Definitions

  • Liquid detergent containing sulfo-oleic acid salts Liquid detergent containing sulfo-oleic acid salts
  • DE 35 34 082 discloses liquid, manually usable, skin-friendly dishwashing detergents with strong foam development and good cleaning power, which use fatty alkyl sulfates or fatty alkyl ether sulfates as well as fatty acid alkanolamides and fatty alkyl monoglucosides with 10 to 18, preferably 12 to 14, carbon atoms in the fatty alkyl radical as synthetic anionic surfactants and contain solvents, hydrotropes, salts and the like. From DE 37 06 015.5 alkyl glucoside-containing, manually applicable liquid dishwashing detergents are also known, which contain a substantial proportion of di-n-alkyl sulfosuccinates. Finally, EP 70074 A2 also describes cleaning agents which contain combinations of alkyl polyglucosides and fatty alcohol sulfates or fatty alcohol ether sulfates.
  • liquid cleaning agents For manually usable dishwashing detergents, a viscosity range from about 10 to about 1000 mPas, preferably from about 100 to about 400 mPas, has become established.
  • Solutions of the cleaning-active substances in water are therefore usually added to solvents, such as low molecular weight mono- or dialcohols and / or hydrotropes, such as short-chain alkylbenzenesulfonates. to dilute them, or uses electrolytes, such as table salt, to raise the viscosity to low viscosity active substance solutions.
  • solvents such as low molecular weight mono- or dialcohols and / or hydrotropes, such as short-chain alkylbenzenesulfonates.
  • electrolytes such as table salt
  • the present invention therefore relates to liquid, aqueous cleaning agents, in particular for the manual cleaning of dishes, based on synthetic anionic or mixtures of anionic and / or nonionic surfactants and, if appropriate, other conventional constituents, in particular solvents, hydrotropes and salts are characterized in that they contain sulfo-oleic disalts as hydrotropes. Their amount is preferably 15 to 40, in particular 20 to 35,% by weight, based on the content of other synthetic anionic surfactants.
  • the sodium salts are preferred for reasons of economy.
  • Cleaning agents based on fatty alkyl sulfates and / or fatty alkyl ether sulfates, fatty alkyl glucosides and fatty acid alkali are particularly preferred.
  • Disulfonic acid disalts can be prepared by processes as described in GB 1 278421 or in DE 3926344.4. They have good network properties both in aqueous and in aqueous alkaline solution and are stable in hard water. In addition, these compounds have a very good solubility in water, are readily biodegradable and very kind to the skin. The degree of sulfonation can fluctuate within certain limits, which also slightly influences the hydrotope effect, but not in the clear tendency.
  • sulfo oleic acid salts can lower the viscosity of solutions of anionic surfactants, since the saturated salts of the saturated Sulfofatty acid with the same number of carbon atoms, ⁇ -sulfostearic acid, is not able to do this. In contrast to the disalt of sulfo oleic acid, it is sparingly water-soluble. Only the shorter-chain ⁇ -sulfofatty acid disalts with 10 to 14 carbon atoms in the molecule are known as viscosity-reducing compounds for liquid or pasty detergent active substance concentrates (cf. DE 1 216470 and DE 1 221 391).
  • Alkyl sulfates or alkyl ether sulfates are used as synthetic anionic surfactants.
  • the invention creates a cleaning agent made from three different types of surfactants, the hydrophobic part of which is produced entirely from renewable raw materials (fats).
  • the hydrophilic part of the molecule also consists of a renewable raw material (sugar).
  • anionic surfactants which have a petrochemical base, in particular alkylbenzenesulfonate, are therefore not used. However, their viscosity in aqueous solution is also reduced according to the invention.
  • the preferred alkyl sulfates or alkyl ether sulfates are commercially available, they have a straight-chain aliphatic C12-C18- 'preferably Cj2-Ci4 radical.
  • the associated cation is preferably an alkali metal or ammonium ion.
  • alkyl ether sulfates the degree of ethoxylation is 1 to 5; preferred is the use of an alkyl ethersulfatge Steam, consisting of 50 wt .-% of a C j 2- lkylethersulfats A and 50 wt .-% of a Ci4-alkyl ether sulfate having from 1 to 5, preferably 2 to 4 ethylene oxide instead of the conventionally used alkylether sulfate mixture, which contains the same components in a weight ratio of 70:30, is advantageous because it leads to a reduction in skin irritation without reducing the known good washing power of such agents.
  • alkyl ether sulfates with less than 12 or more than 14 carbon atoms in the alkyl radical change these good results only insignificantly, but should be avoided if necessary.
  • the amount of alkyl and / or alkyl ether sulfates used is 2 to 25, preferably 3 to 20 percent by weight, based on the total agent.
  • the fatty acid alkanolamides used have an alkyl group with 8 to 18, preferably 10 to 14 carbon atoms in the fatty acid residue, while the amide group either with two hydroxyalkyl groups with 1 to 3 carbon atoms (dialkanolamide) or with such a hydroxyalkyl group and with hydrogen or a C-C3 ⁇ Alkyl group is substituted. These compounds are used in an amount of 1 to 15, preferably 1 to 5 percent by weight, based on the total agent. Mixtures of fatty acid mono- and dialkanolamides are preferably used.
  • the fatty alkyl glucosides preferably used as nonionic surfactants are understood here to mean compounds with an average of less than two glucose units per fatty alkyl radical, in particular those with 1 to 1.4 glucose units.
  • the fatty alkyl radical has 10 to 18, in particular essentially 12 to 14, carbon atoms.
  • "Fatty alkyl” is understood to mean the residues of the fatty alcohols produced by hydrogenation of natural fatty acids, which are wholly or predominantly saturated, or which also comprise unsaturated portions.
  • fatty alcohol ethoxylates having 10 to 18, preferably 12 to 14 carbon atoms in the fatty alkyl radical and 2 to 5, preferably 3 to 4, ethylene oxide groups in the molecule.
  • the amount of the alkyl glucosides used according to the invention is 2 to 25, preferably 3 to 20% by weight, based on the total agent, this amount preferably being equal to or less than the combined amount of sulfate surfactant and fatty acid alkanolamide.
  • the effect according to the invention also occurs when the surfactants mentioned are partially replaced by amphoteric surfactants such as.
  • B. Acylamidopropyldimethylammo ⁇ iumbetain the performance increases in rinsing capacity and improvements in storage stability can cause. They can be present in the total product in amounts of 1 to 5, preferably 1.5 to 3% by weight. As the examples show, viscosities can be achieved according to the invention as desired for the finished product.
  • small amounts of conventional solvents such as low molecular weight alkanols with 1 to 4 carbon atoms in the molecule, preferably ethanol and isopropyl alcohol, can of course also be used.
  • the amounts used are about 3 to 5 percent by weight, based on the total agent, and are thus clearly below the amounts customary hitherto.
  • Thickeners such as urea, sodium chloride, ammonium chloride and magnesium chloride can also be used individually or in combination.
  • Other common optional additives are corrosion inhibitors, preservatives, dyes and perfume oils.
  • Alkanolamines such as ethylene glycol, 1,2-propylene glycol or glycerol, for example, can serve as solubilizers, for example for dyes and perfume oils.
  • the amounts used are between about 0.1 and 5 percent by weight, based on the total agent. The remainder to be calculated for a total of 100 percent by weight for the total composition consists of water.
  • liquid cleaning agents according to the invention according to the following examples were obtained by stirring the individual components together and leaving the mixture to stand until there were no bubbles.
  • the sodium salts were used as anionic surfactants.
  • OSSD oleic acid sulfonate disodium salt degree of sulfation (degree of conversion)
  • KFS-MEA Coconut fatty acid monoethanolamide ⁇ -Di: ⁇ -sulfo-Ciö-Cis-fatty acid Di-Na salt
  • ABS C8-Ci3-alkylbenzenesulfonate
  • Betaine Dimethyl-Cs-Cig-Acylamidopropylacetobetaine
  • the percentages relate to the active substance content.
  • ABS 8200 (according to Brookfield, spindle 7,
  • the sulfo-oleic disodium salt reduces the viscosity of the surfactant concentrates when using smaller amounts than would be required for ethanol (cf. Examples 4 and 5 and 9 and 10).
  • disulphate salts of ⁇ -sulfostearic acid increase the viscosity (cf. Examples 2 and 6 and 14 and 15 or 17 and 18).
