Definitions

  • Textile detergents to be used in commercial laundries differ considerably in their composition from those which are usually used in the household.
  • softened, ie Ca and Mg-free water is used regularly in commercial companies.
  • the commercially used agents often contain highly alkaline builder salts and alkalis, such as sodium metasilicate and sodium hydroxide, which can be handled safely by a person skilled in the art, but are unsuitable in the household for safety reasons.
  • These highly alkaline constituents can in turn interact with the surfactants usually present, in particular the nonionics from the class of the alkyl polyglycol ethers, and more or less decompose them if they are stored together for a long time.
  • surfactants which are made from natural, i.e. renewable raw materials are available and are characterized by their complete and rapid biodegradability in wastewater.
  • Highly alkaline cleaner concentrates for the industrial cleaning of metallic surfaces were known from EP-A-282 863. These agents contain 80 to 99.7 wt .-% of an aqueous solution of a builder mixture of alkali metal silicates and alkali metal hydroxides and 0.3 to 20 wt .-% of a surfactant combination of anionic surfactants, alkyl glucosides and other nonionic surfactants, with amounts of 0.1 to 10% by weight of alkyl glucosides and 0.1 to 5% by weight of nonionic surfactants in combination with 0.1 to 5% by weight of fatty acids or soaps are preferred.
  • EP-A-202 638 describes liquid cleaning agents for strongly alkaline cleaning formulations. These surfactant concentrates, which contain nonionic surfactants and alkyl glucosides, but no alkaline builder substances, are only mixed with alkaline builder substances during practical use.
  • WO-A-87/06949 further describes a liquid detergent which contains alkyl glucosides and builder substances which have a particular solubility. The solubility of relatively poorly soluble builder substances is supported by the use of alkyl glucosides.
  • R is preferably a C8 ⁇ 12 alkyl radical, in particular a C8 ⁇ 10 alkyl radical.
  • the alkyl glucosides can still contain small amounts of free fatty alcohol and glucose in their production. Those alkyl glucosides are preferably used whose content of fatty alcohols is less than 5% by weight, in particular less than 2% by weight (based on alkyl glucoside).
  • the agents can optionally also contain nonionic surfactants of the ethoxylated fatty alcohol and oxo alcohol type with 12 to 18 carbon atoms and 5 to 10 ethylene glycol ether groups (EO).
  • EO ethylene glycol ether groups
  • Suitable are e.g. Ethoxylates derived from coconut, tallow or palm kernel fatty alcohols with an HLB value of more than 12, for example from 13 to 18, and corresponding ethoxylates from oxo alcohols with 12 to 16 carbon atoms and 6 to 8 EO groups.
  • the builder component consists of sodium hydroxide (component B1), sodium silicate (component B2) and sequestering polyanionic salts derived from nitrilotriacetic acid (NTA) and possibly phosphonic acids (components B3 and B4).
  • the Na2O: SiO2 ratio can be 1: 1 (metasilicate) to 1: 3.4 (water glass).
  • metasilicate is preferably used in agents with a low proportion of sodium hydroxide, while in agents with a higher sodium hydroxide content the sodium silicate can consist predominantly or entirely of water glass.
  • the NTA is available as a trisodium salt and is also used in this form of quantity calculation. In particular, its proportion is 5 to 10% by weight.
  • the sodium salt of 1-hydroxyethane-1,1-diphosphonic acid is primarily suitable as the phosphonate.
  • the quantity calculation is based on the tetrasodium salt.
  • the sodium salts of aminotrimethylenephosphonic acid (ATMP), ethylenediaminetetramethylenephosphonic acid (EDTMP), diethylenetriaminepentamethylenephosphonic acid (DTPMP) and their higher homologs are also usable. unexplained function in wastewater less preferred.
  • Your quantity calculation is based on neutral reacting sodium salts (Na3 salt with ATMP, Na5 salt with EDTMP, Na6 salt with DTPMP).
  • the sum of components B3 + B4 is 3 to 12% by weight, preferably 6 to 11% by weight.
  • the detergents can also contain conventional detergent constituents which do not act as surfactants and builders. These include optical brighteners in proportions of up to 1% by weight, preferably 0.05 to 0.3% by weight. Examples of these are derivatives of bis (triazinylamino) stilbene disulfonic acid, for example the sodium salt of 4,4'-bis (2-anilino-4-morpholino-1,3,5-triazin-6-yl-amino) -stilbene-2,2'-disulfonic acid and the chlorinated diphenyldistyrylsulfonic acids.
  • optical brighteners in proportions of up to 1% by weight, preferably 0.05 to 0.3% by weight. Examples of these are derivatives of bis (triazinylamino) stilbene disulfonic acid, for example the sodium salt of 4,4'-bis (2-anilino-4-morpholino-1,3,5-triazin-6-yl-amino) -stilbene-2,2'-disulfonic acid and the
  • hydrotropes are e.g. Toluene sulfonate, xylene sulfonate and cumene sulfonate, each in the form of the sodium salts.
  • Usable solvents are, for example, ethanol, propanol, isopropanol and ether alcohols, such as diglycol and C1-C3 monoalkyl ethers of C2-C4 diols.
  • the hydrotropes can be present in proportions up to 6% by weight, the alcohols or ether alcohols in proportions up to 10% by weight.
  • the agents can also contain neutral salts, such as sodium sulfate and sodium chloride, as minor substances in the raw materials used. The difference of up to 100% by weight is water.
  • the agents are long-lasting, pourable liquids that are suitable for automatic dosing as well as for the preparation of stock solutions (base liquors).
  • the concentrates are still liquid down to temperatures of -10 ° C and are resistant to segregation.
  • Their application concentration is generally 2 to 10, preferably 3 to 7 g / l.
  • the amount of laundry was 7.5 kg, the water hardness 0 ° dH, normal program (without prewash), detergent concentration 4 g / l, 5 minutes at 40 ° C and 15 minutes at 90 ° C, three rinsing, low foaming.
