Definitions

  • the present invention relates to water-soluble granules of phthalocyanine compounds, a process for their preparation and their use in detergent preparations.
  • Water-soluble phthalocyanine dyes especially zinc and aluminum phthalocyanine sulfonates, are often used as photoactivators in detergent preparations. Because of the slow dissolution rate of these photoactivators, step into water often problems, especially if the wash liquor is insufficiently mixed, because the colored photoactivators stain the laundry.
