BLEACHING COMPOSITIONS

Abstract: The present invention relates to bleaching compositions comprising a hypohalite bleach, a borate or boric acid or a mixture thereof and a tertiary alcohol and/or a polyalcohol. These bleaching compositions exhibit excellent fabric yellowing-prevention performance and/or fabric safety.

Description: BLEACHING COMPOSITIONS Field of the invention The present invention relates to bleaching compositions, which can be used to bleach various surfaces including but not limited to fabrics, clothes, carpets and the like as well as hard-surfaces like walls, tiles, floors, glass, bathrooms surfaces, kitchen surfaces, toilet bowls and dishes. Background of the invention Bleach-containing compositions for bleaching various surfaces, e.g., fabrics, are well known in the art. Amongst the different bleaching compositions available, those relying on bleaching by hypohalite bleach, such as hypochlorite, are often preferred, mainly for bleaching performance reasons. However, a drawback associated with the use of hypohalite bleach-containing compositions, e.g., hypochlorite-based compositions, is that said compositions may potentially damage and/or cause yellowing of the fabrics being bleached. During the bleaching operation, a liquid hypochlorite-containing composition for example, can be applied onto the fabric in neat or diluted form. The hypochlorite bleach can be present in various forms, including hypochlorous acid and in the form of various molecule fragments resulting from its decomposition pathways. Hypochlorous acid and these molecule fragments are reactive with fabrics and may cause damage and/or yellowing of fabrics being bleached. Therefore, bleaching compositions are often formulated comprising bleach and a fabric protective system. Compositions comprising bleach and one of various fabric protective systems are well known in the art. An example is a bleaching composition based on hypohalite bleach comprising a polymer and a borate as a fabric protective system (EP-A-0 824 147), or bleaching compositions based on hypochlorite comprising a metaborate as a fabric protective system (EP-A-0 781 840). However, there are some limitations to the convenience of said bleaches comprising a fabric protective system. In particular, it is well known from consumer research that said compositions may still damage and/or yellow the fabrics which are being bleached, although said compositions comprise a fabric protective system. It is therefore an object of the present invention to provide a bleach-containing composition, suitable for use in laundry applications, whereby the fabric yellowing-prevention is further improved. It is a further object of the present invention to provide a bleaching composition, suitable for use in laundry application, whereby fabric safety is further improved. Fabrics made of cotton and/or synthetic materials have free hydroxyl groups. It is believed that fabric damage and/or fabric yellowing occurs due to the oxidation of the hydroxyl groups by the bleach. The oxidation of the hydroxyl groups is believed to be further emphasised at lower pHs. Indeed, low pH shifts the chemical equilibrium between hypochlorite and hypochlorous acid in favor of the latter. Hypochlorous acid is a more aggressive bleach, which has been found to further contribute to fabric yellowing and fabric damage. Moreover, it is further believed that the hydroxyl groups of the fabric are more easily oxidised at lower pHs. It has been found that fabric protection can be achieved using a combination of a borate and/or boric acid and a tertiary alcohol and/or a polyalcohol in bleach- containing compositions. The bleaching compositions of the present invention provide further improved fabric yellowing-prevention and/or further improved fabric safety on fabrics bleached therewith, as compared to bleaching compositions comprising other fabric protective systems, e.g., a metaborate alone, or bleaching compositions comprising no fabric protective system. It is believed that the hydroxyl groups of a fabric are protected by the fabric protective system as disclosed herein from oxidation by a bleach, especially a hypochlorite bleach, thus, providing fabric safety and/or fabric yellowing- prevention. Advantageously the bleaching compositions of the present invention are suitable for various laundry bleaching applications both when used in diluted conditions, e.g., as a detergent additive or a fully formulated laundry detergent composition, and when used in neat condition, e.g., as a liquid pretreater (spotter). A further advantage of the bleaching compositions according to the present invention is that they are able to perform in a variety of conditions, i.e., in hard and soft water as well as when used neat or diluted. Yet another advantage of the bleaching compositions of the present invention is that said bleaching compositions may also be suitable for the bleaching of different types of surfaces including hard-surfaces like floors, walls, tiles, glass, kitchen surfaces, bathrooms surfaces, toilet bowls and/or dishes and the like, as well as fabrics. More particularly, the bleaching compositions of the present invention are suitable for bleaching any type of fabrics including natural fabrics (e.g., fabrics made of cotton, viscose, linen, silk and wool), synthetic fabrics such as those made of polymeric fibers of synthetic origin as well as those made of both natural and synthetic fibers. Indeed, the bleaching compositions of the present invention may be used on synthetic fibers despite a standing prejudice against the use of hypohalite bleaches, especially hypochlorite bleaches, on synthetic fibers, as evidenced by warning on labels of commercially available hypochlorite bleaches and clothes. Background art Bleach-containing compositions based on hypohalite bleach suitable for bleaching surfaces, e.g., fabrics or hard-surfaces, have been described in the art. EP-A-781 840 discloses a composition comprising hypochlorite and a metaborate as a pH buffering means. However, compositions comprising a borate and/or boric acid and a tertiary alcohol as described herein are not disclosed. EP-A-0 824 147 discloses liquid bleaching compositions comprising a hypohalite bleach and a polymer. The composition may further comprise a boron salt as pH buffering component. However, compositions comprising a borate and/or boric acid and a tertiary alcohol as described herein are not disclosed. Summary of the invention The present invention encompasses a bleaching composition comprising a hypohalite bleach, a borate or boric acid or a mixture thereof, and a tertiary alcohol or a polyalcohol or a mixture thereof. The present invention also encompasses a process of bleaching surfaces, e.g., fabrics, wherein said surfaces are contacted with a bleaching composition as defined herein. The present invention further encompasses the use of a borate or boric acid or a mixture thereof and a tertiary alcohol or a polyalcohol or a mixture thereof, as a fabric protective system in a hypohalite bleach-containing composition to treat fabrics whereby a fabric yellowing-prevention benefit and/or good fabric safety benefit is provided. Detailed description of the invention The bleaching composition The bleaching compositions may be formulated either as solids or liquids. In the case where the bleaching compositions are formulated as solids, for example as granules, tablets or powders, they are preferably applied on the fabrics to be bleached according to the present invention in a liquid form, i.e., solid compositions are used in combination with an appropriate solvent, typically water. In the case where the bleaching compositions are formulated as liquids including gel and paste form, the bleaching compositions are preferably but not necessarily formulated as aqueous compositions. Liquid bleaching compositions are preferred herein for convenience of use. Preferred liquid bleaching compositions of the present invention are aqueous and therefore, preferably comprise water in an amount of from 60% to 98%, more preferably of from 80% to 97% and most preferably 85% to 97% by weight of the total composition. Hypohalite bleach As a first essential ingredient, the compositions of the present invention comprise a hypohalite bleach. Any hypohalite bleach known to those skilled in the art may be suitable for use herein. Suitable hypohalite bleaches may be provided by a variety of sources, including bleaches that lead to the formation of positive halide ions and/or hypohalite ions, as well as bleaches that are organic based sources of halides, such as chloroisocyanurates. Suitable hypohalite bleaches for use herein include the alkali metal and alkaline earth metal hypochlorites, hypobromites, hypoiodites, chlorinated trisodium phosphate dodecahydrates, potassium and sodium dichloroisocyanurates, potassium and sodium trichlorocyanurates, N-chloroimides, N-chloroamides, N- chloroamines and chlorohydantoins. For the bleaching compositions herein, the preferred hypohalite bleaches among those described above are the alkali metal or alkaline earth metal hypochlorites selected from the group consisting of sodium, potassium, magnesium, lithium and calcium hypochlorites, and mixtures thereof. Sodium hypochlorite is the most preferred hypohalite bleach. Accordingly, the bleaching compositions according to the present invention may typically comprise from 0.01% to 20%, preferably from 0.25% to 15%, more preferably from 0.1 % to 10%, even more preferably 0.5% to 8% and most preferably from 1% to 6% by weight of the total composition of a hypohalite bleach. Borate or boric acid As a second essential ingredient, the bleaching compositions according to the present invention comprise a borate or boric acid or a mixture thereof. Suitable borates include alkali metal salts of borates and mixtures thereof. Suitable alkali metal salts of borates include alkali metal salts of metaborate, tetraborate, octoborate, pentaborate, dodecaborate, borontrifluoride and alkyl borates containing from 1 to 12, preferably from 1 to 4 carbon atoms. Preferred alkyl borate includes methyl borate, ethyl borate and propyl borate. Particularly preferred herein are the alkali metal salts of metaborate, such as sodium metaborate, potassium metaborate, or mixtures thereof. Borates like sodium metaborate and sodium tetraborate are commercially available from Borax and Societa Chimica Larderello under the name sodium metaborate and Borax®. The borates provide a prolonged through-the-bleach buffering action, i.e., maintain the pH of the bleaching solution at a pH of at least 8, preferably at least 8.5, more preferably at least 9.5 for a longer period of time, throughout the bleaching process, e.g., at a dilution level of 200:1 (watercomposition), as compared to the buffering action obtained with the same composition without said borate. It has been found that the buffering action of the borate also affects the hypochlorite/ hypochlorous acid such that the shift of hypochlorite into hypochlorous acid is reduced. It is believed that by controlling this equilibrium, fabric damage and/or fabric yellowing can be reduced. The bleaching compositions according to the present invention may comprise from 0.01% to 10%, preferably from 0.1% to 10%, more preferably from 0.5% to 5%, even more preferably from 0.7% to 3%, and most preferably from 0.7% to 1.5% by weight of the total composition of said borate or boric acid or mixture thereof. Tertiary alcohol or polyalcohol As a third essential ingredient, the bleaching compositions according to the present invention comprise a tertiary alcohol or a polyalcohol or a mixture thereof. Suitable tertiary alcohols or polyalcohols are according to the following formula : OH OH OH Rι— - (CH 2 )n— (CCH_)m— (CH_)o — C — (CH^o"— (CCH 3 )m"— (CH^n"— R 3 (CH 2 )o' I (CCH 3 OH)m' I (CH^iY I R 2 wherein : R.,, R 2 and R 3 are independently linear or branched, saturated or unsaturated hydrocarbon chains of from 1 to 30, preferably from 1 to 20, more preferably from 1 to 10, even more preferably from 1 to 7, carbon atoms optionally comprising one or more C5 to C7, preferably Cβ, aromatic or aliphatic ring structures; and m, m', m" n, n', n", o, o' and o" are independently integers of from 0 to 1000, preferably 0 to 100, more preferably 0 to 50. Examples of suitable tertiary alcohols include tert-butyl alcohol, tert-amyl alcohol, 2-methyl 2-butanol and 2-methyl 2-pentanol. A particularly preferred tertiary alcohol is 2-methyl 2-butanol. An example of a suitable polyalcohol is 2,4-dimethyl butane-2,4-diol. Suitable tertiary alcohols and polyalcohols are commercially available from Aid rich. The bleaching composition according to the present invention may comprise from 0.001% to 20%, preferably from 0.001% to 5%, more preferably from 0.01% to 1%, and most preferably from 0.025% to 0.5% by weight of the total composition of a tertiary alcohol or a polyalcohol or mixture thereof as described herein. In a preferred embodiment according to the present invention the molar ratio of borate or boric acid or a mixture thereof to tertiary alcohol or polyalcohol or a mixture thereof is from 1 :1 to 30:1, more preferably from 1 :1 to 25:1 , more preferably from 2:1 to 25:1 , and most preferably of 20:1. Cotton fabrics contain cellulose (i.e., (CβHioOδJn)- When a bleach-containing composition, e.g., a hypochlorite-containing composition, is used to bleach a cotton fabric, the bleach may react with the hydroxyl substituents of cellulose in position 6, 2, 3 and 5 of the cellulosic ring and thus may introduce new functional groups like carbonylic, aldehydic and/or carboxylic groups. Synthetic fabrics may be made of various synthetic materials like polyamide-elasthane that also comprises hydroxyl groups capable of being oxidized by bleach. The applicant believes that it is these new functional groups that cause fabric damage and/or yellowing. It has now been found that a combination of a borate and/or boric acid and a tertiary alcohol and/or a polyalcohol as described herein, in the bleaching compositions according to the present invention act together as a fabric protective system. Compared to a bleach-containing composition comprising a fabric protective system other than that described by the present invention or no fabric protective system at all, the fabric yellowing-prevention performance and/or the fabric safety performance is further improved. Whilst not wishing to be bound by theory, it is believed that the fabric protective system consisting of a borate and/or boric acid and of a tertiary alcohol and/or a polyalcohol as described herein, in a bleaching composition according to the present invention is capable of protecting, e.g., esterifying and/or complexing the hydroxyl groups present on the fibers of a treated fabric. The fabric yellowing-prevention and/or fabric safety benefit can be achieved when using the compositions of the present invention neat, e.g., as a pretreater, as well as diluted, e.g., typical dilution with water in conventional washing conditions. Indeed, the yellowing-prevention effect and/or safety effect of the present invention can be evaluated by comparing the composition according to the present invention to a bleach-containing composition comprising a fabric protective system other than that claimed by the present invention. By "further improved fabric yellowing-prevention", it is meant herein that the yellowing of fabrics, i.e., the appearance of a yellowish tone of said fabrics, that occurs by using the hypohalite bleach-containing compositions of the present invention (e.g., those containing a hypochlorite bleach) is reduced ("fabric yellowing-prevention benefit"), compared to the yellowing that occurs by using a hypohalite bleach-containing composition comprising a fabric protective system other than that described by the present invention. The degree of yellowing can be determined by both visual and instrumental grading. Visually, the difference in yellowing between items treated with different compositions can be determined by a team of expert panelists. Instrumentally, the assessment can be determined with the help of Colorimeters such as Ganz Griesser® instruments (e.g., Datacolor® Spectraflash® SF 500, Machbet White- eye® 500) or a ZEISS ELREPHO® or others which are available for instance from Hunterlab® or Gardner®. By "further improved fabric safety", it is meant herein that the damage caused on fabric by using the hypohalite bleach-containing compositions of the present invention (e.g., those containing a hypochlorite bleach) is reduced ("fabric safety benefit"), compared to the damage caused by using a bleach-containing composition comprising a fabric protective system other than that described by the present invention. Fabric safety may be evaluated by different test methods including the degree of polymerisation test method according to UNI (Ente Nazionale Italiano di Unificazione) official method UNI 8282-Determinazione della viscosita intrinseca in soluzione di cuprietilendiammina (CED). Another aspect of the present invention is the use of a combination of a borate and/or boric acid and a tertiary alcohol and/or a polyalcohol, in a fabric bleaching composition comprising a hypohalite bleach to provide a fabric yellowing- prevention benefit and/or a fabric safety benefit of the bleaching composition. Bϋ The preferred pH range of the bleaching composition is from 8 to 14, preferably from 8.5 to 14, more preferably from 9 to 13.5, and even more preferably from 9.5 to 13.5. It is in this alkaline pH range that the optimum stability and performance of the hypohalite bleach, e.g., hypochlorite, is obtained. The compositions of the present invention may comprise an alkalinity source to adjust the pH of the compositions according to the present invention. Preferred bleaching compositions herein may comprise up to 10%, preferably of from 0.04% to 5% and more preferably of from 0.1% to 2% by weight of the total composition of said alkalinity source.

The most commonly available form of this phosphate is where M is Sodium. Phytic acid, which is a chelating agent particularly suitable for use herein, is a hexa-phosphoric acid that occurs naturally in the seeds of many cereal grains, generally in the form of the insoluble calcium-magnesium salt. It may also be derived from corn steep liquor. Commercial grade phytic acid is commercially available from J.T.Baker Co., e.g., as a 40% aqueous solution. It is intended that the present invention covers the acidic form of phytic acid as well as alkali metal salt derivatives thereof, particularly sodium or potassium salts thereof. Sodium phytate is available from Jonas Chemical Co (Brooklyn, N.Y.). In fact since the typical pH of the bleaching compositions of the present invention are in the alkaline pH range, the phytic acid component exists primarily as the ionized salt in the liquid compositions herein even if it is added in its acidic form. Mixtures of such salts of phytic acid are also covered. Polyfunctionally-substituted aromatic chelating agents may also be useful in the bleaching compositions herein.

Another example of such a brightener is bis(sulfobenzofuranyl)biphenyl, commercially available from Ciba-Geigy under the trade name Tinopal PLC®. Typically the bleaching compositions according to the present invention may comprise up to 1.0%, preferably from 0.005% to 0.5%, more preferably from 0.005% to 0.3% and most preferably from 0.008% to 0.1% by weight of the total composition of a brightener. Process of treating surfaces: In the present invention, the bleaching composition of the present invention is used by applying the composition to the surface to be treated. The compositions according to the present invention are preferably used in liquid form. By "in liquid form" it is meant that liquid compositions can be used per se in neat or in diluted form, and solid compositions, for example granules, tablets or powders, are dissolved in an appropriate solvent, typically water, before use, i.e., before being contacted to said surface. By "in diluted form", it is meant herein that the compositions for the bleaching of fabrics according to the present invention may be diluted with a solvent by the user, the preferred solvent is water. Such dilution may occur for instance in hand laundry applications as well as by other means such as in a washing machine. Said compositions can be used at a dilution level of up to 500:1 (solventcomposition), preferably from 5:1 to 200:1 and more preferably from 10:1 to 80:1 (solventcomposition). By "in its neat form", it is to be understood that the liquid compositions are applied directly onto the fabrics to be treated without undergoing any dilution, i.e., the liquid compositions herein are applied onto the fabrics as described herein. By "surfaces", it is meant herein any inanimate surface. These inanimate surfaces include, but are not limited to, hard-surfaces typically found in houses like kitchens, bathrooms, or in car interiors, e.g., tiles, walls, floors, chrome, glass, smooth vinyl, any plastic, plastified wood, table top, sinks, cooker tops, dishes, sanitary fittings such as sinks, showers, shower curtains, wash basins, WCs and the like, as well as fabrics including clothes, curtains, drapes, bed linens, bath linens, table cloths, sleeping bags, tents, upholstered furniture and the like, and carpets. Inanimate surfaces also include household appliances including, but not limited to, refrigerators, freezers, washing machines, automatic dryers, ovens, microwave ovens, dishwashers and so on. By "treating a surface", it is meant herein bleaching and/or disinfecting said surfaces as the compositions of the present invention comprise a bleach. Thus, the present invention also encompasses a process of treating (e.g., bleaching) a fabric, as the inanimate surface. In such a process a composition according to the present invention is contacted with the fabrics to be treated. This can be done either in a so-called "pretreatment mode", where a liquid bleaching composition, as defined herein, is applied neat onto said fabrics before the fabrics are rinsed, or washed then rinsed, or in a "soaking mode" where a bleaching composition, as defined herein, is first diluted in an aqueous bath and the fabrics are immersed and soaked in the bath, before they are rinsed, or in a "through the wash mode", where a bleaching composition, as defined herein, is added on top of a wash liquor formed by dissolution or dispersion of a typical laundry detergent. It is also essential in both cases, that the fabrics be rinsed after they have been contacted with said composition, before said composition has completely dried off. The compositions according to the present invention are preferably used on fabrics in a liquid form. More specifically, the process of bleaching fabrics according to the present invention comprises the steps of first contacting said fabrics with a bleaching composition according to the present invention, in its diluted form, then allowing said fabrics to remain in contact with said composition, for a period of time sufficient to bleach said fabrics, typically 1 to 60 minutes, preferably 5 to 30 minutes, then rinsing said fabrics with water. If said fabrics are to be washed, i.e., with a conventional composition comprising at least one surface active agent, said washing may be conducted by contacting said fabrics at the same time with a bleaching composition according to the present invention and said detergent composition, or said washing may be conducted before or after said fabrics have been bleached. Accordingly, said process allows the bleaching of fabrics and optionally the washing of fabrics with a detergent composition comprising at least one surface active agent before the step of contacting said fabrics with said bleaching composition and/or in the step where said fabrics are contacted with said bleaching composition and/or after the step where said fabrics are contacted with the bleaching composition and before the rinsing step and/or after the rinsing step. In another embodiment of the present invention the process of bleaching fabrics comprises the step of contacting fabrics with a liquid bleaching composition according to the present invention, in its neat form, of allowing said fabrics to remain in contact with said bleaching composition for a period of time sufficient to bleach said fabrics, typically 5 seconds to 30 minutes, preferably 1 minute to 10 minutes and then rinsing said fabrics with water. If said fabrics are to be washed, i.e., with a conventional composition comprising at least one surface active agent, said washing may be conducted before or after that said fabrics have been bleached. In an embodiment of the present invention wherein the liquid bleaching composition of the present invention, is contacted to the fabrics in its neat form, it is preferred that the level of hypohalite bleach, is from 0.01% to 5%, preferably from 0.1% to 3.5%, more preferably from 0.2% to 2% and most preferably from 0.2% to 1%. Advantageously, the present invention provides liquid hypohalite bleach-containing compositions that may be applied neat onto a fabric to bleach, despite a standing prejudice against using hypochlorite- containing compositions neat on fabrics. It is preferred to perform the bleaching process herein before said fabrics are washed. Indeed, it has been observed that bleaching said fabrics with the compositions according to the present invention (diluted and/or neat bleaching processes) prior to washing them with a detergent composition provides superior whiteness and stain removal with less energy and detergent than if said fabrics are washed first, then bleached. Alternatively instead of following the neat bleaching process as described above (pretreatment application) with a rinsing step and/or a conventional washing step with a liquid or powder conventional detergent, the bleaching pre-treatment operation may also be followed by the diluted bleaching process as described above either in bucket (hand operation) or in a washing machine. In another embodiment the present invention also encompasses a process of treating a hard-surface, as the inanimate surface. In such a process a composition, as defined herein, is contacted with the hard-surfaces to be treated. The process of treating a hard-surface with a composition, as defined herein, comprises the step of applying said composition to said hard-surface, and optionally rinsing said hard-surface. In the process of treating hard-surfaces according to the present invention the composition, as defined herein, may be applied to the surface to be treated in its neat form or may be applied at a dilution level of up to 200:1 (solventcomposition), preferably from 2:1 to 80:1 and more preferably from 2:1 to 60:1 (solventcomposition), preferably using water as the solvent. When used as hard-surfaces bleaching/disinfecting compositions the compositions of the present invention are easy to rinse and provide good shine characteristics on the treated surfaces.
