Definitions

  • the invention relates to solid detergent raw materials which are surface-coated with a polysiloxane and thus have a hydrophobic surface. It is thereby achieved that during the dissolving process of detergents which have been produced from such raw materials, the penetration is delayed, which leads to an improved washability of the detergent.
  • This publication discloses granular detergent additives, consisting of a granular, porous, water-soluble or water-dispersible carrier material and water-soluble or water-dispersible nonionic surfactants adsorbed thereon, in which the adsorbed non-ionic surfactant in a homogeneous mixture with a Hydrophobic substance having polar groups is present, the weight ratio of nonionic surfactant to hydrophobic substance being 99: 1 to 60:40.

  • the adhesion of water-swollen detergent preparations can be prevented by delayed dissolving of substances treated in this way.
  • the object of the invention is to provide hydrophobized detergent components. These hydrophobized detergent constituents surprisingly improve the washing-in behavior of the detergents produced from them. In addition, detergents made from such hydrophobic components show more favorable technical properties, in particular favorable storage behavior under moist and warm conditions.

These catalysts are expediently added in a separate process step after the addition of the polysiloxane or simultaneously with the reactive siloxane, if appropriate via separate nozzles.
  • the reactive polysiloxane according to the invention can be used quickly and safely at higher temperatures, it is preferred to incorporate the polysiloxane component at room temperature or, if appropriate, at the temperature at which the detergent raw material is present at the end of its manufacturing process .

Abstract

L'invention vise à améliorer les propriétés de dissolution d'agents de lavage ou de nettoyage. L'objectif est atteint essentiellement par la mise à disposition de matières brutes détergentes solides qui sont enrobées en surface d'un polysiloxane et présentent de ce fait une surface hydrophobe. Ce procédé permet lors de la dissolution de détergents fabriqués à partir de telles matières brutes, de différer la pénétration.
