Definitions

  • the invention relates to alk (en) ylglycerol ether carboxylic acids, a process for their preparation and their use as cleaning and foaming agents and as an emulsifier.
  • anionic surfactants which are not only responsible for the cleaning effect but also for the formation of foam. Accordingly, there is still a need in the market to provide new anionic surfactants which, in addition to the cleaning and foaming effect, also have other positive properties, such as good tolerance to the mucous membrane and, moreover, can be produced inexpensively, simply and, if possible, in a salt-free form.
  • the object of the invention was therefore to provide new anionic surfactants and a process for their preparation which have the properties listed above and can be prepared simply and relatively inexpensively and, if possible, in salt-free form.
  • the present invention relates to alk (en) ylglycerol ether carboxylic acids, obtainable by mono- and / or dialk (en) ylglycerol ethers and their addition products with ethylene and / or propylene oxide of the formula (I)
  • R 1 and R 2 independently of one another for H or a linear and / or branched alkyl and / or alkenyl group having 4 to 22 carbon atoms, but at least one of the radicals R 1 and R 2 for a linear and / or branched alkyl and / or alkenyl group containing 4 to 22 carbon atoms, a is a C2H4O- and / or C3H ⁇ O group, and n, m and p are independently 0 or Zah ⁇ len from 0.5 to 10, are reacted with ⁇ -halocarboxylic acids of formula (II )
  • XCR 3 R 4 COOH (" in which R 3 represents H or a CH3 group, R 4 represents H or a linear and / or branched alkyl and / or alkenyl group having 1 to 6 carbon atoms and X represents halogen, in the presence of alkali.

  • R 1 and R 2 independently of one another for H or a linear and / or branched alkyl and / or alkenyl group having 4 to 22 carbon atoms, but at least one of the radicals R 1 and R 2 for a linear and / or branched alkyl and / or alkenyl group with 4 to 22 carbon atoms
  • A represents a C2H4O and / or CaH ⁇ O group and n, m and p independently of one another represent 0 or numbers from 0.5 to 10, with ⁇ -halocarboxylic acids of the formula (II),

  • R 4 is H or a linear and / or branched alkyl and / or alkenyl group having 1 to 6 carbon atoms and X is halogen and preferably chloride, in the presence of alkali.
  • alk (en) ylglycerol ether carboxylic acids have good foaming behavior and good cleaning action and, in addition to their surfactant properties, have good emulsifying properties. Accordingly, these compounds can be used in a variety of surface active formulations in which the presence of anionic surfactants or emulsifiers is desired, e.g. in detergents, dishwashing detergents and cleaning agents as well as cosmetic emulsions. At the same time, they are well tolerated by dermatology and can be prepared by simply reacting mono- and / or dialk (en) ylglycerol ether and halocarboxylic acids in the presence of alkali. It is particularly advantageous that these compounds are obtained in an almost salt-free form, and disruptive effects due to the presence of salt ions can be avoided.
