  • radical initiators are used in the present examples. They are available commercially under the trade marks set out below from Ciba Specialty Chemicals.
  • Cloths heavily stained with stains set out in Table 1 were obtained from a commercial supplier (Equest, stains aged for three days then sealed). The stained cloths were then treated with solutions of ethanol containing various radical photoinitiators and then placed in an Atlas S3000 Weatherometer WOM (trade mark) for 12 minutes (at a power level of 0.35 w/m2 at 340 nm). The results in the change in reflectance at 460 nm (R(460 nm)) measured using a Spectraflash SF60 (trade mark) reflectometer are set out in table 4.
  • the radical initiators lead to an increase in reflectance at 460 nm for a variety of stains. That is, the radical initiators effectively bleach the stains from the fabric.
  • Example 1 The method of Example 1 was repeated, using treatment 1, 2 and 4 except that the quantity of Irgacure 819 (trade mark) in the ethanol was varied. The results are shown in Table 2.

  • Example 4 1 gram of this base powder was intimately mixed with 0.024 g of Irgacure 819. The final product contains 2.3% by weight of Irgacure 819.
  • Example 5 1 gram of base powder was intimately mixed with 0.024 g of Irgacure 369. The final product thus contains 2.3% by weight Irgacure 369.
  • the mixture of base powder and radical photoinitiator was dissolved in 400 grams water at 40°C.
  • Three lots of cotton cloth were prepared. Each contained sheets weighing 16.1 grams in total and brushed cotton weighing 10 grams in total. All cloth was white. For each lot, both types of cloth were cut into four pieces. The lots were then washed in the solution prepared above for 5 minutes. One piece of cotton sheeting and one piece of brushed cotton was removed and dried. The wash solution was discarded and the cotton rinsed in 600 grams of cold water. One piece of the cotton sheeting and brushed cotton was removed and dried. The first rinse solution was then discarded. A second rinse was then conducted with a further 600 grams of water. Again, one piece of cotton sheeting and one piece of brushed cotton were removed.
  • the pieces of cotton sheeting and brushed cotton removed at each step were tested to see how much initiator had deposited onto the cloth. This was measured by measuring the reflectance of the dried cloths at 320 nm using a Spectraflash SF60 (trade mark) reflectance spectrometer.
  • the reflectance of the cloth washed with powder compositions containing radical initiator is lower than the control composition which contains no radical initiator. This is because the Irgacure radical initiator absorbs strongly at 320 nm reducing the reflectance. The changes in reflectance measured were significantly above the noise level for this type of measurement and confirm the deposition of the initiators.
  • Examples 4 and 5 demonstrate that radical photoinitiators may be deposited onto fabric from a laundry composition.
  • the following rinse conditioner formulation was prepared:
  • Example 6 The procedure of Example 6 was repeated except that Irgacure 819 (trade mark) was padded from ethanol onto stained cloths at 0.1% on-weight-fabric. For each stain, separate samples were taken and then wetted with buffer solution of varying pH. The resulting cloths were irradiated for 12 minutes in the Atlas S3000 (trade mark) Weatherometer. The variation in average reflectance at 460 nm after treatment is shown in the table. The average reflectance at 460 nm for the four treatments was 46.5. It can be seen that the radical photoinitiators give a substantial improvement in reflectance over a wide range of pH. pH 3 5 7 9 average R 460 77.0 78.8 76.5 68.4
  • Liquid detergents were created from, Coco5E0 (ex Clariant - a non ionic surfactant), SDS (sodium dodecyl sulphate - an anionic surfactant), CTAC (cetyl trimethyl ammonium chloride -a cationic surfactant), Arquad 2HT (ex Akzo Nobel - a cationic surfactant), with 0.1% Lucerin TPO-L and 10% ethanol on weight of formulation; the remainder was water.
  • Formulation L1 of example 10 was made using Irgacure 819 instead of TPO-L. Good stain removal benefits above control were obtained.
  • a detergent composition was created containing 15.3% of an anionic surfactant, 10% ethanol, 0.1% Lucerin TPO-L, remainder water.
  • the anionic surfactants were LAS, and SDS.
  • Persil liquid was purchased in Ireland and 0.01% on weight Lucerin TPO-L added to the product. On washing, rinsing and irradiating cloth stained with ⁇ -carotene, much greater stain removal was found when the initiator was present.
  • the initiators benzoin, dimethoxyphenylacetophenone, benzoin methyl ether, and benzoin ethyl ether (ex Aldrich) were seperately applied from ethanol to cotton cloth stained with ⁇ -carotene. All bleached the stain. As expected the initiators with higher logP value gave less dye damage.
