WO 00/36072 PCT/US99/29330 1 5 BLEACHING COMPOSITIONS 10 15 Technical field 20 The present invention relates to a bleaching compositions which can be used to bleach various surfaces including but not limited to, hard-surfaces as well as fabrics, clothes, carpets and the like. 25 Background of the invention Commonly encountered liquid aqueous cleaning compositions for removal or 30 cleaning stains on fabrics and/or hard-surfaces may comprise a bleaching agent. A number of bleaching agents are known in the art. Halogen bleaches whilst being extremely effective bleaching agents, often also present a number of drawbacks which can sometimes dissuade a consumer from choosing the halogen-containing product. For example halogen bleaches, especially chlorine 35 bleaches, emit a pungent odour during and after use (e.g., on consumer hands and/or surfaces treated therewith) which some consumer find disagreeable.
WO 00/36072 PCT/US99/29330 2 Furthermore, it is known in the art that halogen bleach-containing compositions (typically hypochlorite) are relatively aggressive to fabrics and may cause damage when used in relatively high concentration and/or repeated usage. In 5 particular the consumer may perceive damage to the fabric itself (e.g. loss of tensile strength) or damage to the colour intensity of the fabric. While colour and fabric damage may be minimised by employing milder oxygen bleaches such as hydrogen peroxide or hydrogen peroxide generating bleaches, the bleach performance characteristics of such peroxygen bleaches are much less desirable 10 than those of the halogen-containing bleaching agents. Therefore, liquid aqueous activated peroxygen bleach-containing compositions have been developed containing activators, i.e., compounds which enhance peroxygen bleaching performance. However these bleaches do not perform as well as hypohalite bleaches in stain removal. 15 Peroxycarboxylic acid (peracid) bleaches are known in the art. The Applicant has found that such bleaches, in this instance, are particularly useful as they do not present the disadvantages of hypochlorite bleaches and are better performing bleaching agents than the oxygen bleaches. However generally peracid bleach 20 containing compositions have stability problems as the peracid prematurely begins to degrade. This premature degradation of the peracid is believed to be due to the presence of trace amounts of metal ions in the formulation which may catalyse the further degradation of the peracid. 25 The present invention thus provides a bleaching composition which is stable, safe to the surfaces treated and delivers improved bleaching performance when used in laundry applications and/or in any household application (e.g. bleaching/disinfecting of hard-surfaces). 30 Furthermore, it is believed that the solubility of the particulate pre-formed peracid is affected by the level of hardness ions. By 'hardness ions' it is meant ions that are present in water and form insoluble salts that precipitate from solution. The most predominant hardness ions are calcium and magnesium ions The water may be either water used to prepare the composition of the present invention or 35 may be the wash water into which the composition of the present invention is WO 00/36072 PCT/US99/29330 3 dispensed. Thus, it is another object of the present invention to prevent or at least reduce the precipitation of the peracid from the composition. The compositions according to the present invention may be useful in any 5 laundry application, e.g., as a laundry detergent or a laundry additive, and when used as a laundry pre-treater. A particular advantage of the compositions of the present invention is that they are suitable for the bleaching of different types of fabrics including natural fabrics, (e.g., fabrics made of cotton, and linen), synthetic fabrics such as those made of polymeric fibres of synthetic origin (e.g., 10 polyamide-elasthane) as well as those made of both natural and synthetic fibres. For example, the bleaching compositions of the present invention herein may be used on synthetic fabrics despite a standing prejudice against using bleaches on synthetic fabrics, as evidenced by warnings on labels of clothes and commercially available bleaching compositions like hypochlorite-containing 15 compositions. Another advantage of the bleaching compositions according to the present invention is that they can be used in a variety of conditions, i.e., in hard as well as soft water and in either neat or diluted form. More particularly, it has been 20 found that the liquid aqueous compositions of the present invention find a preferred application when used in their diluted form in any application and especially in any conventional laundry application. Indeed, upon dilution (typically at a dilution level of 20ml/L or more (composition:water)) the compositions of the present invention become less acidic, e.g., from a pH of about 1.5 to about 6.5 or 25 more. The compositions according to the present invention although delivering effective bleaching performance in their neat form surprisingly exhibit further enhanced bleaching performance in their diluted form. Actually, this "pH jump" effect allows to formulate acidic liquid aqueous compositions (i.e. pH below 7, preferably below 3 and more preferably below 2) which are physically and 30 chemically stable upon prolonged periods of storage and which deliver outstanding bleaching performance under diluted usage conditions. Yet another advantage of the compositions of the present invention is that they exhibit also effective stain removal performance on various stains including 35 enzymatic stains and/or greasy stains.
WO 00/36072 PCT/US99/29330 4 Summary of the invention 5 According to the present invention there is provided a liquid detergent composition comprising a pre-formed particulate peroxy carboxylic acid containing at least one aromatic group and a co-agent selected from the group consisting of organic acid, homo and copolymer of acidic monomers and mixtures thereof. In another preferred aspect of the present invention there is provided a liquid bleaching product comprising a first composition comprising a peroxy carboxylic acid containing at least one aromatic group and a second composition comprising a surfactant wherein the product is packaged such that first and second compositions are separated from each other. The present invention further encompasses methods of bleaching a surface with a composition according to the present invention. 10 Detailed description of the invention 15 Liquid bleaching composition The compositions according to the present invention are liquid and preferably aqueous. Thus the composition preferably has a water content of from 10% to 99%, more preferably from 30 to 95%, more preferably 40 to 90% by weight of 20 the composition. Where the composition according to the present invention is liquid is preferably has a pH of below 7. Preferably, the pH of the compositions according to the present invention is from 1 to 6, more preferably from 1 to 5, even more preferably from 2 to 4. Formulating the compositions according to the present 25 invention in the acidic pH range is critical to the chemical stability of the WO 00/36072 PCT/US99/29330 5 compositions according to the present invention. The pH of the composition is preferably below the pKa of the peracid used. It is believed that the acidic pH controls/limits the formation of highly reactive species which are unstable in acidic medium upon storage, and thus contributes to the stability of the 5 compositions for prolonged periods of storage. The pH of the compositions may be adjusted by any acid or alkaline species known to those skilled in the art. Examples of acidic species suitable for use herein are organic acids, such as citric acid and inorganic acids, such as sulphuric acid, sulphonic acid and/or metanesulphonic acid. Examples of 10 alkaline species are sodium hydroxide, potassium hydroxide and/or sodium carbonate. It has been found that the bleaching performance of the composition of the present invention is significantly improved versus the same composition but 15 without either the peroxycarboxylic acid and/or the co-agent. In fact it has been found that a synergy has been identified that could not have been foreseen from bleaching performance data of compositions comprising either the peroxycarboxylic acid or the co-agent alone. 20 The bleaching performance of the present composition may be evaluated by the following test methods on various type of bleachable stains. A suitable test method for evaluating the bleaching performance on a soiled fabric under diluted conditions is the following: A composition according to the 25 present invention is diluted with water typically at a dilution level of 1 to 100 ml/L, preferably 20 ml/L (composition :water), then the soiled fabrics are soaked in it for 20 minutes to 6 hours and then rinsed. Alternatively the bleaching composition can be used in a washing machine at a dilution level of typically at a dilution level of 1 to 100 ml/L (composition :water). In the washing machine the 30 soiled fabrics are washed at a temperature of from 300 to 70 0 C for 10 to 100 minutes and then rinsed. The reference composition in this comparative test undergoes the same treatment. Soiled fabrics/swatches with for example tea, coffee and the like may be commercially available from E.M.C. Co. Inc.. 35 The bleaching performance is then evaluated by comparing side by side the soiled fabrics treated with a composition of the present invention with those WO 00/36072 PCT/US99/29330 6 treated with the reference, e.g., the same composition but comprising no bleach or a different bleach. A visual grading may be used to assign difference in panel units (psu) in a range from 0 to 4. 5 An advantage of the compositions of the present invention is that they are physically and chemically stable upon prolonged periods of storage. Chemical stability of the compositions herein may be evaluated by measuring the concentration of available oxygen at given storage time after having 10 manufactured the compositions. By "chemically stable", it is meant herein that the compositions of the present invention comprising a peracid do not undergo more than 15% AvO loss, in one month at 250C and preferably not more than 10%. The loss of available oxygen (AvO) of a peracid-containing composition over time 15 can be measured by titration with potassium permanganate after reduction with a solution containing ammonium ferrous sulphate. This stability test method is well known in the art and is reported, for example, on the technical information sheet of CuroxR commercially available from Interox. Alternatively peracid concentration can also be measured using a chromatography method described 20 in the literature for peracids (F. Di Furia et al., Gas-liquid Chromatography Method for Determination of Peracids, Analyst, Vol 113, May 1988, p 793-795). By "physically stable", it is meant herein that no phase separation occurs in the compositions according to the present invention for a period of 7 days at 50'C. 25 Peroxy carboxylic acid The bleaching composition of the present invention comprises a pre-formed particulate peroxycarboxylic acid containing at least one aromatic group 30 (hereinafter referred to as peracid).

The fatty acids can also be synthetically prepared (e.g., by oxidation of petroleum stocks or by the Fischer Tropsch process). Alkali metal soaps can be made by direct saponification of fats and oils or by the 20 neutralization of the free fatty acids which are prepared in a separate manufacturing process. Particularly useful are the sodium and potassium salts of the mixtures of fatty acids derived from coconut oil and tallow, i.e., sodium and potassium tallow and coconut soaps. 25 The term "tallow" is used herein in connection with fatty acid mixtures which typically have an approximate carbon chain length distribution of 2.5% C14, 29% C16, 23% C18, 2% palmitoleic, 41.5% oleic and 3% linoleic (the first three fatty acids listed are saturated). Other mixtures with similar distribution, such as the fatty acids derived from various animal tallows and lard, are also included within 30 the term tallow. The tallow can also be hardened (i.e., hydrogenated) to convert part or all of the unsaturated fatty acid moieties to saturated fatty acid moieties.

WO 00/36072 PCT/US99/29330 30 Processes of treating surfaces In the present invention, the liquid aqueous composition of the present invention can be used to clean surfaces. By "surfaces", it is meant herein any inanimate 5 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 especially include fabrics including clothes, 10 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. 15 By "treating a surface", it is meant herein bleaching and/or disinfecting said surfaces as the compositions of the present invention comprise a bleaching system based on a peracid compound or a mixture thereof and optionally cleaning as said compositions may comprise a surfactant or any other 20 conventional cleaning agents. Thus, the present invention also encompasses a process of treating, especially bleaching a fabric, as the inanimate surface. In such a process a fabric is treated with a composition according to the present invention. Such treatment can be 25 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 with a conventional detergent, then rinsed, or in a "soaking mode" where a liquid bleaching composition, as defined herein, is first diluted in an aqueous bath and the fabrics are immersed and soaked in the bath, 30 before preferably being rinsed, or in a "through the wash mode", where a liquid bleaching composition, as defined herein, is added in to a typical laundry detergent. It is preferred in both cases, that the fabrics be rinsed after they have been contacted with said composition and before said composition has completely dried off. 35 WO 00/36072 PCT/US99/29330 31 The processes of bleaching surfaces according to the present invention, especially fabrics, delivers effective whiteness performance as well as effective stain removal performance. The compositions according to the present invention are preferably used to 5 contact to fabrics in a liquid form. Indeed, by "in a liquid form", it is meant herein the liquid compositions according to the present invention per se in neat or in their diluted form. The compositions according to the present invention are typically used in diluted form in a laundry operation. By "in diluted form", it is meant herein that the 10 compositions for the bleaching of fabrics according to the present invention may be diluted by the user, preferably with 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 diluted up to 500 times, preferably from 5 to 200 times and more preferably from 10 to 80 times. 15 More specifically, a 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 20 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 surfactant, said washing is preferably conducted together with the bleaching of said fabrics by contacting said fabrics at with a bleaching composition according to the present invention 25 and said conventional surfactant-containing detergent composition at the same time. In an alternative process said washing may be conducted before or after said fabrics have been bleached with a bleaching composition according to the present invention. Accordingly, said process according to the present invention allows the user to bleach fabrics and optionally to wash fabrics with a detergent 30 composition comprising at least one surfactant 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 said bleaching composition and before the rinsing step and/or after the rinsing step. 35 WO 00/36072 PCT/US99/29330 32 In a particularly preferred process of cleaning fabrics the bleaching composition and the surfactant containing conventional laundry detergent composition are applied to the fabric at the same time. Although it is essential that in this method the two compositions are not pre-mixed. 5 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. Thus, the present invention also encompasses a process of treating a hard surface with a composition, as defined herein, wherein said process comprises 10 the step of applying said composition to said hard-surface, preferably only soiled portions thereof, 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 in its diluted form typically up to 200 times their weight of water, 15 preferably into 80 to 2 times their weight of water, and more preferably 60 to 2 times. When used as hard surfaces bleaching/disinfecting compositions the compositions of the present invention are easy to rinse and provide good shine 20 characteristics on the treated surfaces. By "hard-surfaces", it is understood any hard-surfaces as mentioned herein before as well as dishes. 25 Packaqing form of the liquid compositions: Depending on the end-use envisioned, the compositions herein can be packaged in a variety of containers including conventional bottles, and bottles equipped with roll-on, sponge, brush or spray appliances. 30 In one particularly preferred embodiment of the present invention the composition is packaged in a two-compartment container, wherein the bleaching composition as described herein is packaged in one compartment and a second composition is packaged in the second compartment. In a particularly preferred aspect, the 35 second composition is a conventional laundry detergent liquid composition, WO 00/36072 PCT/US99/29330 33 preferably comprising ingredients, particularly bleach-sensitive ingredients such as surfactants, enzymes and perfumes.
WO 00/36072 PCT/US99/29330 34 Examples The invention is further illustrated by the following example which shows the stain removal benefits obtained by the combination of peracid bleach and citric acid. 5 The peracid used for the purposes of the present example is Phtaloylamido peroxycaproic acid (PAP), obtained from the supplier (Ausimont) as a 70% wet cake. The wetcake PAP is primarily dispersed in distilled water under gentle agitation using a lab stirrer, to form a dispersion containing 2.7g of pure PAP in 10 100 mls water. A 1% solution of citric acid is then prepared and the pH is trimmed to 4.0 with sodium hydroxide. The PAP dispersion and the citric acid solution are then mixed together to obtain a dispersion of PAP in the citric acid solutions. 15 The liquid detergent used was a commercial product marketed by the Procter & Gamble Company under the tradename Liquid Tide and was produced in summer 1998. It was used at 92 mls /wash (99 grams) as recommended. The compositions tested (in grams /wash) were: 20 - Liquid Tide (99g) - Liquid Tide (99g) + 1 g citric acid - Liquid Tide (99g) + 2.7 g PAP - Liquid Tide (99 g) + PAP/citric acid dispersion containing 1 g citric acid + 2.7 25 g PAP The PAP/citric acid dispersion was delivered into the washing machine at the same time as (but without premixing with) the liquid detergent. The tests were run using four identical Kenmore washing machines, using average US washing 30 conditions, at a wash temperature of 32 C, using 64 liters water, of a hardness of 1 millimole/liter. The wash pH was measured and was similar for all four treatments (between 7.6 and 7.9). In each wash a piece of fabric with a total of 20 stains, was introduced, together with 1.5 kg of a white ballast load of mixed (cotton/polycotton) composition. Four cycles were run by scrambling the 4 35 products across the 4 washing machines; for each cycle new stains were used. At the end, the results of the four wash cycles were averaged.
WO 00/36072 PCT/US99/29330 35 The fabrics are visually graded by two expert graders using the 0-4 Panel Score Unit (psu) scale, where 0 means no difference and 4 corresponds to the highest difference. All psu grades are referred to the Liquid Tide control and positive 5 grades mean a higher degree of stain removal vs Liquid Tide. The results were analyzed for statistical significance (at 95% confidence interval) and all grades that were significantly different vs. the Liquid Tide control are identified by the suffix "s". The results are shown here below: 1 2 3 4 Treatment: Tide Tide + Tide + PAP Tide + citric citric acid acid + PAP Stain removal Performance (psu) Stains: Wine 0.0 + 0.1 +0.5 + 1.1 s Coffee 0.0 + 0.1 +0.6 + 0.9 s Blueberry 0.0 + 0.2 +0.7 + 1.3 s Blackcurrant 0.0 + 0.5 +0.8 + 1.6 s Artificial 0.0 -0.2 + 0.7 s + 0.9 s menstrual fluid US Clay (on 0.0 + 0.4 -0.3 + 1.2 s Polyester) Average on all (20) 0.0 0.0 +0.3 + 0.7 s stains 10 The test shows that there is a synergy between PAP and citric acid, as the performance improvements of the PAP /citric acid combination is higher than the sum of the benefits obtained with citric acid alone and PAP alone. 15 The present formulations are provided to further exemplify the present invention, but are not intended to be limiting in any way.
