be included in the detergent compositions in the following ranges: Ingredient Range Preferred Range Best Mode Nonionic Surfactant 7-25 12-20 16 Cationic Surfactant 1-6 2-5 4 Builder 10-75 12.5-75 68 Fluorescer 0.05-1.5 0.25-1.0 0.4 Optionals to 100% to 100% to 100% to 100%

  • the electronegative group (E) z is a divalent radical directly attached to the nitrogen atom through a carbon-nitrogen linkage.
  • the E group can have the formula -(A(CH2) y ) z , wherein A is selected from the group consisting of and is preferably -O- and y is an integer in the range from 1 to 8, and is preferably 3, and z is as previously defined.
  • the electronegative group E is a divalent radical having the formula O-(CH2R6) m , wherein R6 is either hydrogen or preferably an alkylene group having from 1 to 4 carbon atoms, most prefera-bly 2 carbon atoms, and m is from 1 to 5, and is preferably 1.
  • R1 is a long chain alkyl group having from 8 to 20 carbon atoms which is directly attached through a carbon linkage to the electronegative group.
  • R1 can be an unbranched chain but is preferably a highly branched alkyl chain having no more than 4 carbon atoms in the longest unbranched group, with isotridecyl being the currently preferred long chain alkyl group.
  • R2, R3 and R4 can be the same or different and each is independently an alkyl group having from 1 to 4 carbon atoms, preferably methyl and/or H(OC n H2n) m wherein n is 1 to 4 and is preferably 2, and m is 1 to 10 and is preferably 1, with the proviso that at least one of R2, R3 and R4 is an alkyl group of 1 to 4 carbon atoms and is preferably methyl.
