The technical field to which the invention relates
The present invention relates to stable, easy to pour, non-aqueous liquid compositions which provide good stain removal and care of color. The present invention also relates to a method of re-mix compositions containing a cellulase composition containing a cationic cellulose polymer.
The level of technology
Currently, consumers want a liquid composition for washing with improved beneficial effects in the care of fabrics, such as improved feeling of fabrics and superior color retention. Cationic cellulose polymers are known in the art to provide beneficial effects in treating tissues, in particular, softness, improved tissue preservation, and therefore, improved fabric care. Cellulose enzymes improve the feel of fabrics and colour by removing the cellulose fibrils from the fiber. Because the beneficial effects of cationic cellulose polymers and cellulase are complementary, there is a strong desire to include them both in a liquid composition for washing. However, the unification of these beneficial effects of the composition of one detergent is extremely problematic because cellulases are known, decompose cationic cellulose polyester�ry. Therefore, liquid compositions, in General, are to avoid combinations of cellulosic polymers and cellulose enzyme. For example, WO2004/056958 describes the sacs containing cationic guar gum in combination with ProcessName and amylase enzymes.
WO 2004/069979 and WO 2007/120547 both describe that inhibitors of enzymes can be used to produce a cationic cellulosic polymers and cellulose enzymes in aqueous detergent compositions. However, such solutions increase the cost and complexity of manufacture. This is due to the cost of an inhibitor of cellulases, but also due to the re-mixing of such compositions in other formulations containing cellulose polymers, leads to the disintegration of the cellulose polymer, as an inhibitor of cellulase diluted to an ineffective level during re-mixing. Even trace amounts of cellulose enzyme, as it has been found to decompose cellulose polymers.
Accordingly, there remains a need for funds for the preparation of liquid compositions with cationic cellulosic polymers and cellulose enzyme, without the collapse of cationic cellulose polymers, or complicating the re-mixing of the product containing cellulose enzyme in a product containing a cellulosic polymer.
Summary of the invention
In accordance with the present invention �predlagaetsja non-aqueous liquid composition, containing: cationic cellulose polymer; and cellulose enzyme; wherein the non-aqueous liquid composition comprises less than 20% by weight of water. The present invention also relates to a method of re-mixing of such non-aqueous liquid compositions, characterized by the fact that this method includes a step of combining non-aqueous composition with another non-aqueous liquid composition containing a polymer based on cellulose.
Detailed description of the invention
The present invention solves the problem of providing a stable composition containing as the cationic cellulosic polymer, and a cellulose enzyme. It was found that by limiting the level of water in the composition, the cellulose activity is inhibited so that it is incapable of decomposing a cationic cellulosic polymer.
If even a trace amount of cellulase present in the aqueous composition, it leads to the disintegration of cellulosic polymers. Therefore, blending of compositions containing cellulose enzyme is either impossible or complicated. This is particularly so because any inhibitors of cellulases, which could be diluted to an ineffective level, if the composition containing cellulase, re-mixed in a fresh composition. By limiting the water level, preferably in re-mixed, and to�echnol compositions the risk of disintegration of the cellulose polymer under the action of cellulose enzyme is eliminated.

The charge density is calculated by dividing the total number of charges in a recurring segment on the molecular weight of the repetitive unit. Positive charges can be located on the frame of the polymers and/or side chains of polymers. The term "cationic cellulosic polymer" also includes amphoteric cellulosic polymers that have a total positive charge at a pH of non-aqueous liquid composition.

The sum of all indices v in each Rx in the specified polysaccharide means an integer from 1 to 30, more preferably from 1 to 20, even more preferably from 1 to 10. In recent
the group in chain T always represents N. Alkyl substitution on anhydroglucose cycles of the polymer may range from 0.01% to 5% per glucose unit, more preferably from 0.05% to 2% on the glucose level of the polymer material. Cationic cellulose may be a small degree of transverse cross-linked with a dialdehyde, such as glyoxal to prevent the formation of lumps, nodules or other agglomerations when added to water at ambient temperatures. Cationic cellulose ethers of the structural formula I also include those that are commercially available and include materials that can be obtained by traditional chemical modification of commercially available materials. Commercially available cellulose ethers of the type of structural formula I include having the INCI name Polyquaternium 10, such as those sold under the trademarks: Ucare Polymer JR 30M, JR 400, JR 125, LR 400 and LK 400 polymers; Polyquaternium 67 such as those sold under the trade name Softcat SK™, all of which are sold Amerchol Corporation, Edgewater NJ; and Polyquaternium 4 such as those sold under the trade Mar�Oh: Celquat N and Celquat L-200, available from National Starch and Chemical Company, Bridgewater, NJ. Other suitable polysaccharides include hydroxyethyl cellulose or hydroxypropyl cellulose, quaternion glycidyl C12-C22alkyl of dimethylammonium chloride. Examples of such polysaccharides include polymers with the INCI names Polyquaternium 24, such as those sold under the trade name Quaternium LM 200 by Amerchol Corporation, Edgewater NJ.
Cationic cellulosic polymer can be modified to become more resistant to disintegration under the action of cellulose enzyme. For example, it was found that reducing the number of unsubstituted anhydroglucose links yields a cationic cellulosic polymer, is less sensitive to enzymatic degradation. It is believed that this is caused by the breakage of a chain enzyme, occurring mainly between adjacent unsubstituted anhydroglucose links. Thus, cationic cellulose polymers, including cationic hydroxyethyl cellulose and cationic hydroxypropyl cellulose having a high degree of molar substitution, as has been found, are more resistant to disintegration under the action of cellulose enzymes.
Molar substitution is the average number of substitutions on anhydroglucose duplicate link in the cellulose skeleton. Likewise, cationic hydroxyethyl and hydrox�of proposalwas, molar ratio is the average number of moles ethylene oxide and/or propylene oxide, are reacted with each anhydroglucose duplicate link in the cellulose skeleton. Each repeating unit has three hydroxyl groups available for reaction with ethylene oxide or propylene oxide. However, the resulting hydroxyethylene/hydroxyproline groups also have a hydroxyl group available for further reaction with ethylene oxide or propylene oxide. Therefore, the molar substitution can be above 3.
Cationic cellulose, including cationic hydroxyethyl cellulose and hydroxypropyl cellulose having a degree of substitution of more than 1.34, the also exhibit increased resistance to disintegration under the action of cellulose enzyme. The degree of substitution is the average number of hydroxyl groups anhydroglucose repeating unit in the cellulose skeleton with substitution. Therefore, the degree of substitution can be a maximum of 3 for cationic cellulosic polymer. Reduced compactness in the same way as has been found, reduces enzymatic degradation. The compactness of the cationic cellulosic polymer is heterogeneously substituted cationic cellulose polymer. For example, cationic hydroxyethyl or hydroxypropylcellulose, how Cam�Lena heterogeneity, are hydroxyethylene and/or hydroxyproline groups along the cellulose skeleton. Believe that the increased compactness increases the number of consecutive unsubstituted anhydroglucose repeating units available to attack cellulose enzyme. A measure of this heterogeneity is the ratio of unsubstituted trimers (U3R): the ratio of unsubstituted anhydroglucose trimmers and most often substituted anhydroglucose trimers. U3R is calculated using the method of mass spectrometry as described in US 2006/0182703 A1 (page 4, paragraphs 48-56). For cationic hydroxyethyl and hydroxypropylcellulose, hydroxyethylene and/or hydroxyproline molar substitution is preferably from 1.3 to 5, and the ratio of unsubstituted anhydroglucose trimmers and most often substituted anhydroglucose of trimers is preferably less than 0,235, more preferably less than 0,21.
Resistance to disintegration under the action of cellulose enzyme can also be strengthened by increasing the substitution at the C2 position in anhydroglucose duplicate link. The distribution of the substituents at C2, C3 and C6 positions in anhydroglucose repeating the link for cationic cellulose polymers, such as cationic hydroxyethyl cellulose, cationic hydroxypropyl cellulose and their produ�nye, can be measured by the method of Lindberg described in Carbohydrate Research, 170 (1987) 207-214. These polymers contain eight types anhydroglucose repeating units, in terms of the number and location of substituents, abbreviated called SO, S2, S3, S6, S23, S26, S36 and S236. They are defined as S0 - unsubstituted anhydroglucose links; S2, S3, S6-anhydroglucose links with one substituent in the C2, C3 and C6, respectively; S23, S26, S36 - anhydroglucose links with two substituents numbered in the regulations; S236 - anhydroglucose links with all three of the replaced provisions. Since C3 relative to directionspoint, the measure increased substitution at the C2 position is given using the percentage of C2-substituted trimers (i.e. the sum of S2, S23, S26, S236) relative to the percentage of C6-substituted trimers (sum of S6, S26, S36, S236). To improve enzyme stability by using a favourable substitution in C2, with the percentage of C2-substituted trimers is preferably more than 0.8 times, more preferably more than 0.9 times, the percentage of C6-substituted trimers.
To further reduce any decay under the action of a cellulose enzyme, non-aqueous liquid composition may contain a cationic cellulosic polymer in the form of particles. That is, cationic cellulose�th polymer is insoluble in non-aqueous liquid composition, or not fully soluble in non-aqueous liquid composition. Acceptable forms include solid particles of a substance which completely do not contain water and/or another solvent, but also include solids that are partially hydrated and/or solvated. Partially hydrated or solvated particles are those which contain water and/or other solvent at levels that are insufficient to cause complete solubilization particles. A useful property of partial hydration and/or solvation of cationic cellulosic polymer is that in any form agglomerates have a low strength of the filter cake and is easily re-dispersed. Such hydrated or solvated particles in General contain from 0.5% to 50%, preferably from 1% to 20% of water or solvent. While water is preferred, any solvent capable of partial solvation of cationic cellulosic polymer, may be used. The particles of the cationic cellulosic polymer is preferably as small as possible. Acceptable particles have an average diameter square D90 less than 300 microns, preferably less than 200 microns, more preferably less than 150 microns. The average diameter of the square D90 is defined as 90% of the particles having a size less than the square cu�ha having a diameter D90. Method of measuring particle sizes are given in the section Test methods.
For beneficial effects the feel of fabrics and care of color, non-aqueous liquid composition may contain from 0,000005% to 0.2%, preferably from 0.00001 to 0.05%, more preferably from 0.0001% to 0.02% by weight of cellulose enzyme. However, cationic cellulose polymers, it has been found that disintegrate even at residual levels of cellulose enzyme in aqueous compositions. In fact, non-aqueous liquid composition according to the present invention, as has been found to provide a useful effect on the levels of cellulose enzyme, at least 0,0000046% by weight. Even at such a low level of cellulose enzyme, it has been found that decomposes cationic cellulose polymers in aqueous compositions.

The product standard dose
Non-aqueous liquid composition according to the present invention can accommodate products in standard doses containing at least one fluid-filled compartment. The fluid-filled compartment relates to the separation of the product standard dose containing a liquid capable of wetting the fabric, like clothing. These products are standard dose contain in one, easy to use dosage form: cationic cellulose polymer and cellulose enzyme contained in the nonaqueous compositions encapsulated in a water soluble or dispersible film.
The product standard doses may be of any type, FD�we and material, that was acceptable to hold the non-aqueous compositions, i.e. not allowing the release of non-aqueous composition, and any additional component, from the product of the standard dose before contact products standard dose of water. The exact execution will depend on such factors as the type and number of tracks in the product standard dose and number of offices in the product standard doses, and the characteristics required of a product standard doses are kept, protect and deliver or release the compositions or components.
The product standard dose contains water-soluble or water-dispersible film, which completely covers the at least one internal volume containing a non-aqueous composition. The product standard doses may not necessarily contain extra compartments containing non-aqueous liquid and/or solid components. Alternatively, any additional solid component can be suspended in a fluid-filled compartment. Standard dosage form with multiple compartments may be desirable for reasons such as: the separation of chemically incompatible ingredients; or if it is desirable that the proportion of ingredients was released in the wash sooner or later.
It may be preferable to any branch that contains the liquid component, also �won air bubble. Air bubble may have a volume less than 50%, preferably less than 40%, more preferably less than 30%, more preferably less than 20%, most preferably less than 10% of the amount of space specified office. Without being bound by theory, believe that the presence of the air bubble increases the portability of the product standard dose to the movement of the liquid component within the compartment, thereby reducing the risk of leakage of the liquid component from the separation.
Water-soluble or water-dispersible film
Water-soluble or water-dispersible film typically has a solubility of at least 50%, preferably at least 75%, more preferably at least 95%. Method of determining the water solubility of the film is given in the Test methods section. Water-soluble or water-dispersible film typically has a time for dissolution in less than 100 seconds, preferably less than 85 seconds, more preferably less than 75 seconds, most preferably less than 60 seconds. The method of determination of time of dissolution of the film, see Test methods.
The preferred films are polymeric materials, preferably polymers which are formed into film or sheet. The film can be obtained by casting, blow molding, extrusion or extrusion with subsequent rasuwa� polymeric material, as is known in the art. Preferably, water-soluble or dispersible film comprises: polymers, copolymers or their derivatives, including polyvinyl alcohols (PVA), polyvinylpyrrolidone, polyalkylene, acrylamide, acrylic acid, cellulose, ethers of cellulose, esters of cellulose, cellulose amides, polyvinyl acetate, polycarboxylic acids and salts, polyaminoamide or peptides, polyamides, polyacrylamide, copolymers of maleic/ acrylic acids, polysaccharides including starch and gelatine, natural gums such as xanthan gum and gum gum karaya, and mixtures thereof. More preferably, water-soluble or dispersible film comprises: polyacrylates and water-soluble acrylate copolymers, methylcellulose, carboxymethylcellulose, dextrin, ethylcellulose, hydroxyethyl cellulose, hydroxypropyl methylcellulose, maltodextrin, polymethacrylates, and mixtures thereof. Most preferably, water-soluble or dispersible film comprises: polyvinyl alcohols, copolymers of polyvinyl alcohol, hydroxypropyl methylcellulose (HPMC), and mixtures thereof. Preferably, the level of polymer or copolymer in the film is at least 60% by weight. The polymer or copolymer preferably has a weighted average molecular weight of from 1000 to 1000000, more preferably from 10000 to 300000, d�more preferably from 15,000 to 200,000 and most preferably from 20,000 to 150,000.
Can also be used copolymers and mixtures of polymers. This can be in particular useful for the control of mechanical properties and/or dissolution properties of the compartments or the products are standard dose, depending on their application and specific needs. For example, it may be preferred that the mixture of polymers is present in the film, if one polymer material has a higher solubility than another polymer material, and/or one polymer material has a higher mechanical strength than another polymer material. The use of copolymers and mixtures of polymers can have other benefits, including improving the long term sustainability of water-soluble or water-dispersible film to detergent ingredients. For example, US 6,787,512 reveals copolymer film of polyvinyl alcohol containing a hydrolyzed copolymer of vinyl acetate and a second monomer sulfonic acid, for improved resistance to detergent ingredients. An example of such a film is sold by Monosol from Merrillville, Indiana, US, under the brand name: M. It may be preferable to use a mixture of polymers having different weighted average molecular weight, for example a mixture of polyvinyl alcohol or its copolymer with a weighted average molecular weight of from 10000 to 40000 and the other polyvinyl alcohol or a copolymer� with a weighted average molecular weight of from 100000 to 300000.
Also useful are polymer mixtures, for example containing hydrolytically degradable and water-soluble polymer blend such as polylactide and polyvinyl alcohol, obtained by mixing polylactide and polyvinyl alcohol, typically containing from 1 to 35% by weight polylactide and about 65% to 99% by weight of polyvinyl alcohol. The polymer in the film can be hydrolyzed from 60% to 98% , more preferably from 80% to 90%, to improve the dissolution/dispersion of the film material.
Water-soluble or water-dispersible film in this application may contain additional ingredients, in addition to the polymer or copolymer material. For example, it may be useful to add plasticizers, such as glycerol, ethylene glycol, diethylene glycol, propylene glycol, sorbitol and mixtures thereof; additional water and/or agents of decay.
Other suitable examples of commercially available water-soluble films include polyvinyl alcohol and partially hydrolyzed polyvinyl acetate, alginates, cellulose ethers such as carboxymethylcellulose and methylcellulose, polyethylene oxide, polyacrylates and combinations thereof. Most preferred are films with properties similar to the properties of the films containing polyvinyl alcohol known under the brand M, which is sold by Monosol, Merrilville, Indiana, US.
A method of producing and re-mixing
The preferred method of producing a non-aqueous compositions in accordance with the present invention includes a stage on which (i) provide a non-aqueous liquid raw material; (ii) combine the cationic cellulosic polymer with a non-aqueous liquid feedstock; and (iii) combine the cellulose enzyme is combined with a nonaqueous liquid raw material and a cationic cellulose polymer. Alternatively, the cellulose enzyme can be added before adding the cationic cellulose polymer. Preferably, a cationic cellulose polymer and/or cellulose enzyme can be added as part of a premix or as a dispersion of particles. If cationic cellulose polymer is added as part of a premix, or a dispersion of particles, premix or dispersion particles preferably contains from 1% to 35%, more preferably from 10% to 25% by weight of cationic polymer. Cellulose enzyme is preferably added as a premix in a premix with propandiol and/or water. Cellulose premix may contain from 5 mg/g to 50 mg/g, preferably from 10 mg/g to 20 mg/g of cationic cellulase.
Non-aqueous feedstock may contain some or all of the remaining ingredients, including anionic and/or nonionic surfactants. In another implementation of the method may include the step of forming the outside�it structure-forming premix and joins an outer structure forming the premix with a cationic cellulose polymer, or non-aqueous raw material, or the combined dispersion of a cationic cellulosic polymer /cellulase/ non-aqueous liquid raw material.
Non-aqueous liquid composition may be contained in the product standard doses. This product is a standard dose can be obtained in accordance with methods known in the art. For example, water-soluble or water-dispersible film is cut to a desired size, and then folded to form the necessary number and size of offices. Edge then hermetically sealed using any suitable technology, for example, thermal welding, wet seal or sealing under pressure. Preferably, the source of hermetic sealing are brought into contact with the specified tape, apply heat or pressure to the hermetic sealing of the film material.
Water-soluble or water-dispersible film, typically, is injected into a mold and applying a vacuum so that the film is flush with the inner surface of the mold, forming an indent or niche in the specified material film. This is called vacuum forming. Another acceptable method is thermoforming. Thermoforming typically includes a step of forming water-soluble or water-dispersible foams in the mold under the influence of heat, h�about allows the specified film to deform and take the shape of the mould.
Typically more than one piece of water-soluble or water-dispersible material film is used for the manufacture of the product standard doses. For example, the first chunk of the film material can be vacuum drawn into the mold so that the first piece of film material is flush with the inner walls of the mold. The second piece of the film material may be positioned such that it completely overlaps with the first piece of the film material. The first piece of the film material and the second piece of the film material hermetically sealed together. The first and second pieces of water-soluble or water-dispersible film may be made of the same material or may be different materials.
The method of obtaining the product of the standard dose with multiple compartments, a piece of water-soluble or water-dispersible material film is formed, at least twice, or, at least, three strips of film material is used, or at least two pieces of film material is used, where at least one piece of film material is folded at least once. The third piece of the film material, or a folded piece of material protectors, creates a barrier layer that, when the materials of the film are hermetically sealed together, divides the internal volume prod� standard dose into two or more branches.
The product standard doses with multiple compartments can also be obtained by fitting a first piece of film material into a mold. Composition, or its components, may then be poured into the mold. Pre-formed compartment can then be placed over the mold containing the composition, or component. Pre-formed Department also preferably comprises a composition or a component. Pre-formed Department and specified the first piece of water-soluble or water-dispersible material film are hermetically sealed together to form the product of the standard dose with multiple compartments.
The present invention also provides a method for re-mixing the non-aqueous liquid composition according to the present invention with the second non-aqueous composition, characterized in that the second non-aqueous composition comprises a polymer based on cellulose, preferably cationic cellulose polymer. Alternative polymer cellulose-based second non-aqueous composition may be an anionic cellulosic polymer, such as carboxymethyl cellulose and/or carboxymethyl cellulose, modified ester.
1) Measurement of pH:
the pH was measured in pure composition at 25°C using Santarius RT-10P pH meter with �spruce probe (e.g., the Toledo probe, part number 52 LLC 100), which is calibrated in accordance with the instructions.
2) Method of measuring particle size:
Occhio Flow Cell FC200-S (Angleur, Belgium) was used to measure the distribution of particle sizes. A sample containing particles for analysis, was diluted to 2% by weight, with PEG200 to ensure the detection of one particle. 2 ml of the diluted samples were analyzed in accordance with the instructions supplied with the device.
3) Method of measuring the solubility of water-soluble or water-dispersible films:
5.0 grams±0.1 gram of the water-soluble or water-dispersible film was added to a previously weighed beaker 400 ml and added 245 ml±1 ml of distilled water. The mixture was vigorously stirred on a magnetic stirrer set at 600 rpm, for 30 minutes. Then the mixture was filtered through a filter of sintered glass with a pore size of up to 20 microns. The water was dried from the collected filtrate by any traditional method, and the mass of the remaining material is determined (which was a dissolved or dispergirovannoyj fraction). You can calculate the solubility in percent or dispersibility.
4) Method of measuring time of the dissolution of water-soluble or water-dispersible films:
The film was cut out and mounted in a foldable frame slide for slide n�sister 24 mm by 36 mm, without glass (part number 94.000.07, Else comes, The Netherlands, however, there may be used plastic folding frame from other suppliers).
Standard glass beaker, 600 ml was filled with 500 ml of tap water at 10°C and stirred with a magnetic wand for stirring, so that at the bottom there was a vortex at a height of 400 ml graduations on the glass.
The frame of a diapositive secured by clamps to the vertical bracket and suspended in water, 36 mm horizontal side along the diameter of the Cup so that the edge of the frame of a diapositive 5 mm were given for the side of the glass, and the top of the frame of the slide was at an altitude of 400 ml graduations Stopwatch was started immediately after placing the frame of the slide in water, and stopped when the film was completely dissolved. This time, it was registered as "the time of dissolution of the film".
5) Method of assessment of beneficial effects of soft non-aqueous liquid compositions;
Characteristics of softness was evaluated using the following procedure:
