  • Preferred reactive anthraquinone dyes are: Reactive blue 1; Reactive blue 2; Reactive blue 4; Reactive blue 5; Reactive blue 6; Reactive blue 12; Reactive blue 16; reactive blue 19; Reactive blue 24 ; Reactive blue 27; Reactive blue 29; Reactive blue 36; Reactive blue 44; Reactive blue 46 ; Reactive blue 47; reactive blue 49; Reactive blue 50; Reactive blue 53; Reactive blue 55; Reactive blue 61; Reactive blue 66; Reactive blue 68; Reactive blue 69; Reactive blue 74; Reactive blue 86; Reactive blue 93; Reactive blue 94; Reactive blue101; Reactive blue103; Reactive blue114; Reactive blue117; Reactive blue125; Reactive blue141; Reactive blue142; Reactive blue 145; Reactive blue 149; Reactive blue 155; Reactive blue 164; Reactive blue 166; Reactive blue 177; Reactive blue 181; Reactive blue 185; Reactive blue 188; Reactive blue 189; Reactive
  • the dyes are listed according to Colour Index (Society of Dyers and Colourists/American Association of Textile Chemists and Colorists ) classification.
  • the formulation was used to wash eight 5x5cm EMPA 117 stain monitor (blood/milk/ink stain on polycotton) in a tergotometer set at 200rpm. A 20 minute wash was conducted in 800ml of 26° French Hard water at 35°C, with 2.3g/L of the formulation. To simulate oily soil (12.5 g) of an SBL2004 soil strip (ex Warwick Equest) was added to the wash liquor.
  • subtilisin serine protease (EC no. 232-752-2) to the wash liquor (Evity® 16L ex Novozymes).
  • the enzyme was added to give 0.009 wt% pure active protein to the formulation.
  • protease and alkyl ether carboxylic acid increases the stain removal as seen by higher L* values.
  • the increase is larger for the 5EO, 8EO and largest for the 10EO.
  • the combination of protease and alkyl ether carboxylic acid with 5EO, 8EO and 10EO gives a greater increase in stain removal than expected from combination of the effects of the single components.
  • For 5EO/protease an L* value of 56.08 is expected and 58.04 obtained.
  • 8EO/protease a value of 55.76 is expected and 58.54 obtained.
  • the increase was greatest for 10EO/protease where a value of 57.28 is expected and 60.90 obtained.
