Definitions

• the present invention relates to a washing additive which can be added to washing liquors to increase the washing effect.
• the addition of the additive according to the invention improves the removal of bleachable soiling and of grease / oil and pigment soiling from the textiles to be washed.
• the washing liquor When washing textiles, the washing liquor is generally heated to a temperature which is higher than room temperature. This measure significantly increases the washing performance of the detergents used. However, heating the washing liquor and the textiles is associated with increased energy expenditure during washing.
• some textiles, in particular textiles made of wool or synthetic fibers cannot be washed at elevated temperature for various reasons, attempts have repeatedly been made to achieve good washing results when washing at low temperatures. At low washing temperatures, however, the effect of the per compounds frequently used to remove bleachable stains is in some cases considerably reduced or even weakened to the extent that such stains can no longer be removed. For this reason, detergents are added to increase the bleaching effect, so-called bleach activators, which increase the bleaching effect of the per compounds and allow the effect to be used even at lower washing temperatures.
• DE-OS 27 44 642 describes a detergent additive which contains an organic bleach activator in water-releasable combination with a non-particulate substrate.
• the detergent additive of DE-OS 27 44 642 can also contain other additives, such as. B.
• foam modifiers By separating the bleach activator and the bleaching per-compound bi immediately before use, the problems that bj the joint storage of per-compounds and bleach activators can ent stand, be avoided.
• a further improvement in the washing performance of detergents based on anionic surfactants and inorganic persalts is made possible by an additive which, according to the teaching of DE-OS 28 57 153, in addition to a bleach activator, is a combination of an alkoxylated nonionic surfactant and a cationic surfactant with 8 to 20 carbon atoms containing residue and otherwise short residues with 1 to 4 carbon atoms on a substrate.
• a disadvantage of the additives mentioned is that the user of these additives comes into contact with the active ingredients when the additives are removed from the packaging and when the additives are added to the detergent liquor, which, apart from a sometimes unpleasant feeling, can lead to skin irritation.
• Another disadvantage of the additives mentioned is that after washing, the water-insoluble substrate has to be sorted out from the washed textiles.
• the aim of the present invention is therefore to provide a washing additive for increasing the washing performance of detergents, in which the user does not come into contact with the active ingredients of the additive and whose substrate does not need to be sorted out from the washed textiles after washing.
• Addition products of ethylene oxide with fatty alcohols or, in particular, oxo alcohols, which have 12 to 18, preferably 14 to 15, carbon atoms are particularly suitable as nonionic surfactants.
• the best effects are achieved with oxo alcohol ethoxylates which contain 3 to 10, preferably 6 to 8 and in particular about 7 moles of ethylene oxide per mole of alcohol.
• foam regulators most of the time, the development of foam must be dampened.
• Suitable foam suppressants are, for example, the known silicone oils.
• the content of certain quaternary ammonium compounds and / or ethylene oxide adducts of primary fatty amines and / or of ⁇ -aminoalkyl / alkenyl-propionic acid salts of the formula R-NH-CH -CH is used in the agents according to the invention ⁇ COONa;
• Suitable quaternary ammonium compounds contain as long-chain alkyl or alkenyl radical with 10 to 20, preferably alkyl groups with 10 to 16 and in particular about 14 carbon atoms.
• the suitable quaternary ammonium compounds contain 3 of the same alkyl groups with 1 to 4 carbon atoms. In particular, these short alkyl groups are methyl groups.
• a particularly suitable and therefore preferred quaternary ammonium compound is tetradecyltrimethylammonium bromide. All or part of the quaternary ammonium compound can be replaced by the above-mentioned fatty amine ethoxylate.
• An example of a particularly suitable fatty amine ethoxylate is the adduct of 2 moles of ethylene oxide with primary coconut alkyl amine; this product is therefore also preferred.
• N-acyl and 0-acyl compounds are suitable as activators for per compounds.
• Acetyl compounds have proven particularly useful. Examples of this are tetraacetylglycoluril or pentaacetylglucose or in particular tetraacetylethylenediamine.
• the bleach activators mentioned lead to improved removal of bleachable textile soiling.
• the detergent additive according to the invention contains polyhydric alcohols which are able to prevent the known gelling of the nonionic surfactant on contact with water.
• Suitable antigelling agents are preferably polyhydric alcohols having 2 to 4 carbon atoms, which are intimately mixed with the non-ionic surfactant.
• the antigelling effect of the polyhydric alcohol can be enhanced if instead of the polyhydric alcohol alone a mixture of a polyhydric alcohol and condensation products of C10 to C20 fatty alcohols with 1 to 4 moles of ethylene oxide per mole of fatty alcohol is used.
• Polyhydric alcohols which can be used as antigelling agents are, for example, 1,2-propylene glycol, ethylene glycol or glycerol or mixtures of the alcohols mentioned.
• An example of a particularly suitable fatty alcohol ethoxylate which can be used in a mixture with the polyhydric alcohol to enhance the anti-gelling effect is tallow alcohol ethoxylate with 2 moles of ethylene oxide; but also C12 to C14 fatty alcohol ethoxylate with 3 moles of ethylene oxide, which contains approx. 70% C12 fatty alcohol ethoxylate, is suitable as an anti-gelling agent.
• the antigelling effect of the antigelling agent can be increased further if, in addition to the antigelling agents described hitherto, compounds which are readily soluble in water, in particular sodium borate, sodium chloride, sodium sulfate, sodium acetate or else sugar, are used.
• a viscosity of the bag contents in the range of 1,000 to 100,000 mPas is important for good dissolution behavior.
• a number of different additives can be used as viscosity regulators, for example water-insoluble zeolite, in particular of the zeolite A type, highly disperse silica, sheet silicates, in particular swellable sheet silicates of the bentonite and hectorite type, but also water-soluble salts, and the like
• Sugar, polyglycols or fatty alcohol ethoxylates with a high proportion of ethylene oxide A high proportion of ethylene oxide in fatty alcohol ethoxylates for the purposes of the present invention means that the fatty alcohol ethoxylate contains about 15 to 25 moles of ethylene oxide per mole of fatty alcohol.
• the washing additive advantageously contains small amounts of chelating agents.
• Water-soluble salts of alkane polyphosphonic acid from the group of the phosphonoalkane polycarboxylic acids and the amino and hydroxy-substituted alkane polyphosphonic acids, in particular the alkali salts of amino-tris (methylenephosphonic acid), dimethyleneaminomethane diphosphonic acids, 1-hydroxyethane-1,1-diphosphonic acid, 1-phosphonoethane-1,2-dicarboxylic acid, 2-phosphonobutane-1,2, 3-tricarboxylic acid and especially the hexasodium salt of ethylenediaminotetramethylenephosphonic acid.
• a polyvinyl alcohol film which meets these requirements is the subject of EP-OS 79 712. According to the teaching of this patent application, are solved Films made of polyvinyl alcohol in borate-containing washing liquors quickly and completely if the polyvinyl alcohol has a molecular weight below about 50,000 and / or if the polyvinyl alcohol contains a polyhydroxy compound with a certain binding constant with borate and / or if the polyvinyl alcohol contains an acid with a certain dissociation constant.
• the demand for rapid dissolution in washing liquors containing borate arises from the perborate usually used in detergents as a bleaching active ingredient.
• a film with satisfactory dissolving properties consists of polyvinyl alcohol with a molecular weight of approximately 10,000.
• the polyvinyl alcohol is 88% hydrolyzed and makes up 71% by weight of the film.
• the film also contains small amounts of glycerin, trimethylolpropane, sorbitol and water.
• the washing additive according to the invention is produced, for example, by heating the nonionic surfactant and mixing it with the foam inhibitor. When heated, the anti-gel agent and optionally the complexing agent are mixed in. The powdered viscosity regulators are then suspended with intensively acting mixing elements and the suspension is cooled. 14an receives a paste which is filled into a bag in an amount sufficient to increase the washing performance of commercially available detergents. The bags are closed by thermal welding or by moistening the edges with water and allowing them to dry while being compressed. A method of making the Washing additive is another object of the invention.
• This process is characterized in that the nonionic surfactant, if appropriate, is heated together with the foam inhibitor to 40 to 75 ° C., the antigelling agent and, if appropriate, the complexing agent are mixed with it, the activator for per compounds, the quaternary ammonium compound and / or the amine derivative and / or the Compound of the formula R-NH-CH 2 -CH 2 -COONa together with the viscosity regulators while introducing high shear forces suspended in the premix, then cooled to room temperature and covered with a bag-like structure made of a film based on polyvinyl alcohol which is readily soluble in borate-containing aqueous solutions.
• 35.9 g of this paste were in a bag (edge length 7.5 x 7.5 cm) made of a 65 ⁇ m thick film made of 71% by weight polyvinyl alcohol (molecular weight approx. 10,000, degree of hydrolysis 88%), 6% by weight glycerin, 6% by weight trimethylolpropane, 7.5% by weight sorbitol, balance water, filled; the bag was closed by thermal welding.
• Bags produced in this way were used to determine the dissolution behavior and the detergent-increasing effect.
• Example 1 Analogously to Example 1, an active substance paste was produced which additionally contained 0.720 kg of sorbitol, but no highly disperse silica and no sodium sulfate.
• the dissolving behavior and the washing-strengthening effect of the paste filled into bags as in Example 1 corresponded the product of Example 1.

• Example 6 is an example of a non-inventive paste. If a paste was only prepared from the nonionic surfactant, the quaternary ammonium compound, the activator for per compounds and the complexing agent and the foam regulator from Example 1, a paste was obtained which, upon contact with water, gelled to form a lump which did not separate within 15 minutes dissolved in the wash liquor.
