Compositions comprising a xyloglucan conjugate and processes for making and using such compositions.
Polysaccharide-conjugates can be used to deliver materials, such as benefit agents, to a situs. Generally, a benefit agent constitutes the aforementioned conjugate portion of a polysaccharide conjugate. Unfortunately, when such polysaccharide conjugates are employed in a cleaning or treatment context, they are incompatible with other cleaning and/or treatment ingredients, the deposition of such polysaccharide conjugates on the target situs is not as great as desired and, in many cases, the color of the situs is negatively impacted by such deposition. In addition, the use of such polysaccharide conjugates is not economical as the processes employed to produce such polysaccharide conjugates are not as efficient as desired and/or do not allow for all the desired conjugates to be linked to the polysaccharide. Thus, the use of this technology continues to be limited.
Surprisingly, when select xyloglucan conjugates are employed in cleaning and/or treatment compositions, the aforementioned problems are eliminated or greatly reduced.
This invention relates to compositions comprising a xyloglucan conjugate and processes for making and using such compositions.
As used herein, the term “cleaning and/or treatment composition” includes, unless otherwise indicated, granular or powder-form all-purpose or “heavy-duty” washing agents, especially laundry detergents; liquid, gel or paste-form all-purpose washing agents, especially the so-called heavy-duty liquid types; liquid fine-fabric detergents; fabric rejuvenation products designed to restore the appearance of faded fabrics; hand dishwashing agents or light duty dishwashing agents, especially those of the high-foaming type; machine dishwashing agents, including the various tablet, granular, liquid and rinse-aid types for household and institutional use; liquid cleaning and disinfecting agents, including antibacterial hand-wash types, laundry bars, mouthwashes, denture cleaners, car or carpet shampoos, bathroom cleaners; hair shampoos and hair-rinses; shower gels and foam baths and metal cleaners; as well as cleaning auxiliaries such as bleach additives and “stain-stick” or pre-treat types.
As used herein, the phrase “is independently selected from the group consisting of . . . ” means that moieties or elements that are selected from the referenced Markush group can be the same, can be different or any mixture of elements.
As used herein, the articles “a” and “an” when used in a claim, are understood to mean one or more of what is claimed or described.
As used herein, the terms “include”, “includes” and “including” are meant to be non-limiting.
Unless otherwise noted, all component or composition levels are in reference to the active level of that component or composition, and are exclusive of impurities, for example, residual solvents or by-products, which may be present in commercially available sources.
Unless otherwise noted, the enzymes of the present invention are expressed in terms of active protein level and are exclusive of impurities, for example, residual solvents or by-products, which may be present in commercially available sources.
All percentages and ratios are calculated by weight unless otherwise indicated. All percentages and ratios are calculated based on the total composition unless otherwise indicated.
It should be understood that every maximum numerical limitation given throughout this specification includes every lower numerical limitation, as if such lower numerical limitations were expressly written herein. Every minimum numerical limitation given throughout this specification will include every higher numerical limitation, as if such higher numerical limitations were expressly written herein. Every numerical range given throughout this specification will include every narrower numerical range that falls within such broader numerical range, as if such narrower numerical ranges were all expressly written herein.
Suitable xyloglucan conjugates include xyloglucan conjugates that are conjugated at their reducing end with a benefit agent. Suitable non-limiting examples of xyloglucan conjugates may be represented by one of the structures below, based on a ring-opened terminal glucose moiety at the reducing end of a xyloglucan oligosaccharide and/or polysaccharide:
wherein,
Wherein Ar is an aryl or naphthyl ring, which may be further substituted. Alk is an aliphatic group which may be further substituted.
R1, R2, R3, and R4 represent covalently bonded benefit group(s).
Suitable xyloglucan conjugates can be produced in accordance with the teachings of USPA 2004/0091977 A1 and USPA 2006/0242770 A1, and H. Brumer et al., Journal of the American Chemical Society, 2004, volume 126, p. 5715-5721.
In one aspect, in addition to reducing end conjugation, the xyloglucan oligosaccharides or polysaccharides are conjugated at their beta-1,4-linked glucan backbone or side chains.
In one aspect, side chain conjugation can be accomplished by treatment of xyloglucan with galactose oxidase, which oxidizes galactose side chain residues to aldehydes which can then be reacted with amine-containing benefit groups to produce an imine-linked covalent conjugate.
In one aspect, vicinal diol functionality present throughout the xyloglucan backbone and side chains can be derivatised by treatment with cyanogen bromide which leads to a cyclic imidocarbonate or cyanate ester intermediate which can be reacted with amine-containing benefit groups to produce a covalent conjugate linked through an isourea, N-substituted imidocarbonate, or N-substituted carbamate.
In one aspect, primary hydroxyl groups present on unsubstituted glucose residues in the backbone and in side chain residues can be acylated using lipase as a catalyst and further derivatised in accordance with M. T. Gustavsson et al., Biomacromolecules, 2005, volume 6, pp 196-203.
In one aspect, any of the xyloglucan conjugates disclosed in the present specification can be processed into particulates. Without being bound by theory, it is believed that such particulates have enhanced stability and/or solubility. In one aspect, said particulates may be encapsulates. The encapsulating material typically encapsulates at least part, and normally all, of the xyloglucan conjugate. Typically, the encapsulating material is water-soluble and/or water-dispersible. The encapsulating material may be a microsphere made from plastic such as thermoplastics, acrylonitrile, methacrylonitiile, polyacrylonitrile, polymethacrylonitrile and mixtures thereof; commercially available microspheres that can be used are those supplied by Expancel of Stockviksverken, Sweden under the trademark Expancel®, and those supplied by PQ Corp. of Valley Forge, Pa. USA under the product codes PM 6545, PM 6550, PM 7220, PM 7228, and tradenames Extendospheres®, Luxsil®, Q-cel® and Sphericel®.
In one aspect, said particulates may be “noodles”, used to refer to generally cylindrical particles prepared by extruding a paste through the holes of extruder die plate followed by processing the extrudates into pieces of desirable length.
In one aspect, said particulates may be spray dried granules, produced by spray drying the xyloglucan conjugate with other materials to produce particulates with the desired properties.
In one aspect, said particulates may be agglomerates produced by granulating the xyloglucan conjugate with other materials to produce particulates with the desired properties.
Partially purified xyloglucan polysaccharide is available from Dainippon Pharmaceuticals, Osaka, Japan under the tradename Glyoid® S such material is generally suitable for use as a raw material for the synthesis of xyloglucan conjugates. Where further purification is desired, such purification can be accomplished by dispersing the starting material in cold deionised water, while stirring for 12 hours so as to obtain a homogeneous dispersion. In order to separate, by precipitation, any possible proteins present, the dispersion so obtained is heated for 30 minutes at 80° C., and, after cooling, is subjected to centrifugation for 30 minutes at 5000 r.p.m. The supernatant solution is then dialysed against water for at least 48 hours at 4° C., using 12,000-14,000 daltons cut-off membranes. The resulting solution is finally lyophilised, giving a translucid, white final product that is typically totally soluble in water. The absence of contaminating proteins can be verified by polyacrylamide gel electrophoresis with sodium dodecyl sulphate (SDS-PAGE).
Xyloglucan has a backbone composed of 1,4-linked β-D-Glcp residues. Up to 75% of these residues are substituted at O6 with mono-, di-, or triglycosyl side chains. A single letter nomenclature is used to simplify the naming of xyloglucan side chain structures. For example, a capital G represents a unbranched Glcp residue. A capital F represents a Glcp residue that is substituted with a fucose-containing trisaccharide. The nomenclature is shown below:
Xyloglucans may be classified as XXXG-type of XXGG-type. XXXG have three consecutive backbone residues that are substituted with Xylp and a fourth unbranched backbone residue. XXGG xyloglucans have two consecutive branched backbone residues and two unbranched backbone residues.
The xyloglucan conjugates of the present invention and compositions comprising same can deliver a diversity of desired benefits to fabrics including, but not limited to, improved fabric odor, stain removal, soil release, soil repellency, cleaning, whitening, dyeing, tinting, resistance to dye fading, softening, improved hand, resistance to pilling, resistance to wrinkling, ease of ironing, transfer of materials to human skin, resistance to abrasion, retention of fabric shape, improved fabric tensile strength, protection from microbial buildup, protection from attack by fungi or insects and/or reduced skin irritation.
Suitable conjugated benefit groups, denoted as R, may be linked to the ring-opened xyloglucan oligosaccharide or polysaccharide, either directly, for example through an amide or ester bond, or through a linker group. A linker group may be useful when it is desired to join chemical entities which might not otherwise interact, for example due to lack of chemical reactivity, some other form of chemical incompatibility or steric hindrance. A linker group may also be useful when it is desired to conjugate a single xyloglucan oligosaccharide reducing end with more than one benefit group.
Prior to linking the benefit group R with the xyloglucan, the benefit group R typically contains a moiety selected from the group consisting of amine, alcohol, aldehyde, ketone, carboxylic acid, sulfonic acid, thiol, acyl halide, alkene, nitro compound, diazonium ion, alkyl halide, alkyl toluenesulfonate and mixtures there of. Typically, the benefit group R and the xyloglucan are linked (conjugated) via a linker group including, but are not limited to, amide, azo compound, carbonate, disulfide, ether, ester, hydroperoxide, imine, imide, nitrate, phosphodiester, phosphate, sulfide, sulfone, ketone, urethane, thioester, triazine and/or sulfonamide functional groups.
In one aspect of the invention, the benefit group is linked to the xyloglucan oligosaccharide or polysaccharide through a bond which may be subsequently hydrolysed during the washing or drying stages of the wash process. In one aspect, such hydrolysis may be catalysed by a hydrolase enzyme including, but not limited to, a lipase, esterase, cutinase, amidase and mixtures there of.
Suitable conjugated benefit groups R include, but are not limited to, perfumes, perfume particles, enzymes, fluorescent brighteners, oil repellent agents, water repellent agents, soil release agents, soil repellent agents, dyes including fabric renewing dyes, hueing dyes, dye intermediates, dye fixatives, lubricants, fabric softeners, photofading inhibitors, antiwrinkle/ironing agents, shape retention agents, UV absorbers, sunscreens, antioxidants, crease resistant agents, antimicrobial agents, skin benefit agents, anti-fungal agents, insect repellents, photobleaches, photoinitiators, sensates, enzyme inhibitors, bleach catalysts, odor neutralizing agents, pheromones and mixtures there of.
