Definitions

  • dextrins for example oligomers or polymers of carbohydrates, which can be obtained by partial hydrolysis of starches.
  • the hydrolysis can be carried out by customary, for example acid or enzyme catalyzed processes. Preference is given to hydrolysis products having average molecular weights in the range from 400 to 500,000.
  • a polysaccharide with a dextrose equivalent (DE) in the range from 0.5 to 40, in particular from 2 to 30 is preferred, DE being a customary measure for the reducing effect of a polysaccharide compared to dextrose, which has a DE of 100.
  • DE dextrose equivalent
  • Suitable co-builders are oxydisuccinates and other derivatives of disuccinates, preferably ethylenediamine disuccinate. Glycerol disuccinates and glycerol trisuccinates are also particularly preferred in this context. Suitable amounts are in zeolith City City and / or silicate-containing formulations at 3 to 15 wt .-%.
  • Other useful organic cobuilders are, for example, acetylated hydroxycarboxylic acids or their salts, which may optionally also be present in lactone form and which contain at least 4 carbon atoms and at least one hydroxyl group and a maximum of two acid groups.
  • Suitable soil repellents are those which preferably contain ethylene terephthalate and / or polyethylene glycol terephthalate groups, the molar ratio of ethylene terephthalate to polyethylene glycol terephthalate being in the range from 50:50 to 90:10. More specifically, the molecular weight of the linking polyethylene glycol units is in the range of 750 to 5,000, that is, the degree of ethoxylation of the polymers containing polyethylene glycol groups may be about 15 to 100.
  • the polymers are characterized by an average molecular weight of about 5000 to 200,000 and may have a block, but preferably a random structure.
  • the following examples illustrate the process according to the invention for the cold production of liquid detergents.
  • the starting materials were mixed according to Table 1 at different temperatures (30, 23, 5 ° C based on the water in the template) with vigorous stirring and made up the approaches with water of 23 or 5 ° C to 100 parts.
