Definitions

  • aqueous slurries which contain a large part of the detergent constituents or also all detergent constituents. From an economic point of view, it is important that the slurry is as rich in detergent components as possible, i.e. is as low in liquid fiber as possible. The lowest possible amount of water is therefore used to prepare the slurries. Concentration is limited by the highest possible viscosity at which the slurry can just be processed.
  • anionic surfactants which are mostly used as paste-like concentrates in the form of their alkali or ammonium salts in the production of the detergent slurries.
  • the surfactant content of technical concentrates is, for example in the case of the ⁇ -sulfotalg fatty acid methyl ester, about 30% by weight. Pastes with a higher surfactant content can no longer be processed.
  • a special feature of the rheological behavior of surfactant concentrates is that they do not react to the addition of water with a reduction in viscosity, but first with a thickening to a gel-like state, which poses further problems for the processor. For example, it is often not. easy to get formed lumps of gel back into solution, or it clogs valves of pumps and containers.
  • DE-OS 22 51 405 describes the salts of certain carboxylic acids, in particular hydroxycarboxylic acids, as viscosity regulators.
  • sulfonated aromatic compounds are suitable for these purposes.
  • DE-OS 23 26 006 mentions sulfates or sulfonates of aliphatic, optionally substituted hydrocarbons as viscosity regulators. The addition of lower alkanols is also listed as a possibility for reducing the viscosity in the publications mentioned.
  • Object of the present invention is therefore the provision of substances for improving the F l ware- behavior of aqueous technical anionic surfactant concentrates, in particular of ⁇ -sulfo fatty acid esters, so that they are processed as previously in higher concentrations or when diluted with water, no increase in the Have viscosity.
  • viscosity regulator for highly viscous technical surfactant concentrates of the type of synthetic anionic surfactants, in particular of ⁇ -sulfofatty acid esters with at least 30% by weight of ⁇ -sulfofatty acid esters, the viscosity regulator being used in amounts of 1-15% by weight, based on the amount of surfactant , adds, so that a reduction in the viscosity of the concentrates to a maximum of 10,000 mPas at 70 ° C occurs, can achieve the desired effects.
  • surfactant content can be adjusted to values of approximately approximately 60% by weight in the industrial production of the surfactant concentrates without the viscosity being the upper limit of approximately 10,000 mPas permissible for processability exceeds, whereby surfactant concentrates with lower water ballast are obtained.
  • these concentrates are diluted, the temporary increase in viscosity which is otherwise observed does not occur, which is also advantageous for processing.
  • the viscosity regulators are preferably added to the aqueous industrial anionic surfactant concentrates in amounts of approx. 10% by weight, i.e. in particular 7 to 12% by weight, based on the surfactant content, the desired viscosity reduction of the concentrate being determined by the amounts of the viscosity regulator added.
  • the compounds suitable as viscosity regulators are derived, for example, from acetic acid, succinic acid or malonic acid.
  • the sodium salts of the compound mentioned are particularly suitable.
  • Examples of the combinations mentioned are the sodium salts of monochloroacetic acid, ot-sulfosuccinic acid, ⁇ -sulfomalonic acid, ⁇ -sulfoacetic acid, ⁇ -sulfoacetic acid methyl ester, cyanoacetic acid and ethyl cyanoacetate.
  • the compounds mentioned can be added individually or in a mixture.
  • the viscosity-reducing effect is particularly pronounced at low pH values, for example at pH values below 7. This is in some cases another advantage of the use of the compounds mentioned according to the invention.
  • the addition of other compounds with electron-withdrawing groups also reduces the viscosity of anionic surfactant concentrates; Examples of such compounds are the sodium salts of vinyl sulfonate and nitrilotriacetic acid.
  • Dipropylene glycol monomethyl ether is also suitable as a viscosity regulator.
  • This type d) compound of the aforementioned viscosity regulators is an ether alcohol which contains two propylene glycol units and a methoxy group.
  • Viscosity regulation is a particular problem for concentrates of ⁇ -sulfofatty acid esters, since concentrates with a surfactant content of more than about 30% by weight are no longer easy to process. Without the viscosity problem, it would be technically possible to produce surfactant concentrates with up to about 80% by weight of surfactant. The reduction in viscosity of ⁇ -sulfofatty acid ester concentrates is therefore a particular object of the present invention.
  • the ⁇ -sulfofatty acid esters to the concentrates of which the viscosity regulators mentioned are added, are derived from fatty acids with 10 to 20, preferably 12 to 18, carbon atoms and from aliphatic alcohols with 1 to 10, preferably 1 to 4, carbon atoms in the molecule.
  • the sulfo group is introduced either by sulfonation of the fatty acid and subsequent esterification of the carboxyl group with alcohol or by sulfonation of a corresponding fatty acid ester. According to both methods, esters of sulfo fatty acids are obtained which contain the sulfo acid group in the ⁇ -position.
  • Particularly suitable ⁇ -sulfofatty acid esters are the alkali or ammonium salts of ethyl and especially the methyl ester of tallow fatty acid with a sulfo group in the ⁇ -position, the acid component of the fatty acid esters consisting essentially of saturated C 16 and C 18 fatty acids.
  • the salts are prepared by neutralizing the acidic esters with the appropriate bases.
