Washed textiles, especially those made from cellulose fibers, are known to have an unpleasant hardening of the handle after drying. This occurs especially when the laundry is in the washing machine he follows. It is also known that this undesirable hardening of the handle can be eliminated by texti After washing in the last rinse bath, they are treated with cationic substances that contain at least 2 long-chain term aliphatic radicals in the molecule. In practice, especially those in water have been used for this purpose Suspendable dialkyl dimethyl ammonium salts introduced.

The disadvantage is that these softening substances have to be dosed separately from the main wash cycle in the household washing machine, since the textile softeners based on kaiionic surfactants are not are compatible with the anionic detergents in the detergent. When used together, the cationic products are removed from the washing system in the form of electron neutral salts and can therefore no longer be absorbed by the fibers. In order to avoid these difficulties, it is known from DE-OS 21 57 785. Manufacture detergents based on anionic surfactants, which contain a reaction product as a plasticizer of ethylene or propylene oxide and a C ₈ -C ₂₄ -alkyl-substituted alkanediamine.

If you work with detergents based on nonionic detergents, which are compatible with cationic softeners, a redeposition of the dirt occurs on the fiber, so that the washed pieces probably have a pleasantly soft feel, but the dirt particles are not loosened by the laundry. The object of the invention is to provide detergents containing softeners for laundry use give a soft handle, the plasticizer at the same time being compatible with the surfactants, in particular with anionic surfactants.

The invention relates to detergents with a content of about 4 to 70, preferably 6 to 60 wt .-% of a surfactant mixture consisting of an anionic, zwitterionic or nonionic surfactant or a mixture of these surfactants and customary additives in combination with a fabric softener.

The usual Waschmittelbejitandteile include z. B. neutral to alkaline reacting structural substances, Complex formers, bleach components, foam stabilizers, foam inhibitors, dirt carriers, enzymes and like that.

The condensation products from compounds of the formula 1 and II are primarily those in which the radicals R and R are alkyl groups. Because they are produced from natural fatty acid mixtures, mixtures of condensation products which contain a minor proportion of compounds in which R and / or R _{1 are} alkenyl radicals can also be used as plasticizers. 3n

The preparation of the condensation products according to the invention is done in a simple manner by reacting the Alkylpropyleridiamin-oxyalkylate of the formula II with the fatty acid or esters thereof in the specified molar ratio oei temperatures of about 130 ° to 25O ° C, preferably 160 ° to 200 ⁰ C. Depending on the temperature used and the fatty acid components used, up to 10 hours, usually about 2 to 8 hours, are necessary to achieve the reaction equilibrium. In condensation under reduced pressure, the reaction can be carried out already at a lower temperature, for example 120 ° to 160 ⁰ C.

After the end of the condensation, the melt of the reaction product can be cooled and the product in in a known manner, e.g. by means of a chill roll in flake form or by means of an extruder in Grantcüform or be brought into powder form by atomization. Before this shaping, the melt of the reaction product can, if necessary, by adding water-soluble organic acids or mineral acids weakly alkaline to weakly acidic (pH 4 to 8).

It is, however, also possible, in a modification of this procedure, to disperse the melt of the reaction product in water, with either the melt rising after it has been adjusted to be weakly alkaline to weakly acidic about pH 4 to 8 stirred into water with a water-soluble strong organic or inorganic acid is, or wherein the melt is stirred into water and at the same time or afterwards the organic or inorganic acid is added. The organic or inorganic acids used are primarily mineral acids, such as hydrochloric acid, phosphoric acid, sulfuric acid, and acetic acid or oxalic acid. You get such an aqueous dispersion of the plasticizer that can be diluted with cold water, which is suitable for incorporation into the Detergent added directly to the detergent paste to be atomized or sprayed onto the detergent can be.

The incorporation of the condensation products from compounds of the formulas I and II for the preparation of the Laundry detergents according to the invention with a fabric softening effect can also be used in various ways known methods.

For optimal utilization of the textile-softening effect, it is recommended that the condensation products be present in the detergents according to the invention in a very fine distribution.

This desired very fine distribution can be achieved by either the finely pulverized Condensation products are evenly mixed with the other detergent particles, or the condensation products are dissolved in molten form or in suitable liquid carriers, in particular water or sprayed dispersed onto the remaining solid washing powder particles so that they are completely or partially enveloped or that the condensation products are incorporated into the detergent pastes to be atomized. Aqueous dispersions of the condensation products are particularly suitable for this purpose.

! 30 acid ester or carbonamide groups in question.

The hydrophobic radical is preferably an aliphatic hydrocarbon radical with about 10 to 18, preferably 12 to 18, carbon atoms, although deviations therefrom depending on the nature of the respective surfactant preferred number range are possible.

Soaps made from natural or synthetic fatty acids, optionally also as resin or naphthenic acids, can be used as anionic washing active substances, especially if these acids have iodine numbers of at most 30 and preferably less than 10.

Of the synthetic anionic surfactants, the sulfonates and sulfates are of particular practical importance.

The sulfonates include, for example, the alkylarylsulfonates, in particular the alkylbenzenesulfonates. the among other things, preferably straight-chain aliphatic hydrocarbons with 9 to 15, in particular 10 to 14 C atoms by chlorination and alkylation of benzene or from corresponding terminal or internal Olefins obtained by alkylating benzene and sulfonating the resulting alkylbenzenes. Furthermore, aliphatic sulfonates are of interest, as they are, for. B. from preferably saturated, about 8 to 18 and preferably 12 Hydrocarbons containing up to 18 carbon atoms in a straight chain in the molecule by sulfochlorination with Sulfur dioxide and chlorine or sulfoxidation with sulfur dioxide and oxygen and transferring the thereby raised products in the sulicnate are accessible. Alkene sulfonates are also used as aliphatic sulfonates. Hydroxyalkanesulfonates and disulfonates containing mixtures useful, which one z. B. from terminal or central olefins with about 8 to 18 carbon atoms by sulfonation with Schefeltrioxid and acidic or alkaline Hydrolysis of the sulfonation products is obtained. The aliphatic sulphonates produced in this way include the Sulfonate group multiple on a secondary carbon atom; but you can also use sulfonates with a terminal sulfonate group obtained by reacting terminal olefins with bisulfite.

The sulfonates to be used according to the invention also include salts, preferably dialkali salts of tf-sulfofatty acids and salts of esters of these acids with mono- or polyhydric alcohols containing 1 to 4 and preferably 1 to 2 carbon atoms.

Further useful sulfonates are salts of fatty acid esters of oxethanesulfonic acid or dioxyprupanesulfonic acid. the salts of the fatty alcohol esters of lower aliphatic or aromatic sulfomono- or dicarboxylic acids containing 1 to 8 carbon atoms, the alkyl glyceryl ether sulfonates and the salts of the amide-like Condensation products of fatty acids or sulfonic acids with aminoethanesulfonic acid.

Fatty alcohol sulfates are to be mentioned as surfactants of the sulfate type, in particular those made from coconut fatty alcohols. N) tallow fatty alcohols or made from oleyl alcohol. Also from terminal or internal olefins with about 8

up to 16 carbon atoms, useful sulfonation products of the sulfate type are available. Furthermore, * u belong to this

Group of surfactants sulfated fatty acid alkylolamides or fatty acid monoglycerides and suifted alkoxy

products of alky! phenols (C ₈ - ₁₅ alkyl), fatty alcohols, fatty acid amides or fatty acid alkylolamides

Suitable anionic surfactants of the carboxylate type are, for. B. the fatty acid esters or fatty alcohol ethers of Hydroxycarboxylic acids and the amide-like condensation products of fatty acids or sulfonic acids with Aminocarboxylic acids such as glycocolla, sarcosine and the like.

The non-ionic surfactants include products whose water solubility is due to the presence of polyether chains, Amine oxide, sulfoxide or phosphine oxide groups, alkylolamide groups and in general owe to an accumulation of hydroxyl groups.

Of particular practical interest are those caused by the addition of ethylene oxide and / or propylene glycol products available on fatty alcohols, alkylphenols, fatty acids, fatty amines, fatty acid or sulfonic acid amides. which contain about 4 to 60, in particular 8 to 20 ether residues, especially ethylene glycol ether residues per molecule can.

The nonionic surfactants also include those produced by the ethoxylation of water-insoluble ones Polypropylene glycols or of water-insoluble propoxylated lower, 1 to 8, preferably 3 to 6 carbon atoms containing aliphatic alcohols or or from water-insoluble propoxylated alkylenedia- ι ο mines are preserved.

The nonionic surfactants also include fatty acid or sulfonic acid alkylolamides. which z. B. from Mono- or diethanolamine, from dihydroxypropylamine or other polyhydroxyalkylamines, e.g. B. the glycamines derive. They can be replaced by amides from higher primary or secondary alkylamines and polyhydroxycarboxylic acids substitute.

Capillary-active amine oxides are also suitable surfactants; these include B. those of higher tertiary, one hydrophobic alkyl radical and two shorter, up to 4 carbon atoms each containing alkyl and / or Products derived from amines.

Zwitterionic surfactants contain both acidic and basic hydrophilic groups in the molecule. To the acidic groups include carboxyl, sulfonic acid, sulfuric acid half-ester. Phosphonic acid and phosphoric acid partial ester groups. The basic groups are primary, secondary, tertiary amine and quaternary ammonium groups in question. Zwitterionic compounds with quaternary ammonium groups belong to the betaines type.

The foaming power of the surfactants can be increased or decreased by combining suitable types of surfactants, just as it can be changed by adding non-surfactant organic substances. as Foam stabilizers are particularly suitable for surfactants of the sulfonate or sulfate type, capillary-active carboxy- or sulfobetaines and the above-mentioned nonionics of the AlkyloUjmidtyp; also are for this purpose Fatty alcohols or higher terminal diols have been suggested.

Products with reduced foaming power are primarily intended for use in washing machines and dishwashers, with limited foam dampening sometimes being sufficient, while in other cases more foam dampening may be desirable. Of particular practical importance are products which still foam in the medium temperature range up to about 65 ^° C., but develop less and less foam when transitioning to higher temperatures up to / u 100 ^{° C.}

A reduced foaming capacity is often obtained with combinations of different types of surfactants. in particular in the case of combinations of synthetic anionic surfactants, especially of sulfates and / or sulfonates or from nonionic surfactants on the one hand and from soaps on the other.

The foaming power of the surfactants can, however, also be increased by adding substances which are known per se, but which are not surfactants Reduce foam inhibitors.

Weakly acidic, neutral and alkaline substances are suitable as builder substances for the detergents according to the invention reacting inorganic or organic salts, in particular inorganic or organic complex -to sculptor.

Usable, slightly acidic, neutral or alkaline salts are, for example, the bicarbonates, carbonates or silicates of alkalis, furthermore mono-, di- or ^ alkali orthophosphates, di- or tetraalkali pyrophosphates. as complexing agents known metaphosphates, alkali sulfates and the alkali salts of organic, non-capillary-active sulfonic acids, carboxylic acids and sulfocarboxylic acids containing 1 to 8 carbon atoms. These include, for example, water-soluble salts of benzene, toluene or xylene sulfonic acid, and water-soluble salts Salts of sulfoacetic acid, sulfobenzoic acid or salts of sulfodicarboxylic acids and the salts of acetic acid, Lactic acid, citric acid and tartaric acid.

The weakly acidic metaphosphates are also suitable as complex-forming structural substances and the alkaline polyphosphates, especially tripolyphosphate. They can be in whole or in part be replaced by organic complexing agents. The organic complexing agents include, for example Nitrilotriacetic acid, ethylenediaminetetraacetic acid, N-hydroxyethyl-ethylenediamine triacetic acid, Polyalkylene-polyamine-N-polycarboxylic acids and other known organic complexing agents, whereby also Combinations of different complexing agents can be used.
