Definitions

  • the present invention relates to powdered preparations for washing textiles, the surfactants of which are largely produced from renewable raw materials.
  • Powder detergents produced either by spray drying or agglomeration processes, today consist of surfactants, builders, bleaches and additives in smaller quantities such as optical brighteners, graying inhibitors, corrosion inhibitors, foam regulators, stabilizers, possibly odorants, dyes etc.
  • the surfactant component is usually in the foreground, usually a combination of anionic and nonionic surfactants, the essential basis of which is petroleum today.
  • the object of the invention was therefore to find a surfactant combination for powdered detergents which are largely made from renewable raw materials and which are extremely biodegradable, these powders having to achieve very good washing results.
  • This object was achieved by a surfactant combination consisting of alkyl polyglycosides with a degree of glycosidation ⁇ 1.4 as well as fatty alcohol oxyethylates, anionic surfactants and soap.
  • alkyl polyglycosides in combination with fatty alcohol oxyethylates, in the presence of anionic surfactants in small amounts, achieve very good washing results in the powder mixtures according to the invention.
  • alkyl polyglycoside in combination with anionic and nonionic surfactants is described in European applications EP-0 075 994, EP-0 075 995 and EP-0 075 996; here the degree of glycosidation is G ⁇ 1.5.
  • Alkyl polyglucosides are particularly preferred.
  • the alkyl polyglycosides used according to the invention can be produced by known processes based on renewable raw materials.
  • dextrose is reacted with n-butanol to give butylpolyglycoside mixtures in the presence of an acidic catalyst, which are transglycosidated with long-chain alcohols in the presence of an acidic catalyst to give the desired alkylpolyglycoside mixtures.
  • dextrose is immediately reacted with the desired long-chain alcohol.
  • the structure of the products can be varied within certain limits.
  • the alkyl radical R is determined by the choice of the long-chain alcohol.
  • the industrially accessible alcohols with 8 to 18 carbon atoms, in particular native alcohols from the hydrogenation of carboxylic acids or carboxylic acid derivatives.
  • Ziegler alcohols or oxo alcohols can also be used.
  • the polyglycosyl radicals Z n are determined, on the one hand, by the selection of the carbohydrate and, on the other hand, by setting the average degree of polymerization n z. B. according to DE-OS 19 43 689.
  • polysaccharides e.g. B. starch, maltodextrins, dextrose, galactose, mannose, xylose, etc.
  • the industrially available carbohydrates starch, maltodextrins and especially dextrose are preferred.
  • Alkyl polyglycosides used according to the invention can also be prepared by mixing alkyl polyglycosides with alkyl monoglycosides.
  • the latter can e.g. B. according to EP-A 0 092 355 using polar solvents, such as acetone, from alkyl polyglycosides.
  • the degree of glycosidation is advantageously determined by means of 1 H-NMR.
  • the detergents according to the invention contain 2 to 18% alkyl polyglycoside, preferably 3 to 15%.
  • the alkyl polyglycosides are considered to be extremely environmentally compatible.
  • the degree of biodegradation for the alkyl polyglycosides according to the invention determined by means of a sewage treatment plant simulation model / DOC analysis, is 96 ⁇ 3%. This figure can be seen against the background that with this test method (total degradation) a degree of degradation ⁇ 70% already indicates the substance to be readily degradable.
  • the acute oral toxicity LD 50 (rat) with> 10,000 mg / kg as well as the aquatic toxicity LC 50 (gold orfe) with approx. 12 mg / l and EC 50 (daphnia) with 30 mg / l are by a factor of 3 to 5 cheaper than the corresponding values of today's most important surfactants. The same applies to skin and mucous membrane compatibility.
  • the compounds are generally made by addition of ethylene oxide onto longer-chain alcohols in the presence of basic or acidic Catalysts made.
  • basic or acidic Catalysts made.
  • commercially available alcohols with 8 to 22 carbon atoms from the hydrogenation of carboxylic acids or carboxylic acid derivatives are favorable.
  • Ziegler alcohols or oxo alcohols can also be used.
  • the alcohol oxyethylates are known to be readily biodegradable; Their data are also favorable with regard to aquatoxicity, skin and mucous membrane compatibility.
  • the liquid detergents according to the invention contain 2 to 18% fatty alcohol oxyethylates, which can also be mixtures. Contents of 3 to 15% by weight are preferred.
  • Anionic surfactants :
  • Anionic surfactants used are alkylbenzene sulfate, alkane sulfonates, olefin sulfonates, fatty alcohol sulfates and fatty alcohol ether sulfates or their mixtures having 9 to 20 carbon atoms in the alkyl or alkylene group. Na, K, NH4, Mg and their mixtures are the counterions. These anionic surfactants, which can be present in the mixtures according to the invention in amounts of 0 to 12% by weight, are not to be understood as soap. Amounts of 1 to 10% by weight are preferred.
  • Fatty acid salts or their acids according to the invention correspond to formula III R '''COOP III, in which R '''is a saturated or unsaturated alkyl radical having 8 to 22 carbon atoms and P is hydrogen, alkali, ammonium or alkanolammonium.
  • the detergents according to the invention contain 0.5 to 30% soap, which will usually be a mixture of different components. Contents of 1 to 25% are preferred.
  • builders should be mentioned as non-surfactant components.
  • water-soluble builders such as different polyphosphates, phosphonates, carbonates, polycarboxylates, citronates, polyacetates such as NTA and EDTA etc. or mixtures thereof are used. These compounds are usually used as alkali salts, preferably as sodium salts. Although not complexing, sodium sulfate should also be mentioned here.
  • water-insoluble builders such as aluminosilicates of suitable particle size, is also according to the invention (cf. EP-A 0 075 994).
  • the concentration of the builders in the detergent is 0 to 70%, preferably 0 to 50%.
  • Bleaching agents such as sodium perborate, optionally combined with bleach activators such as tetraacetylethylene diamine etc. or percarbonate, are also used according to the invention; Other bleaching agents are of course also possible (cf. K. Engel, Tenside Surfactants 25, S. (1988).
  • concentration of the bleaching agents is 0 to 40%, preferably 0-30%.
  • Adjusting agents such as low molecular weight mono- or dihydric alcohols, alkyl ethers of polyhydric alcohols, hydrotropics such as alkylbenzenesulfonates with 1 to 3 carbon atoms in the alkyl radical, alkanolamines or urea, enzymes such as in particular proteases and enzyme stabilizers, corrosion inhibitors such as alkali silicates, optical, may be used according to the invention

  • the liquid components were added to the mixture of solid components in small portions with intensive stirring. Stirring ensures sample homogeneity.
  • the known methods were used to characterize the powders in terms of bulk density and angle of repose.
  • the washability was determined in a normal household washing machine, and the foam development was also checked.
