- Many consumers have a desire to conserve resources and eliminate what they perceive as waste or unnecessary, without a noticeable or significant reduction in the performance of the product. Consequently, there is interest in the so called compact laundry product. However, even though compaction of laundry detergents may seem to be highly desirable it is problematic and difficult to deliver a compact product which is having good economics, provides good cleaning and is perceived by a consumer as being good value. By way of example, the reduction or increase of the components of a laundry product, such as builders, fillers, surfactants etc, to arrive at a compact formula means that the relative amounts of these components is different to the one present in the non-compact product. With less solid detergent composition introduced into the aqueous laundering composition, the compact composition have less ability to clean well, and less ability to mitigate the negative effect of calcium ions on surfactant performance.
- This means that, to produce a compact product which has comparable performance to a non-compact product, significant time and effort will be involved.
- Consequently, the need remains for a compact detergent that is comparable in performance to existing non-compact laundry detergent.
- In one embodiment of the present invention, the invention concerns a method of laundering soiled fabrics in an automatic washing machine, which method comprises the steps of:

- Step a) and b) may be executed in any order and the soiled fabrics may be contacted to the water prior to, or after, or simultaneous with, contacting the solid detergent composition with water.
- The inventors have found that detergent compositions having the dissolution of the invention and comprising a surfactant system having the τ2 of the invention were particularly suitable in compact compositions. The method of laundering of the invention is providing good cleaning performance while using a low concentration of detergent composition in the aqueous laundering solution.

The alcohol insoluble portion of the residue is rinsed into the filter paper with warm (40° C.) ethanol and washed with 3×20 mL portions of warm ethanol. The combined filtrates are evaporated on a steam bath in a fume hood, taking care to guard against loss of sample by excessive foaming or bumping. When the last few ml of solvent remain in the beaker, it is allowed to cool and 10 ml of acetone are added. The residue is evaporated to dryness taking care to guard against loss of sample by excessive foaming or bumping. The beaker is allowed to cool in a desiccator and weighed.
