Description

AT 396479 B

The invention relates to a particulate, based on the weight, 5 to 40% water-soluble non-soap-like anionic surfactant and 10 to 60% water-soluble neutral to alkaline builder salt existing detergent and softening agent, which is able to in the so treated textiles to ensure improved softening, cleaning effect, antistatic properties as well as preventing the re-precipitation of dirt, especially when washing in a machine.

Detergents that can be used to clean or wash textiles in the machine at the same time and soften them to a considerable extent, and which are therefore suitable for use in a washing program, are well known and widely available commercially. Also well known in the patent literature is the occasional interaction between anionic surfactant (the most commonly used type of surfactant) and cationic plasticizers, especially those of the quaternary di (lower) alkyl di (higher) alkyl ammonium salt type. This interaction often leads to the formation of invisible precipitates, which are held inside or on the washed textile part. Discoloration or other aesthetically unpleasant effects are usually not avoidable. The net result is often a reduction in the effective amount of anionic surfactant available since the loss of anionic surfactant is the main consequence of this interaction. IS Although the most effective types of cationic quaternary ammonium plasticizers (such as the above-mentioned quaternary compounds disubstituted with higher alkyl, e.g. distearyldimethylammonium chloride) may be effective in the presence of anionic surfactant, builder, etc. in the wash cycle the amount needed for effective softening is mostly in the same range as the amounts that favor undesirable cationic / anionic interaction. As a general rule, at least about twice as much cationic surfactant is required for softening as for antistatic effects.

The cationic / anionic problem and associated adverse effects are discussed in detail in U.S. Patent No. 3,325,414, which is primarily concerned with detergents whose foamability is controlled. This patent also indicates that certain quaternary ammonium compounds, which fall into the class of cationic agendas are generally unstable when heated and in contact with alkaline builders, the instability being evidenced by the development of strong amine odors and undesirable coloring. The detergents according to this patent are limited to the use of quaternary ammonium halides with only one higher alkyl group, and the structural formula given is accordingly restricted for the cationic compounds. Cationic compounds of this type are inferior to the di- (higher) -alkyl compounds meik-30, at least as far as the text softening process is concerned

The problem of incompatibility of cationic substances in anionic detergents is also addressed in US Pat. Nos. 3,936,537 and 4,141,841, and it is suggested here that an organic dispersion inhibitor be used as an essential component in combination with the cationic compound. An important characteristic of these inhibitors is a maximum solubility in water at 25 ° C of 50 ppm. Similar 35 specifications can be found in U.S. Patents 4,113,630, 4,196,104 and 4,272,386. US Pat. No. 4,230,590 discloses heavy duty laundry detergents which contain conventional builders, mainly anionic surfactants, cationic plasticizers and a mixture of fatty acid soap and cellulose ether. The soap-cellulose ether mixture is in spaghetti, flake or other form and is present in the detergent essentially in homogeneously dispersed discrete particles. 40 Heavy duty detergents are disclosed in U.S. Patent 4,298,480 which, except that they do not contain cellulose ethers, have a composition similar to that of the detergents described in the previous paragraph.

Heavy duty laundry detergents are also disclosed in U.S. Patent 4,329,237, which are also similar to those of the two previous paragraphs, except that the soap particles are mixed with nonionic surfactant.

According to GB 2133 813A, further improvements of these detergents were achieved, for example less greasy 45 stains or stain-like discolorations by the cationic plasticizer, by adding discrete particles (e.g. prill products) of a mixture of the in addition to the anionic surfactant and the builder and homogeneously mixed with them cationic amine plasticizer with non-ionic surfactant.

The prior art also includes US Pat. Nos. 4,339,335,4326,971.4,416,811.4,411,803.4,450,085 and 4,414,129, all of which disclose granular or powder detergents and softeners. 50 Although the above mentioned surfactant / soap and cationic softener detergents have desirable softening, antistatic and cleaning properties, there is a desire to further improve these properties while reducing the overall cost of the product.

The object of the invention is to provide stable washing and softening agents which ensure improved softness without staining, cleaning power, antistatic properties and prevent the re-precipitation of dirt-55 de properties in textiles washed with them in cold or warm water.

To achieve the object of the invention, washing and softening agents are proposed according to the main claim, the subclaims define preferred embodiments of the invention. -2-

AT396479B

The washing and softening agent of the type mentioned at the outset is characterized according to the invention in that it is an intimate mixture of (i) 2 to 20% by weight, based on the total composition, which is essentially homogeneously dispersed in the mixture of surfactant and builder salt in discrete particles , cationic amine plasticizer with (ii) a water-soluble, ethoxylated, tertiary amine as a dispersing / plasticizing agent, the percentage concentration of anionic surfactant being at least (1.5 KS) +5 and KS being the percentage concentration of the total plasticizer The cationic amine (i) is preferably a quaternary di- (short-chain) alkyl, di- (long-chain) alkylammonium halide, preferably a di- (Cj-bis-C4) alkyl - di- (Cj4-bis-C ig) - alkylammonium halide or an imidazolinium compound or a mixture thereof. The amount of ethoxylated, tertiary amine preferably makes up 2 to 50% by weight, in particular 2 to 20% by weight, of the mixture of (i) and (ii).

As described in the above-mentioned GB 2133 813 A, the addition of the cationic material intimately mixed with nonionic organic surfactant in flake, granule or the like form has the advantage that the stains or discoloration of the textiles after drying are significant be mitigated. Because the non-ionic surfactant acts as a dispersant to improve the uniform dispersion of the cationic softener and hence its uniform deposition on the treated textiles, the non-ionic surfactant also contributes to the uniform softening and inhibition of dirt reprecipitation, especially in non-phosphate containing formulations , at.

However, the nonionic, ethoxylated fatty alcohol serving as the dispersant does not per se improve the level of softening provided by the cationic fabric softener. While it is not entirely clear why the non-ionic dispersant does not increase softening, it is believed that the reason is that it is not substantive to the washed fabrics, i.e. H. the non-ionic dispersant is not bound to them.

Numerous types and classes of textile softening compounds are known, primarily nitrogen-containing compounds, such as the quaternary ammonium salts and imidazoline salt compounds. Nonetheless, a softening active compound must meet a number of different criteria if it is the " non-active " Dispersant in the subsequently added softening particles, e.g. B. prill products of GB 2 133 813 A, should replace. The softening compound must also act as a dispersant for the particulate, cationic, fabric softening compound when the prilipi products are added to the wash water, and must promote solubilization or disintegration of the prill bodies after addition to the wash bath. Of course, if this connection is to be suitable, this connection must also be compatible, i. H. not be reactive with the cationic fabric softener. It must also be processable in the form of prills, granules or other discrete particles and must be compatible with the surfactant, builder and other components of the detergent composition. This compound, which is intended to replace the non-ionic surfactant acting as a dispersant, should also contribute to the antistatic behavior of the entire detergent or at least not adversely affect it.

It has now been found that by replacing the nonionic surfactant, the ethoxylated alcohol, as the dispersant with an equivalent amount of an ethoxylated tertiary amine, the total amount of the cationic plasticizer (in the form of its mixture with the ethoxylated amine) is significantly reduced can be achieved without a corresponding reduction in the softening imparted to the treated textiles and in some cases with improved softening. There is also no deterioration in the antistatic properties of the treated textiles. So while the overall cleansing, softening, antistatic and anti-reprecipitation properties are improved or not impaired, the ability to reduce the amount of plasticizing cationic amine, which is usually the most costly ingredient in the formulation, has a significant potential Cost savings result.

Cationic plasticizers which can be used according to the invention are known per se and belong to the highly plasticizing lipid. They include the quaternary NJi-di - ((higher> Cj4 to C24), N, N-di ((lower) -C j to C4) alkylammonium salts with water-solubilizing anions, e.g. halides such as chloride, bromide, and iodide, sulfate, methosulfate and the like, and the heterocyclic imides, for example the Mdazolinium compounds.

The aliphatic quaternary ammonium salts can expediently have the following structure

AT396479B are defined, wherein R and R * each represent an alkyl radical having 14 to 24, preferably 14 to 22 carbon atoms; and each represent a lower alkyl radical having 1 to 4, preferably 1 to 3 carbon atoms, X is an anion which imparts water solubility or dispersibility, including the anions mentioned, chloride, bromide, iodide, sulfate and methosulfate.

Particularly preferred aliphatic quaternary compounds include: distearyldimethylammonium chloride, di (hydrogenated) tallow dimethylammonium chloride, ditallow dimethylammonium chloride, distearyl dimethylammonium methyl sulfate and di (hydrogenated) tallow dimethylammonium methylsul £ aL

Heterocyclic imide plasticizers of the imidazolinium type can also be used and have the following structure

x- are defined, wherein R ^ represents a lower alkyl group having 1 to 4, preferably 1 to 3, carbon atoms; R ^ and each are essentially linear, higher alkyl groups with 13 to 23, preferably 13 to 19 carbon atoms and X have the meaning mentioned above. Particularly preferred imidazolinium compounds include: l-methyl-l-tallowamidoethyl-2-tallow-imidazolinium methyl sulfate, available from Sherex Chemical Co. under the trade name V ARISOFT 475 is available as a liquid with 75% active ingredients in isopropanol as a solvent; and l-methyl-l-oleylamidoethyl-2-oleyHmidazolinium methyl sulfate, also available from Sherex Chemical Co under the tradename VARISOFT 3690 with 75% active ingredient in isopropanol as a solvent

Mixtures of these cationic fabric softeners can be used, including mixtures of quaternary ammonium salt and imidazolinium salt.

The ethoxylated amine compounds useful in the present invention are the ethoxylated tertiary amines represented by the following formula

(CH2CH20) xH

R-1T

^ (C ^ CH ^ yH can be reproduced, in which R is an organic substituent of the fat series, and x and y stand for positive numbers whose sum x + y is 2 to 15.

Preferred examples of the organic substituent R of the fat series are linear or branched alkyl or alkenyl groups (the linear ones are preferred), which can contain 8 to 22 carbon atoms, especially 12 to 20 carbon atoms. The Sumex + y is preferably 5 to 15. Specific examples of suitable R groups include the decyl, dodecyl, stearyl, tallow, (hydrogenated) tallow, myristoyl, oleyl and the like residues, which generally differ from the corresponding higher fatty acid deduce. Mixtures of different alkyl chain lengths are usually used, such as. B. C ^ - to -C15 C14- to -Cjg, Cjg- to -Cjg, Cjg- to -C20 and so on. Stearyl, tallow and hydrogenated tallow compounds are readily available commercially, such as the Aimak Chemical Co.'s Ethome series, e.g. B. Ethomeen T / 25 (R = tallow, x + y = 15); Ethomeen T / 15 (R = tallow, x + y = 5); Ethomeen 18/15 (R = octadecyl (stearyl), x + y = 5); and the Varonic series from Sherex Chemicals, e.g. B. Varonic T-215 (R = tallow, x + y = 15); Varonic T-210 (R = tallow, x + y = 10); Varonic U215 (R = mixture of cetyl / stearyl, x + y = 15); Varonic U205 (R = mixture cetyl / S tearyl, x + y = 5); and are preferred according to the invention because of their high efficiency and relatively low price

According to the invention, the ethoxylated fatty amines have a double function: as a dispersant for the -4-

AT396479B cationic fabric softener, showing an effect equivalent to that of the non-ionic surfactant (the ethoxylated fatty alcohol) in the detergents of the aforementioned British patent application, and also as a softening active nitrogen compound per se. Because of the advantage of this additional softening, the total amount of cationic textile softener 5 subsequently added to the powdery detergent can be used for the same total content of active softening compounds (cationic softener plus ethoxylated

Amine) willows reduced, whereby approximately the same softening and antistatic effect are achieved. However, the amount of the subsequently added softening / antistatic granules, prill bodies etc. can also be kept in the same order of magnitude, an additional increase in the softening and antistatic effect then being obtained. 10 The cationic-non-ionic mixture is preferably produced in prilled form. The " Prills " or

Prill products or prill bodies are made by spray cooling a liquefied mixture of the cationic and the ethoxylated amine. In the most preferred embodiment, a liquid ethoxylated amine is used and added to the melted cationic compound. A typical cationic substance is Arosurf TA-100 (dimethyldistearylammonium chloride), a material which, when melted and heated to 90 ° C., forms a very fluid liquid. According to another preferred embodiment, the liquid mixture of cationic substance and ethoxylated amine can be left to cool to room temperature or to the extent necessary for solidification. The solid substance can then be ground to the desired particle size and subsequently added to the other detergent components.

Alternatively, the cationic and ethoxylated amines, when combined, may first be mixed in the desired amounts to form a substantially homogeneous mass which can be processed according to known processing techniques until sufficiently " doughy " or is plastic in order to be extruded (preferably) or another method, e.g. B. pelletizing, granulating, punching or pressing. Processing can take place, for example, by rolling, although this is not essential, and subsequent extrusion using a conventional peloton jar or soap extrusion press with the desired extrusion head. The latter is chosen with a view to the desired geometric shape of the extrudate. It is preferably extruded in the form of spaghetti or pasta. Other forms, such as flakes, tablets, pills, tapes, threads and the like, are suitable alternatives. Special extruders for the above-mentioned purposes are known to the person skilled in the art. They include, for example, the Elanco models EXD-60; EXCD-100; EX-130 and EXD-180, a Buhler extruder and the like. The spaghetti extrudate is usually a shape-retaining mass, i. H. semi-solid and essentially non-sticky at room temperature, and in most cases requires no treatment other than water removal. If necessary, this can be done using simple drying techniques. The spaghetti are said to have an average length of 2 to 20 mm (about 95% of them within a tolerance of 0.5 to 20 mm) and an average diameter or width of 0.2 to 2.00 mm, with a range of 0.4 to 0.8 mm is preferred. The bulk density of the spaghetti is usually 0.9 to 1.3 g / fcn A. The flake dimensions are 4 mm in length and width and 0.2 mm in thickness. Pills have a cross section of 2.5 mm, while tablets have a cross section of 2.5 mm and a thickness of 2.5 mm.

Generally about 1 to 20 weight percent ethoxylated amine based on the weight of the cationic softener is provided. The ethoxyliote amine should preferably be used in amounts of 5 to 15%, 40 to 8% being particularly preferred.

Conventional surfactants can be used in accordance with the invention, but it is preferred that at least 90, preferably at least 95% of the total surfactants are anionic, since these are particularly advantageous in heavy-duty detergents for washing textiles. Anionic surfactants useful in the present invention include the water-soluble salts of organic reaction products which have an anionic solubilizing group such as SCtyH, SO3H, 45 COOH and PO4H, and an alkyl or alkyl group having 8 to 22 carbon atoms in the alkyl group. Suitable toisides are anionic surfactant salts with alkyl substituents having 8 to 22 carbon atoms, such as, for example: water-soluble sulfated and sulfonated anionic alkali and alkaline earth metal surfactant salts and surfactant salts which have a higher alkyl radical as a hydrophobic part, as well as the salts of mono- or poly-sulfonated aryl substituted with higher alkyl 18 carbon atoms in the 50 alkyl group, which can be straight-chain (preferred) or branched-chain. Preferred substances include, but are not limited to: sodium (linear) tridecylbenzenesulfonate, sodium (linear) dodecylbenzenesulfonate, sodium (linear) decylbenzenesulfonate, lithium or potassium pentapropylenebenzenesulfonate; Alkali salts of sulfated condensation products of ethylene oxide, which contain, for example, 3 to 20 and preferably 3 to 10 moles of ethylene oxide, with aliphatic Cg to Cjg alcohols or with alkylphenols which have 6 to 55 18 carbon atoms in the alkyl group, e.g. B. sodium nonylphenol pentaethoxamer sulfate and sodium lauryl alcohol triethoxamer sulfate; Alkali salts of saturated alcohols containing 8 to 18 carbon atoms, e.g. B. sodium lauryl sulfate and sodium stearyl sulfate; Alkali salts of esters of higher fatty acids with (low) alkylolsulfonic acids, -5-

AT396479B e.g. B. fatty acid esters of the sodium salt of isethionic acid; Fatty ethanol amide sulfates; Fatty acid amides of amino-alkyl sulfonic acids, e.g. B. Taurine lauric acid amide; Alkali salts of hydroxyalkanesulfonic acids with 8 to 18 carbon atoms in the alkyl group, e.g. B. HexydecylalphahydroxynatriumsulfonaL The anionic surfactant or mixture thereof is advantageously used in the form of its alkali or etdalkali salts. The anionic 5 surfactant is preferably of the non-soap type, but you can add small amounts of soap, for example up to 35 and preferably 20%, to the Crutcher mixture. , based on the total anionic surfactant.

The concentration of the non-soap anionic surfactant is chosen so that an excess over the cationic plasticizer is ensured, in accordance with the following relationship: 10% concentration = 1.5 KS + 5,

where KS represents the percentage concentration of the cationic plasticizer

This ensures the minimum excess of anionic surfactant because * for optimal overall cleaning, softening, etc., d. H. Effect of the overall product is required. 15 Together with the anionic surfactant, smaller amounts of other types of surfactants can be incorporated

In any case, the total does not exceed 10%, preferably 2 to 5% of the total surfactant (ie such other surfactants plus non-soap anionic surfactant). The nonionic surfactants with an organic hydrophobic and a »hydrophilic group, which are a reaction product of a solubilizing, can be used for this purpose Group such as carboxylate, hydroxyl, amido or amino with ethylene oxide or the polyhydration product 20 thereof, polyethylene glycol. These include the condensation products from Cg to C 13 fatty alcohols, such as

Tridecyl alcohol with 3 to 100 moles of ethylene oxide; Cjg to Cjg alcohols with 11 to 50 moles of ethylene oxide; Ethylene oxide adducts with monoesters of polyvalent, e.g. B. 6-valent alcohol; Condensation products of polyprypyte glycol with 3 bis 10 Moles of ethylene oxide; the condensation products of A] alkyl (C6 to C20, straight or branched) phenols with 3 to 100 moles of ethylene oxide and the like. Suitable amphoteric surfactants generally include those that have both an anionic group and a cationic group and a hydrophobic organic group, which is preferably a higher aliphatic group with 10 to 20 carbon atoms. Examples of these are the N- (long chain > -Alkylaminocarboxylic acids and the N-flangkettig < ») - alkylimmodicarboxylic acids as described in US-PS3824189. The detergents according to the invention contain water-soluble alkaline to neutral builder salts in amounts of 10 to 60% by weight of the total composition. Usable are the organic and inorganic builders including the alkali and alkaline earth phosphates, especially the condensed phosphates such as the pyrophosphates or tripolyphosphates, silicates, borates, carbonates, bicarbonates and the like. Special compounds include sodium tripolyphosphate, trisodium phosphate, tetrasodium pyrophosphate, acidic sodium pyiophosphate, 35 monobasic sodium phosphate, dibasic sodium phosphate, sodium hexametaphosphate; Alkali silicates such as sodium metasilicate, sodium silicates, for example with Na20 / SiO2 ratios of 1.6: 1.2 to 3.2: 1, preferably 1: 6 to 1: 3.4, especially 1: 2 to 1: 3, especially 1: 2.4, sodium carbonate , Sodium sulfate, borax (sodium tetraborate), the tetrasodium salt of ethylenediaminetetraacetic acid, trisodium nitriloacetate and the like, and mixtures thereof. The builder salt is chosen depending on whether one will produce phosphate-containing or phosphate-free detergents 40. Sodium carbonate is particularly effective for the latter. Another material that provides good washing effects is metaikaolin, which is usually obtained by heating raolinite (lattice form), which drives off the water and gives a material which is shown to be essentially amorphous by X-ray examination, but with a certain structural order of Maintains kaolinits. In U.S. Pat. No. 4,075,280, columns 3 and 4, and in "The Chemistry and Physics of Clays and Allied Ceramic Materials", Grimshaw, 45 (4th edition, Wiley-Interscience) pages 723-727, there are explanations about kaolin and metakaolin. The

Metakaolin also appears to be useful as a plasticizer. The most potent metakaolines appear to be those that react best with sodium hydroxide to form zeolite 4A, as described in U.S. Patent No. 3,114,603, which describes these materials as " reactive kaolin " be designated. After the explanation »! in the sources indicated, metakaolin is an aluminosilicaL The metakaolin and / or a zeolite is incorporated in the same 50 quantities as the builder salt, preferably in addition to it, for example zeolite: silicate in one

6: 1 ratio. A particularly advantageous form of metakaolin is available as Satintone No. 2.

Preferred optional ingredients according to the invention include fragrances; optical brighteners and bluing agents, which can be dyes or pigments. Suitable materials for this are, for example, stilbene and Tinopal 5BM brighteners, in particular in combination, as well as Direct Brilliant Sky Blue 6B, Solophenyl Violet 4BL, 55 Cibacete, Brilliant Blue RBL and Cibacete Violet B, Polar Brilliant Blue RAW and Calcocid Blue 2G as bluing agents. The brightener can be incorporated in amounts of up to 1%, based on the total composition, while bluing agents in the range of up to 0.1, preferably up to 0.01%, of the detergent -6-

AT396479B may be included. Bluing agents such as B. polar brilliant blue, may be present in the cationic prill product.

Other optimal ingredients include bleaching agents which can be of the oxygen or chlorine releasing type. Oxygen bleaches are, for example, sodium and potassium perborate, potassium monopersulfate and the like. Chlorine bleaches are, for example, sodium hypochlorite, potassium dichloroisocyanurate, trichloroisocyanurate acid and the like. The latter chlorine-releasing bleaches are representative of the large class of water-soluble, organic, dry bleaches known as N-chloroimides, including their alkali salts. These cyclic imides with 4 to 6 " links " in the ring are described in U.S. Patent 3,323,414. All the bleaches of the oxygen and chlorine type mentioned are completely compatible with the detergents 10 according to the invention and, in the presence of the anionic and cationic components, have good resistance. They are generally incorporated in amounts of 0.05 to 40%, based on the total detergent

Still further optional components include water-soluble and / or dispersible, hydrophobic, colloidal, dirt-suspending celluloses or cellulose derivatives. Methyl cellulose, for example Methocel 15 and carboxymethyl cellulose (CMC), are particularly effective. Polyvinyl alcohol is also effective, especially when washing cotton and synthetic fibers such as nylon, dacron and shark-treated cotton. The additional dirt-suspending substance can be contained in an amount of up to 4%, based on the total detergent.

In addition to the above-mentioned ingredients, fillers such as sodium sulfate 20 sodium chloride and the like can also be incorporated. The amount is in the range of up to 40% of the total detergent.

The detergent is produced by conventional methods, for example by spray drying a crutcher mixture of surfactant, builder, filler etc. without volatile constituents, such as perfume or constituents which are otherwise damaged by spray drying, such as peroxygen bleach, e.g. B. sodium perborate. Ingredients of this type are preferably mixed in afterwards. As previously mentioned, the cationic plasticizer / ethoxylated amine mixture is easily dried with the dried particulate

The surfactant is mixed mechanically, which is more than sufficient to obtain a homogeneous product. A typical procedure is as follows. Water is added to a crutcher, followed by sequential anionic surfactant, sodium silicate optional ingredients, if used, such as Satintone # 2, and fillers, such as sodium sulfate and builder salt. The Crutcher mixture is added prior to the addition of the builder, e.g. B. Sodium tripolyphosphate 30 heated to about 60 ° C. The solids content of the crutcher mixture before spray drying is 55 to 65%. Spray drying is carried out in a manner known per se by pumping the hot mixture from the crutcher into a spray tower, in which the mixture passes through a spray nozzle into a hot evaporation atmosphere. Bleaching agents and other materials to be added subsequently are added to the cooled, dried detergent suitably, for example by simple mixing, built-in 35 When the detergent is used, a sufficient amount is added to the washing program to achieve a concentration of cationic plasticizer in the washing medium of 1.5 to 8.0 g / 3500 g of laundry, within a range of 21 ° C to a boiling point of about 100 ° C. In this context it is found that under "cold" washing a washing temperature of up to 21 ° C, under "warm" Washing a temperature of about 21 ° C to the boiling point is understood. Certain types of aliphatic quaternary ammonium compounds, although they are relatively ineffective as plasticizers, are nevertheless fairly effective antistatic agents in the detergents according to the invention, especially since they are physically compatible with the anionic surfactants in the liquid environment. In general, these materials include the ethoxylated and / or propoxylated quaternary ammonium compounds of the following formula 45 50 CH3 (R7) m - N - (R®) n R9 +

X 55 where R? and R & each represents an ethoxy or propoxy group, m and n are integers from 1 to 50 and may be the same or different, R ^ represents an alkyl group having 14 to 24 carbon atoms and X is as defined above. Compounds of this type include (a) methyl bis - (2-hydroxyethyl) cocoammonium chloride, a -7-

Liquid with 7S% active ingredients in isopropanol / water as a solvent, commercially available as Ethoquad c / 12, Armak, and as Variquat638 from Sherex Chemical Co.; (b) Ethoquard c / 23, a compound which is the same as or similar to (a) but has 15 moles of ethylene oxide (R7 and R ^, m and n each 15) and is obtainable with 95% active ingredient; (c) methylbis- (2-hydroxyethyl) octadecylammonium chloride, a liquid 5 with 75% active ingredients in isopropanol / water as solvent, available as Ethoquad 8/12, Armak, and (d) the same (similar) compound as in (c), however, which contains 15 moles of ethylene oxide (each at R7 and R ^ .munds 15 each), a liquid with 95% active ingredients, which is commercially available as Ethoquad 18/15, Armak. These substances can be used in amounts up to about 10 wt % of the total mass must be present.

The following examples are intended to illustrate the invention. All parts and percentages are based on weight 10.

Bgjgpiri IA. And Example 1B A) 88 parts of powdery Arosurf TA (dimethyldistearylammonium chloride) were heated to 90 ° C., whereby a fluid melt was obtained. 8 parts of Ethomeen T-25.1 part of calcium silicate and 3 parts of 15% moisture were added to this melt. The mixture was stirred well and then cooled to room temperature to obtain a white solid. The solid was then ground to a powder (0% pass on a 238 mm sieve sieve; less than 10% pass on a 0.149 mm sieve opening). The product is similar to the original arosurf powder. B) Example 1A was repeated except that 8 parts of an ethoxylated fatty alcohol was used as the non-20 ionic dispersant in place of the ethoxylated amine.

To 100 g of this composition was added 4.1 g (4.1%) of the cationic powder of Example 1A or 4.5 g 40 (43%) of the cationic powder of Example 1B to give detergents 2A and 2B, respectively

For each detergent 2A and 2B, softening and antistatic properties were tested. The results are summarized in Table A. The softening was carried out under the following condition »! determined: a load of textiles was washed in a Maytag washing machine at 37.8 ° C in 64.41 water (150 ppm) with 100 g detergent (total weight approx. O, 68 kg). The textiles consisted of four terry towels, three 45 38.10 x 38.10 cm strips each of the following 7 types of textile: Bankm, Dacron double knitwear (DDK), Dacron / cotton blend (64/35), cotton percal, acetate jersey (AJ), Nylon jersey and dacron polyester, simple jersey (DSK), as well as 10 strips of three differently soiled fabrics (spinach on 50/50 dacron / cotton; sebum on DDK and Piscatawayton on 50/50 dacron / cotton). After a single wash, the fabric load was dried in a conventional tumbler for about 30 minutes and left to cool for about 2 hours. Six experienced panelists evaluated the softness of the towels treated with each test formulation using one of two methods: To test the test detergents, each of the four towels was evaluated against each of the towels treated with each of the other test detergents (in four separate groups) was rated from softest to hardest; or each of the four towels was rated for each test detergent on a scale of 1 (no softening) to 10 (her-55 drastic softening), and an average of the four values was " softness number " taken. In the previous test (softening in comparison), the total number of first places (1 point), second places (2 points), third places (3 points) etc. were added up for each detergent, -8-

In the latter test (movable scale), the average softness number of each tester was averaged with the softness number awarded by the other testers, whereby a single softness number was kept and the softening effect was better the higher the number, each of these methods was statistically as significant and reliable ». 5 To determine the antistatic effect, the built-up electrostatic charge (volt) was applied to strips of 4 different textiles (Dacron / cotton (65/35); Dacron; double-faced jersey fabric (DDK); acetate jersey (AJ) and banion polyester), which like washed as described above. Each three washed and machine-dried strips of the four different types of textile were attached to a holding frame. A small strip of wool attached to the outer edge of a rotating round holding device was rotated on the device in contact with the textile strip for 5 seconds. The temperature was maintained at 21.1 Ins at 22.2 ° C and the relative humidity at 21%. The potentials of each textile tea (3 different strips) were averaged together, then the average potentials of the four different textiles were averaged to get the "electrostatic number". The lower the electrostatic number, the better the anti-static effect of the detergent. Electrostatic numbers of little more than about 5 kilovolts (KV) are generally regarded as very good in IS and perceived by the consumer as a non-existent electrostatic charge. 20 sample QUAT g / wash 25 2B (comparison) 3.96 2A (invention) 3.62 30

Example 1 was repeated with the exception that the mixture of dimethyldistearylammonium chloride, the adduct of tallow amine and 15 moles of ethylene oxide, calcium silicate and water was stirred and a 40 extrusion soap press (extruder) was fed to the inlet from which it was extruded in pasta or spaghetti form. For example, adding the spaghetti or pasta to the spray-dried detergent gave results similar to those of Composition 2A. 45 example!

Example 1A was repeated, except that the following ethoxylated tertiary amines were used instead of Ethomeen T / 25: (a) polyoxycthylene- (5) -octadecylamine 50 (b) polyoxyethylene- (5) -talgamine (c) Polyoxyethylene (10) tallow amine (d) Polyoxyethylene (15) tallow amine (e) Polyoxyethylene- (5) - (hydrogenated) - tallow amine (f) Polyoxyethylene (15) - (hydrogenated) tallow amine. -9- 55

Na2SÜ3 and water were added to 4% of the cationic plasticizer / ethoxylated amine plasticizer dispersant according to Example 1A. They had excellent washing power and softening properties.

Example 6 4.5 g of the cationic plasticizer / ethoxylated amine powder from Example 1A was subsequently added to the powdery spray-dried detergent from Example 2. Additional improvements in softening were achieved (softness number on the sliding scale: 9-10).

The following examples show the preparation and use of the cationic-nonionic combination in prill form.

Example, 7,500 kg of dimethyldistearylammonium chloride containing about 4% water were heated to 90 ° C. to form a melt. 25 kg of Ethomeen T / 25 were added to this hot melt. This mixed melt was then sprayed downwards from the upper end of a tower of approximately 24 m (diameter of approximately 15 m). At the same time, cold air at a temperature of approximately 10 ° C. was sprayed upwards (ie in countercurrent to the falling spray or spray mist) with a Speed of about 850 m ^ per minute passed. The solidified product was collected on the tower floor. The product particles are white, free-flowing, generally round and solid. They have a porous surface (pockmarked appearance). The bulk density of the prilled product is about 037g / cm3

Example 8

To 95.5 g of the detergent from Example 2 (without the particles from Example 1A) were added 4.0 or 4.5 g of the prill bodies from Example 7.

Example 9

Each of the preceding examples was repeated once more, however, the cationic plasticizer of the cationic-ethoxylated amine mixture was replaced by the following substance: (a) dimethylditalgammonium methosulfate; (b) dimethyl di (hydrogenated) tallow ammonium chloride; (c) l-methyl-l-tallowamidoethyl-2-tallowimidazolinium methosulfate; (d) l-methyl-l-oleylamidoethyl-2-oleylimidazolinium methosulfate -10-
