The polyalkylene oxide main chain may be of straight or branched structure.

The polyalkylene backbone may be extended by condensation to suitable connecting molecules including, but not limited to, dicarboxylic acids and / or diisocyanates.

The backbone comprises a plurality of C4-25 late-chain alkyl groups, polypropylene and polybutylene units, saturated monocarboxylic acid vinyl esters containing from 1 to 6 carbon atoms, acrylic or methacrylic acid C1-6 alkyl ester, or mixtures thereof Hydrophobic side chains may comprise vinyl acetate in an amount greater than 50%, more preferably greater than 70% and most preferably greater than 90% by weight of said hydrophobic side chains, and / or hydrophobic side chains comprise. acrylate debutylates in an amount from about 0.1% to 10%, more preferably from about 1% to 7%, and most preferably from about 2% to 5%, by weight of said hydrophobic side chains.

The polymer for use in the present invention may have the following general formula: <formula> formula see original document page 7 </formula>

wherein XeY are independently selected terminal units of C 1 -C 6 alkyl, Z is an independently selected terminal unit H or radical moiety C (i.e., a carbon-containing fragment derived from the radical initiator linked to the growing chain as a result of a recombination process), each R1 is independently selected from methyl and / or ethyl, each R2 is independently selected from H and / or methyl, each R3 is independently selected from C1-C4 alkyl, and each R4 is independently selected from pyrrolidone and / or phenyl groups. The value dem, η, o, ρ eq is selected such that the molecular weight of the polyethylene oxide main chain is about 1,000 to 12,000 g / mol as described above, or about 3,000 to 9,000 g / mol, or from 4,000 to 6,000 g / mol.

Hanging groups typically comprise at least 50%, or even at least 55%, or at least 60% by weight of the polymer and generally up to 98%, or 95%, or 90% by weight of the polymer. The polymer useful for the present invention typically has a MW of 1,000 g / mol, or 2,500, or 7,500 or 10,000 g / mol to 150,000, or up to 100,000, or up to 45,000 or 34,000 g / mol. Preferably, the polymer is produced by a radical graft polymerization reaction carried out with a suitable radical initiator at temperatures below 100 ° C, more preferably below 85 ° C and most preferably below 75 ° C. Typically, the temperature will be from 60 ° C or 65 ° C, or about 70 ° C. Although polymers having graft temperatures above 100 ° C have previously been shown, the lower temperatures and kinetics of the present invention result in a significantly different primary structure of the polymer. Although these are still "random graft polymers", the lower graft temperature increases the overall / average size of each individual grafted chain, and the grafted chains show greater spacing across the entire polymer. Therefore, polymers formed at lower graft temperatures are generally more hydrophilic and have comparatively higher water mist points than polymers formed at higher graft temperatures, even when the same reagents and raw materials are used, and even if the final PM and the main chain: grafted chain weight ratio are the same. The polymer may be from about 0.5 to about 1.5, or from about 0.6 to about 1.25, or from 0.75 to 1.1 grafting points per monomer unit, ethylene oxide unit or polyethylene glycol unit, among others, of the main chain, as is suitable for that individual polymer. The number of graft points per main chain monomer unit (or other unit, as appropriate for that polymer) is determined by NMR spectroscopic analysis of the pure polymer as solvents may interfere with NMR measurement.

The polymer may further contain a plurality of hydrolysable moieties, such as ester or amide containing moieties, which may be partially or fully hydrolyzed. The degree of polymer hydrolysis is defined as the molar percentage (mol%) of hydrolysable moieties that have been hydrolyzed to the corresponding fragments. Typically, the degree of polymer hydrolysis will not be greater than 75 mol%, or from about 0 mol% to about 75 mol%, or from 0 mol% to about 60 mol%, or from about 0 mol%. mol% to 40 mol%. In other embodiments, the degree of hydrolysis is from 30 mol% to 40 mol%, or from 0 mol% to 10 mol%.

b) Auxiliary Ingredients

The detergent auxiliary compound material comprises any of the auxiliary ingredients listed below. Typically, the auxiliary composition of the invention will comprise a surfactant and will generally comprise an anionic surfactant. Although high surfactant contents may be incorporated, for example from 10% to 60% by weight, it may be preferred that the anionic surfactant content present in the auxiliary composition, especially where it comprises alkyl benzene sulfonate, is below. 9% by weight based on the total weight of the auxiliary composition.

The surfactant content may be from 0.5% to 8.5% or from 1% to 7% by weight based on the total weight of the auxiliary composition.

Preparation of Detergent Auxiliary Composition

The detergent auxiliary composition may be obtainable and / or may be obtained by agglomeration, spray drying, freeze drying or extrusion process. In one embodiment of the invention, detergent auxiliary composition comprises a spray dried particle. Spray drying processes for the manufacture of the detergent composition particles are first prepared by forming a fluid composition conventionally called pastafluid, which is subjected to a drying step, generally by spray drying, to produce a particulate detergent component.

The grease cleansing polymers of the present invention have been found to be particularly advantageous in this type of process because it has been unexpectedly found to reduce the viscosity of the fluid stock. Generally, when preparing slurries for spray drying, it is advantageous to produce the most concentrated slurries possible, containing the lowest possible water contents, so that the drying process has maximum efficiency and low cost, and cheeses. water needs to be removed from said paste. However, the process is limited by the viscosities produced by an aqueous solution of the surfactant and other components present in the slurry, as it must have a sufficiently low viscosity that it can be sprayed into the spray drying stream. The use of the grease-cleaning polymers defined above has been found to surprisingly decrease the viscosity of the slurry, allowing for lower water contents, such as below 30%, or even below 28%, or even below 25% by weight. said paste, resulting in an atomizable fluid paste. Preferably, the weight ratio of polymer to total surfactant in the slurry is in the range 100: 1 to 10: 1, more preferably 50: 1 to 20: 1.

Spray drying is achieved by conventional means (usually by the use of warm air drying, although spray cooling may also be useful). Generally this will occur in a spray drying torrent using a high pressure spray head (for example from 6,000 to 7,000 kPa). Discorotative atomizers can also be used. Generally, raw materials that are supplied by suppliers in solution or dispersion in water are premixed, and solids are subsequently added to form slurry.

In an alternative embodiment, the detergent auxiliary composition of the invention is prepared by an agglomeration process wherein the polymer and detergent auxiliary component are mixed and mixed into a high speed mixer / granulator or a fluidized bed agglomerator. Suitable processes are described in US5133924 and WO97 / 22685. The present inventors have found that the presence of the polymer, particularly when mixed with other liquid agglomerate forming components, such as surfactant, produces an unexpected benefit by promoting mixing between solid and liquid components, which generates agglomerates with much more homogeneous particle sizes. , and significantly reduces particle production of too large a size.

In another embodiment of the invention, detergent auxiliary compositions are prepared by spraying a solvent dopolymer solution onto a solid detergent auxiliary material. The solid detergent aid material may consist of raw materials, or preprocessed particles such as spray-dried, agglomerated or extruded particles, or combinations thereof. The solvent may be water but advantageously comprises more viscous detergent auxiliary compound components such as surfactant. The present invention is highly advantageous in allowing the spraying of more viscous detergent auxiliary compounds, as the polymer decreases the viscosity of that component, allowing spraying and / or promoting better mixing with the solid detergent aid as the production of a spray is enabled. compared to spraying the same auxiliary component of liquid detergent in the absence of the polymer.

Preferred spray detergent auxiliary compounds in this manner comprise surfactants which may be anionic, cationic, nonionic, amphiphilic or amphoteric, or mixtures thereof, as described hereinbelow. The invention is particularly useful for allowing / facilitating the spraying of nonionic and / or anionic surfactant by first forming a premix. Generally, such a spray premix for spraying on solid detergent material will comprise a polymer to surfactant ratio in the range 1: 100 to 2: 1, more typically from 1:50 to 1:10. Generally, the weight ratio of solid detergent to spray material will be in the range of from 100: 1 to 10: 1, more generally from 50: 1 to 15: 1.

The particles produced will generally have an apparent density of at least 300 g / l, or at least 400 g / l, and up to 1,000 g / l, or 900 g / l, or below (as measured by the method described Next). The final density of the particles and compositions of the present invention can be measured by a simple technique which involves dispensing a quantity of granular material into a known volume container by measuring the material weight and recording the density in grams / liter. The method used in the present invention allows material to flow into the gravity measuring container, and without pressure or any compaction on the measuring container. Density measurements need to be made at room temperature. The granular material whose density is being measured must be at least 24 hours after its production and must be kept at room temperature for 24 hours prior to the test run. It is convenient for the relative humidity to be 50% or less. Of course, any lumps present in the material need to be gently undone prior to testing. The material sample is allowed to flow through a funnel mounted in a fill hopper (# 150; Seedburo Equipment Company, Chicago, Illinois, USA) into an Ohaus container of known volume and weight (# 104; Seedburo). The top of the container is positioned about 50 mm from the bottom of the bottom, said container being filled until it overflows. A spatula or other straight-edge instrument is then passed over the top of the container without vibration or impact to level the material to completely fill said container. The weight of the material in the container is then measured. Density can be recorded in g / L. Two repetitions are made, and apparent density is recorded as an average of three measurements. Relative error is about 0.4%.

In another embodiment of the invention, the detergent auxiliary particles are further processed for incorporation into conventional granules, such as agglomerates or extrudates, and / or their dry mixing with other particulate and / or perspiration liquid components. When the detergent auxiliary composition is further processed by agglomeration or extrusion, any solid particulate in a conventional granulation process is wholly or partially replaced by the detergent auxiliary composition particles of the present invention. Known, conventional and suitable granulation processes include the use of tray degranulator, fluidized bed, Schugi mixer, log-cup mixer, rotary drum mixer or other low energy mixers, marumerizer or spheronizer, compaction, including extrusion, optionally with spheronization or marumerization, and tableting where, when fusion binding agents are used, nugget and pellet formation is used in a Sandvik Roto Former, as well as high shear processes where the mixers have high stirring speed and cutting action. Suitable mixers are well known to those of skill in the art.

Suitable processes are described in the patent literature, an example of which agglomeration process is described in US5133924 (Appel). An example of a suitable fluidized bed agglomeration process is described, for example, in WO97 / 22685 (Dhanuka). Suitable extrusion processes are described, for example, in WO97 / 03181 (EP-A-840780) (HenkeI) or EP-A-518888 (Henkel). Auxiliary detergent composition is suitable to be incorporated into a detergent composition, such as a laundry detergent composition, i.e. to produce a full formulation detergent composition. Alternatively, the detergent auxiliary composition is suitable for use in combination with a detergent composition as a laundry detergent composition, that is, as an additive to a ready-made detergent composition already completed.

The composition typically has an average particle size of 250 micrometers to 2,000 micrometers, preferably 350 to 1,500 micrometers and / or typically no more than 10% by weight of the composition, has a particle size of less than 50 µm. micrometers and / or typically no more than 10% by weight of the composition has a particle size greater than 1,200 micrometers.
