- polyurethane versions of the present invention can be prepared according to the following general scheme.
- the ethoxylated compound from step 1 is dissolved in 1000 ml. of acetonitrile and then cooled to about 10°C. To this solution is added 2.67 moles of tosyl chloride dissolved in 500 ml. of acetonitrile and cooled to 10°C and then 2.9 moles of triethylamine is added. After the reaction is complete, H 2 O is added to decompose the remaining tosyl chloride.
- step 3 To the reaction mixture from step 3 is added 3.4 moles of diethanolamine. After heating for 18 hrs. at 80°C, the reaction mixture is cooled and carefully acidified with HCl to a pH just above 7 and then extracted with ether. The aqueous phase is then extracted with a mixture of ether:acetonitrile (ratio of about 5:2) twice. The aqueous phase is separated and then made basic with 50% NaOH. This aqueous phase is extracted with dichloromethane (2000 ml.). The lower layer is separated and then extracted 3 times with 2000 ml. portions of 1/4 saturated NaCl solution while adding enough 50% NaOH to make the aqueous phase strongly basic (pH of about 11). The lower organic layer is stripped to give the desired aminated compound. Toluene (200 ml.) is added and the mixture stripped again to give the desired aminated monomer.
- the polymer from step 4 is dissolved in methanol and an excess of methyl bromide is passed in. After about 5 hours, the pH is adjusted to about 4 with aqueous HCl and is then allowed to stand overnight to solvolyze the tetrahydropyranyl protecting group. The solution is then neutralized with NaOH and stripped to give the crude polyurethane. This crude polyurethane is dissolved in chloroform and filtered to remove any salts. The chloroform is stripped away to give the desired, largely salt-free polymer.
- the random copolymer versions of the present invention can be prepared according to the following general scheme: The synthesis of one such random copolymer is described as follows:
- Decaethylene glycol monomethacrylate monomer (0.008 moles) and N-(3-dimethylaminopropyl)-methacrylamide monomer (0.011 moles) are dissolved in 40 ml. of acetonitrile.
- the reaction mixture is purged of oxygen by bubbling argon through it.
- a 0.23 g. portion of benzoyl peroxide is separately dissolved in 10 ml. of acetonitrile and similarly purged.
- the reaction mixture is heated to reflux and the benzoyl peroxide solution then added dropwise over 0.5 hours.
- 0.28 g. of azobisisobutyronitrile in 5 ml. of acetonitrile is added to the reaction mixture and heating continued overnight.
- a stream of methyl bromide is then passed through the reaction mixture which is then warmed slightly for 1 hour.
- the desired random copolymer is isolated by stripping off the solvent.
- Quaternized polyethyleneamines and polyethyleneimines can be prepared using standard methods for ethoxylating amines, with subsequent quaternization. Representatiave syntheses of such polyethyleneamines and polyethyleneimines are as follows:
- Tetraethylenepentamine (M.W. 189, 13.5 g., 0.071 moles) was placed in a nominally dry flask and dried by stirring for 0.5 hrs. at 110°-120°C under vacuum (pressure less than 1 mm Hg.). The vacuum was released by drawing ethylene oxide (EO) from a prepurged trap connected to a supply tank. Once the flask was filled with EO, an outlet stopcock was carefully opened to a trap connected to an exhaust bubbler. After 3 hrs. stirring at 115°-125°C, H-NMR analysis indicated the degree of ethoxylation of 1 per reactive site. The reaction mixture was cooled while being swept with argon and 0.5 g.
- EO ethylene oxide
- Diallylamine polymer versions of the present invention can be prepared according to the following general scheme: The synthesis of one such polymer is described as follows:
- Diallylamine (1.7 moles) is dissolved in methanol (160 ml.) under argon and then heated to 45°C. Ethylene oxide is then added for 2.5 hours. Methanol is then removed by heating the reaction mixture to 100°C in vacuo. To the residue is added sodium hydride in mineral oil (6.6 g., 0.165 moles) with stirring until the evolution of hydrogen has ceased. Ethylene oxide is then added until the degree of ethoxylation (n) is about 7.
- the crude ethoxylated diallylamine from step 1 is dissolved in about an equal volume of 1N methanolic NaOH and then methyl bromide is added. This methyl bromide addition is continued until H-NMR analysis shows complete disappearance of the methylene hydrogens adjacent to the tertiary nitrogen. Additional portions of 1 N methanolic NaOH are added as needed to maintain the pH of the reaction mixture at about 9. The methanol is removed, yielding a damp mass. This damp mass is washed with several portions of dichloromethane. The combined washes are concentrated to yield the desired quaternized compound.
- the quaternized monomer from step 2 is mixed with D 2 O (20 ml.) and heated to 95°C under argon for 1 hour. Tertbutylhydroperoxide (25 drops) is then added and the reaction continued at 90°C for 18 hours. Then 20 more drops of the hydroperoxide is added. After heating 3 more days, water is then removed in vacuo (50°-60°C at pressure of 0.1 mm) to yield the crude polymer.
- the cationic compounds for use herein are water-soluble.
- water-soluble preferably means that at least 30g of compound is soluble in 100g of water, at 20°C.
- a water-soluble cationic compound allows to formulate agglomerates which are much more active, i.e. which comprise a greater amount of surfactant, without any significant impact on the solubility of the agglomerate in water, or without increasing its tendency to gel upon contact with water. It is believed that premixing the compound and the surfactant causes to structure the surfactant paste so as to form a dough of a higher viscosity and reduced stickiness. This, in turn allows for the use of a lesser amount of the carrier, and the overall result is an agglomerate of higher activity.
- the agglomerates of the present invention comprise from 10% to 50% by weight of the agglomerate of a surfactant, preferably from 20% to 40%, most preferably from 25% to 35%.
- the agglomerates of the present invention comprise from 10% to 50% by weight of the agglomerate of a carrier, preferably from 20% to 40%, most preferably from 25% to 35%.
- the agglomerates of the present invention comprise from 10% to 50% by weight of the agglomerate of acetate, preferably from 20% to 40%, most preferably from 25% to 35%.
- the agglomerates of the present invention comprise from 0% to 40% by weight of the agglomerate of water soluble cationic compound, preferably from 2% to 30%, most preferably from 3% to 15%.
- a preferred optional ingredient for the surfactant agglomerate is a polymer having a melting point of more than 35°C, preferably of more than 45°C, more preferably of more than 55°C, and most preferably of more than 60°C, including PEGs (poly-ethylene-glycol) for example, most preferred being PEG 4000.
- the agglomerate comprises a surfactant, more preferably a nonionic surfactant, having a melting temperature of less than 35°C, whereby this surfactant having a melting temperature of less than 35°C is likely to melt when the agglomerate is placed in high temperature environment, in which case the addition of the polymer having a melting point of more than 35°C will allow to increase the melting point of the mixture, thus avoiding formation of a liquid phase.
- This polymer is preferably treated during the process for making the agglomerate at the same time as the surfactant, and is preferably present in proportions of at least 3% and up to 20% by weight of the agglomerate, more preferably in proportions of at least 4 and up to 6%.
- Another preferred optional ingredient is a water-soluble salt of citrate so as to further improve the dissolution profile of the agglomerates herein.
- a water-soluble salt of citrate is commercially available and can be used in the present invention. Mixtures of different salts can also be used. It is undesirable that the citrate should introduce any water into the agglomerate, and so a preferred form of the citrate salt is the anhydrous form.
- citrate should be in the closest possible proximity with the surfactant.
- citrate especially in its anhydrous form
- citrate is a hygroscopic material which therefore has a strong tendency to cake, even when packed in moisture protected packages.
- the problem is particularly acute with fine materials which are preferred for use herein.
- zeolites also referred to as zeolites, particularly overdried zeolites.
- the result is a powdery mixture of a water-soluble salt of citrate salt and zeolite, suitable for the manufacture of the agglomerate of the present invention.
- the powdery mixture has improved flowing properties, without significant negatives on the dissolution profile of citrate.
- the powdery mixture can comprise from 1 % to 30% by weight of the mixture of zeolite, and the remainder citrate, or acetate, or a mixture of both. Generally, an amount of 1% to 10% zeolite is sufficient to achieve the desired result.
- These materials can be mixed together with any suitable equipment, and it is preferred to mix these ingredients, i.e. acetate and/or citrate and zeolite at temperature ranging from 10 to 50, preferably from 15 to 30. Indeed, the use of such lower temperature prevents or reduces moisture pick up.
- the citrate has a function in wash as it acts as a builder.
- the agglomerate comprises a mixture of acetate and citrate instead of acetate alone.
- the mixture of citrate and acetate may comprise from 1 up to 100% by weight of citrate, and more preferably from 40 up to 60% by weight of citrate.
- the critical aspect of the process according to the invention is that it must ensure that the acetate is in close proximity with the surfactant in the agglomerate. Such close proximity could not be achieved through dry addition of the acetate with the agglomerate so as to form a final composition. Rather, such close proximity can be achieved by a variety of means which include the two following embodiments.
- the acetate, or a portion thereof is intimately mixed with the surfactant before it is agglomerated with the carrier.
- the acetate is intimately mixed with the carrier before the surfactant is agglomerated with it.
- the surfactant and the carrier are pre-agglomerated, and the acetate is sprayed onto the pre-agglomerate so as to form the final agglomerate.
- Both embodiments can be combined in that a portion only of the acetate can be intimately mixed with the surfactant or the carrier. Then, the surfactant and the carrier and the portion of the acetate are pre-agglomerated, and the remainder of the acetate is finally sprayed onto the pre-agglomerate so as to form the final agglomerate.
- Optional ingredients in the agglomerate can be formulated in a variety of ways, with the exception of the water-soluble cationic compound which must be mixed with the surfactant before the surfactant is mixed with the carrier. If the acetate is also mixed with the surfactant, it is preferred to first mix the surfactant and the water-soluble cationic compound, then the acetate, then to agglomerate that mix with the carrier.
- the process herein includes mixing a fluid (the surfactant) with powders (the acetate, the carrier), a fluid (the surfactant) with a fluid (the water-soluble cationic compound), a powder (the acetate) with a powder (the carrier), and those can be performed by any means which are well know to the skilled person.
- Suitable pieces of equipment to perform those steps include : mixers of the Fukae R FS-G series manufactured by Fukae Powtech Kogyo Co., Japan; this apparatus is essentially in the form of a bowl-shaped vessel accessible via a top port, provided near its base with a stirrer having a substantially vertical axis, and a cutter positioned on a side wall.
- the stirrer and cutter may be operated independently of one another and at separately variable speeds.
- the vessel can be fitted with a cooling jacket or, if necessary, a cryogenic unit.
- mixers found to be suitable for use in the process of the invention include Diosna R V series ex Dierks & Söhne, Germany; and the Pharma Matrix R ex T K Fielder Ltd., England.

- the Littleford Mixer, Model #FM-130-D-12, with internal chopping blades and the Cuisinart Food Processor, Model #DCX-Plus, with 7.75 inch (19.7 cm) blades are two examples of suitable mixers. Any other mixer with fine dispersion mixing and granulation capability and having a residence time in the order of 0.1 to 10 minutes can be used.
- the "turbine-type" impeller mixer, having several blades on an axis of rotation, is preferred.
- the invention can be practiced as a batch or a continuous process.
- acetate is sprayed onto a pre-agglomerate of the surfactant and the carrier (and optionally the water-soluble cationic compound)
- Suitable sprayable solutions comprise 30g/l to 60g/l of acetate, preferably 40g/l to 50g/l of acetate.
- the acetate can be dissolved in a variety of liquid carriers, including water and polyethylene glycol.
- any spraying equipment can be used, and it is preferred that the agglomerate is dried after it has been sprayed with the solution of acetate. Again, any conventional drying equipment can be used for this purpose.
- the surfactant agglomerate Once the surfactant agglomerate has been formed, it can be desirable to subject it to a heating and/or drying step, followed by a cooling step. This will enable the removal of excess moisture.
- the surfactant - or surfactant/water-soluble cationic compound premix - is mixed with the carrier, it is desirable to bring the surfactant - or surfactant/water-soluble cationic compound premix - to a viscosity of about 15000 to 35000 cps, preferably 20000 to 25000 cps. This can be achieved by controlling the temperature of the surfactant or surfactant/water-soluble cationic compound premix. This will enable a more convenient mixing of the surfactant or surfactant/polymer premix with the carrier.
- the dissolution profile of the surfactant agglomerate can be measured as follows :
- compositions in which the agglomerate can be formulated
- the agglomerates according to the present invention can be formulated in granular or tablet detergent compositions.
- these detergent compositions can comprise a variety of ingredients including but not limited to other surfactants, builders, chelants, bleaches, bleach activators, soil release polymers, suds controlling or boosting agents, pH adjusting agents, enzymes, enzyme stabilizers, perfumes, brighteners, dye transfer inhibiting agents, and the like.
- At least 40%, preferably at least 60%, most preferably at least 90% of the surfactant is incorporated by means of the agglomerate.
- the surfactant agglomerates can be simply mixed with the rest of the ingredients that are in particulate form or in turn may be subjected to further process steps of spraying liquids and coating with fine powders.
- the modular approach is based on the manufacturing of particles highly specific in one or at most two ingredients of the formulation which are then mixed at the desired ratios to form the finished products.
- These particles being highly specific in the ingredient they are to deliver, can be used in a wide range of products without need to be modified.
- These particles can be prepared with an optimal combination of ingredients that maximize their properties independently of full finished product formulations.
- Detergent tablets can be prepared simply by mixing the solid ingredients together and compressing the mixture in a conventional tablet press as used, for example, in the pharmaceutical industry.
- the detergent tablets can be made in any size or shape and can, if desired, be coated.
- the particulate materials (other than the agglomerates of the invention) used for making the tablet can be made by any particulation or granulation process.
- An example of such a process is spray drying (in a co-current or counter current spray drying tower) which typically gives low bulk densities 600g/l or lower.
- Particulate materials of higher density can be prepared by granulation and densification in a high shear batch mixer/granulator or by a continuous granulation and densification process (e.g. using Lodige® CB and/or Lodige® KM mixers).
- Other suitable processes include fluid bed processes, compaction processes (e.g. roll compaction), extrusion, as well as any particulate material made by any chemical process like flocculation, crystallisation sentering, etc.
- Individual particles can also be any other particle, granule, sphere or grain.
- the particulate materials may be mixed together by any conventional means. Batch is suitable in, for example, a concrete mixer, Nauta mixer, ribbon mixer or any other. Alternatively the mixing process may be carried out continuously by metering each component by weight on to a moving belt, and blending them in one or more drum(s) or mixer(s).
- a non-gelling binder can be sprayed on to the mix of some, or all of, the particulate materials.
- Other liquid ingredients may also be sprayed on to the mix of particulate materials either separately or premixed. For example perfume and slurries of optical brighteners may be sprayed.
- a finely divided flow aid dustting agent such as zeolites, carbonates, silicas
- the tablets may be manufactured by using any compacting process, such as tabletting, briquetting, or extrusion, preferably tabletting.
- Suitable equipment includes a standard single stroke or a rotary press (such as Courtoy®, Korch®, Manesty®, or Bonals®).
- Tablets prepared should preferably have a diameter of between 40mm and 60mm, and a weight between 25 and 100 g.
- the ratio of height to diameter (or width) of the tablets is preferably greater than 1:3, more preferably greater than 1:2.
- the compaction pressure used for preparing these tablets need not exceed 5000 kN/m 2 , preferably not exceed 3000 kN/m 2 , and most preferably not exceed 1000 kN/m 2 .
- Suitable non-gelling binders include synthetic organic polymers such as polyethylene glycols, polyvinylpyrrolidones, polyacrylates and water-soluble acrylate copolymers.
- the handbook of Pharmaceutical Excipients second edition has the following binders classification: Acacia, Alginic Acid, Carbomer, Carboxymethylcellulose sodium, Dextrin, Ethylcellulose, Gelatin, Guar gum, Hydrogenated vegetable oil type I, Hydroxyethyl cellulose, Hydroxypropyl methylcellulose, Liquid glucose, Magnesium aluminum silicate, Maltodextrin, Methylcellulose, polymethacrylates, povidone, sodium alginate, starch and zein.
- binders also have an active cleaning function in the laundry wash such as cationic polymers, i.e. ethoxylated hexamethylene diamine quaternary compounds, bishexamethylene triamines, or others such as pentaamines, ethoxylated polyethylene amines, maleic acrylic polymers.
- cationic polymers i.e. ethoxylated hexamethylene diamine quaternary compounds, bishexamethylene triamines, or others such as pentaamines, ethoxylated polyethylene amines, maleic acrylic polymers.
- the non-gelling binder materials are preferably sprayed on and hence have an appropriate melting point temperature below 70°C and preferably below 50°C so as not to damage or degrade the other active ingredients in the matrix.
- Most preferred are non-aqueous liquid binders (i.e. not in aqueous solution) which may be sprayed in molten form.
- they may also be solid binders incorporated into the matrix by dry addition but which have binding properties within the tablet.
- the non-gelling binder materials are preferably used in an amount within the range from 0.1 to 15% of the composition, more preferably below 5% and especially if it is a non laundry active material below 2% by weight of the tablet.
- the tablets may be coated so that the tablet does not absorb moisture, or absorbs moisture at only a very slow rate.
- the coating is also strong so that moderate mechanical shocks to which the tablets are subjected during handling, packing and shipping result in no more than very low levels of breakage or attrition.
- the coating is preferably brittle so that the tablet breaks up when subjected to stronger mechanical shock.
- the coating material is dissolved under alkaline conditions, or is readily emulsified by surfactants. This contributes to avoiding the problem of visible residue in the window of a front-loading washing machine during the wash cycle, and also avoids deposition of undissolved particles or lumps of coating material on the laundry load.
- Water solubility is measured following the test protocol of ASTM E1148-87 entitled, "Standard Test Method for Measurements of Aqueous Solubility".
- Suitable coating materials are dicarboxylic acids.
- Particularly suitable dicarboxylic acids are selected from the group consisting of oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, suberic acid, azelaic acid, sebacic acid, undecanedioic acid, dodecanedioic acid, tridecanedioic acid and mixtures thereof.
- the coating material has a melting point preferably of from 40 °C to 200 °C.
- the coating can be applied in a number of ways. Two preferred coating methods are a) coating with a molten material and b) coating with a solution of the material. In a), the coating material is applied at a temperature above its melting point, and solidifies on the tablet. In b), the coating is applied as a solution, the solvent being dried to leave a coherent coating.
- the substantially insoluble material can be applied to the tablet by, for example, spraying or dipping. Normally when the molten material is sprayed on to the tablet, it will rapidly solidify to form a coherent coating. When tablets are dipped into the molten material and then removed, the rapid cooling again causes rapid solidification of the coating material.
- substantially insoluble materials having a melting point below 40 °C are not sufficiently solid at ambient temperatures and it has been found that materials having a melting point above about 200 °C are not practicable to use.
- the materials melt in the range from 60 °C to 160 °C, more preferably from 70 °C to 120 °C.
- melting point is meant the temperature at which the material when heated slowly in, for example, a capillary tube becomes a clear liquid.
- a coating of any desired thickness can be applied according to the present invention.
- the coating forms from 1% to 10%, preferably from 1.5% to 5%, of the tablet weight.
- Such tablet coatings are very hard and provide extra strength to the tablet.
- the fracture of the coating in the wash is improved by adding a disintegrant in the coating.
- This disintegrant will swell once in contact with water and break the coating in small pieces. This will improve the dissolution of the coating in the wash solution.
- the disintegrant is suspended in the coating melt at a level of up to 30%, preferably between 5% and 20%, most preferably between 5 and 10% by weight. Possible disintegrants are described in Handbook of Pharmaceutical Excipients (1986).
- Suitable disintegrants include starch: natural, modified or pregelatinized starch, sodium starch gluconate; gum: agar gum, guar gum, locust bean gum, karaya gum, pectin gum, tragacanth gum; croscarmylose Sodium, crospovidone, cellulose, carboxymethyl cellulose, algenic acid and its salts including sodium alginate, silicone dioxide, clay, polyvinylpyrrolidone, soy polysacharides, ion exchange resins and mixtures thereof.
- the used compaction force will be adjusted to not affect the strength (Diametral Fracture Stress), and the disintegration time in the washing machine.
- This process may be used to prepare homogenous or layered tablets of any size or shape.
- the tablets further comprises an effervescent.
- Effervescency as defined herein means the evolution of bubbles of gas from a liquid, as the result of a chemical reaction between a soluble acid source and an alkali metal carbonate, to produce carbon dioxide gas, i.e. C 6 H 8 O 7 + 3NaHCO 3 ⁇ Na 3 C 6 H 5 O 7 + 3CO 2 ⁇ + 3H 2 O
- Tablets can also be used in a method of washing which comprises the preparation of an aqueous solution of a laundry detergent for use in a front-loading washing machine, the front-loading washing machine having a dispensing drawer and a washing drum, wherein the aqueous solution of laundry detergent is formed by the tablet which is placed in the dispensing drawer before water is passed through the dispensing drawer so that the tablet is dispensed as an aqueous solution of a laundry detergent, the aqueous solution subsequently being passed in the washing drum.
- the surfactant agglomerate comprises an anionic surfactant together with an acetate in combination with any other structurant, whereby these components are brought in close proximity by use of a process producing a high shear force such as extrusion.
- a surfactant agglomerate has a high activity, while having satisfactory processability, such satisfactory processability being provided by hardness and low stickiness of the paste obtained.
- the structurant used may for example be zeolite, silicate, or a mixture of these. It should be noted that satisfactory processability is obtained with surprisingly low levels of acetate, preferably anhydrous sodium acetate, preferably less than 10% per weight of the agglomerate.
- the agglomerate also preferably comprises more than 40% per weight of anionic surfactant, more preferably more than 50 % per weight.
