Definitions

• the wearing comfort of textiles can be improved by applying small amounts of mostly cationic compounds to the textiles, which gives the textiles a pleasantly soft feel and antistatic properties.
• the cationic compounds can be applied both before the first wearing and after a wearing period, for example in connection with washing. It is thus possible to apply the cationic compounds to the textiles in a tumble dryer during washing, rinsing or drying.
• the best use of fabric softeners is when you make sure that they are put on the washed laundry items during the rinsing process.
• the most effective plasticizers with regard to their plasticizing performance are quaternary ammonium compounds derived from ammonia or imidazoline with at least two long alkyl or alkenyl groups containing 10 to 20 carbon atoms. These compounds, which are used on a large scale because of their activity, are practically insoluble in water and are therefore added to the rinse water as dispersions, in which the less active ingredient the dispersions generally contain, the better they are distributed.
• the most common plasticizer dispersions therefore contain only about 5% by weight of plasticizer. This means that during production, packaging, transportation, Storage and use Considerable amounts of water are considered to be ballast.
• the invention was therefore based on the object of providing a ready-to-use, flowable fabric softener concentrate which has a high content of highly effective fabric softening active ingredients, is easy to handle and easy to dilute, has good effectiveness in the diluted state and does not have a low flash point which jeopardizes handling safety - points.
• This task was solved by a ready-made aqueous textile softener concentrate, which contains textile softening quaternary ammonium compounds and soap.
• the fabric softener concentrate is characterized in that it contains, in addition to the fabric softening quaternary ammonium compounds, an alkali metal soap or the corresponding fatty acids, glycerol and other water-soluble or water-miscible compatible organic solvents and water, the alkali metal soap or the corresponding fatty acid 1/70 to 1/3 of Make up the amount of textile softening quaternary ammonium compounds, and the content of the quaternary ammonium compounds in the concentrate is at least 30% by weight and the concentrate is in flowable, meterable form.
• the ready-made textile! plasticizer concentrates additionally non-ionic dispersants, which among other things improve the distributability of the active ingredients in water.
• the concentrates also generally contain a compatible acid, with which the pH is adjusted to at least 6.
• Compatible organic solvents and compatible acids within the meaning of the invention are those which harmonize with the other constituents of the concentrate and which, when used in the appropriate dilution, do not damage the items of laundry or the washing machine and, moreover, do not endanger the user of the concentrate.
• the concentrates according to the invention can be adjusted to a consistency and flowability which enables easy handling.
• the concentrates can easily be poured out of bottle openings with a diameter of about 3 to about 20 mm or they can be easily metered with metering devices for liquids, for example with the liquid container closure of DE-OS 30 26 067 serving as metering device.
• the actual solvent components of the concentrate according to the invention namely glycerol, organic solvents and water, are present in total in such amounts that they make up about 1/6 to about twice the quaternary ammonium compounds which soften the fabric; however, in the particularly preferred refinements or embodiments of the agent according to the invention, these amounts of solvent are clearly below 50% by weight. It is thus possible to design the concentrate according to the invention, for example, as a so-called "6 or 10-fold concentrate" with good flow properties.
• Particularly suitable quaternary ammonium compounds are those with two long-chain, saturated or unsaturated aliphatic groups each having 14 to 26, in particular essentially 16 to 20, carbon atoms and at least one quaternary nitrogen atom in the molecule.
• the long-chain aliphatic groups can be straight-chain or branched and can accordingly be derived from fatty acids or from fatty amines, Guerbetamines or from the alkylamines obtainable by reduction of nitroparaffins.
• These quaternary ammonium compounds are derivatives of ammonia, that is to say the quaternary salts obtainable by alkylation of long-chain secondary amines, such as. B.
• the compounds distearyldimethylammonium chloride or ditalgalkyldimethylammonium chloride or methosulphate, dioleyldimethylammonium chloride or methosulphate, ditalgalkylmethylhydroxyethylammonium chloride or methosulphate or ditalgalkylmethylhydroxypropylammonium chloride or methacrylate compounds through implementation tion of 1 mol of an aminoalkylethylenediamine or hydroxyalkylethylenediamine with 2 mol of a long-chain C 14 -C 26 fatty acid or its ester available imidazoline compounds which are then converted into the quaternary imidazolinium compounds by alkylation.
• the anion generally consists of the acid residue which has arisen from the alkylating agent used in the quaternization.
• the alkylating agent used in the quaternization For example, chloride, bromide, methyl sulfate, ethyl sulfate, methane, ethane or toluenesulfonate are suitable as anions.
• the quaternary ammonium compounds are also good antistatic agents.
• the quaternary ammonium compounds are mixtures of imidazoline derivatives and of ammonia derivatives each with two C 14 -C 26 -alkyl or alkenyl groups, especially if the imidazoline derivatives are two long-chain unsaturated groups, for example Contain oleyl groups. Concentrates according to the invention which contain such mixtures as component a) are therefore preferred.
• the fatty acids suitable as component b) are fatty acids with 8 to 20 carbon atoms. Both saturated and unsaturated fatty acids and also mixtures of saturated and unsaturated fatty acids can be contained in the concentrate according to the invention. Instead of or together with the fatty acids mentioned, the alkali metal salts, in general the sodium salts of the fatty acids mentioned, can also be used. Examples of suitable fatty acids or their alkali metal salts are mixtures which are derived from 20% by weight of coconut fatty acid and 80% by weight from tallow fatty acid or mixtures which are derived from 30% by weight of C 16 fatty acids and 70% Derive% by weight of C 18 fatty acids. These fatty acids and alkali soaps (b) are preferably in coordination with the quaternary ammonium compounds (a) such amounts that the weight ratio of a): b) is in the range from 20: 1 to 5: 1.

• An example of a suitable emulsifier is the adduct of 9.5 moles of ethylene oxide with nonylphenol. Liquid paraffin oil hydrocarbons are also suitable as emulsifiers.
• the concentrate according to the invention preferably has a pH of below 6. This is important insofar as the concentrate should expediently react with acid even after dilution with ten times the amount of water. Concentrates that have a pH of 3 to 6 undiluted meet this requirement; they are therefore preferred.
• acids compatible with textiles and the materials of washing machines such as, for example, the inorganic acids, hydrochloric acid, sulfuric acid, phosphoric acid, boric acid or else the organic acids, such as, for example, formic acid, acetic acid, benzoic acid, lactic acid, : Glycolic acid and especially citric acid.
