Definitions

• the invention relates to a detergent and cleaning agent with 2 - 20% by weight of at least one surfactant, 5 - 30% by weight of a sodium aluminum silicate and 5 - 24% by weight of an alkali phosphate as detergent builders, and with 30 - 80% by weight of washing aids characterized in that it additionally contains 3 to 40% by weight of at least one compound selected from derivatives of hydroxylamine disulfonic acid of the formula
• nitridosulfonic acid of the formula and derivatives of imidosulfonic acid of the formula as detergent builder, where M 'is an H, Na or K atom or the NH 4 group and M is a Na or K atom or the NH 4 group.
• the washing and cleaning agent is preferably characterized by a combination of compounds according to b) and c).
• a combination of compounds according to b) and c) for example, combinations of 10-30% by weight b) and 90-70% by weight c) or even 70-90% by weight b) and 30-10% by weight c) can be used.
• M and M ' preferably denote sodium atoms.
• Known detergent builders are alkali phosphates and polyphosphates, but also the water-insoluble sodium aluminum silicates (zeolites A and X).
• sodium tripolyphosphate is preferably used as the alkali phosphate, which occupies a preferred position among the detergent builders, since it fulfills all of the aforementioned conditions, with synergistic effects in relation to the washing action in combination with detergents.
• sodium tripolyphosphate is the most important detergent builder in all mild, coarse and colored detergents.
• the content of known detergents in this builder is in the range of 25-65% by weight and in some cases even up to 90% by weight in detergents.
• the known and also the detergents according to the invention also contain various washing aids, which are often also regarded as detergent builders, e.g. B. alkali carbonates, borates, bicarbonates, silicates, nitrilotriacetic acid, citric acid, oxydiacetic acid (HOOC-CH 2 -O-CH 2 -COOH), oxydisuccinic acid, 1,2,3,4-cyclopentanetetracarboxylic acid, polyacrylic acid, polymaleic acid.
• detergent builders e.g. B. alkali carbonates, borates, bicarbonates, silicates, nitrilotriacetic acid, citric acid, oxydiacetic acid (HOOC-CH 2 -O-CH 2 -COOH), oxydisuccinic acid, 1,2,3,4-cyclopentanetetracarboxylic acid, polyacrylic acid, polymaleic acid.
• DE-AS 24 12837 detergents and bleaches for textiles are proposed in which part of the sodium tripolyphosphate has been replaced by sodium aluminum silicates.
• Such detergents see Examples 2 and 3 below
• the sodium aluminum silicates are also not the optimal solution for a detergent builder, since they only have an insufficient dispersing action and a moderate level of complexation in the washing process.
• the object of the present invention is now to overcome the disadvantages of the known builders combinations, i. H. Finding combinations that are not only more effective in their washing power, but can also be produced on the basis of easily accessible raw products.
• the detergent and cleaning agent in addition to the customary surfactants and washing aids, contain a combination of builders of alkali metal phosphates, sodium aluminum silicates and at least one compound of a derivative of hydroxylaninedisulfonic acid, nitridosulfonic acid and / or imidosulfonic acid in accordance with the introduction Contains formulas according to a), b) and c).
• the detergent and cleaning agent of the invention preferably contains anionic, zwitterionic (ampholytic) or nonionic in nature as surfactants.
• a tried and tested detergent formulation according to the invention contains, for example, dodecylbenzenesulfonate, hardened tallow soap and / or tallow fatty alcohol ethoxylated with 12 molar equivalents of ethylene oxide as surfactant.
• Washing aids include products such as the alkali or ammonium salts of sulfuric acid, silica, carbonic acid, boric acid, alkylene, hydroxyalkylene or aminoalkylenephosphonic acid as well as bleaching agents, stabilizers for peroxide compounds (bleaching agents) and water-soluble organic complexing agents.
• the bleaching agents include sodium perborate mono- or tetrahydrate, the alkali salts of peroxomcno- or peroxodisulfuric acid, the alkali salts of peroxodiphosphoric acid (H4P208).
• H4P208 the alkali salts of peroxodiphosphoric acid
• Organic complexing agents are the alkali salts of iminodiacetic acid, nitrolitriacetic acid, ethylenediaminetetraacetic acid, methylenediphosphonic acid, 1-hydroxyethane-1,1-diphosphonic acid and nitrilotrismethylenephosphonic acid.
• Washing aids that increase the dirt-carrying capacity of washing liquors, such as carboxymethyl cellulose, carboxymethyl starch, methyl cellulose or copolymers of maleic anhydride with methyl vinyl ether, foam regulators, such as mono- and dialkyl phosphoric acid esters with 16 to 20 carbon atoms in the alkyl radical, as well as optical brighteners, disinfectants and / or proteolytic enzymes additional components of the detergent and cleaning agent.
• the wash water had 18 ° dH and a pH of 10, which was adjusted by adding sodium hydroxide solution to the wash liquor.
• the washing time was 30 minutes and the liquor ratio, characterized by the ratio nis from (kg) laundry to (liter) wash liquor, 1:25 in the presence of 10 steel balls.
• the detergent dosage was 5.0 g / l in all experiments.
• the detergent had the following basic composition in all tests:
