  • Example 14-A shows that cleaning medium with pH 5 does not result in effective cleaning, and that the fabric treatment composition, when used for cleaning rather than treating fabric, is not effective.
  • Examples 11-14 show that the cleaning efficacy improves with increase in pH. Cleaning in hard water
  • the reflectance after washing does not deteriorate strongly when hard water is used, unlike conventional detergent compositions where the performance deteriorates severely with hardness of water.
  • washing the same fabric monitors in 3 g/L SURF EXCEL®, a commercially available surfactant, AW reflectance drops to 58 at 48 FH from about 65 at 0 FH, a drop of 7 reflectance units.
