Definitions

  • the invention relates to the use of selected sugar surfactants for the degreasing of leather and Furs.
  • the invention relates to the use of (a) alkyl and / or alkenyl oligoglycosides and / or (b) Fatty acid N-alkylpolyhydroxyalkylamides for degreasing leather and furs.
  • the sugar surfactants mentioned are not only for the greasing of leather and fur, especially depending on the working conditions for the opposite purpose, namely the degreasing of these materials.
  • the sugar surfactant show a performance that corresponds to that of the most effective commercial products.
  • Alkyl and alkenyl oligoglycosides which are suitable as sugar surfactant component (a) are known nonionic surfactants which follow the formula ( I ) R 1 O- [G] p (I) in which R 1 is an alkyl and / or alkenyl radical having 4 to 22 carbon atoms, G is a sugar radical having 5 or 6 carbon atoms and p is a number from 1 to 10. They can be obtained according to the relevant procedures in preparative organic chemistry. As representative of the extensive literature, reference is made here to the documents EP-A1-0 301 298 and WO 90/03977 .
  • the alkyl and / or alkenyl oligoglycosides can be derived from aldoses or ketoses with 5 or 6 carbon atoms, preferably glucose.
  • the preferred alkyl and / or alkenyl oligoglycosides are thus alkyl and / or alkenyl oligo glucosides.
  • the index number p in the general formula (I) indicates the degree of oligomerization (DP), ie the distribution of mono- and oligoglycosides, and stands for a number between 1 and 10.
  • Alkyl and / or alkenyl oligoglycosides with an average degree of oligomerization p of 1.1 to 3.0 are preferably used. From an application point of view, preference is given to those alkyl and / or alkenyl oligoglycosides whose degree of oligomerization is less than 1.7 and in particular between 1.2 and 1.4.
  • the alkyl or alkenyl radical R 1 can be derived from primary alcohols having 4 to 11, preferably 8 to 10, carbon atoms. Typical examples are butanol, capronic alcohol, caprylic alcohol, capric alcohol and undecyl alcohol and their technical mixtures, such as are obtained, for example, in the hydrogenation of technical fatty acid methyl esters or in the course of the hydrogenation of aldehydes from Roelen's oxosynthesis.
  • the alkyl or alkenyl radical R 1 can also be derived from primary alcohols having 12 to 22, preferably 12 to 14, carbon atoms.
  • Typical examples are lauryl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidyl alcohol, petroselinyl alcohol, arachyl alcohol, gadoleyl alcohol, behenyl alcohol, erucyl alcohol, brassidyl alcohol and their technical mixtures, which can be obtained as described above.
  • Alkyl oligoglucosides based on hardened C 12/14 coconut alcohol with a DP of 1 to 3 are preferred.
  • the sugar surfactants of component (b), the fatty acid N-alkylpolyhydroxyalkylamides, are also nonionic surfactants and follow the formula ( II ), in the R 2 CO for an aliphatic acyl radical having 6 to 22 carbon atoms, R 3 for hydrogen, an alkyl or hydroxyalkyl radical with 1 to 4 carbon atoms and [Z] for a linear or branched polyhydroxyalkyl radical with 3 to 12 carbon atoms and 3 to 10 hydroxyl groups stands.
  • the fatty acid N-alkyl polyhydroxyalkylamides are known substances which can usually be obtained by reductive amination of a reducing sugar with ammonia, an alkylamine or an alkanolamine and subsequent acylation with a fatty acid, a fatty acid alkyl ester or a fatty acid chloride.
  • a reducing sugar with ammonia
  • an alkylamine or an alkanolamine and subsequent acylation with a fatty acid, a fatty acid alkyl ester or a fatty acid chloride.
  • the fatty acid N-alkylpolyhydroxyalkylamides are preferably derived from reducing sugars having 5 or 6 carbon atoms, in particular from glucose.
  • the preferred fatty acid N-alkylpolyhydroxyalkylamides are therefore fatty acid N-alkylglucamides as represented by the formula (III):
  • the preferred fatty acid N-alkylpolyhydroxyalkylamides used are glucamides of the formula ( III ) in which R 3 is hydrogen or an alkyl group and R 2 CO is the acyl radical of caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, palmoleic acid, stearic acid, Isostearic acid, oleic acid, elaidic acid, petroselinic acid, linoleic acid, linolenic acid, arachic acid, gadoleic acid, behenic acid or erucic acid or their technical mixtures.
  • R 3 is hydrogen or an alkyl group
  • R 2 CO is the acyl radical of caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, palmoleic acid, stearic acid, Isostearic acid, oleic acid, elaidic acid, pet
  • Fatty acid N-alkylglucamides of the formula ( II ) which are obtained by reductive amination of glucose with methylamine and subsequent acylation with lauric acid or C 12/14 coconut fatty acid or a corresponding derivative are particularly preferred.
  • the polyhydroxyalkylamides can also be derived from maltose and palatinose.
  • fatty acid N-alkylpolyhydroxyalkylamides are also the subject of a large number of publications. Their use as a thickener is known, for example, from European patent application EP-A1 0 285 768 (Hüls). French published patent application FR.A 1 580 491 (Henkel) describes aqueous detergent mixtures based on sulfates and / or sulfonates, nonionic surfactants and, if appropriate, soaps, which contain fatty acid N-alkylglucamides as foam regulators. Mixtures of short and long chain glucamides are described in German Patent DE-C1 44 00 632 (Henkel).
  • German published applications DE-A1 42 36 958 and DE-A1 43 09 567 also report on the use of glucamides with longer alkyl residues than pseudoceramides in skin care products and on combinations of glucamides with protein hydrolyzates and cationic surfactants in hair care products.
  • the previously unpublished patent application DE-P 195 04 643 by the applicant also discloses the use of alkyl oligoglucosides and / or fatty acid N-alkyl glucamides as fatliquoring agents for leather and furs.
  • the degreasing of the leather and furs can be carried out in a manner known per se. Usually if you put the materials in a kettle or a tub, they soak in warm water, preferably alkaline lye and add the degreasing agent, its amount - based on the solids content of the agent on the one hand and the pimple nakedness weight of the naked or Furs, on the other hand, can total 1 to 15 and preferably 5 to 10% by weight.
  • the addition of the degreasing agent is preferably carried out in portions, with between the individual dosages the lye can be drained and replaced with new one.
  • degreasing can be salts such as alkali and / or alkaline earth carbonates or bicarbonates, sulfites and / or bisulfites but preferably sodium bicarbonate can be used.
  • salts such as alkali and / or alkaline earth carbonates or bicarbonates, sulfites and / or bisulfites but preferably sodium bicarbonate can be used.
  • To degreasing usually the further steps of leather or fur preparation such as, for example, close washing, pimples, tanning, dyeing and greasing.
  • the liquor was successively added 2% of a sodium sulfite / bisulfite mixture, 1.5% sodium hydrogen carbonate and 50% water added and a total of about 3 let h act. After degreasing, the liquor was washed with 200% water, until the wash water remained clear. The remaining half of the fur pairs became analogous procedure, but instead of the glucoside a fatty alcohol ethoxylate from the trade (Fluidol® BN) used. Both pairs of fur were then treated in the same way: the pairs were - each separately - pickled and tanned.
  • the residual fat content in each of the individual skins was then determined and the number of Test skins averaged.
  • the fat content was 2.34 % By weight, corresponding to a degree of degreasing of 75% of theory, for the purposes of the invention with skins treated with glucoside resulted in a residual fat content of 2.28% by weight, corresponding to 76% of theory.
