  • An aqueous liquid laundry detergent was prepared of the following formulation:
  • the formulation was used to pretreat 10x10cm woven cotton cloth pieces; 1 ml of the formulation was placed in the centre of the cotton and rubbed in a circular motion. The cotton was then left lying on a flat non-porous surface for 24 hours and washing at a liquor to cloth ratio of 100:1 in 26° French Hard water at 20°C, in a plastic bottle placed on an orbital shaker (150rpm) for 1 hour. The cotton was removed and the colour of the cotton measured using a reflectometer. The colour was measured at the centre of the cloth, where the detergent was applied and also at the edge of the cloth, where the neat applied detergent did not reach. The colour was expressed as the CIE L * a * b * values and the difference in colour between the edge and the centre measured as Abstain:
  • the experiment was repeated with different levels of dye and level of uncharged alkoxylated polyarylphenol.
  • the polyarylphenol used was polyethylene glycol mono(2 6-tris(1-phenylethyl)phenyl) ether with different levels of ethoxylation (16 and 54EO).
  • the dye used was a phenazine dye of structure:.
  • the polyarylphenol reduced the neat contact staining of the dye, as seen by the reduction in Abstain value.
  • the 16EO compound was the more effective.
  • An aqueous liquid laundry detergent was prepared of the following formulation:
  • the formulation was used to pretreat 10x10cm woven cotton cloth pieces; 1 ml of the formulation was placed in the centre of the cotton and rubbed in a circular motion. The cotton was then left lying on a flat non-porous surface for 24 hours and washing at a liquor to cloth ratio of 100:1 in 26° French Hard water at 20°C, in a plastic bottle placed on an orbital shaker (150rpm) for 1 hour. The cotton was removed and the colour of the cotton measured using a reflectometer. The colour was measured at the centre of the cloth, where the detergent was applied and also at the edge of the cloth, where the neat applied detergent did not reach. The blue colour due to the dye was measured as the Reflectance at 590nm, as this is the maximum absorbance of the dye in the visible spectrum and is unaffected by fluorescence. The difference in colour between the edge and the centre measured as AR(590)stain:
  • AR(590)stain R(590)edge-R(590)stain
  • the larger AR(590) s tain value the greater the difference in colour between the centre and edge and the more visible the stain.
  • Three different polyalkyl/polyaryl phenol ethers were used: (a) 2,4,6 Tributyl phenol ether sulphate with 7 EO (b) 2,4,6 Tributyl phenol ether with 13 EO (c) 2,4,6 Tristryl phenol ether phosphate
  • the polyaryl/alkyl phenol reduced the neat contact staining of the dye, as seen by the reduction in AR(590) s tain value. This occurs for all 3 compounds: the alkoxylated polyalkyl phenol with and without a sulphonates group and for the alkoxylated polyaryl phenol with the sullphonate group.
  • the polyaryl phenol has best performance.
