Definitions

  • amphoteric surfactants are described for example in DE-OS 30 18 201. Then they are prepared by condensation of C 6 -C 22 fatty acids with the aminoalkylalkanolamides of the general formula given in a molar ratio of 1: 1 to 1: 1.5 and subsequent alkylation with vinylogenic compounds, the alkylation products, depending on the structure and extent of the reaction, if appropriate can have quaternized nitrogen atoms. Since the condensation products of fatty acid and aminoalkylalkanolamine generally contain a more or less high proportion of diamide, it is preferred Before the alkylation, an alkaline pretreatment is carried out, the diamide being converted into the monoamide. In the subsequent alkylation, this leads to improved amphoteric surfactants with, in particular, increased storage stability.
  • saturated or unsaturated C 12 -C 22 fatty acids or corresponding fatty acid esters preference is given to using saturated or unsaturated C 12 -C 22 fatty acids or corresponding fatty acid esters. These can be present as pure components or preferably as mixtures of natural or synthetic origin. Examples of this are mixtures of coconut fatty acid, tallow fatty acid, trans-fatty acid, rapeseed oil fatty acid, and corresponding methyl esters or triglycerides.
  • the amine component is preferably aminoethylethanolamine.
  • the reaction is preferably carried out in the molar ratio of fatty acid or fatty acid residue: aminoalkylalkanolamine, such as 1: 1 to 1: 1.5.
  • Particularly suitable vinylogous compounds are acrylic acid and methacrylic acid and their esters, such as methyl acrylate or methyl methacrylate.
  • the amphoteric surfactants are formed by subsequent saponification of the alkylation products with aqueous sodium hydroxide solution.
  • amphoteric surfactants described have high emulsion resistance to the hardness constituents of water and to alkali salts.
  • leather and fur greasing with good greasing of the leather they result in a pleasantly soft, slimy and supple handle. Colorings are very brilliant with good levelness.
  • Suede leather has a silky fiber with a nice writing effect.
  • amphoteric surfactants can be used alone or in combination with conventional leather fatliquoring agents based on sulfated, sulfitized or chlorosulfonated oils or fats, as well as in combination with anionic and / or nonionic emulsifiers, such as alkyl benzene, fatty alcohol sulfates, Fettalkoholethosulfaten, Fettklarealkanolamidethosulfaten, sulfosuccinates, fatty alcohol and alkylphenol ethylene oxide adducts be used.
  • the proportion of amphoteric surfactants can be 10-100% by weight, based on the fatty substance.
  • amphoteric surfactants are leather and fur greasing agents which can be used without problems. They are used in the customary manner in the form of aqueous emulsions in an amount of 3-15% by weight of active substance, based on the shaved weight of the leather.
  • amphoteric surfactant 97.2 g (0.25 mol) of the aminoamide were mixed in a three-necked flask with stirring and a thermometer at 90 ° C. with 4 g of 50% sodium hydroxide solution and 25 g of water and for 1 hour at 90-95 ° C. stirred to destroy diamide. Then 316.6 g of water and 18.0 g (0.25 mol) of acrylic acid were added and the mixture was stirred at 85 ° C. for 5 hours. A finely divided dispersion with 25% active substance was obtained.
  • amphoteric surfactant 862.5 g (1.9 mol) of the aminoamide, 30.5 g of 50% sodium hydroxide solution, 2969.5 g of water and 137.5 g (1.91 mol) of acrylic acid were added in the order given below 1 specified, implemented. Here too, a finely dispersed product with 25% active substance was obtained.
  • amphoteric surfactant 847 g (2.14 mol) of the aminoamide were dispersed in 2000 g of water and reacted with 153 g (2.13 mol) of acrylic acid by stirring at 80-90 ° C. for 8 hours.
  • the product obtained was a viscous brown liquid with 33% active substance.
  • amphoteric surfactant 1267 g (3.5 mol) of the aminoamide, 252 g (3.5 mol) of acrylic acid and 4500 g of water were reacted. A viscous brown liquid with 25% active substance was obtained.
  • Example 3 50 parts of product Example 3 50 parts of sulfited ester oil 1: 1 to 1: 2 emulsify with water and apply with a brush. Soft, plump, light furs.
  • the leather is very soft (softyl leather) with good fullness, uniform, brilliant aniline coloring.
