Definitions

  • Two-component detergents are understood to mean preparations consisting of two separately produced and stored detergent constituents which are only combined with one another immediately before or at the start of the washing process.
  • the present invention relates to such an agent in which the liquid concentrate contains one component as a fatty acid and further surfactants and the other component contains the alkali required for soap formation.
  • GB-A 338 121 discloses a washing process using a two-component detergent.
  • the first component consists of soap-forming fatty acids, such as palmitic acid, stearic acid or oleic acid, which can be present in a mixture with emulsifiers or solvents, such as sulfated olive oil, hydrocarbons, tertpentine and chlorinated hydrocarbons.
  • the second component contains the alkalis required for soap formation, such as alkali metal hydroxides, carbonates, bicarbonates and silicates, and is only combined with the first component in the wash liquor. Bleaching components can also be added. This process has a number of disadvantages, which play a role in particular in commercial laundries with a high degree of automation.
  • the fatty acids mentioned are difficult to convey and dose automatically, while the use of solvents from the series of hydrocarbons or chlorinated hydrocarbons poses considerable problems, such as increased risk of fire and explosion or toxicological concerns.
  • the reaction between the fatty acids which are not sufficiently finely dispersed in the washing liquid and the alkali is relatively slow, especially at washing temperatures below 65 ° C. the reaction is also inhibited or partially prevented by the laundry present, so that fatty acid deposits can form on the laundry.
  • FR-A 1 460 904 starts from aqueous fatty acid emulsions suitable for soap formation, which are combined with the washing alkalis in the wash liquor.
  • the fatty acid which is preferably technical oleic acid or a low-melting fatty acid mixture (titer 45 ° C.)
  • a nonionic emulsifier such as polyoxyethylene sorbitan monolaurate or monostearate, optionally with the addition of distilled tall oil .
  • Substances with an alkaline reaction must not be added, as these will break the emulsions.
  • the cleaning power of the detergents is comparatively low, since the emulsifiers used do not make any notable contribution to the detergency. Furthermore, the stability, in particular the low-temperature stability, of the emulsions is poor, since segregation occurs below the freezing point, which cannot be easily reversed after heating.
  • liquid agents of the aforementioned type in particular in the form of highly concentrated preparations.
  • Highly concentrated agents make it possible to keep packaging, transport and storage costs low.
  • they also have the advantage of being easy to convey and dose. This not only offers decisive advantages for commercial laundries that are equipped with appropriate batch and storage tanks, but also for the z.
  • Household washing machines currently in development, equipped with storage and dosing devices. With these new devices, the detergent dosage is specifically matched to the respective washing program, which prevents undesirable or wastewater-incorrect dosing.
  • the potassium soap mentioned under (b) is derived from the fatty acids of the aforementioned composition and is preferably present in proportions of 12 to 15% by weight.
  • the ethoxylated alcohols listed under (c) are derived from native or synthetic alcohols, in particular oxo alcohols having 8 to 14, preferably 9 to 12, carbon atoms.
  • the oxo alcohols can be linearly branched or methyl-branched in the 2-position. Mixtures of native alcohols and alcohols obtained by oxo reaction are also suitable.
  • the number of ethylene glycol ether groups is on average 5 to 10, preferably 6 to 8.
  • the proportion of ethoxylated alcohols in the dispersions should be 15 to 25, preferably 18 to 22% by weight.
  • the component (d) consists of linear sodium alkylbenzenesulfonate, in particular dodecylbenzenesulfonate, in proportions of 4 to 10, preferably 6 to 8,% by weight.
  • Optical brighteners of the formula I are preferably used, in which R 1 and R 2 represent morpholino, diethanolamino or anilino residues.
  • the optical brighteners are present in proportions of 0.05 to 1, preferably 0.1 to 0.7% by weight.
  • hydrotropic compounds listed under (f) can be present in the form of the Na or K salts from urea and / or from low molecular weight alkyl or dialkylbenzenesulfonates, such as toluene, ethylbenzene, cumene or xylene sulfonate. Their proportion is preferably 1.5 to 3% by weight.
  • the component (g) consists of aliphatic C 1 -C 3 alcohols, for example ethanol, propanol and in particular isopropanol, and of the mixtures of the alcohols mentioned.
  • the content of these alcohols in the compositions is preferably up to 8% by weight.
  • Agents with fractions of less than 4% of the alcohols mentioned can also contain hydrotropic ether alcohols which are derived from C 1 -C 4 -monoalcohols and ethylene glycol or propylene glycol or diglycols.
  • hydrotropic ether alcohols which are derived from C 1 -C 4 -monoalcohols and ethylene glycol or propylene glycol or diglycols.
  • the monomethyl, monoethyl, monopropyl, monoisopropyl or monobutyl ethers of ethylene glycol are suitable.
  • the water content of the detergent concentrate is 15 to 30%, preferably up to 22% by weight.
  • the concentrates are within a temperature range between + 50 ° C and -10 ° C unlimited storage stability. Although they become pasty after storage for several weeks at a temperature of -10 ° C, they do not tend to segregate even under such extreme conditions, but instead form well-edible, largely clear liquids after reheating.
  • additives may also include biocides, fragrances, dyes, stabilizers, sequestering agents, neutral salts and optical brighteners of other constitution, but the total amount of such additives should not exceed 10% by weight and preferably less than 5% by weight, in particular less than 2 wt .-%, so that a negative influence on the cold stability is avoided.
  • component B which is combined with the dispersion described above to form fatty acid soaps before or at the start of the washing process, consists of an aqueous solution of alkalis, for example the hydroxides, carbonates, silicates, phosphates and polyphosphates of sodium or Potassium or mixtures of the alkaline compounds mentioned.
  • alkalis for example the hydroxides, carbonates, silicates, phosphates and polyphosphates of sodium or Potassium or mixtures of the alkaline compounds mentioned.
  • Their alkalinity and their amount is to be dimensioned such that the fatty acids are completely converted into the soaps and there is also an excess of alkali, so that the pH of the wash liquor is 9.5 to 14, preferably at least 10 and in particular 10.2 Is -13.5.
  • other sequestering compounds may be present, e.g.
  • Na or K salts of polycarboxylic acids, hydroxy or ether polycarboxylic acids, aminopolycarboxylic acids, hydroxyalkanephosphonic acids and aminopolyphosphonic acids examples of particularly common compounds are nitrilotriacetic acid, ethylenediaminotetraacetic acid, diethylenetriamineopentaacetic acid, 1-hydroxyethane-1,1-diphosphonic acid and 1-aminoethane-1,1-diphosphonic acid.
  • the mixing ratio of component A with liquid component B according to the above composition is 1: 1 to 1: 4, preferably 1: 2 to 1: 3, the total amount of all detergent components and washing alkalis in the washing liquor being 5 g to 30 g, preferably 10 is up to 25 g per kg of dry laundry.
  • the invention further relates to a washing process using the two components A and B in accordance with the aforementioned compositions, mixing ratios and use concentrations.
  • further components can be added, for example sodium aluminum silicates capable of cation exchange in accordance with DE-AS 2412 837, graying inhibitors, such as cellulose ethers and cellulose mixed ethers, enzymes and bleaching agents containing active oxygen or active chlorine, optionally with the addition of bleach activators.
  • graying inhibitors such as cellulose ethers and cellulose mixed ethers
  • enzymes and bleaching agents containing active oxygen or active chlorine optionally with the addition of bleach activators.
  • the stability of the compounds in question they are also preferably in the form of solutions or dispersions, it being possible, if necessary, to counteract a lack of stability by encapsulating the active compounds.
  • the fatty acids (a) used in the recipes and the fatty acids contained in the potassium soaps (b) had the following composition (in% by weight):
  • Component c An oxo alcohol of chain length C S -C 11 with 7 ethylene glycol ether groups was used as the ethoxylated alcohol (component c).
  • Component d consisted of linear Na dodecylbenzenesulfonate.
  • the sodium salt of the compound of the formula I in which R I and R 2 were morpholino radicals was used as the optical brightener (component e).
  • Urea or K-toluenesulfonate was used as the hydrotrope (component f).
  • Component g consisted of isopropanol.
  • the component “salts” means small amounts of Na 2 S0 4 and NaCl, which were present as accompanying substances of the alkylbenzenesulfonate and the optical brightener.
  • the composition is shown in Table 2.
  • the fatty acid was first mixed with the amount of potassium hydroxide solution required for soap formation as well as the ethoxylate and the alkylbenzenesulfonate, which was in the form of a 50% aqueous solution, then the optical brightener dissolved in isopropanol was stirred in, and finally the hydrotrope and water up to specified amount added.
  • the concentrates were in the form of yellowish, clear to slightly iridescent solutions which were thin at room temperature and remained clear and homogeneous when stored for three weeks in a climatic cabinet at -10 ° C and + 50 ° C. A multiple temperature change between + 50 ° C and -10 ° C also did not lead to segregation.
  • the concentrates were miscible with water in all proportions.
  • alkaline component B (amounts given in% by weight):
