  • the alkyl groups are preferably linear or branched, most preferably linear.
  • indefinite article “a” or “an” and its corresponding definite article “the” as used herein means at least one, or one or more, unless specified otherwise.
  • Dye weights refer to the sodium or chloride salts unless otherwise stated.
  • a powder laundry detergent was prepared of the following formulation: Ingredient Weight% Linear alkyl benzene sulfonate 14.5 Sodium carbonate 20.0 Sodium sulphate 50.0 Sodium silicate 6.0 zeolite 2.5 Salt speckle granules (blue and red) 1.8 perfume 0.3 Sodium carboxymethylcellulose 0.1 Sokalan CP5 (ex BASF) 0.1 Minors (including fluorescer shading dye with CAS-No 72749-80-5 and CAS-No 81-42-5 ) and moisture to 100%
  • 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 60 minute wash was conducted in 800ml of 26° French Hard water at 35°C, with 1.5g/L of the formulation. To simulate oily soil (7.4 g) of an SBL2004 soil strip (ex Warwick Equest) was added to the wash liquor.
  • the combination of lipase and alkoxylated polyarylphenol with 10, 15 and 54EO to the formulation increases the stain removal as seen by higher ⁇ L* values compared to the reference control values.
  • the combination of lipase and alkoxylated polyarylphenol with 10EO, and 16EO gives a greater increase in stain removal than expected from combination of the effects of the single components.
