Description

The invention relates to detergents, in particular detergents. and plasticizer compositions capable of are improved softening of the textiles treated with it, Cleaning effect, antistatic properties as well as preventing dirt re-precipitation, especially when washing in a washing machine.

Compositions that allow textiles to be used simultaneously machine wash and wash them in considerable Measure can soften and is therefore suitable for use are well known in a washing program and distributed in the trade. Also well known in the Patent literature is the temporary interaction between anionic surfactant (the most commonly used type of surfactant) and cationic plasticizers, especially those of the type quaternary di- (lower) -alkyl-di (higher) -alkylammonium salts. This interaction often leads to the formation of invisible ones Precipitation inside the washed textile part or be held on it. Discoloration or others Mostly, aesthetically unpleasant effects are not avoidable. The net result is often a decrease the effective amount of available anionic surfactant, because the loss of anionic surfactant is the main consequence of this Interaction is.

Although the most effective types are cationic quaternary ammonium plasticizers (such as those above mentioned quaternary disubstituted with higher alkyl Connections, e.g. B. distearyldimethylammonium chloride) in Presence of anionic surfactant, builder etc. in the Wash cycle can be effective, the amount that is for effective softening is required, usually in the same range as the amounts that are undesirable cationic / favor anionic interaction. As a general  The rule is that for softening as for antistatic effects at least about twice as much cationic surfactant is required is.

In US Patent 33 25 414, which deals mainly with detergents deals, whose foamability is controlled, that cationic / anionic problem and associated adverse Effects discussed in detail. In addition, in this Patent noted that certain in the class quaternary ammonium compounds covered by cationic agents generally when heated and in contact with alkaline builders are unstable, increasing the instability by developing strong amine smells and unwanted ones Coloring shows. The compositions of this patent are on the use of quaternary ammonium halides with only limited to a higher alkyl group, accordingly limited is also the given structural formula for the cationic compounds. Cationic compounds of these Species are noticeably inferior to the di (higher) alkyl compounds, at least as far as the textile softening effect is concerned.

The problem of intolerance to cationic substances in anionic detergents is also used in the US Pat 39 36 537 and 41 41 841 and it is suggested here as an essential component in combination with the cationic compound an organic dispersion inhibitor to use. An important characteristic of this Inhibitors contribute to maximum solubility in water 25 ° C of 50 ppm. Similar information can be found in the US PS's Find 41 13 630, 41 96 104 and 42 72 386. In U.S. Patent 4,230,590 heavy-duty detergents are disclosed, the usual builders, mainly anionic surfactants, cationic plasticizers and contain a mixture of fatty acid soap and cellulose ether. The soap-cellulose ether mixture is in spaghetti, Flake or other form before and is in the composition  essentially in homogeneously dispersed discrete Particles present.

In US-PS 42 98 480 heavy duty detergents are disclosed, the Compositions similar to those in the previous paragraph are excluded with the exception that cellulose ethers is.

In US-PS 43 29 237 heavy duty detergents are disclosed that also similar to that of the two previous paragraphs with the exception that the soap particles are mixed with nonionic surfactant.

In GB 21 33 813A further improvements of this were achieved Compositions, for example less greasy stains or stain-like discoloration due to the cationic Plasticizer by adding in addition to the anionic surfactant and the builder and homogeneously mixed with discrete particles (e.g. prill products) a mixture of the cationic amine plasticizer built in with non-ionic surfactant.

As prior art, the US-PS 43 39 335, 43 26 971, 44 16 811, 44 11 803, 44 50 085 and 44 14 129 to name, all granular or powdered washing and softening agents disclose.

Although the above-mentioned surfactant / soap and cationic Detergent compositions containing plasticizers are desirable softening, antistatic and cleaning properties own, there is a desire for further improvement of these properties while reducing the total cost of the product.

The object of the invention is to provide permanent washing and softening agents to create the improved softness without  Staining, cleaning power, antistatic and the Reprecipitation of dirt preventing properties when washed with them in cold or warm water Ensure textiles. The object of the invention is also Process for the preparation of these compositions and to show their application.

Compositions are used to achieve the object of the invention proposed according to the main claim, the sub-claims define preferred embodiments of the invention.

In general, the compositions of the invention comprise, by weight, about 5 to 40% of a water-soluble, non-soap anionic surfactant, about 10 to 60% water-soluble neutral to alkaline builder salt, and a substantially homogeneously dispersed in discrete particles in this composition intimate mixture of (i) about 2 to 20% by weight, based on the composition, of a cationic amine plasticizer such as (a) quaternary aliphatic di - ((lower) C _{1 to} C ₄ ) -alkyl-di ((higher) C ₁₄ -to C ₂₄ ) -alkylammonium salts, (b) heterocyclic compounds and mixtures of (a) and (b), with (ii) a water-soluble ethoxylated tertiary amine as dispersant / plasticizer (preferably 2 to 50% by weight, based on the weight of the cationic plasticizer (i)), where the concentration of the anionic surfactant in% is at least about (1.5 KS + 5) and where KS represents the concentration of the total plasticizers (i) and (ii).

As described in GB 21 33 813A mentioned above, has the addition of the non-ionic organic surfactant intimately mixed cationic material in flakes, granules or the like form the advantage that the spots or discoloration of the textiles after drying significantly be mitigated. Because the non-ionic surfactant as a dispersant  acts to ensure uniform dispersion to improve the cationic plasticizer and thus the uniform deposition of the same on the treated Textiles, the non-ionic surfactant also contributes to the uniform Softening and inhibiting the reprecipitation of Dirt, especially in non-phosphate formulations at.

The non-ionic ethoxylated serving as dispersant However, fatty alcohol does not per se improve the degree of softening caused by the cationic Textile softener is awarded at. It is not complete clarified why the non-ionic dispersant none Softening increases, but it is believed that the reason is that it is compared to the washed ones Textiles are not substantive, d. H. the non-ionic Dispersant is not bound to them.

There are numerous types and classes of fabric softening agents Known compounds, primarily nitrogen-containing Compounds such as the quaternary ammonium salts and imidazoline salt compounds. Nevertheless, a softening active Connection meet numerous different criteria if they add the "non-active" dispersant in the added softening particles, e.g. B. prill products the GB application. The softening compound must also be used as a dispersant for the fine particles cationic fabric softening compound act when the prill products are added to the wash water, and they must solubilize or disintegrate the prill body convey to the wash bath after addition. This connection must of course, if it should be suitable, compatible, d. H. not reactive with the cationic fabric softener be. You must also in the prill body, granules or other discrete particle shape can be processed and with  the surfactant, builder and other ingredients of the detergent composition be tolerable. This connection that the non-ionic surfactant acting as a dispersant Should replace, should also to the antistatic behavior of the total detergent composition or at least not adversely affect this.

It has now been found that when considered as a dispersant serving non-ionic surfactant, namely the ethoxylated Alcohol, by an equivalent amount of an ethoxylated tertiary amine replaced the total amount of cationic Plasticizer (in the form of its mixture with the ethoxylated Amine) can be significantly reduced without a corresponding reduction in the textiles treated mediated softening and in some cases with improved Softening. There is also no deterioration the antistatic properties of the treated Textiles. So while all of the cleansing, softening, antistatic and anti-reprecipitation Properties are improved or not impaired, has the ability to control the amount of plasticizer to reduce cationic amine, which is mostly the am strongest cost-driving ingredient in the formulation is a very substantial cost saving.

Cationic plasticizers which can be used according to the invention are known per se and belong to the strongly plasticizing type. They include the quaternary N, N-di - ((higher) -C _{14 to} C ₂₄ ), N, N-di ((lower) -C _{1 to} C ₄ ) alkylammonium salts with water-solubilizing anions, e.g. B. halides such as chloride, bromide, and iodide; Sulfate, methosulfate and the like as well as the heterocyclic imides, for example the imidazolinium compounds.

The aliphatic quaternary ammonium salts can expediently have the following structure are defined, wherein R and R ¹ each represent an alkyl radical having 14 to 24, preferably 14 to 22 carbon atoms;
R ² and R ³ each represent a lower alkyl radical having 1 to 4, preferably 1 to 3, carbon atoms,
X is an anion that imparts water solubility or dispersibility including the anions mentioned, chloride, bromide, iodide, sulfate and methosulfate.

To particularly preferred aliphatic quaternary compounds include: distearyldimethylammonium chloride, di (hydrogenated) - tallow dimethyl ammonium chloride, ditallow dimethyl ammonium chloride, Distearyldimethylammonium methyl sulfate and di (hydrogenated) - tallow dimethyl ammonium methyl sulfate.

Heterocyclic imide plasticizers of the imidazolinium type can also be used and have the following structure be defined, wherein R ^{4 represents} a lower alkyl group having 1 to 4, preferably 1 to 3 carbon atoms; R ⁵ and R ^{6 are} each essentially linear higher alkyl groups with about 13 to 23, preferably 13 to 19 carbon atoms and X has the meaning mentioned above. Particularly preferred imidazolinium compounds include: 1-methyl-1-tallowamidoethyl-2-tallow-imidazolinium methyl sulfate, available from Sherex Chemical Co under the trade name VARISOFT 475 as a liquid with 75% active ingredients in isopropanol as a solvent; and 1-methyl-1-oleyl-amidoethyl-2-oleylimidazolinium methyl sulfate, which is also available from Sherex Chemical Co under the trade name VARISOFT 3690 with 75% active ingredient in isopropanol as solvent.

Mixtures of these cationic fabric softeners can be used are 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 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 about 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 about 8 to about 22 carbon atoms, especially about 12 to 20 carbon atoms. The sum of x + y is preferably about 5 to about 15. Specific examples of suitable R groups include the decyl, dodecyl, stearyl, tallow, (hydrogenated) tallow, myristoyl, oleyl and the like residues, which are generally derived from the corresponding higher fatty acid. Mixtures of different alkyl chain lengths are usually used, such as. B. C ₁₂ -bis-C ₁₅ , C ₁₄ -bis-C ₁₆ , C ₁₆ -bis-C ₁₈ , C ₁₈ -bis-C ₂₀ and so on. Stearyl, tallow and hydrogenated tallow compounds are readily available commercially, such as the Ethome series from Armak Chemical Co., 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 of cetyl / stearyl, x + y = 5); and are preferred according to the invention because of their high efficiency and relatively low prices.

According to the invention, the ethoxylated fatty amines have one double function: as a dispersant for the cationic Fabric softeners, showing an equivalent effect like the non-ionic surfactant (the ethoxylated fatty alcohol) in the compositions of the British mentioned above Patent application, and also as softening active per se Nitrogen compound. Because of the benefit of this additional Softening can add up to the total amount of powdered Detergent composition added cationic Fabric softener with the same total content of active softening compounds (cationic plasticizer plus ethoxylated Amine) can be reduced, taking about the same Softening and antistatic effect achieved. It can but also the amount of softening / antistatic granules, prilling bodies etc. be held in the same order of magnitude, then one an additional increase in softening and antistatic Receives effect.

The cationic-non-ionic mixture is preferred  made in prilled form. The "prills" or prill products or prill bodies are liquefied by spray cooling Mixture of the cationic and the ethoxylated Amines made. In the most preferred way of training a liquid ethoxylated amine is used and added to the molten cationic compound. A typical cationic substance is Arosurf TA-100 (dimethylstearylammonium chloride), a material that if it is melted and heated to 90 ° C, a very fluid one Liquid forms. According to another preferred way of training can be the liquid mixture of cationic substance and ethoxylated amine for cooling to room temperature or left where necessary for solidification will. The solid substance can then become the desired one Grind the particle size and add the other detergent ingredients be added.

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 by conventional techniques until it is sufficiently "doughy" or plastic extrusion (preferably) or other method, e.g. B. pelletizing, granulating, punching or pressing. The processing can be carried out, for example, by rolling (roll milling), although this is not essential, and subsequent extrusion using a conventional pelotoneuse or soap extruder 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 Buhlter extruder and the like. The spaghetti extrudate is usually a shape-retaining mass, ie semi-solid and essentially non-sticky at room temperature, which in most cases requires no treatment other than water removal. If necessary, the latter can be carried out using simple drying techniques. The spaghetti are said to have an average length of about 2 to 20 mm (about 95% of them within a tolerance of 0.5 to 20 mm) and an average diameter or width of about 0.2 to 2.00 mm, where a Range of 0.4 to 0.8 mm is preferred. The bulk density of the spaghetti is usually about 0.9 to 1.3 g / cm ³ . The flake dimensions are approximately 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% by weight is ethoxylated Amine, based on the weight of the cationic plasticizer, intended. Preferably, the ethoxylated amine in Amounts of 5 to 15% are used, with about 8 to 9% are particularly preferred.

Conventional surfactants can be used according to the invention, but it is preferred that at least about 90, preferably at least about 95% of the total surfactants are anionic, since these are particularly advantageous in heavy-duty detergents for washing textiles. Anionic surfactants which can be used according to the invention include the water-soluble salts of organic reaction products which have an anionic solubilizing group such as SO ₄ H, SO ₃ H, COOH and PO ₄ H and an alkyl or an alkyl group having about 8 to 22 carbon atoms in the alkyl radical. Suitable surfactants 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 than hydrophobic part, such as the salts of mono- or polynuclear aryl sulfonates substituted with higher alkyl about 8 to 18 carbon atoms in the alkyl group, which may 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 C ₈ -C ₁₈ -alcohols or with alkylphenols which have 6 to 18 carbon atoms in the alkyl group, e.g. B. sodium nonylphenol pentaethoxamer sulfate and sodium lauryl alcohol triethoxamer sulfate; Alkali salts of unsaturated alcohols containing about 8 to 18 carbon atoms, e.g. B. sodium lauryl sulfate and sodium stearyl sulfate; Alkali salts of esters of higher fatty acids with (lower) alkylolsulfonic acids, e.g. B. fatty acid esters of the sodium salt of isethionic acid; Fatty ethanol amide sulfates; Fatty acid amides of aminoalkylsulfonic 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. Hexydecylalphahydroxysodium sulfonate. The anionic surfactant or mixture thereof is advantageously used in the form of its alkali or alkaline earth metal salts. The anionic surfactant is preferably of the non-soap type, but small amounts of soap, for example up to about 35% and preferably 20%, based on the total anionic surfactant can be added to the Crutcher mixture.

The concentration of the non-soap anionic surfactant should preferably be chosen so that an excess over the cationic plasticizer guaranteed according to the following relationship:

% Concentration = 1.5 KS + 5,

where KS is the percentage concentration of the cationic Represents plasticizer.

This will make the minimum excess of anionic surfactant ensures that for optimal overall cleaning, softening, etc., d. H. Effect of the overall product required is.

Smaller amounts of other types of surfactants can be incorporated together with the anionic surfactant, the sum of which in any case does not exceed about 10%, preferably about 2 to 5% of the total surfactant (ie such other surfactants plus non-soap anionic surfactant). For this purpose, the non-ionic surfactants with an organic hydrophobic and a hydrophilic group can be used, which are a reaction product of a solubilizing group such as carboxylate, hydroxyl, amido or amino with ethylene oxide or the polyhydration product thereof, polyethylene glycol. These include the condensation products of C _{8 to} C ₁₃ fatty alcohols such as tridecyl alcohol with 3 to 100 moles of ethylene oxide; Ethylene oxide adducts with monoesters of polyvalent, e.g. B. 6-valent alcohol; Condensation products of polypropylene glycol with 3 to 100 moles of ethylene oxide; the condensation products of alkyl (C _{6 to} C ₂₀ , straight or branched) phenols with 3 to 100 moles of ethylene oxide and the like.

Suitable amphoteric surfactants generally include those  which is both an anionic group and one cationic group and a hydrophobic organic group have, which is preferably a higher aliphatic radical with 10 to 20 carbon atoms. Examples of these are the N- (long-chain) alkylaminocarboxylic acids and the N- (long chain) alkyliminodicarboxylic acids, as described in US Patent 38 24 189.

The compositions according to the invention preferably contain water-soluble alkaline to neutral builder salts in amounts of about 10 to 60% by weight of the total composition. The organic and the inorganic builders including the alkali and alkaline earth phosphates are usable, in particular 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 pyrophosphate, monobasic sodium phosphate, dibasic sodium phosphate, sodium hexametaphosphate; Alkali silicates such as sodium metasilicate, sodium silicates, for example with Na ₂ O / SiO ₂ ratios of 1.6: 1 to 3.2: 1, preferably 1: 6 to 1: 3.4, especially 1: 2 to 1: 3, particularly 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. Sodium carbonate is particularly effective for the latter. Another material which provides good washing effects is metakaolin, which is usually obtained by heating kaolinite (glitter 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 kaolinite. In US-PS 40 75 280, columns 3 and 4 and in "The Chemistry and Physics of Clays and Allied Ceramic Materials", Grimshaw, (4th edition, Wiley-Interscience) pages 723-727, there are explanations about kaolin and metakaolin . Metakaolin is also the subject of US Ser. Nos 905 622 and 905 715, the knowledge of which is assumed here. The metakaolin also appears to be useful as a plasticizer. The most effective metakaolines are apparently those that react best with sodium hydroxide to form zeolite 4A, as described in US Pat. No. 3,114F 603, in which these materials are referred to as "reactive kaolin". According to the explanations in the sources indicated, metakaolin is an aluminum silicate. The metakaolin and / or a zeolite is incorporated in the same amounts as the builder salt, preferably in addition to it, for example zeolite: silicate in a ratio of 6: 1. A particularly advantageous form of metakaolin is available as Satintone No. 2.

Preferred optional ingredients according to the invention include Fragrances such as genie perfume; optical brighteners and bluing agents, which can be dyes or pigments. Suitable Materials for this are, for example, stilbene and tinopal 5BM brightener, especially in combination, as well as direct Brilliant Sky Blue 6B, Solophenyl Violet 4BL, Cibacete, Brilliant Blue RBL and Cibacete Violet B, Polar Brilliant Blue RAW and Calcocid Blue 2G as a bluing agent. The brightener can be present in amounts up to about 1% based on the Overall composition, to be incorporated while bluing in the range up to about 0.1, preferably up to about 0.01% of the composition may be included. Bluing agents such as B. polar brilliant blue (Polar Brilliant Blue) can be present in the cationic prill product be. In any case, an effective amount has to be minimal be.  

Other optional ingredients include bleach, which can be of the type releasing oxygen or chlorine. Oxygen bleaches are, for example, sodium and Potassium perborate, potassium monopersulfate and the like. Chlorine bleach Examples are sodium hypochlorite, potassium dichloroisocyanurate, Trichloroisocyanurate acid and the like. The latter chlorine-releasing bleaches are representative for the large class of water-soluble, organic, dry bleaches known as N-chloroimides including their alkali salts. These cyclic imides with about 4 to 6 "links" in the ring are in US-PS 33 25th 414. All mentioned bleaches from oxygen and chlorine type are with the compositions of the invention fully compatible and feature in the presence of the anionic and cationic components have good resistance. They are generally in amounts of about 0.1 up to 45% by weight of the solid components or from about 0.05 up to about 40%, based on the total detergent composition, built-in.

Still other optional ingredients include water-soluble ones and / or dispersible hydrophobic colloidal dirt-suspending Celluloses or cellulose derivatives. Methyl cellulose, for example methocel and carboxymethyl cellulose (CMC) are particularly effective. Polyvinyl alcohol is also effective, especially when washing cotton and synthetic fibers such as nylon, dacron and resin-treated cotton. The additional dirt-suspending substance can be in up to about 2% based on the total Solids and up to about 4% of the total Detergent composition may be included.

In addition to the ingredients mentioned above, too Fillers can be incorporated such as sodium sulfate, sodium chloride and the same. The amount is in the range up to about 40% of the total composition.  

The detergent composition is made by conventional methods produced, for example by spray drying one Crutcher mixtures of surfactant, builder, filler etc. Without volatile components such as perfume or components that otherwise damaged by spray drying such as peroxygen bleach, e.g. B. sodium perborate. Components this type is preferably mixed in afterwards. As previously mentioned, the cationic plasticizer / ethoxylated amine in a simple way with dry mechanically blended the dried particulate surfactant, which is more than enough to make a homogeneous product to obtain. A typical procedure is as follows: You put water in a crutcher, then the row for anionic surfactant, sodium silicate, optional components, if used such as satintone no. 2 and fillers such as sodium sulfate and builder salt. The Crutch mixture is added before adding the builder, e.g. B. Sodium tripolyphosphate, heated to about 60 ° C. The solids content the crutcher mixture before spray drying is about 55 to 65%. Spray drying is carried out in a manner known per se Way by putting the hot mixture from the crutcher in pumps a spray tower, in which the mixture through a Spray nozzle gets into a hot evaporation atmosphere. Bleaching and other subsequently added materials into the chilled, dried detergent composition in a suitable manner, for example by simple Mix in, built in.

When the detergent composition is applied entered a sufficient amount in the washing program, a concentration of cationic plasticizer in the To achieve a washing medium of approximately 1.5 to 8.0 g / 3500 g of laundry, within a range of about 21 ° C to Boiling point of around 100 ° C. In this context found that under "cold" washing a washing temperature  of up to 21 ° C, under "warm" washing a temperature is understood from about 21 ° C to the boiling point.

Certain types of aliphatic quaternary ammonium compounds, although relatively ineffective as plasticizers, are nevertheless fairly effective antistatic agents in the compositions of the present invention, especially since they are physically compatible with the anionic surfactants in the liquid environment. Generally, these materials include the ethoxylated and / or propoxylated quaternary ammonium compounds of the following formula wherein R ⁷ and R ⁸ each represent an ethoxy or propoxy group, m and n are integers from 1 to 50 and may be the same or different, R ^{9 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 liquid with 75% active ingredients in isopropanol / water as a solvent, which is commercially available as Ethoquad c / 12, Armak and Variquat 638 from Sherex Chemical Co. is available; (b) Ethoquad c / 25, a same or similar compound as in (a), but with 15 moles of ethylene oxide (each R ⁷ and R ⁸ , m and n each 15) and available with 95% active ingredient; (c) methylbis (2-hydroxyethyl) octadecylammonium chloride, a liquid with 75% active ingredients in isopropanol / water as solvent, available as Ethoquad 8/12, Armak, and (d) the same (similar) compound as in ( c), but which has 15 moles of ethylene oxide (each at R ⁷ and R ⁸ , m and n are 15), a liquid with 95% active ingredients, which are commercially available as Ethoquad 18/15, Armak. These substances can be present in amounts up to about 10% by weight of the total composition.

The following examples are intended to illustrate the invention. All parts and percentages are by weight.

Example 1A and Example 1B

A) 88 parts of powdery Arosurf TA (dimethyldistearylammonium chloride) were heated to 90 ° C, using a fluid Received melt. 8 parts of Ethomeen were added to this melt T-25, 1 part of calcium silicate and 3 parts of moisture. The mixture was stirred well and then at room temperature cooled down. A white solid substance was obtained. The firm Substance was then ground to a powder (on U.S. sieve No. 8 corresponding to sieve openings with 2.38 mm 0% passage; on US sieve No. 100 corresponding to 0.149 mm diameter less than 10% pass). The product is similar to the original one Arosurf powder.

B) Example 1A was repeated with the exception that 8 Parts of an ethoxylated fatty alcohol as non-ionic Dispersant used in place of the ethoxylated amine were.

Example 2

It became a heavy duty detergent with the following composition produced:

Component Weight%

Linear tridecylbenzenesulfonate (LTBS) 14.5 sodium tripolyphosphate (NaTPP) 26.0 silicate (1: 2.4) 6.8 Na ₂ CO ₃ 4.8 brightener (stilbene and Tinopal 5BM) 0.34 borax 1.0 methocel 0., 5 carboxymethyl cellulose 0.24 sodium sulfate and water q. s. 100.0 100.0

4.1 g (4.1%) of the cationic powder of Example 1A or 4.5 g (4.5%) given the cationic powder of Example 1B, wherein compositions 2A and 2B were obtained, respectively. At each composition 2A and 2B were plasticized and antistatic properties tested. The results are compiled in Table A. The softening was under determined the following conditions:

In a Maytag washing machine at 37.8 ° C (100 ° F) in 64.4 liters (17 gallons) of water (150 ppm) with 100 g of detergent a load of textiles washed (total weight about 0.68 kg) (1.5 pounds)). The textiles included four terry towels, Three 38.10 × 38.10 cm (15 ″ × 15 ″) strips each of the following 7 types of textile: Banlon, 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 textile load in a usual tumbler for about Dried for 30 minutes and left to cool for about 2 hours calmly.  

Six experienced examiners rated the softness of each Test formulation treated towels after one of two methods: To test the test compositions was each of the four towels opposite each of the towels rated with each of the other test compositions were treated (in four separate groups), and in fact, in order from the softest to the hardest rated; or each of the four towels was for each Test composition on a scale of 1 (no softening) rated to 10 (excellent softening), and there was an average of the four values as "softness number" taken. In the previous test (softening) in comparison) was the for each composition Total number of first places (1 point), second places (2 points), third places (3 points) etc. added up, being the lowest total of the best softening effect corresponded. In the latter test (movable scale) was the average softness number of each tester with the softness number awarded by the other testers averaged to obtain a single softness number and the softening effect is better the higher the number is. Each of these methods has turned out to be statistical proven to be significant and reliable.

To determine the antistatic effect, the built up electrostatic charge (volt) on strips of 4 various textiles (Dacron / Cotton (65/35); Dacron; double-layer jersey fabric (DDK); Acetate jersey (AJ) and Banlon polyester) which have been washed as described above, measured. Three washed and machine dried Stripes of the four different types of textile were made on one Holding frame attached. A small one on the outer edge rotating round holding device attached wool strips left on the device in contact with the textile strip  Rotate for 5 seconds. The temperature was at 21.1 to 22.2 ° C (70-72 ° F) and the relative humidity at 21% held. The potential of each textile part (3 different Strips) were averaged together, then the average potentials of the four different Textiles averaged to the "electrostatic number" receive. The lower the electrostatic number, the more the antistatic effect of the detergent is better. Electrostatic numbers less than about 5 kilovolts (KV) are generally considered very good and by the Consumers as nonexistent electrostatic charge felt.
