Definitions

  • the invention relates to quaternary ammonium compounds in which the ammonium nitrogen atom carries one or two long-chain ester residues or amide residues of etherified hydroxycarboxylic acids, a process for the preparation of such quaternary ammonium compounds and their use in textile aftertreatment agents.
  • Quaternary ammonium compounds which contain one or two long-chain and three or two short-chain aliphatic hydrocarbon residues in the molecule have long been used as textile softeners for treating textiles, in particular for post-treating washed laundry, but also in softening detergents and used in tumble aids. Treatment with such compounds gives the textiles a soft and full feel. When used, however, the treated textile material shows a significantly lower absorbency compared to untreated textiles. Terry towels, tea towels or diapers that have been repeatedly treated with such quaternary ammonium compounds after washing are therefore due to their reduced or delayed water absorption in their performance properties impaired. These adverse effects are due to the fact that the quaternary ammonium compounds applied to the fibers are not or not completely removed during the subsequent washing and therefore the repeated aftertreatment leads to an accumulation of the quaternary ammonium compounds on the fiber.
  • DE-OS 34 02 146 relates to quaternary ammonium compounds with one or two long-chain ester radicals, the acid component of which is derived from branched carboxylic acids of the so-called "Guerbet type".

In addition, they have the disadvantage that they are poorly soluble or poorly dispersible in aqueous systems or tend to hydrolyze therein. This particularly affects those compounds which contain ester bonds.
  • the object of the invention was to provide raw materials for textile aftertreatment agents which do not have the disadvantages of the prior art.
  • Raw materials for textile aftertreatment agents should be available which, in addition to good solubility in aqueous systems, also had the ability to be made up into concentrates for textile aftertreatment agents. Due to the high demand for such concentrates, the so-called "tenfold concentrates" were of particular interest.
  • the raw materials for textile aftertreatment agents should also have the property of not changing the absorbency of the fabrics treated with them, so that this is still completely retained even after several washing or aftertreatment cycles.
  • care should also be taken to use only raw materials that are accessible from natural sources and are therefore renewable.
