  • EP-A-293,040 discloses high pH, aqueous liquid detergent compositions comprising anionics, at most partially dissolved bleach material and water-miscible organic solvent. The document teaches the use of high water/solvent levels as well as relatively high organic solvent levels and relatively low water levels to stabilise the bleach material.
  • a problem of the formulations as disclosed in these patent application is the relatively low level of active materials. These low active levels generate the need for high dosages of liquid detergent materials to be used per washing cycle.
