The polyalkylene oxide backbone can have a linear or branched structure. The polyalkylene backbone can be extended by condensation with suitable connecting molecules such as, but not limited to, dicarboxylic acids or diisocyanates. The main chain comprises a plurality of hydrophobic side chains. Preferred hydrophobic side chains comprise C4-25 alkyl groups, polypropylene and polybutylene units, vinylesters of saturated monocarboxylic acid containing from 1 to 6 carbon atoms, C1-6 alkyl ester of acrylic or methacrylic acid; or mixtures thereof, The hydrophobic side chains may comprise a concentration of vinyl acetate greater than 50% by weight of those hydrophobic side chains, more preferably, greater than 70%, and most preferably, greater than 90% by weight of those hydrophobic side chains; or the hydrophobic side chains comprise a butylacrylate concentration of about 0% to 10% by weight of those hydrophobic side chains, more preferably, about 1% to 7% by weight, and most preferably, about 2% by weight. 5% by weight of these hydrophobic side chains. The hydrophobic side chains can also comprise modifying monomers including, for example, styrene, N-vinyl pyrrolidone, acrylic acid, methacrylic acid, maleic acid, acrylamide, vinylacetic acid or vinyl formamide. More preferably, the hydrophobic side chains can also comprise from about OJ% to 5% by weight of said hydrophobic side chains, more preferably from about 0.5% to 4% by weight and, most preferably, from about 1% by weight. 3% by weight of said hydrophobic side chains, or the hydrophobic side chains comprise N-vinylpyrrolldone from about OJ% to 10% by weight of said hydrophobic side chains, more preferably from about 0.5% to 6% by weight and, with the highest preference of about 1% to 3% by weight of said hydrophobic side chains.

The polymer useful in the present invention may have the general formula: wherein X and Y are terminal units independently selected from H or C1-C6 alkyl; Z is a terminal unit independently selected from H or the radical C portion (ie, a carbon-containing fragment derived from the radical initiator attached to the nascent chain as a result of a recombination process); each R1 is independently selected from methyl or ethyl; each R2 is independently selected from H or methyl; each R3 is independently selected from C1-C4 alkyl; and each R4 is independently selected from pyrrolidone or phenyl groups. The values of m, n, o, p and q are selected in such a way that the molecular weight of the polyethylene oxide chain is from about 1000 to 12000 g / mol, as described above, from about 3000 to 9000 g / mol or from 4000 to 6000 g / mol. The suspended groups generally comprise at least 50% by weight, at least 55% by weight or at least 60% by weight of the polymer up to 98% by weight, 95% by weight or 90% by weight of the polymer. The polymer useful herein usually has a MW of 1000 g / mol, 2500, 7500 or 10,000 g / mol at 150,000, 100,000, 45,000 or 34,000 g / mol. Preferably, the polymer is made by a free radical-mediated graft polymerization reaction which is carried out with a sufficient amount of initiator radical at a temperature of less than 100 ° C, more preferably less than 85 ° C and with the maximum preference less than 75 ° C. The temperature will generally be 60 ° C, 65 ° C or approximately 70 ° C. While polymers having insertion temperatures greater than 100 ° C have been described above, the lower temperatures and kinetics described herein produce a primary polymer structure. While these polymers continue to be "randomly grafted polymers," the lower insertion temperature increases the total / average size of each individual grafted chain and the grafted chains are more spaced apart from each other in the polymer. In general, polymers formed in this manner at the lower insertion temperatures are more hydrophilic and have comparatively higher turbidity points in water than polymers formed at the higher insertion temperatures, even if the same reactants and materials are used. premiums, and if the final PM and the weight ratio of the main chain: grafted chain weight index is the same. The polymer may have from about 0.5 to about 1.5, from about 0.6 to about 1.25 or from 0.75 to 1.1 insertion points per monomeric unit backbone, ethylene oxide unit, polyethylene glycol unit, etc., as appropriate to that. specific polymer. The number of insertion points per monomer unit main chain (or other appropriate unit for that polymer) is determined by NMR spectroscopy analysis of the net polymer, since the solvents can interfere with the NMR measurement. The polymer may also contain a plurality of hydrolysable portions, such as ester or amide containing parts which may be partially or fully hydrolyzed. The degree of hydrolysis of the polymer is defined as% mole of hydrolysable parts which have been hydrolyzed in the corresponding fragments. In general, the degree of hydrolysis of the polymer will not be greater than 75 mol%, from about 0 mol% to about 75 mol%, from 0 mol% to about 60 mol% or from about 0 mol% to 40 mol%. In other embodiments, the degree of hydrolysis ranges from 30 to 40 mol% or from 0 to 10 mol%. The polymers can be totally or partially hydrolyzed. The degree of hydrolysis of the polymer is defined as the percentage of moles of ester linkages that have been saponified into the corresponding carboxylate and alcohol derivatives. Preferably, the degree of hydrolysis of the polymer will not be greater than 75% of moles, more preferably not greater than 60%, and most preferably not greater than 40%. The polymer is present in the auxiliary detergent composition in an amount of 0.001 to 90% by weight, usually 0.01 to 25% by weight or 0.01 to 15% by weight. b) Auxiliary ingredients The auxiliary detergent material comprises any of the auxiliary ingredients listed below. Generally, the auxiliary composition of the invention will comprise a surfactant, and generally this will comprise an anionic surfactant. Although high levels of surfactant may be incorporated, eg, from 10 to 60% by weight, it may be preferred that the level of the anionic surfactant in the auxiliary composition, especially when the anionic surfactant comprises alkenylbenzenesulfonate, is less than 9% by weight in based on the total weight of the auxiliary composition. The level of surfactant can be from 0.5% by weight to 8.5% by weight, or 1% by weight to 7% by weight, based on the total weight of the auxiliary composition.

Preparation of the auxiliary detergent composition The auxiliary detergent composition can be obtained by agglomeration, spray drying, vacuum freeze drying (lyophilization), or extrusion process. In an embodiment of the invention, the auxiliary detergent composition comprises a spray-dried particle. The spray drying processes for making particles of the detergent composition are prepared by first forming a fluid composition conventionally referred to as slurry and the slurry is subjected to a drying step, generally by spray, to produce the particulate detergent component.

It has been found that the grease cleaning polymers of the invention are particularly advantageous in processes of this type because unexpectedly it has been discovered that they reduce the viscosity of the slurry. Generally, when preparing slurries for spray drying, it is advantageous to produce the slurry as concentrated as possible, which contains the lowest possible water level, so that the drying process is more efficient and profitable and it is required to eliminate less water from the slurry. . However, the process is limited by the viscosities produced by the aqueous solution of the surfactant and other components in the slurry, since the slurry must have a sufficiently low viscosity that allows it to be sprayed in the spray-drying tower. Surprisingly, it has been found that the use of the above-defined fat cleaning polymers decreases the viscosity of the slurry by allowing lower water levels, such as less than 30% by weight or even less than 28% by weight. or even less than 25% by weight in the slurry, to obtain a slurry that can be sprayed. Preferably, the weight ratio of the polymer to the total surfactant in the slurry is from 100: 1 to 10: 1, more preferably from 50: 1 to 20: 1. Spray drying is carried out by conventional means (generally using hot air drying, although spray cooling may also be useful). Typically, it will be done in a spray-drying tower using a high-pressure spray nozzle (eg, 6000-7000 kPa). Centrifugal disk atomizers can also be used. In general, the raw materials provided by the suppliers in solution or dispersion in water are premixed, and the solids are subsequently added to form the slurry. In an alternative embodiment, the auxiliary detergent composition of the invention is prepared by an agglomeration process wherein the polymer and the auxiliary detergent component are mixed and granulated in a high speed mixer / granulator or in a fluidized bed agglomerator. Suitable processes are described in U.S. Pat. no. 5,133,924 and in patent no. W097 / 22685. The inventors of the present have discovered that the presence of the polymer, especially when it is mixed with other liquid components to form the agglomerate, such as a surfactant, produces an unexpected benefit since it promotes mixing between the solid and liquid components, they are generated agglomerates with much more uniform particle sizes, and the production of too large particles is considerably reduced. In another embodiment of the invention, the auxiliary detergent compositions are prepared by spraying a solution of the polymer in a solvent onto a solid auxiliary detergent material. The solid auxiliary detergent material can be a raw material or preprocessed particles such as spray dried particles, agglomerates, extruded products or combinations thereof. The solvent may be water, but advantageously comprises a more viscous auxiliary detergent component such as a surfactant. The present invention is extremely advantageous for allowing the spraying of more viscous auxiliary detergent components because the polymer reduces the viscosity of these components, allowing spraying or promoting better mixing with the solid auxiliary detergent material because finer spraying can occur in comparison with spraying the same liquid auxiliary detergent component in the absence of the polymer. Preferred auxiliary detergent components for spraying in this manner comprise surfactants which may be anionic, cationic, nonionic, amphiphilic, or amphoteric or mixtures thereof, as described below. The invention is especially useful for enabling or facilitating the spraying of nonionic or anionic surfactants by first forming a premix. Generally, this premix for spraying on the solid detergent material will comprise a weight ratio of polymer to surfactant of 1: 100 to 2: 1, more generally 1:50 to 1: 10. Generally, the weight ratio of the solid detergent material for spraying will be from 100: 1 to 10: 1, more generally from 50: 1 to 15: 1. The particles produced will generally have a bulk density of at least 300 g / l or at least 400 g / l and up to 1000 g / l or 900 g / l or less (according to the measurements of the method described below). The final density of the particles and compositions herein can be measured by a simple technique which involves dispensing a quantity of the granular material into a container whose volume is known, measuring the weight of the material and reporting the density as grams per liter. The method that is used in the present allows the material to flow towards the measuring vessel by the force of gravity, without pressure or other compression in the measuring vessel.

The density measurements should be made at room temperature. The granular material whose density is measured must be at least 24 hours old and must be kept at room temperature for 24 hours prior to the test. It is convenient to have a relative humidity of 50% or less (obviously, any agglomerate present in the material should be undone smoothly before the test is performed.) The sample of material is allowed to flow through a funnel mounted on a filling hopper and (No. 150; Seedburo Equipment Company, Chicago, Illinois) in an Ohaus cuvette of known weight and volume (No. 104; Seedburo) The top of the cuvette is located approximately 50 mm from the bottom of the funnel, and fill the bucket until it overflows, using a spatula or a ruler to scrape the upper part of the bucket, without vibration or shock, in order to level the material, filling the bucket completely and precisely. The density can be reported as grams per liter.This operation is performed twice more and the bulk density is reported as an average of the three measurements.The relative error is approximately 0.4%. In accordance with the invention, the auxiliary detergent particles are processed further to incorporate them into conventional granules, such as agglomerates or extruded products, or to mix them dry with other particulates or liquid components for spraying. When the auxiliary detergent composition is further processed by agglomeration or extrusion, any solid particulate in a conventional granulation process is totally or partially replaced by the particles of the auxiliary detergent composition of the present invention. Conventional and known suitable granulation processes include the use of a disk granulator, fluidized bed, Schugi mixer, Lódige grid mixer, rotary drum or other low energy mixers, maromerizer or spheronizer; compaction processes, including extrusion, optionally with spheronization or formation of maros (granules), and tablet formation; when melt-binding agents are used to form granules and pellets using a Sandvik Roto Former equipment; and in high shear processes in which the mixers have a high speed shaking and cutting action. Suitable mixers are well known to those skilled in the industry. Suitable processes are described in the patent literature: an example of an agglomeration process is described in U.S. Pat. no. 5,133,924 (Appel). An example of a suitable fluidized bed agglomeration process is described, for example, in patent no. W097 / 22685 (Dhanuka). Suitable extrusion processes are described, for example, in patent no. WO97 / 03181 (EP-A-840780) (Henkel) or EP-A-518888 (Henkel). The auxiliary detergent composition is suitable for use in a detergent composition, such as a laundry detergent composition; that is, to make a fully formulated detergent composition. Alternatively, the auxiliary detergent composition is suitable for use in combination with a detergent composition, such as a laundry detergent composition, that is, as an additive to a detergent composition that is already fully formulated.

The composition generally has a mean particle size of 250 to 2000 microns, preferably 350 to 1500 microns, or generally no more than 10% by weight of the composition has a particle size of less than 50 microns, or generally no more of 10% by weight of the composition has a particle size greater than 1200 microns.

As described above, detergent compositions comprising the particles made by the process of the invention will comprise at least some of the commonly used auxiliary detergent materials, such as agglomerates, extruded products, other spray-dried particles having a composition different from those of the invention, or dry aggregate materials. Conventionally, the surfactants are incorporated into agglomerates, extruded products, spray dried particles together with solid materials, usually additives, and these can be mixed with the spray dried particles of the invention.

Fabric Integrity agents are typically polymeric components that are deposited on the surface of the fabric and prevent damage to it during the washing process. Preferred fabric integrity agents are hydrophobically modified celluloses. This type of celluloses reduces the abrasion of the fabrics, improves the interaction between the fibers and reduces the loss of dye from the fabric. A preferred hydrophobically modified cellulose is described in W099 / 14245. Other fabric integrity agents are polymeric or oligomeric components preferably obtained by means of a process comprising the step of condensing imldazole and epichlorohydrin. A preferred auxiliary component is a salt. Preferably, the detergent composition comprises one or more salts. The salts can function as alkalinity agents, buffers, additives, coadditives, scale inhibitors, fillers, pH regulators, stabilizers, and combinations thereof. Normally, the detergent composition comprises (by weight of the composition) from 5% to 60% salt. Preferred salts are alkali metal salts of aluminate, carbonate, chloride, bicarbonate, nitrate, phosphate, silicate, sulfate, and combinations thereof. Other preferred salts are the alkaline earth metal salts of aluminate, carbonate, chloride, bicarbonate, nitrate, phosphate, silicate, sulfate, and combinations thereof. Especially preferred salts are sodium sulfate, carbonate, bicarbonate, silicate and sulfate, and combinations thereof. Optionally the salts of alkali metals or alkaline earth metals can be anhydrous. A preferred auxiliary component is a soil release agent. Preferably, the detergent composition comprises one or more soil release agents. Soil release agents are typically polymeric compounds that modify the surface of the fabric and prevent redeposition of dirt therein. Preferred soil release agents are copolymers, preferably block copolymers comprising one or more terephthalate units. Preferred soil release agents are copolymers synthesized from dimethylterephthalate, 1,2-propylglycol and polyethylene glycol coated with methyl. Other preferred soil release agents are the anionically coated polyesters. A preferred additional ingredient is a soil suspending agent. Preferably, the detergent composition comprises one or more agents for suspending dirt. The preferred soil suspending agents are the polymeric polycarboxylates. Especially preferred polymers are polymers derived from acrylic acid and from maleic acid and copolymers derived from maleic acid and acrylic acid. In addition to their dirt-holding properties, polymeric polycarboxylates are coadditives useful for washing detergents. Other preferred soil suspending agents are the alkoxylated polyalkyleneimines. Particularly preferred alkoxylated polyalkyleneamines are the ethoxylated polyethyleneamines or the ethoxylated-propoxylated polyethyleneimines. Other preferred soil suspending agents are represented by the formula: bls ((C2H50) (C2H40) n) (CH3) -N + -CxH2x-N + - (CH3) -bis ((C2H40) n (C2H50)) I wherein n = from 10 to 50 and x = from 1 to 20. The soil suspending agents represented by the above formula can optionally be sulphated or sulphonated. A preferred additional ingredient is a tinting agent or dye. These are formulated to improve the whiteness of laundry by imparting a very faint shade on the surface of the fabrics during the washing process which can help to mask the color of residual or redeposited yellow spots. Unlike fluorescent brighteners that act by absorbing ultraviolet light and re-emitting visible light, tonalizing dyes are not usually fluorescent and tonallzan fabrics absorbing light in the visible region of the electromagnetic spectrum. Examples of suitable tinting dyes are set forth in U.S. Pat. no. 3775201 (Colgate) and no. 3762859 (Colgate) and in WO 2005/003274 (Lever), WO 2005/003275 (Lever), WO 2005/003276 (Lever), WO 2005/003277 (Lever) and WO 2005/014769 (Ciba). The preferred materials are: acid violet identified in the color directory (Cl) with the numbers 9, 17, 24 and 49; acid red Identified with the numbers of Cl 4, 14, 17, 18, 27, 88, 103, 150, 151 and 266; acid black identified with the numbers of Cl 1 and 24; acid blue Identified with the numbers of Cl 15, 29, 45, 80, 83, 90 and 113; acid orange identified with the numbers of Cl 7 and 8; direct yellow identified with the number of Cl 8; direct red identified with the numbers of Cl 2, 23 and 81; direct violet identified with the numbers of Cl 5, 7, 9, 11, 13, 51 and 66 and direct blue Identified with the numbers of Cl 1, 34, 70, 71 and 72. Some colored photocatalysts have a double function by acting both as dyes tonallzadores and as catalysts of bleaching by solar action. Preferred materials are sulfonated zinc phthalocyanines, sulfonated aluminum phthalocyanines or mixtures thereof. Tinolux® BBS and Tinolux® BMC products are suitable photocatalysts marketed by Ciba Specialty Chemicals. The main ingredient of Tinolux® BBS is phthalocyanine sulphonated aluminum. The Tinolux® BMC product contains a mixture of aluminum phthalocyanines and sulfonated zinc. The presence of these photocatalysts in the detergent compositican help to mitigate the accumulation of other tinting dyes in the fabrics through a photodegradation mechanism as described in patent no. WO 2005/014769 (Ciba).

SOFTENER SYSTEM The detergent compositiof the invention may comprise softening agents to soften with washing, such as clay and optionally with a flocculant and enzymes. A more detailed specific description of the suitable detergent components can be found in patent no. W097 / 11 151.
