Description

"Laundry detergents with a fabric softener content" after drying washed textiles, especially those made of cotton or similar cellulose fibers, there is a clear hardening of the handle, especially when these textiles have been washed in drum washing machines. This appearance is particularly uncomfortable with laundry items that are used with human Come into contact with skin, especially underwear, bed linen and towels; but also with other items of laundry, such as table linen, for example great importance is attached to a comfortable grip.

It is true that this unexpected hardening of the handle during washing can be avoided avoid thereby adding cationic substances to the final rinse contain at least two higher molecular fat residues in the molecule. Have in practice for this purpose they can be suspended in water; Dialkyl dimethylammonium salts introduced.

It has already been proposed in English patent specification 1,052,847 that to add cationic fabric softeners to detergents based on anionic surfactants. The handle of the washed laundry can be improved in this way However, don't achieve it. The reason for this is that the cationic fabric softeners result in water-insoluble precipitates with the anionic surfactants.

The invention relates to detergents containing textile softeners, which do not have the disadvantages described.

These detergents are characterized by the following composition: a) 100 - 5J, preferably 95 - 8 and in particular 4 "- 10% by weight of a surfactant combination, containing: 10-95, preferably 30-70% by weight of anionic and / or nonionic and / or zwitterionic surfactants, 5 - 90, preferably 30 - 70% by weight of a textile softener, consisting of polyamino acid-N-alkylamides of the constitution given below as well as completely 0 - 8, preferably 0 - 4% by weight of non-surfactant foam inhibitors and b) 0-95, preferably 5-92 and in particular 55-90% by weight of other common detergent ingredients.

The other usual detergent ingredients include, for example, naturally to alkaline-reacting builders, complex binders, bleaching components, dirt carriers, brighteners, possibly also antimicrobial substances, etc. The fabric softeners present in the detergents according to the invention are polyamino acid N-alkylamides of the formulas in which R is hydrogen or alkyl radicals with 1-6 carbon atoms in which R is hydrogen or alkyl radicals with 1-4 carbon atoms, R "is alkyl radicals with 16-22 carbon atoms and x is a number between 3 and 10.

Polyamino acid N-alkylamides of the above formulas are preferably used an average degree of polymerization x - 5 is used.

The Textilwelohmacher used according to the invention can be selected from 100-0 % Polyamic acid-N-alkylamides of the form (I) and 0-100% polyamino acid-N-alkylamides of the form (II) exist.

Mixtures containing 90-60% polyamino acid N-alkylamides are preferred of form (I) in addition to 10 -b contain 40% polyamino acid-N-alkylamides of form (II).

If R and R 'represent alkyl radicals in the above formula, these can just like the alkyl radical R "can be straight-chain or branched-chain; Double bonds, heteroatoms, e.g. ether-oxygen and cyclic groups, e.g.

aromatic substituents.

Preference is given to polyamino acid N-alkylamides of the above formulas, in where R and R 'are hydrogen or methyl radicals and R "is a straight-chain alkyl radical with 16-22 carbon atoms.

The polyamino acid N-alkylamides which can be used according to the invention are can be prepared by polymerizing corresponding B-carboxy-amino acid anhydrides under Use of a primary alkylamine with at least 16 carbon atoms as a starter. as N-carboxy-amino acid anhydrides suitable for starting materials are derived from α-amino acids with 2 - 9 carbon atoms, e.g. of M-butylglycine, α-aminohexanecarboxylic acid, α- Propylminobutyric acid, phenylalanine and especially gygline, 1-alanine and sarcosine from which they can be obtained by implementing with @hosgen.

Primary alkylamines are particularly useful as initiators of the polymerization 16-22 C atoms can be used, which are also meteroatoms in the hydrocarbon residues, like ether-oxygen, and double bonds may contain. preferred straight-chain alkylamines are used as starters, as they are by amination natural fatty acids of the corresponding chain length can be obtained, e.g. cetyl, Stearyl, oleyl, arachinyl or behenylamine.

The amines can be used individually or as a mixture with one another will. Amine mixtures, for example, can also be used as initiators of the polymerization by amination of tallow fatty acids, fatty acids from hydrogenated palm oil and fatty acids have been obtained from hydrogenated rapeseed oil.

Polyamino acid-N-alkamides with one for their use in the invention Detergents suitable degree of polymerization are obtained if the corresponding Starter amine and N-carboxyamino acid anhydride in a molar ratio of 1: 3 to 1:10, preferably 1: 5 can be used. It is advisable to run the polymerisation at an elevated temperature, for example 50-100 ° C and a solvent, e.g. Dimethylformamtd, to add.

In addition to a main reaction, the polymerization takes place according to a chain termination reaction according to the following equation: The quantity distribution between the NH2-terminated form (I) and the COOH-terminated form (II) depends on the steric structure of the amino acid on which the N-carboxyamino acid anhydride is based and the basicity of the starter amine. In the case of the starting materials preferably used according to the above, the resulting polymerization products contain 90-60% polyamino acid-N-alkylamides of the form (I) in addition to 10-40% polyamino acid-N-alkylamides of the form (II).

After appropriate cleaning, the polymerization products are in Available in the form of white powders that melt with decomposition. They are insoluble in water, but easily dispersible in water.

The hydrophobic group is preferably an aliphatic hydrocarbon group with about 10-18 carbon atoms, but with deviations depending on the nature of the respective surfactant ton this preferred C-number range are possible.

As anionic washing active substances soaps are useful that of natural or synthetic fatty acids, including resin or naphthenic acids descend. There are many fatty, resin or naphthenic acids of natural origin more or less unsaturated. They are preferably in part or in full processed in the hydrogenated state so that they have iodine numbers of at most 30 and preferably less than 10.

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

The sulfonates include, for example, the alkylarylsulfonates, in particular the alkylbenzenesulfonates, which are obtained from, among other things, preferably straight-chain aliphatic Hydrocarbons with 9 to 15, preferably 10 to 14, carbon atoms by chlorination and alkylating benzene or from the corresponding terminal or i # permanent Olefins by alkylating benzene and sulfonating the resulting alkylbenzenes receives. Furthermore, aliphatic sulfonates are of interest, such as are preferred, for example saturated hydrocarbons containing 8-18 and preferably 12-18 carbon atoms in the molecule by sulfochlorination with sulfur dioxide and chlorine or sulfoxidation with sulfur dioxide and oxygen and conversion of the products obtained thereby into the sulfonates accessible are.

Mixtures of alkene sulfonates, Hydroxyalkene sulfonates and hydroxyalkane sulfonates useful, which can be obtained e.g. from end- or intermediate C8 - C18 and preferably C12 - C18 olefins by sulfonation with sulfur trioxide and acid or alkaline hydrolysis of the sulfonation products receives. The sulfonate group is found in the aliphatic sulfonates produced in this way often on a secondary carbon atom; but you can also implement it Bisulfite-terminated olefins Prepare sulfonates terminated with sulfonate groups.

To the invention. sulfonates to be used also include salts, preferably dialkali salts of α-sulfo fatty acids and salts of esters of these Acids with mono- or polyvalent, 1 - 4 and preferably 1 - 2 carbon atoms Alcohols.

Other useful sulfonates are the fatty acid esters of oxethanesulfonic acid and of dioxypropanesulfonic acid, the fatty alcohol esters of lower,; 1 to -8 carbon atoms containing aliphatic or aromatic sulfomono- and dicarboxylic acids, the Alkyl glyceryl ether sulfonates and the condensation products of fatty acids or Sulphonic acids with aminoethanesulphonic acid.

Fatty alcohol sulfates are to be mentioned as surfactants of the sulfate type, in particular those made from coconut fatty alcohols, tallow fatty alcohols or from oleyl alcohol. Useful sulfonation products can also be obtained from terminal or internal Cd C18 olefins Manufacture of the sulfate type. This group of surfactants also includes sulfated surfactants Fatty acid alkylamides, sulfated monoglycerides and sulfation products of ethoxylated ones and / or propoxylated fatty alcohols, alkylphenols with 8 to 15 carbon atoms in the alkyl radical, Fettsäureamiden, Fettsäurealkylolamiden, etc., with one mole of said ethoxylated and / or propoxylated compounds 0.5 to 20, preferably 1 to 8, in particular 2 to § mol of ethylene oxide and / or propylene oxide added on could be.

The detergents according to the invention can also be synthetic capillary-active Contain carboxylates, e.g. the fatty acid esters or fatty alcohol esters of oxycarboxylic acids as well as the condensation products of fatty acids or sulfonic acids with aminocarboxylic acids, e.g. with Glycocoll, Sarcosine or with protein hydrolysates.

To the nonionic surfactants, here for the sake of simplicity as "Nonionics" products, whose water solubility is due to the presence of polyether chains, Amine oxide, sulfoxide or phosphine oxide groups, alkylolamide groups and also whole generally owe to an accumulation of hydroxyl groups.

Of particular practical interest are those caused by the addition of Ethylene oxide and / or glycide on fatty alcohols, alkylphenols, fatty acids, fatty amines, Fatty acids and sulfonic acid amides, these zonionins 4 - 100, preferably 6 - 40 and especially 8 - 20 Xther residues, especially ethylene glycol ether residues may contain per molecule. In addition, these polyglycol ether residues or at the end of which propylene or butylene glycol ether residues may be present.

The nonionics also include those under the trade name "Plluronics", "Tetronics" or wUcon Fluid "known, water-soluble due to the addition of ethylene oxide made water-insoluble polypropylene glycols and addition products of propylene oxide of alkylenediamines or lower ones containing 1 to 8 and preferably 3 to 6 carbon atoms, aliphatic alcohols.

Other useful nonionics are 'fatty acid or sulfonic acid alkylolamides, which are e.g. from mono- or dialkylolamine, from dioxypropylamine or other polyoxyalkylamines, e.g. the glycamines. derive. They can be separated from higher primary amides or replace secondary alkylamines and polyhydroxycarboxylic acids.

From the group of amine oxides are those of higher tertiary, one hydrophobic alkyl radical and two shorter, up to 4 carbon atoms each containing alkyl and or amines derived from amines containing alkylol radicals are of particular interest.

Zwitterionic surfactants contain at least one acidic or at least a basic hydrophilic group in the molecule. The acidic groups include carboxyl, Sulphonic acid, sulfuric acid half-ester, phosphonic acid and phosphoric acid partial ester groups. The basic groups are primary, secondary, tertiary and quaternary ammonium groups in question.

Carboxy, sulphate and sulphonate betaines have been found to be well tolerated of particular practical interest with other surfactants. Suitable sulfobetaines obtained for example, by reacting tertiary, at least one hydrophobic alkyl radical containing amines with sultones, for example propane or butane sultone. Appropriate Carboxybetaine is obtained by reacting the tertiary amines mentioned with chloroacetic acid, their salts or with chloroacetic acid esters and cleavage of the ester bond.

The foaming power of the surfactants used can be determined by combining them increase or decrease suitable surfactants, as well as by adding non-surfactant organic substances can be changed.

As is known, those mentioned above are suitable as foam stabilizers Alkylolamide type nonionics; in addition, fatty alcohols or higher are used for this purpose Terminal diols useful.

The foaming power of synthetic anionic or nonionic surfactants can be reduced by adding soaps; with certain combinations of synthetic anionic surfactants, nonionics and soap, the foaming power is reduced even more. The addition products of propylene oxide to those described above are also notable capillary-active polyether glycol ether is characterized by a low foaming power, whereby by varying the number of ethylene glycol and propylene glycol residues present in the molecule Have products made with a wide variety of cloud points. These nonionics act at temperatures above their cloud point act on other nonionics at temperatures above their cloud point auf.andere nonionics as foam inhibitors; but they can also be combined with other surfactants or mixtures of different surfactants combine.

The foaming power of the surfactants can, however, also be known per se Reduce foam inhibitors that are not surfactants. Here (r may include chlorine en-containing N-alkylated aminotriazines, which are obtained by reacting 1 mol of cyanuric acid chloride with 2-3 mol of a mono- and / or dialkylamine with 6-20, preferably 8-18 carbon atoms in the alkyl radical. Also paraffins, haloparaffins, aliphatic C8 to C20 ketones can be used as foam inhibitors.

The aminotriazine derivatives described above have the advantage even foam-inhibiting against all types of tnside even when used in small quantities works; the other non-surfactant foam inhibitors are advantageous in combination used with soaps'.

The effect of the mentioned non-surfactant foam inhibitors and the preferably saturated soaps made from fatty acid mixtures with 2o-3o, preferably 20-26 carbon atoms is temperature dependent. If you combine them with good foaming, pre all things foaming well at low temperatures, surfactants or surfactant combinations, it can thus be achieved that the products in the medium temperature range up to, for example 650 C still foam well, but less and less with the transition to higher temperatures Develop foam. To increase the foaming power and foam resistance Foam stabilizers that act at the same time at low temperatures can be added to a product and incorporate foam inhibitors that act at a higher temperature.

In all of these triazine derivatives, the alkyl radicals were a mixture of Homologues with 8 - 18 carbon atoms. With similar success it was also use the monochlorotriazine derivative or the trialkylmelamine. Unless the products described contain synthetic sulfates or sulfonates together with soap, could use the other non-surfactant foam inhibitors mentioned in the description can be used, such as, for example, paraffin oil or paraffin. In the preparation of of the preparations became the related foam inhibitor in a suitable organic Solvent dissolved * which is in the molten state by means of a nozzle on the sprayed moving powdery preparation.

Examples T 1-T 21 describe surfactant combinations; the examples W 1 - W 21 describe detergents with. a content of such surfactant combinations. In all examples, the quantities given for the surfactants relate to the pure active ingredient; In the case of textile softeners, there can be certain amounts of by-products from the. Manufacturing is available. In practice, the surfactant combinations according to Examples T 1 - T 21 usually contain certain amounts of sodium sulfate, this for the most part from the manufacture of synthetic anionic surfactants from Sulfate or sulfonate derived. This information also applies accordingly to the Recaptures of Examples W 1 - W 21 existing surfactant combination.

The surfactant combinations T 1 - T 21 can also add additional Contains amounts of sodium sulphate or other salts as diluents. Commercial products can, for example, from 90-50% by weight of a surfactant combination according to the example T 1 - T 21 and 10 - 50% by weight of salts exist as co-solvents.

In the preparations according to Examples T 1 - T 21 were used as textile softeners the polyamino acid-N-alkylamides used, their preparation above under A to E and referred to below as fabric softeners A to E will.

In the tables below, the "+" sign in the "Na2SO4" line means that small amounts of sodium sulfate were present as an impurity that had been introduced by the anionic surfactants used. The "remainder consists to a large extent of water, also dyes and fragrances. If the Na2SO4 amount is indicated with +", the remainder also includes the sodium sulfate present. % By weight component in the surfactant combination Part of the nation according to example Tensiod combination T 1 T 2 T 3 T 4 T 5 T 6 T 7 ABS 42 32 - 37 44 33 30 Alkanesulfonate - - 42 - - - - Oleinsulfonate - 10 - - - - - TA sulfate - - - - - 11 - OA + 10 ÄO 14 14 14 17 14 14 - FS-amid + ÄO - - - - - - 13 Soap 1222 u - - - - - - 20 Soap 1622 - - - - 4 4 - Soap 1822 6 6 6 - - - - Fabric softener 38 38 38 43 38 38 32 Foam inhibitor - - - 3 - - 5 % By weight component in the surfactant combination Part of the nation according to example Surfactant combination T 8 T 9 T 10 T 11 T 12 T 13 ABS - 49 - - - 34 Olefin sulfonate - - - 32 32 - Fs-ester sulfonate - - 35 - - - KA sulfate - - 14 - - 8 TA sulfate - - - - - 3 OA + 10 ÄO - 16 16 16 16 18 KA + 20 ÄO 48 - - - - - KA + 9 ÄO + 12 PO - - - - - Soap 1218 - - - 15 - - Soap 1222 - - - - 14 - Fabric softeners 27 33 33 34 34 34 Foam inhibitor - 2 2 3 4 3 % By weight component in surfactant combinations according to the example Part of the Surfactant combination T 14 T 15 T 16 T 17 T 18 T 19 T 20 T 21 ABS 34 26 - - - - - 41 Alkanesulfonate - - - 40 - - - - Olfeinulfonat - - - - 20 - - - Fs-ester sulfonate - - 18 - - - - - OA - sulfate - - - - - - - - KA- sulfate 9 7 11 9 - 10 5 9 TA- sulfate - 2 - - 10 - 5 - OA-ÄO-sulfate - - - - - 20 - - KA-ÄO-sulfate - 8 - - - - - 17 TA-ÄO-sulfate - - - - - - 23 - OA + 5 ÄO - - 9 - - 24 14 - OA + 10 ÄO 11 - - 14 14 - - - Soap 1018 - - - - - - 15 - Soap 1218 9 - - - - - - - Soap 1222 - 22 28 - 27 23 - - Fabric softeners 34 35 34 35 29 23 34 31 Foam inhibitor 3 - - 2 - -3 2 Component of the% by weight component in the detergent according to the example Detergent W 1 W 2 W 3 W 4 W 5 W 6 W 7 Surfactant combination (+) 19.0 20.8 17.5 19.5 27.5 23.8 21.5 Na3PO4 - - - - - 1.8 2.3 Na4P2O7 - - - 12.0 - 6.5 20.2 Na5P3O10 45.0 32.8 19.5-32.0 38.0 23.8 NTA - - 18.0 19.0 - - - KDTA - - - - - - 1.3 EHLp - - 6.6 14.0 28.0 - - Na2O. 3.3 SiO2 4.5 2.9 4.0 4.5 7.5 5.5 5.5 Perborate 16.0 31.8 21.0 16.0 - 17.0 17.0 MgSiO3 1.0 2.5 1.6 1.0 1.6 2.0 2.0 CMC 1.5 0.8 1.3 1.5 1.3 1.2 1.2 rest (+) Any combination according to Examples T 1-T 12 can be used as a surfactant combination. % By weight of component b.
