  • ester quats with improved solubility or dispersibility in cold water are the skillful selection of the fatty acid component and the use of emulsifiers or dispersants (e.g. fatty alcohols or nonionic surfactants) as solvents instead of isopropyl alcohol in the alkoxylation and are the subject of previously unpublished patent applications .
  • emulsifiers or dispersants e.g. fatty alcohols or nonionic surfactants
  • nitrogen-containing compounds produced by the methods of the prior art cannot be dissolved or dispersed, or can only be insufficiently dispersed.

  • Another problem is that even those prior art products that have satisfactory solubility or dispersibility often lose irreversibly when stored in air.
  • the object of the invention was therefore to provide a new process for the preparation of anhydrous nitrogen-containing compounds with improved cold water solubility or dispersibility and storage stability, which is free from the disadvantages described.
