  • the present invention relates to cleaning agents, preferably as powders, pastes or as an aqueous formulation, based on a water-soluble polymeric polycarboxylate as a dispersant for cleaning sooty surfaces.
  • Carbon black is a black powder consisting of 80-99.5% carbon, which is made up of tiny, spherical particles that grow together to form chain-like aggregates.
  • the specific surface area is about 10-1000 m 2 / g.
  • Soot is an important technical product resulting from the incomplete combustion or pyrolysis of hydrocarbons. The most important manufacturing process is the Furnace process. In this process, aromatic-rich soot oils (coal tar and petroleum products) are injected into a gas flame of 1200-1800 ° C.
  • Carbon black is more than 90% used as a filler in the rubber industry and also as a pigment for printing inks, inks, paints and in the electrical industry. Carbon black also occurs as the most undesirable product in uncontrolled combustion processes and then usually contains adsorbed on its surface oily components and pyrolysis. This soot has shown in animal experiments a potential for the production of cancer, reinforced by the frequently present polycyclic aromatics.

  • nonionic cosurfactants examples include the adducts of 13 to 40 moles of ethylene oxide with C 8 -C 22 -alcohols or with from 1 to 40 moles of ethylene oxide with C 8 -C 22 -alkylphenols and the alkylpolyglycosides.
  • the nonionic cosurfactants can be used in an amount of up to 8% by weight, in particular up to 6% by weight and more preferably up to 2% by weight, based on the finished carbon black cleaner.
  • the soot cleaners according to the invention can be present as so-called normal products, as concentrates and as pastes, it being known to the person skilled in the art that the transitions between these products are fluid.
  • Normal products are usually liquid and are solutions of their ingredients.
  • the so-called concentrates are solutions or emulsions of the ingredients and have a liquid to viscous consistency.
