Background
Removing stains from fabrics can be a challenge. If the stain is light and not greasy, washing the stained fabric with a detergent may produce satisfactory results. However, if the stain is heavy, washing with detergent does not generally remove the stain because the detergent ingredients are diluted in the wash and do not concentrate on the stain.
To successfully remove heavy stains, it is known in the art to apply a separate stain treatment, for example by spraying or jetting the stain treatment product directly onto the stain or scrubbing the stain using a wipe impregnated with the stain treatment product.

The viscosity of the composition was measured. The composition was sprayed from a spray bottle and the amount of spray (dose) was measured. Alternatively, the composition is sprayed onto the dyed fabric and the pretreated fabric is then washed after this treatment according to the procedures previously described herein. The results are summarized in table 8.
TABLE 8
Example 5
Liquid detergent compositions were prepared based on the formulations shown in table 9. Compositions 1 to 4 are examples of compositions according to the invention compared with composition a not according to the invention. As a control, a Vanish detergent (market sample) was used. The pH of all compositions of example 5 was in the range of 2.8 to 3.2.

The viscosity of the composition was measured.
These compositions were sprayed onto the dyed fabrics and the pretreated fabrics were then washed after this treatment according to the procedure described above. The amount (dose) of the composition delivered by one squeeze, as well as the density and mass of the foamed composition, were determined. The washing results obtained after pretreatment with these detergent compositions are summarized in table 10. The higher the SRI value, the more effective the composition for soil removal.
