Definitions

  • aqueous slurries which contain a large part or all of the detergent constituents. From an economic point of view, it is important that the slurry is as rich in detergent components as possible. H. 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 is just processing, i.e. H. especially can be pumped and sprayed.
  • Surfactants are an essential component of detergents and cleaning agents.
  • Anionic surfactants are mostly used in the production of detergent slurries as paste-like concentrates with a surfactant content of approx. 30 to approx. 60% by weight; a higher surfactant content would be desirable, but is problematic because the processability of the surfactant concentrates is then no longer guaranteed due to the excess viscosity.
  • 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 causes further problems for the processor. For example, it is often not easy to get gel clumps back into solution, or valves on pumps and containers become blocked.
  • DE-A 2 251 405 describes the salts of certain carboxylic acids, in particular hydroxycarboxylic acids, as viscosity regulators.
  • sulfonated aromatic compounds are suitable for this purpose.
  • DE-A 12328006 mentions sulfates or sulfonates of aliphatic, optionally substituted hydrocarbons as viscosity reducers.
  • the addition of lower alkanols is also listed as a possibility for reducing the viscosity in the publications mentioned.
  • the addition of the well-known hydrotropes such.
  • lower polyalkylene ether glycols with a molecular weight of at least 1,500 can additionally be used together with the sulfates.
  • the object of the present invention is therefore the use of viscosity reducers for aqueous concentrates of anionic surfactants, so that they can be processed in higher concentrations than hitherto or have no increase in viscosity when diluted with water.
  • the invention aims to lower the viscosity of concentrates of alkyl sulfates, alkylarylsulfonates and a-sulforett acid esters.
  • inorganic salts e.g. B. trisodium phosphate (Na 3 P0 4 ) or sodium sulfate (Na 2 S0 4 ) or alkali metal hydroxide as a viscosity regulator has a viscosity-reducing effect, particularly in the case of alkyl sulfate concentrates.
  • the surfactants are present in the concentrates in amounts of approximately 30% by weight ( ⁇ -sulfofatty acid esters, alkyl sulfates) or, as in the case of the alkylarylsulfonates, in amounts of approximately 50 to 60 percent by weight.
  • the viscosity reducer according to the invention, the viscosity of the concentrates at the respective processing temperature, i.e. at the temperature at which the surfactant concentrates are produced, pumped, mixed with other detergent components or sprayed, which is done between about 50 and 90 ° C., to a still processable viscosity of at most 10,000 mPas.
  • Another very important advantage of the use according to the invention is that the surfactant content of the concentrates can be increased by 3 to 15 wt Contain water, which is very important for the economy of production and the quality of the detergents.
  • the viscosity regulators are added to the aqueous surfactant concentrates in amounts of preferably 0.1 to 5% by weight. Amounts of 0.5 to 3% by weight are particularly preferred. This information relates to the aqueous surfactant concentrate. In particular, the amount of the viscosity regulator is lowered by the desired viscosity determined the respective concentrate. In some cases, the maximum achievable viscosity reduction is achieved with an addition of 3% by weight.
  • ethylene oxide with aliphatic alcohols suitable as viscosity regulators are derived in particular from fatty acids from natural fats, for example from coconut oil or tallow fat.
  • fatty acids from natural fats, for example from coconut oil or tallow fat.
  • corresponding Ziegler or oxo alcohol ethoxylates can also be used, a degree of ethoxylation of 30 to 80 moles of ethylene oxide per mole of alcohol, in particular 40 to 60 moles of ethylene oxide per mole of alcohol, giving particularly good results.
  • a particularly effective viscosity regulator for ⁇ -sulfofatty acid esters and alkylarylsulfonate concentrates is, for example, the adduct of 50 moles of ethylene oxide with 1 mole of tallow alcohol.
  • Suitable alkylphenol ethoxylates have in particular 8 to 12, for example predominantly 9 carbon atoms in the alkyl group and preferably 30 to 50 moles of ethylene oxide per mole of alkylphenol in the molecule.
  • the adduct of 40 moles of ethylene oxide with 1 mole of nonylphenol is an example of a viscosity regulator that is particularly effective with concentrates of a-sulfofatty acid esters and alkylarylsulfonates.
  • surfactants are derived in particular from fatty acids with 10 to 20, preferably 12 to 18, carbon atoms and from aliphatic alcohols with 1 to 10, preferably 1 to 2, 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 the alcohol or by sulfonation of a corresponding fatty acid ester. According to both processes, esters of sulfofatty acids are obtained which contain the sulfonic acid group in the a-position.
  • ⁇ -Sulfofatty acid esters which are particularly suitable as surfactants are the alkali metal or ammonium salts of the methyl and ethyl esters of tallow fatty acid with a sulfo group in the ⁇ -position, the acid component of which essentially consists of saturated and unsaturated C, 6 and C 18 fatty acids.
  • Surfactants of this class are the sulfuric acid esters of fatty alcohols.
  • the alcohol component can be saturated or unsaturated and generally has 8 to 24 carbon atoms, preferably 10 to 18 carbon atoms.
  • the alcohol is derived, for example, from coconut oil or, in particular, from tallow fat.
  • FAS are usually in the form of their alkali or ammonium salts.
  • ABS Alkylarylsulfonates
  • ABS are the sulfonation products of alkylbenzene in particular.
  • the alkyl group can be straight-chain or branched, saturated or unsaturated.
  • the alkyl radical preferably has 4 to 16, in particular 6 to 14, carbons.
  • the aqueous surfactant concentrates according to the invention can also contain other surface-active agents and inorganic salts such as sodium chloride and / or sodium sulfate, which in turn can also influence the viscosity of the concentrates.
  • An aqueous concentrate of a-sulfotalg fatty acid methyl ester with approx. 29% by weight of active substance had a viscosity in the temperature range from 40 to 65 ° C without the addition of a viscosity reducer between approx. 31,000 mPas (40 ° C) and approx. 25,000 mPas (65 ° C).
  • the concentrate After addition of 1.5% by weight, based on the concentrate, of nonylphenol + 20 moles of ethylene oxide, the concentrate had a viscosity between approximately 1,500 mPas (65 ° C.) and approximately 14,000 (40 ° C.).
  • the ⁇ -sulph tallow fatty acid methyl ester concentrate from Example 1 was admixed with 1.5% by weight tallow alcohol + 25 mol ethylene oxide.
  • the viscosity was then between approximately 1,500 mPas (65 ° C) and approximately 22,000 mPas (40 ° C).
  • Equal sized additions of tallow alcohol + 50 moles of ethylene oxide or tallow alcohol + 80 moles of ethylene oxide gave comparable or better results, while typical detergent surfactants such as tallow alcohol + 14 moles of ethylene oxide and tallow alcohol + moles of ethylene oxide gave poorer results.
  • a tallow alcohol sulfate paste with 30.1% by weight Without the addition of a viscosity reducer, the active substance had a viscosity between approx. 35000 mPas (55 ° C) and approx. 10000 mPas (80 ° C).
  • the addition of 3% by weight of nonylphenol + 20 moles of ethylene oxide resulted in a viscosity of 9500 mPas (55 ° C) or 3100 mPas (80 ° C).
  • the addition of 3% by weight tallow alcohol + 25 moles of ethylene oxide caused the viscosity to drop to 2100 mPas (55 ° C) or 2100 mPas (80 ° C).
  • the active substance of the surfactant concentrates can be increased by about 3 to 5 percent by weight, depending on the type of surfactant, without the viscosity increasing to a value of about 10,000 mPas; this viscosity represents approximately the upper limit for the pumpability and processability of surfactant concentrates in the detergent slurry.
  • the water content of the surfactant concentrates can be reduced by the same amount; this means considerable progress in the manufacture of industrial detergents.
