  • the cotton, poly cotton and polyester fabric swatches (commercially available from WFK, Germany) were soaked in this dispersion for 30 minutes, and dried in air overnight. The swatches were 10x10 cm.
  • a composite soil was prepared by sonicating a mixture containing 100 ml triolein, 4 mg carbon soot and 4 mg iron oxide for 1 hour. A homogeneous soil dispersion was obtained.
  • the fabric swatches were soiled with composite soil and aged for a day at room temperature (ca 24°C). The swatches were then washed in surf XL (ex Unilever) by hand wash procedure.
  • compositions according to the invention are compared to comparative compositions.
  • Polymer formulations (as specified in the table below) were prepared according to the method of example 1 .
  • the dispersion was checked for lump formation and uniformity.
  • Desized cotton, polycotton and polyester fabric swatches of 10 x 10 cm were pretreated by soaking into the polymer composition (dispersion) at a liquid to cloth ratio of 5:1 and soaked for 20 minutes.
  • the fabrics used had a mass of 1 .5 g each (i.e. for 100 cm 2 ), resulting in a total of 18.75 g of total polymer per cm 2 of fabric (one side), in the examples where polymer was present. Fabrics were taken out, squeezed out the excess liquor and dried in air.
  • Fabrics were soiled with 0.3 ml of composite soil dispersion (see example 2) applied to about 20 cm 2 area and kept for ageing for 16 hours.
  • the fabric swatches were than washed by hand wash, in 1 .5 g/l Surf XL wash liquor, at a wash liquor to cloth ratio of 5:1 .
  • the fabric swatches were soaked in the liquor for 30 minutes.
  • the soaked fabrics were washed by a handwash protocol by brushing 5 times on both side of the fabrics. After brushing the fabrics were rinsed three times l o with clean water and dried in air.
  • the reflectance of the soil region was measured before and after washing using a reflectometer; the cleaning performance is indicated as the difference ("Delta R") between the reflectance at 460 nm before and after washing, as is a commonly known procedure in the art.
  • Composition E 3 g/l Surf XL (ex Unilever).
  • Composition F 1 .5 g/l Surf XL (ex Unilever).
  • 3 g/l detergent product is representative for normal hand wash and horizontal axis machine wash. 1 .5 g/l is included because the fabrics that are pre-treated with the compositions of the invention are washed with only half of the standard main wash dosage.
  • compositions G - O Comparative compositions (compositions G - O)
  • Examples 5-17 show compositions according to the invention. Unless otherwise indicated the concentrations in which the ingredients were used were:
  • PAA poly acrylic acid; Mw 450,000 D, ex Sigma-Aldrich
  • PEO poly ethylene oxide; Mw 100,000 D, ex Sigma-Aldrich
  • NaCI 0.75 g/l
  • Perfume 0.045
  • Kaolin 0.25 g/l
  • Citric acid 0.2 g/l
  • Adipic acid 0.4 g/l
  • Phthalic anhydride 0.4 g/l
  • Soda 0.15 g/l in the pre-treating wash liquor.
  • NB PAA is polyacrylic acid
  • Soda is Na 2 C0 3
  • PEO is poly ethylene oxide
  • NaCI is sodium chloride
