  • the alkylpolyglycosides are considered nonionic surfactant replacements, but, surprisingly, they achieve their best laundry results in combination with nonionic surfactants, especially those that are optimized for cleaning relatively hydrophobic surfaces.
  • the alkyl polyglycosides in these examples were derived from glucose. Similar results are obtained with the other alkyl glycosides described herein.
  • the unexpectedly poor showing of the alkylpolyglycoside with respect to this stain can be improved and/or synergistic improvement obtained by addition of the nonionic surfactant, depending upon the ratio used.
  • the mixed surfactant system of this invention provides equivalent or superior clay removal across a variety of fabric types as compared to more conventional anionic surfactants.
  • Test condition 450 ppm actives, 35°C water having 0.39 g mixed hardness and a mini-washer.
  • Composition of the invention C 12 - 13 alkylpolyethoxylate 3 /C 12-15 alkylpolyglycoside 2 - 3 at a ratio of 1:1.
