Abstract

The present invention relates to the use of ortho-substituted ethoxylated Al or Zn-phthalocyanine compounds as photobleach agents for the removal of stains and soil on textile materials, particularly in laundry detergents. A further aspect of the invention is a process for removing stains and soil from textile materials using the Al or Zn-phthalocyanine compounds in a washing process and exposing the washed textile material to actinic radiation. Still further aspects are detergent and granule formulations containing ortho-substituted ethoxylated Al or Zn-phthalocyanine compounds and also new orthosubstituted ethoxylated Zn-phthalocyanine compounds as such.
