Definitions

  • 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 flammable organic solvents have to be added.
  • DE-A-10 80 722 proposes adding highly condensed phosphates to the agents and adjusting them to a pH of 6 to 6.5. Due to the phosphate content, the agents in the wastewater have a eutrophic effect. In addition, because of their high proportion of nonionic surfactants, the compositions are pasty and therefore, as preferred in consumer circles, cannot be metered with measuring cups.
  • the agents described in DE-A-15 67 583 (US-A-3,658,712) contain a special cross-linked polymer as a stabilizer, which also makes the agents very viscous and therefore difficult to dose.
  • EP-A-86 511 it is proposed to use a mixture of fatty acids and soluble calcium salts to stabilize H2O2 in liquid detergents.
  • EP-A-38 101 proposes to encapsulate the bleach granules and to suspend them in this form in the composition. There is no information in the document about the type of capsule material, which logically has to be stable or insoluble in the aqueous stock concentrate, but has to be inconsistent or slightly soluble in the aqueous wash liquor.
  • Suitable alkyl sulfates (A) are the sulfuric acid monoesters of C12-C18 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 additionally contain proportions of unsaturated alcohols, for example oleyl alcohol, can contain.
  • Mixtures in which the proportions of the alkyl radicals are 50 to 70% by weight to C12 find a preferred use 18 to 30% by weight of C14, 5 to 15% by weight of C16, less than 3% by weight of C10 and less than 10% by weight of C18 are distributed.
  • the proportion of fatty alkyl sulfates (A) in the compositions 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 C12-C16 fatty acid mixtures (B2) in a ratio of 3: 1 to 1: 3.
  • the proportion of C12-C14 fatty acids in component (B2) is advantageously 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 the component (B) is preferably 10 to 18% by weight (based on free fatty acid).
  • alkyl glucosides (C) are the glucosides with a C8 to C18 alkyl radical, preferably with an alkyl radical consisting essentially of C10 to C16, which is derived from decyl, lauryl, myristyl, cetyl and stearyl alcohol and from derives technical fractions, which preferably contain saturated alcohols. It is particularly preferred to use alkyl glucosides whose alkyl radical 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 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.
  • Component (D) consists of nonionic surfactants of the type of adducts of 5 to 10 moles of ethylene oxide with primary, preferably native C12 to C18 fatty alcohols and their mixtures, such as coconut oil, tallow oil or oleyl alcohols. Ethoxylates of oxo alcohols (according to the method of Oxosynthesis or hydroformylation of 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% by weight.
  • 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, ethanol 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.
  • polyhydric alcohol the preferred proportions are 3 to 10% by weight and in particular 5 to 8% by weight.
  • the rest (difference up to 100% by weight) consists of water.
  • the proportion of water is chosen so that non-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 are sufficient.
  • a greater dilution of the agents with water has no advantages because of the greater packaging requirements.
  • the water is said to be deionized and, in particular, to be free of heavy metal ions.
  • oxidation-insensitive stabilizers for example phosphonates such as 1-hydroxyethane-1,1-diphosphonate. Ethylene diamine tetra (methylene phosphonate) and diethylene triamine penta- (methylene phosphonate), each 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 generally set 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 characterized by a high washing and bleaching effect, especially in relation to colored stains.
  • 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 C16 fatty acid or the C12-C16 fatty acid mixture and citric acid are first dissolved in a preheated to 50 - 80 ° C mixture containing deionized water, sodium hydroxide and 1,2-propanediol, with stirring and converted into 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.
  • the clear liquid detergents were easy to pour.
  • 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%.
