Description

DESCRIPTION The invention relates to particulate detergent and softening agent compositions which are capable of ensuring improved softening, cleaning action, antistatic properties and prevention of dirt re-precipitation, especially when washing in a machine, in the textiles treated therewith.

Thus, compositions which can be used to machine-wash or wash textiles 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 are commercially available. The interactions between anionic surfactant (the most frequently used type of surfactant) and cationic plasticizers, in particular those of the quaternary di- (lower-res) -alkyl-di (higher) -alkylammonium salt type, are also well known in the patent literature. This interaction often leads to the formation of invisible precipitates, which are held within or on the washed textile part. Discoloration or other aesthetically unpleasant effects are mostly unavoidable. The net result is often a reduction in the effective amount of anionic surfactant available, since loss of anionic surfactant is the main consequence of this interaction.

Although the most effective types of cationic quaternary ammonium plasticizers (such as the above-mentioned quaternary compounds disubstituted with higher alkyl)

fertilize, e.g. Distearyldimethylammonium chloride) 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 promote undesirable cationic / anionic interaction. As a general rule, softening and antistatic effects require at least about twice as much cationic surfactant.

US Pat. No. 3,325,414, which deals primarily with detergents whose foamability is controlled, discusses the cationic / anionic problem and associated adverse effects in detail. In addition, this patent indicates that certain quaternary ammonium compounds belonging to the class of cationic agents are generally unstable when heated and in contact with alkaline builders, the instability being evidenced by the development of strong amine odors and undesirable coloration. The compositions of this patent are limited to the use of quaternary ammonium halides with only one higher alkyl group, and the structural formula given for the cationic compounds is accordingly restricted. Cationic compounds of this type are noticeably inferior to the di (higher) alkyl compounds, at least as far as the textile softening effect 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 proposed 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 information can be found in U.S. Patents 4,113,630,4,196,104 and 4,272,386. U.S. Patent No. 4,230,590 discloses heavy duty laundry detergents containing conventional builders, primarily 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 composition essentially in homogeneously dispersed discrete particles.

Heavy duty detergents are disclosed in U.S. Patent 4,298,480, the compositions of which are similar to those in the previous paragraph, except that cellulose ether is excluded

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

In GB 2 133 813A further improvements of these compositions were achieved, for example less greasy stains or stain-like discolouration by the cationic plasticizer, by adding discrete particles (for example prill products) of a mixture of the cationic to the anionic surfactant and the builder and homogeneously mixed therewith Amine plasticizer built with non-ionic surfactant.

The prior art also includes US Pat. Nos. 4,339,335, 4,326,971, 416, 811, 4,411,803, 4,450,085, and 4,414,129, all of which disclose granular or powder detergents and softeners.

Although the above-mentioned detergent compositions containing surfactant / soap and cationic plasticizer 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 stains, cleaning power, antistatic and dirt-preventing properties for textiles washed with them in cold or warm water.

Methods for the preparation of these compositions and their use are also shown.

To achieve the object of the invention, compositions according to the independent claims are proposed; the dependent 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 about 2 to 20 wt .-%, based on the composition, (i) of a cationic amine plasticizer such as (a) quaternary aliphatic di - ((lower) Cr to C4) -alkyl-di ((higher) C14-bis C24) 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)), wherein 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 the above-mentioned GB 2 133 813A, the addition of the cationic material intimately mixed with non-ionic organic surfactant in flake, granulate or the like form has the advantage that the stains or discoloration of the textiles after drying are significant be mitigated. Since the non-ionic surfactant acts as a dispersant to improve the uniform dispersion of the cationic softener and thus the uniform deposition of the same on the treated textiles, the non-ionic surfactant also contributes to the uniform softening and inhibition of the re-precipitation of dirt, especially not -phosphate-containing formulations.

However, the non-ionic ethoxylated fatty alcohol serving as a dispersing agent does not per se improve the degree 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 textiles, i.e. 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 has to meet numerous different criteria when it contains the "non-active" dispersants in the subsequently added softening particles, e.g. Prill products of the GB application. The softening compound must also act as a dispersant for the fine-particle cationic fabric softening compound when the prill 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.e. not be reactive with the cationic fabric softener. It must also be processable into prill body, granulate or other discrete particle form and be compatible with the surfactant, builder and other constituents of the detergent composition. This compound, which is intended to replace the non-ionic surfactant which acts as a dispersant, is also said to contribute to the antistatic behavior of the overall detergent composition or at least not to adversely affect it.

It has now been found that when the nonionic surfactant serving as the dispersant, namely the ethoxylated

Alcohol, replaced by an equivalent amount of an ethoxylated tertiary amine, the total amount of the cationic softener (in the form of its mixture with the ethoxylated amine) can be substantially reduced 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 plasticizer cationic amine, which is usually the most costly ingredient in the formulation, has a very significant one Cost savings result.

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) -Ci4- to C24), N, N-di ((lower) -Ci to C4) -alkylammonium salts with water-solubilizing anions, e.g. 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

R1 +

R - N - R2 X-_ R3

are defined, wherein R and R1 each represent an alkyl radical having 14 to 24, preferably 14 to 22 carbon atoms;

R2 and R3 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: distearyl dimethyl ammonium chloride, di (hydrogenated) tallow dimethyl ammonium chloride, ditallow dimethyl ammonium chloride, distearyl dimethyl ammonium methyl sulfate and di (hydrogenated) tallow dimethyl ammonium methyl sulfate.

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

R4 CH2CH2NH - C - R6

be defined in which R4 represents a lower alkyl group having 1 to 4, preferably 1 to 3, carbon atoms; R5 and R6 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 tradename Varisoft 475 as a liquid with 75% active ingredients in isopropanol as a solvent; and 1-methyl-l-oleylamidoethyl-2-oleylimidazolinium methyl sulfate, which is also available from Sherex Chemical Co under the tradename Varisoft 3690 with 75% active ingredient in isopropanol as solvent.

Mixtures of this cationic fabric softener can be used including mixtures of quaternary ammonium salt and imidazolinium salt.

The ethoxylated amine compounds which are useful in the present invention are the ethoxylated tertiary amines which have the following formula

(CH2CH20) xH

R-N

Ns (CH2CH20) yH

can be reproduced, wherein R is an organic substituent ent of the fat series, and x and y stand for positive numbers whose sum x + y is about 2 to about 15.

Preferred examples of the organic substituent R de 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 x + y is preferably about 5 to about 15. Specific examples of suitable R groups include the decyl, dodecyl, steaiyl, tallow, (hydrogenated) tallow, myristoyl, oleyl and the like radicals, which they generally derive from the corresponding higher fatty acid. Mixtures of various alkyl chain lengths are commonly used, e.g. Cn-to-Qs, C14-to-CI6, C16-to-CI8, Cig-to-Qo and so on. Steayl, tallow and hydrogenated tallow compounds are readily available commercially, such as the Ethome series from Armak Chemical Co., e.g. 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. VaronicT-215 (R = tallow, x + y = 15); VaronicT-210 (R = tallow, x + y = 10); Varo-nic U215 (R = mixture of cetyl / stearyl, x + y = 15); Varonic U205 (R = Celyl / steaiyl mixture, 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 a dual function: as a dispersant for the cationic textile softener, showing an effect equivalent to that of the non-ionic surfactant (the ethoxylated fatty alcohol) in the compositions of the British patent application mentioned above, and also as such softening active butt joint. Because of the advantage of this additional softening, the total amount of cationic textile softener subsequently added to the powdered detergent composition can be reduced with the same total content of active softening compounds (cationic softening agent plus ethoxylated amine), 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

The cationic-non-ionic mixture is preferably produced in prilled form. The prills or prill products or prill bodies are produced 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 molten cationic compound. A typical cationic substance is Arosurf TA-100 (Dimethyldisteaiylammoniumchlo-rid), a material that, 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 too

grind the desired particle size and subsequently add the other detergent ingredients.

Alternatively, the cationic and the ethoxylated amine, when combined, can 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 to extrusion (preferably) or another method, e.g. Peletting, granulating, punching or pressing. Processing can be carried out, for example, by rolling (roll milling), although this is not essential, and then extruding using a conventional pelotone 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, thread 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.e. 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 around 0.9 to 1.3 g / cm3. The squat dimensions are about 4 mm long and wide and 0.2 mm thick, 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 percent by weight of ethoxylated amine, based on the weight of the cationic plasticizer, is provided. The ethoxylated amine should preferably be used in amounts of 5 to 15%, with about 8 to 9% being 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 S04H, S03H, COOH and P04H and an alkyl or an alkyl group with about 8 to 22 carbon atoms in the alkyl radical. Suitable surfactants are anionic surfactant salts with alkyl substituents containing 8 to 22 carbon atoms, such as, for example: water-soluble sulfated and sulfonated anionic alkali metal and alkaline earth metal surfactant salts and surfactant salts which have a higher alkyl radical than the hydrophobic part, such as the salts of higher ones Alkyl substituted mono- or polynuclear aiyl sulfonates with about 8 to 18 carbon atoms in the 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 pentapropylene benzenesulfonate; Alkali salts of sulfated condensation products of ethylene oxide, for example containing 3 to 20 and preferably 3 to 10 moles of ethylene oxide, with aliphatic C8 to C18 alcohols or with alkylphenols having 6 to 18 carbon atoms in the alkyl group, e.g. Sodium nonylphenolpentaet hoxamer sulfate and sodium lauryl alcohol triethoxamer sulfate; Alkali salts of saturated alcohols containing about 8 to 18 carbon atoms, e.g. Sodium lauryl sulfate and sodium steaiyl sulfate; Alkali salts of esters of higher fatty acids with (lower) alkylene sulfonic acids, e.g. Fatty acid esters of the sodium salt of isethionic acid; Fatty ethanol amide sulfates; Fatty acid amides of amino-alkylsulfonic acids e.g. Lauric acid amide from taurine; Alkali salts of hydroxyalkanesulfonic acids with 8 to 18 carbon atoms in the alkyl group, e.g. 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 is ensured, according to the following relationship:

% Concentration = 1.5 KS + 5,

where KS represents the percentage concentration of the cationic plasticizer.

This ensures the minimum excess of anionic surfactant needed for optimal overall cleaning, softening, etc. Effect of the overall product is required.

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 (i.e. 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 C8 to Ci3 fatty alcohols such as tridecyl alcohol with 3 to 100 moles of ethylene oxide; Ci6 to Qg alcohols with 11 to 50 moles of ethylene oxide; Ethylene oxide adducts with monoesters of polyvalent, e.g. 6-valent, alcohol; Condensation products of polypropylene glycol with 3 to 100 moles of ethylene oxide; the condensation products of alkyl (Q to C2o, straight chain or branched) phenols with 3 to 100 moles of ethylene oxide and the like.

Suitable amphoteric surfactants generally include those which have both an anionic group and a cationic group and a hydrophobic organic group, which is preferably a higher aliphatic radical having 10 to 20 carbon atoms. Examples of these are the N- (long-chain) Alkylamino carboxylic acids and the N- (long chain) alkyliminodicarboxylic acids as described in U.S. Patent No. 3,824,189.

The compositions according to the invention 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 can be used, 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 Na20 / SiO2 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 you will produce phosphate-containing or phosphate-free detergents. Sodium carbonate is particularly effective for the latter. Another material that provides good washing effects is metakaolin, which is usually obtained by heating kaolinite (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 kaolinite. In US Pat. No. 4,075,280, columns 3 and 4, and in "The Chemistry and Physics of Clays and Allied Ceramic Materials", Grimshaw (4th edition, Wiley-Interscience, pages 723-727), explanations of kaolin and Metakaolin. Metakaolin is also the subject of US Ser. Nos. 905 622 and 905 718, the knowledge of which is assumed here. The metakaolin also appears to be useful as a plasticizer. The most effective metakaolines appear to be those that react best with sodium hydroxide to form zeolite 4A, as described in U.S. Patent 3,114,603, which describes these materials as "reactive kaolin". According to the explanations in the sources given, metakaolin is an aluminosilicate. 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 brighteners, 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 Calco-cid Blue 2G as Bluing agent. The brightener can be incorporated in amounts up to about 1% based on the total composition, while bluing agents can be included in the range up to about 0.1%, preferably up to about 0.01% of the composition. Bluing agents such as polar brilliant blue (Polar Brilliant Blue) may be present in the cationic prill product. In any case, an effective amount need only be minimal.

Other optional ingredients include bleach, 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 about 4 to 6 "members" in the ring are described in US Pat. No. 3,325,414. All the bleaching agents of the oxygen and chlorine type mentioned are completely compatible with the compositions according to the invention and have good resistance in the presence of the anionic and cationic components. They are generally incorporated in amounts from about 0.1 to 45% by weight of the solid constituents or from about 0.05 to about 40%, based on the total detergent composition.

Still further optional components include water-soluble 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 soil-suspending substance can be contained in an amount of up to about 2%, based on the total solids and up to about 4%, based on the total detergent composition.

In addition to the ingredients mentioned above, fillers such as sodium sulfate, sodium chloride and the like can also be incorporated. The amount is in the range of up to about 40% of the total composition. 5 The detergent composition is prepared by conventional methods, for example by spray drying a Crutcher mixture of surfactant, builder, filler etc. without volatile components such as perfume or components which are otherwise damaged by spray drying such as peroxygen to bleach, e.g. Sodium perborate. Components of this type are preferably mixed in afterwards. As mentioned previously, the cationic plasticizer / ethoxylated amine mixture is simply mechanically dry blended with the dried particulate surfactant, which is more than sufficient to obtain a homogeneous product. A typical procedure is as follows: water is added to a crutcher, followed by an anionic surfactant, sodium silicate, optional ingredients if used such as Satintone # 2 and fillers such as sodium sulfate and builder salt. The Crutcher-20 mixture is mixed before adding the builder, e.g. Sodium tripoly phosphate, heated to about 60 ° C. The solids content of the Crutcher mixture before spray drying is about 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 and other materials to be added subsequently are incorporated into the cooled, dried detergent composition in a suitable manner, for example by simple mixing.

3o When the detergent composition is applied, a sufficient amount is added to the wash program to achieve a cationic softener concentration in the wash medium from about 1.5 to 8.0 g / 3500 g of laundry, within a range of about 21 ° C to 35 to the boiling point of about 100 ° C. In this context it is found that "cold" washing means a washing temperature of up to 21 ° C, and "warm" washing is a temperature of 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 invention, especially since they are physically compatible with the anionic surfactants in the liquid environment. In general, these materials include the 45 ethoxylated and / or propoxylated quaternary ammonium compounds of the following formula

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 1B

A) 88 parts of powdery Arosurf TA (Dimethyldisteaiylammoni umchlorid) 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 moisture were added to this melt. The mixture was stirred well and then cooled to room temperature. A white solid substance was obtained. The solid substance was then ground to a powder (less than 10% pass on No. 8 sieve corresponding to 2.38 mm 0% pass; less than 10% pass on US 100 sieve 0.149 mm diameter). The product is similar to the original arosurf powder.

B) Example 1A was repeated with the exception that 8 parts of an ethoxylated fatty alcohol were used as the non-ionic dispersant at parts 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 (4.5%) of the cationic powder of Example 1B, whereby compositions 2A and 2B were obtained respectively . Softening and antistatic properties were tested for each composition 2A and 2B. The results are summarized in Table A. The softening was determined under the following conditions:

A load of textiles was washed in a Maytag washing machine at 37.8 ° C (100 ° F) in 64.41 (17 gallons) of water (150 ppm) with 100 g of detergent (total weight about 0.68 kg) [1.5 pounds]). The textiles consisted of four terry towels, each with three 38.10 x 38.10 cm (15 "xl5") strips of the following 7 types of textile: Banlon, Dacron double knitwear (DDK), Dacron / cotton blend (64/35 ), Cotton percale, 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 Piscataway clay 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 compositions, each of the four towels was evaluated against each of the hand towels treated with each of the other test compositions (in four separate groups) was rated from softest to hardest; or each of the four towels was rated on a scale from 1 (no softening) to 10 (excellent softening) for each test composition and an average of the four values was taken as the "softness number". 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 composition, the lowest total corresponding to the best softening effect. 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 obtained and the softening effect was better the higher the number. Each of these methods has proven to be statistically significant and reliable.

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 banlon polyester) washed as described above. 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 outside edge of a rotating circular holding device was rotated on the device in contact with the textile strip for 5 seconds. The temperature was maintained at 21.1 to 22.2 ° C (70-72 ° F) and the relative humidity at 21%. The potentials of each textile part (3 different strips) were averaged together, then the average potentials of the four different textiles were averaged to obtain the "electrostatic number". The lower the electrostatic number, the better the anti-static effect of the detergent. Electrostatic numbers less than about 5 kilovolts (kV) are generally considered to be very good and are perceived by the consumer as a lack of electrostatic charge.

Example 7

500 kg of dimethyldisteaiylammonium chloride with a content of about 4% water were heated to 90 ° C. to form a melt. 25 kg of Ethc io meen T / 25 were added to this hot melt. This mixed melt was then sprayed down from the top of an approximately 24 m tower (approximately 15 m in diameter). At the same time, cold air at a temperature of about 10 ° C was directed upward (i.e. countercurrent to the falling spray or mist) at a speed 15 of about 849 m3 (30,000 cubic feet) per minute. The solidified product was collected on the tower floor. The product particles are white, free-flowing, generally round and firm. They have a porous surface (pockmarked appearance). The bulk density of the prill product is about 0.37 g / cm3.
