Definitions

  • the invention relates to a process for the preparation of storage-stable nonionic surfactants with improved crystallization resistance, in which alk (en) yl oligoglycosides are added to selected crystallization moderators.
  • Alk (en) yl oligoglycosides are important non-ionic surfactants which, due to their good detergent properties and high environmental compatibility, are being used increasingly in detergents, dishwashing detergents and cleaning agents.
  • alk (en) yl oligoglycosides available for a certain period of time, for example as aqueous solutions or pastes, until they are finished.
  • aqueous alk (en) yl oligoglycosides show a strong tendency to crystallize, the homogeneity of such preparations decreases over time when they are stored under ambient conditions and form them agglomerates containing water of crystallization, which greatly reduce the pumpability of the products.
  • Alk (en) yl oligoglycosides are therefore usually not stored at room temperature, but at temperatures of at least 40 ° C. In this way, crystallization of the preparations can be largely prevented, but storage at elevated temperature is associated with additional effort and can also severely impair the color quality of the products.
  • the object of the invention was therefore to develop a process by means of which alk (en) yl oligoglucosides can be stored at temperatures below 40 ° C. without impairing the pumpability of the products through the formation of crystalline agglomerates.
  • the invention relates to a process for the preparation of storage-stable nonionic surfactants, in which aqueous preparations containing alkyl and / or alkenyl oligoglycosides of the formula (I) R 1 O- [G] p (I) in R 1 for a linear alkyl and / or alkenyl radical with 6 to 22 carbon atoms, G stands for a sugar radical with 5 or 6 carbon atoms and p stands for numbers from 1 to 10, Crystallization moderators added, which are selected from the group consisting of a) alkyl oligoglycosides based on short-chain primary alcohols
  • alkyl oligoglycosides based on Guerbet alcohols b) alkyl oligoglycosides based on Guerbet alcohols, c) alkyl oligoglycosides based on polyols,
  • Alkyl and alkenyl oligoglycosides are known substances that can be obtained by the relevant methods of preparative organic chemistry. Representative of the extensive literature, reference is made here to the documents EP-A1-0 301 298 and WO 90/3977.
  • the alkyl and / or alkenyl oligoglycosides can differ from aldoses or ketoses with 5 or 6 carbon atoms. preferably derive the glucose.
  • the preferred alkyl and / or alkenyl oligoglycosides are thus alkyl and / or alkenyl oligoglucosides.
  • 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, 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.
  • Alkyl oligoglycosides based on short-chain primary alcohols This includes methyl and butyl glucosides.
  • Alkyl oligoglycosides based on Guerbet alcohols a) Alkyl oligoglycosides based on short-chain primary alcohols. This includes methyl and butyl glucosides.
  • Alkyl oligoglycosides based on Guerbet alcohols a) Alkyl oligoglycosides based on short-chain primary alcohols. This includes methyl and butyl glucosides.
  • Alkyl oligoglycosides based on Guerbet alcohols a) Alkyl oligoglycosides based on short-chain primary alcohols. This includes methyl and butyl glucosides.
  • Alkyl oligoglycosides based on Guerbet alcohols a) Alkyl oligoglycosides based on short
  • alkyl oligoglycosides which are obtained by acid-catalyzed acetalization of glycoses, in particular glucose, with Guerbet alcohols and which follow the formula (II),
  • Typical examples are alkyl oligoglucosides with a DP degree of 1.3 to 1.6 based on 2-ethylhexanol or 2-hexyldecanol.
  • Alkyl oligoglycosides based on polyols These are understood to mean alkyl oligoglycosides which are obtained by acid-catalyzed acetalization of glycoses, in particular glucose with polyols, and which follow the formula (III),
  • R 4 O- (CH 2 CH 2 O) n H (V) in which R 4 represents a linear alkyl and / or alkenyl radical having 8 to 22 carbon atoms and n represents numbers from 1 to 10. Typical examples are adducts of an average of 5 to 7 moles of ethylene oxide with technical grade C 12/14 coconut oil alcohol. f) polyethylene glycols of the formula (VI,
  • Typical examples are polyethylene glycols with an average molecular weight of 300 to 600.
  • the crystallization moderators can be added to the alkyl and / or alkenyl oligoglycosides in amounts of 0.01 to 7, preferably 1 to 3% by weight, based on the alkyl and / or alkenyl oligoglycosides.
  • iron (III) ions in quantities of 0.01 to 0.5% by weight in order to reliably prevent discoloration of the products catalyzed by Fe ions.
  • the process according to the invention is used to stabilize aqueous preparations which contain alkyl and / or alkenyl oligoglycosides.
  • the solids content of these preparations can be 1 to 70% by weight, preferably 30 to 60% by weight, the problem of reduced storage stability due to crystallization only becoming more important with products of higher concentration.
  • the aqueous preparations can also contain other ingredients customary for detergents, dishwashing detergents and cleaning agents than there are, for example: anionic, nonionic, amphoteric or zwitterionic surfactants, oil bodies, builders, hydrotropes, adjusting agents, optical brighteners, graying inhibitors , Defoamers and perfumes.
  • aqueous preparations which can be obtained by the process according to the invention and contain alkyl and / or alkenyl oligoglycosides are color-stable at storage temperatures of about 30 ° C. and show practically no tendency towards crystallization; at the same time the solubility limit is lowered. They are therefore suitable for the production of detergents, dishwashing detergents and cleaning products and products for hair and body care, in which they can be present in amounts of 1 to 50, preferably 10 to 30% by weight, based on the composition.
  • Fe (III) ions used as FeCl 3
  • SET melting end points
  • Tab. 1 shows the melting end points for the hydrates with the highest SET. The results are to be assessed in such a way that when the coconut alkyl oligoglucoside is stored above the stated SET there is no crystallization and below the SET there is only a strongly delayed crystallization.
