Definitions

  • the respective demand for the base liquor is carried out via the automatically controlled washing program.
  • the flawless functioning of such a base liquor system may include a. ahead that the detergent ingredients are either completely dissolved in the alkali or at least finely divided in the floating state. Both the stopping and the creaming of water-insoluble constituents pose a danger to the automatic dosing, because a clogging of the line system of the plant caused thereby can cause considerable disturbances in the entire washing process.
  • detergents that contain small amounts of water-insoluble, very fine-particle magnesium silicate are also designated as base liquors. Obviously, such small quantities do not cause any problems, as there have been exceptions so far and the powder detergents used could be used without any problems.
  • detergent slurries are known, which can also contain up to 30 wt .-% sodium aluminum silicate.
  • these stabilized suspensions contain a combination of a water-dispersible, crosslinked copolymer made from an acrylic acid and a polyester of a polyol on the one hand and sodium polyacrylate on the other.
  • These detergent slurries are obtained by carefully stirring the individual components into the water provided in a specific order.
  • These products are relatively low-water, viscous suspensions; However, their complicated manufacture makes them uninteresting for use in large laundries because the specialist is used to making the master liquor from one Make powder detergent by stirring in water and not by diluting a suspension.
  • a base liquor is the dilute aqueous solution or suspension of a detergent, so that the known teachings on the preparation of concentrated suspensions do not readily apply the preparation of dilute suspensions are applicable.
  • none of the stabilizers described for concentrated sodium aluminum silicate suspensions has been suitable for the stabilization of a stock solution containing sodium aluminum silicate.
  • xanthan gum proved to be a dispersing agent which was added as an additive in quantities of 0.5 to 2.5% by weight to powdered heavy-duty detergents containing 10 to 40% by weight of water-insoluble alkali aluminum silicate Exclusive detergents, which can be traded and sold as such and which, like the previously known tripolyphosphate-based agents, can be used without problems in master liquor systems and can be converted to about 10% alkalis.
  • the present invention therefore relates to pulverulent, base-leachable, alkaline-reacting detergents and cleaners containing synthetic surfactants, alkali aluminum silicates and preferably further constituents from the group of alkali carbonates, alkali silicates, alkali sulfates, water-soluble organic or inorganic complexing agents, optical brighteners and smaller amounts of other customary ones
  • Additives which are characterized in that they contain a) 10 to 40, preferably 15 to 25% by weight finely divided zeolites of the NaA or NaX type or mixtures thereof, and b) 0.5 to 2.5, preferably 1.0 to Contain 2.0% by weight of xanthan gum, the weight ratio of a: b being 5: 1 to 25: 1, preferably 10: 1 to 20: 1, and which can be obtained by mixing with water to about 10% by weight.
  • the invention further relates to the use of b) 0.5 to 2.5% by weight of xanthan gum, based on the total weight of the dry washing and cleaning powder containing a) 10 to 40% by weight of NaA or zeolites NaX or mixtures thereof, also based on the dry powder, as a dispersant additive for the preparation of 10% by weight aqueous stable stock liquor suspensions, the ratio of a: b being 5: 1 to 25: 1.
  • Xanthan gum here is based on Römpps Chemie-Lexikon, 7th edition (1973), pages 1355 and 1356, a product that is known under the Anglo-Saxon name “Xanthan gum”.
  • Xanthan gum is a high molecular weight polysaccharide, i.e. H. an exocellular heteropolysaccharide derived from various types of Xanthomonas, e.g. B. Xanthomonas campestris is produced. They are hydrophilic colloids. Numerous publications deal with their production by aerobic propagation and cultivation of bacteria of the genus Xanthomonas in aqueous nutrient media. The basic work is described in US Pat. No. 3,000,790.
  • hydrophilic colloids produced by Xanthomonas campestris are polysaccharides that contain mannose, glucose, glucuronic acid, 0-acetyl residues and acetyl-linked pyruvic acid. They arise as an exocellular reaction product of the bacteria types mentioned when they are aerobically grown in aqueous nutrient solutions which, in addition to the usual growth-promoting components, in particular contain water-soluble carbohydrate compounds as a carbon source. In practice, glucose in particular is used as the source of assimilable carbon.
  • Examples of synthetic surfactants are anionic surfactants of the sulfonate type, such as alkylbenzenesulfonates (C 8-15 -alkyl), olefin sulfonates, ie mixtures of alkene and hydroxyalkanesulfonates and disulfonates, such as those obtained from C 12 -C 18 monoolefins with a terminal or internal double bond obtained by sulfonation with gaseous sulfur trioxide and subsequent alkaline or acidic hydrolysis of the sulfonation products.
  • anionic surfactants of the sulfonate type such as alkylbenzenesulfonates (C 8-15 -alkyl), olefin sulfonates, ie mixtures of alkene and hydroxyalkanesulfonates and disulfonates, such as those obtained from C 12 -C 18 monoolefins with a terminal or internal double bond obtained by sulf
  • alkanesulfonates which are obtainable from C 12 -C 18 -alkanes by sulfochlorination or sulfoxidation and subsequent hydrolysis or neutralization or by bisulfite addition to olefins, and the esters of ⁇ -sulfofatty acids, e.g. B. the a-sulfonic acids from methyl or ethyl esters of hydrogenated coconut, palm kernel or tallow fatty acids.
  • Suitable anionic surfactants of the sulfate type are the sulfuric acid monoesters of primary aliphatic C 10 -C 20 -alcohols (e.g. from coconut fatty alcohols, tallow fatty alcohols or oleyl alcohol) and those of secondary aliphatic C 10 -C 20 alcohols. Also suitable are sulfated fatty acid alkanolamides, fatty acid monoglycerides with C 10 C2o fatty acids and the sulfates of the primary or secondary aliphatic C 10 -C 20 alcohols reacted with 1-6 mol ethylene oxide.
  • surfactants with anionic groups can be in the form of their sodium, potassium and ammonium salt and as soluble salts of organic bases, such as mono-, di- or triethanolamine.
  • Suitable surfactants are also nonionic surfactants, primarily the adducts of 7-20 moles of ethylene oxide which are practically water-soluble at room temperature, with 1 mole of an aliphatic C 10 -C 20 alcohol, or an alkylphenol, fatty amine or a fatty acid.
  • the ethoxylation products of the aliphatic alcohols in particular the coconut or tallow fatty alcohols, the oleyl alcohol, the C 10 -C 20 oxo alcohols and the secondary aliphatic alcohols with essentially 12-18 C atoms are particularly important.
  • nonionic surfactants are also the fatty acid alkanolamides, such as. B. the compounds coconut or tallow fatty acid ethanolamide and diethanolamide, oleic acid diethanolamide etc.
  • the useful nonionic surfactants also include the surface-active amine oxides, which are usually derived from tertiary amines with a hydrophobic C 10 -C 20 alkyl group and two shorter alkyl and / or alkylol groups each containing up to 4 C atoms.
  • Typical representatives are, for example, the compounds N-dodecyl-N, N-dimethylamine oxide, N-tetradecyl-N, N-dihydroxyethylamine oxide or N-hexadecyl-N, N-bis (2,3-dihydroxypropyl) amine oxide.
  • the water-soluble organic or inorganic complexing agents for calcium can be found at the polycarboxylic acids, hydroxycarboxylic acids, aminocarboxylic acids, carhoxyalkyl ethers, polyanionic polymeric carboxylic acids, phosphonic acids and the polyphosphoric acids, these compounds mostly being used in the form of their water-soluble salts.
  • citric acid carboxymethyltartronic acid, mellitic acid, polyacrylic acid, poly-a-hydroxyacrylic acid, carboxymethyl malic acid, nitrilotriacetic acid, 1-hydroxy-ethane-1,1-di-phosphonic acid and the alkali metal pyrophoaphates, tripolyphosphates as well as the alkali metal salts and higher polyphosphorus phosphorus.
  • alkalis such as alkali metal silicates, in particular alkali metal silicates and inorganic fillers such as sodium carbonate or sodium sulfate; small amounts may also be present, for example, of dirt carriers which suspend the dirt detached from the fibers in the liquor and so on prevent graying.
  • water-soluble colloids of mostly organic nature are suitable, such as, for example, the water-soluble salts of polymeric carboxylic acids, glue, gelatin, salts of ether carboxylic acids or ether sulfonic acids of starch or cellulose such as carboxymethyl cellulose or methyl cellulose, in particular their mixtures or salts of acidic sulfuric acid esters of cellulose or starch.
  • polyamides containing acid groups are suitable for this purpose.
  • Soluble starch preparations and starch products other than those mentioned above can also be used, e.g. B. degraded starch, aldehyde starches, etc.
  • Polyvinylpyrrolidone is also useful.
  • Corrosion inhibitors also belong to the other usual constituents of the agents according to the invention.
  • the constituents of the powder detergents were mixed in a Lödige mixer.
  • Xanthan gum and fragrances were mixed in recently.
  • the water- and temperature-stable components can also be processed into a so-called slurry and sprayed as a mixture.
  • the powder obtained is then also mixed with xanthan gum and fragrances.
  • the following tables show 15 examples of detergents according to the present invention, which led to powder detergents which can be used as base lye.
  • EO means ethylene oxide and e.g. B. "8 EO” the adduct of 8 moles of ethylene oxide to the immediately preceding compound.
  • Kelzan ® from Kelco Comp. used.
  • a finely divided zeolite NaA produced by industrial processes can contain minor amounts of zeolite NaX or zeolite HS which do not impair the builder properties. Such zeolite mixtures can be used according to the invention with the same success. Zeolite NaX instead of NaA is also suitable. Due to the manufacturing process, the crystalline zeolites can also contain the X-ray amorphous preforms of similar composition in insignificant amounts.
  • Example 5 Comparative examples to Example 5 with (a) sodium polyacrylate (pigment distributor N from BASF) and (b) purified sodium carboxymethyl cellulose (Relatin 7000 P from Henkel KGaA):
