  • the invention relates to an aqueous liquid detergent which contains hydrogen peroxide as a bleaching agent and is distinguished by good storage stability and easy meterability, and a process for its preparation.
  • non-aqueous and aqueous liquid detergents containing bleaching per-compounds are known.
  • the stabilization of the per compounds usually added as solid perhydrates or persalts is usually unproblematic.
  • stabilizing the anti-segregation agents often presents difficulties.
  • Another disadvantage is that often larger amounts of combustible organic solvents have to be added. Means of the type mentioned are described for example in DE 12 79 878 (GB 1 205 711), DE 22 33 771 (US 3 850 831), DE 28 25 218 (US 4316812) and EP 30086.
  • EP 38 101 proposes to encapsulate the bleaching agent granules and to add them to the agent in this form suspend.
  • the invention relates to a bleaching liquid detergent containing
  • (G) a solvent mixture consisting of water and of mono- or polyhydric alcohols with 2 to 6 carbon atoms.
  • Suitable alkyl sulfates (A) are the sulfuric acid monoesters of C ⁇ 2-Cl8 "fatty alcohols, such as lauryl, myristyl or cetyl alcohol, in particular the fatty alcohol mixtures obtained from coconut oil, palm and palm kernel oil and tallow, which also contain proportions of unsaturated alcohols, for example oleyl may contain alcohol.
  • this specific Gemi ⁇ in which the units of the alkyl groups to 50 to 70 wt .-% to C ⁇ 2 »to 18 to 30 wt .-% to C14, 5 to 15 wt. -% on CI ⁇ , less than 3% by weight on Cjo and less than 10% by weight on Cig
  • the proportion of fatty alkyl sulfates (A) in the agents is preferably 4 to 8% by weight in the form of the sodium salts.
  • the salts of saturated and unsaturated fatty acids having 12 to 18 carbon atoms in the form of their mixtures are preferred as soaps (B).
  • a preferred soap mixture is used, for example, from sodium oleate (B1) and the sodium salts of saturated Ci2 _ Ci6 fatty acid mixtures (B2) in a ratio of 3: 1 to 1: 3.
  • the proportion of Ci2-Ci4 fatty acids in component (B2) is expediently at least 60% by weight, preferably at least 75% by weight (calculated as fatty acid). Suitable for this are, for example, palm kernel or coconut fatty acids, from which the portions with 10 and fewer carbon atoms are largely separated.
  • oleic acid and coconut fatty acid can still contain certain proportions of stearic acid, but their proportion, based on soap-forming fatty acids, should be at most 20% by weight, preferably less than 15% by weight.
  • a soap mixture of sodium oleate (B1) and the sodium salt of lauric acid (B2) is also preferred.
  • the weight ratio of (B1) to (B2) is preferably 2: 1 to 1: 2.
  • the content of component (B) in the detergent is preferably 10 to 18% by weight (based on free fatty acid).
  • Suitable alkyl glucosides are in particular glucosides with a Cg to Cig alkyl radical, preferably with an alkyl radical consisting essentially of CIQ to CJ ⁇ , which is derived from decyl, lauryl, myristyl, cetyl and stearyl alcohol and from derives technical fractions, which preferably contain saturated alcohols.
  • the use of alkyl glucosides is particularly preferred, the alkyl radical of which contains 50 to 70% by weight of C12 and 18 to 30% by weight of C14.
  • the index number x is any number between 1 and 10. It indicates the degree of oligomerization, i.e. the distribution of monoglucosides and oligoglucosides.
  • the value x for a special product is an analytically determined arithmetic quantity, which usually represents a fractional number .
  • the average degree of oligomerization x preferably has a value of 1.1-3.0 and in particular of significantly less than 1.5. A degree of oligomerization between 1.1 and 1.4 is particularly preferred.
  • the proportion of component (C) is preferably 0.5 to 2% by weight.
  • the component (D) consists of non-ionic surfactants of the type of Anla ⁇ delay products of 5 to 10 moles of ethylene oxide with primary, preferably na- tive C j 2 ⁇ to Cig-fatty alcohols and their mixtures, such as coconut oil, tallow fatty or oleyl alcohols.
  • Ethoxylates of oxo alcohols are also suitable.
  • the proportion of fatty alcohol ethoxylates in the compositions is 8 to 18% by weight, preferably 10 to 16% by weight and in particular 12 to 14
  • the hydrogen peroxide is calculated as 100% H2O2. Its proportion is preferably 3 to 8% by weight, in particular 3.5 to 6% by weight.
  • the citric acid is preferably in the form of the sodium salt. Their proportion (based on free acid) is preferably 0.5 to 1% by weight.
  • the solvent mixture preferably contains an alcohol mixture of monohydric alcohols, such as ethanol or isopropanol, and polyhydric alcohols, such as 1,2-propanediol, butylene glycol, di- or triethylene glycol and glycerol.
  • an alcohol mixture of monohydric alcohols such as ethanol or isopropanol
  • polyhydric alcohols such as 1,2-propanediol, butylene glycol, di- or triethylene glycol and glycerol.
  • a mixture of water, methanol and 1,2-propanediol or of water, ethanol and glycerol is preferably used.
  • the ethanol content of the agent is preferably 4 to 10% by weight and in particular 5 to 7% by weight
  • the preferred proportions of polyhydric alcohol are 3 to 10% by weight and in particular 5 to 8% by weight.
  • the remainder (difference up to 100% by weight) consists of water.
  • the proportion of water is chosen so that not -gelling solutions are formed which are stable against segregation, for which generally 40 to 50% by weight, preferably 42 to 48% by weight, of water suffice ..
  • a greater dilution of the agents with water has no advantages because of the greater packaging requirement should be deionized and in particular free of heavy metal ions.
  • small amounts of those constituents which are insensitive to oxidation can be present.
  • Additional stabilizers are not -4 . required since the agents themselves have a surprisingly high storage stability.
  • small amounts, ie a maximum of 1% by weight, of stabilizers which are insensitive to oxidation can be present, for example phosphonates such as l-hydroxyethane-l, l-diphosphonate, ethylenediamine-tetra- (methylenephosphonate) and diethylenetriamine-penta- ( methylene phosphate), in each case in the form of the Na or K salt, or alkylphenols such as 2,6-di-tertiary-butyl-4-methylphenol.
  • Phosphonates are preferably used in Amounts of 0.5 to 1% by weight and 2,6-di-tert-butyl-4-methylphenol are used in amounts of 0.005 to 0.1% by weight and in particular 0.005 to 0.05% by weight .
  • the pH of the compositions is adjusted to 6.8 to 7.7, preferably 7.0 to 7.5.
  • the agents are stable in storage even in the absence of stabilizers and hydrotopes.
  • the loss of active oxygen is less than 3% even after two months of storage at room temperature (25 ° C).
  • they are distinguished by a high washing and bleaching effect, in particular in relation to colored soiling.
  • the invention further relates to a method for producing the liquid detergents described above.
  • the liquid detergents can be produced in a manner known per se.
  • the oleic acid and the C12- to Ci ⁇ -fatty acid or the Ci2-Ci6-fatty acid mixture and citric acid are first in a pre-heated to 50 - 80 ° C mixture containing deionized water, sodium hydroxide and 1,2-propanediol Stirred dissolved and transferred to their salts.
  • the remaining components of the liquid detergent can be added in any order.
  • the alkyl sulfate is advantageously added before the addition of alkyl glucoside and fatty alcohol ethoxylate. After cooling the solution to temperatures below 30 ° C., the ethanol and the hydrogen peroxide are added, the latter being usually used as a 25% aqueous hydrogen peroxide solution.
  • liquid detergents contained the components listed in Table 1, the individual means:
  • the clear liquid detergents were easy to pour.
  • the agent according to example 1 After storage for 8 weeks at room temperature (25 ° C.), the agent according to example 1 had a loss of active oxygen (starting content - 100% calculated) of 2.2%, in example 2 of 2.1% and in example 3 of 1.9%.
  • the agent according to Example 1 When stored at 40 ° C. for 8 weeks, the agent according to Example 1 had a loss of active oxygen of 13%, in Example 2 of 12.5% and in Example 3 of 5.7%.
