Definitions

  • the present invention relates to novel quaternary ammonium compounds of the esterquat type, to a process for their preparation, and to the use of these in formulations.

  • esterquat is generally understood to mean di- or trialkanolamines esterified with fatty acids in their salt form.
  • quaternized fatty acid alkanolamine ester salts are known substances that can be obtained by relevant methods of preparative organic chemistry.

  • Alkanolamine is prepared, which is then quaternized with a suitable reagent.
  • Dispersant preferably fatty alcohols, is performed.
  • Esterquats have a more favorable ecotoxicological behavioral profile compared to alkyl quats and also have improved biodegradability than alkyl quats due to the presence of ester linkage.

In an excessive bleaching, it may even be up to 45% (KF de Polo, A Short Textbook of Cosmetology, 2000, Verlag für chemische Industrie, H. Ziolkowsky GmbH). And even the daily washing, combing and blow-drying of the hair leaves traces.
  • the undesirable consequences are, for example, a rough hair surface, a reduced mechanical stability and an increase in the electrostatic charge. Hair breakage, the formation of "split ends", difficult combing and loss of natural shine are the result.
  • Conditioners are designed to protect the hair from these negative effects, but should not negatively impact the environment if possible.
  • the conditioner must be able to raise to the hair. Because of the anionic centers on the hair surface based on protein structures, cationic compounds are a preferred class of conditioning agents because they provide the necessary affinity for the hair. In the case of already existing hair damage, the number of anionic groups is even increased, due to the presence of oxidized protein structures such. As the above cysteic acid. Especially in these damaged areas, cationic conditioning agents can reach their full potential
