Definitions

  • the present invention relates to low-foaming liquid preparations for Washing of textiles, the tensides of which are largely made from renewable raw materials.
  • Liquid detergents today mainly consist of anionic surfactants, especially alkylbenzenesulfonate, Fatty alcohol oxyethylate and soap, whereas washing powder in addition to the surfactants alkyl benzene sulfonate and fatty alcohol oxyethylate as essential active ingredients, builder substances, bleaching agents and other electrolytes contain.
  • anionic surfactants especially alkylbenzenesulfonate, Fatty alcohol oxyethylate and soap
  • washing powder in addition to the surfactants alkyl benzene sulfonate and fatty alcohol oxyethylate as essential active ingredients, builder substances, bleaching agents and other electrolytes contain.
  • surfactants in particular those based on petrochemicals are used.
  • the object of the invention was therefore to provide a surfactant combination for low-foaming detergents find that are largely made from renewable raw materials that are exceptionally organic are degradable and achieve very good washing results.
  • the invention therefore relates to a low-foaming, liquid machine washing detergent, which is characterized in that the surfactant component consists of 5 to 30% alkyl polyglycoside, 5 to 30% fatty alcohol ether carboxylate, 5 to 30% soap and 0 to 3% other surfactants consists.
  • alkyl polyglycoside in combination with anionic surfactants is known. So DE-OS 593 422 already mentions the washing effect-enhancing effect of alkyl glycoside in soaps. Later documents such as EP-A 0 075 994, 0 105 556, 0 199 765 or DE-OS 37 02 286 describe the Use of alkyl polyglycosides in combination with a number of known anionic surfactants in detergents. The most important in terms of quantity is the most important surfactant, alkylbenzenesulfonate.
  • Other components are other surfactants in small quantities, complexing agents, bleaching agents, optical brighteners, graying inhibitors, Corrosion inhibitors, foam regulators, stabilizers, enzymes, enzyme stabilizers, Electrolytes, hydrotropic substances, solubilizers, etc.
  • Alkyl polyglycosides used according to the invention satisfy formula I.
  • RON n in which R represents a linear or branched, saturated or unsaturated aliphatic alkyl radical having 10 to 18 carbon atoms or mixtures thereof and Z n represents a polyglycosyl radical with n 1.0 to 3 hexose or pentose units or mixtures thereof.
  • Alkyl polyglycosides with fatty alkyl radicals having 10 to 16 carbon atoms and one are preferred Polyglycosyl radical from n 1.1 to 2. Alkylpolyglucosides are particularly preferred.
  • the alkyl polyglycosides used according to the invention can be based on known processes renewable raw materials are produced. For example, dextrose is in the presence of an acid Catalyst with n-butanol converted to butyl polyglycoside mixtures, which with long-chain alcohols also glycosidated in the presence of an acid catalyst to give the desired alkyl polyglycoside mixtures become. Or 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 selected of long chain alcohol.
  • the industrially accessible ones are favorable for economic reasons
  • Ziegler alcohols or oxo alcohols can also be used.
  • the polyglycosyl radical Z n is 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 are always mixtures of oligomers, which in turn represent mixtures of different isomeric forms. They are side by side with ⁇ - and ⁇ -glycosidic bonds in pyranose and furanose form. The junctions between two Saccachrid residues are also different.
  • Alkyl polyglycosides used according to the invention can also be mixed by mixing alkyl polyglycosides with alkyl monoglycosides.
  • the latter can e.g. B. according to EP-A 0 092 355 by means of polar Obtain or enrich solvents, such as acetone, from alkyl polyglycosides.
  • the degree of glycosidation is expediently determined by means of 1 H-NMR.
  • the detergents according to the invention contain 5 to 30% alkyl polyglycoside, preferably 7 to 20%.
  • the alkyl polyglycosides Compared to almost all other surfactants used in detergents, the alkyl polyglycosides apply as extremely environmentally friendly. So lies the one determined by means of a sewage treatment plant simulation model / DOC analysis degree of biodegradation for the alkyl polyglycosides according to the invention at 96 ⁇ 3%. That number is before Background to see that with this test method (total degradation) already a degree of degradation> 70% Substance indicated as readily degradable.
  • the acute oral toxicity LD 50 (rat) with> 10,000 mg / kg and the aquatic toxicity LC 50 (Gold orfe) with approx. 12 mg / l and EC 50 (daphnia) with 30 mg / l are cheaper by a factor of 3 to 5 than that corresponding values of the most important surfactants today. The same applies to skin and mucous membrane compatibility.
  • Fatty alcohol ether carboxylates are compounds of either formula II (R'-O (CH 2 -CH 2 -O) x CH 2 COO) m M m + in which R 'is a linear or branched, saturated or unsaturated alkyl radical having 8 to 22, preferably 10 to 18, carbon atoms, x 1 to 40, preferably 3 to 30, m 1 or 2 and M hydrogen, alkali, alkaline earth metal, ammonium or alkanolammonium is, or III ([R "-O (CH 2 -CH 2 -O) y ] 2 CHCOO) z N z + in which R "is a linear or branched, saturated or unsaturated alkyl radical having 8 to 22, preferably 10 to 18, carbon atoms, y 1 to 40, preferably 3 to 30, z 1 or 2 and MH, alkali, alkaline earth metal, ammonium or alkanolammonium ,
  • the carboxymethylated oxethylates can be according to DE-OS 24 18 444 or EP-A 0 106 018 by reacting oxethylates of the formula R'-O (CH 2 -CH 2 -O) n H with chloroacetic acid or a salt of chloroacetic acid in the presence of alkali hydroxide or other bases. But other manufacturing processes such. B. by means of catalytic oxidation according to EP-A 0 018 681 or 0 039 111 are suitable.
  • Corresponding alcohols for the production of the fatty alcohol ether carboxylates are preferably fatty alcohols or Ziegleral alcohols, in exceptional cases also oxo alcohols.
  • the one following the oxethylation Carboxymethylation can be complete if the procedure is appropriate, so that the fatty alcohol ether carboxylates are purely anionic surfactants.
  • the carboxymethylation is incomplete, they contain Products certain amounts of unreacted oxyethylate. With formulas II and III is therefore usually a Mixture with different amounts of unreacted oxethylates meant. Accordingly, define a degree of implementation. A degree of conversion between 70 and 100% is preferred.
  • the fatty alcohol ether carboxylates are also very environmentally friendly surfactants. So using a sewage treatment plant simulation model / DOC analysis biodegradation rates found above 90%.
  • the acute oral Toxicity LD 50 (rat) and aquatic toxicity LC 50 (gold orfe) are about as favorable as that the alkyl polyglucoside. The same applies to skin and mucous membrane compatibility.
  • the detergents according to the invention contain 5 to 30% fatty alcohol ether carboxylates, which also include mixtures could be. A content of 7 to 20% fatty alcohol ether carboxylate is preferred.

  • builders should be mentioned as non-surfactant components.
  • water-soluble builders such as different polyphosphates, phosphonates, carbonates, polycarboxylates, Citrates, polyacetates such as NTA and EDTA etc. or their mixtures. These connections will be usually used as alkali salts, preferably as sodium salts. Although not complex, too To mention sodium sulfate here.
  • Builders such as aluminosilicates of suitable particle size (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 are also optionally combined with bleach activators such as tetraacetylethylene diamine etc. or percarbonate; of course also come into question other bleaching agents (cf. K. Engel, Tenside Surfactants 25, p. 21 (1988).
