Description

WO 2009/047126 PCT/EP2008/062874 LAUNDRY DETERGENT WITH PRETREATMENT ADDITIVE AND ITS USE This invention relates to granular laundry detergent 5 compositions containing pre-treatment additives for intensive treatment of fabric during washing and to a process for use of the composition during hand washing of laundry. 10 BACKGROUND It is known to include visually contrasting particles in granular laundry detergent compositions. The particles may 15 deliver a functional ingredient and/or provide a visual cue. In US 4082682, a minor proportion of contrastingly colored elongated soap particles is added to a detergent powder. The particles comprise a non substantive dye and fluorescer. 20 The powder comprises a detergency builder compound. The soap particles contribute detergency to the composition and reduce foaming. Because the soap particles could sink onto the fabric it is a stated advantage of the particles that they do not cause staining of the fabric with which they 25 come into contact. In order to improve the visibility and weight effectiveness of a visual cue it is proposed in GB2358403A to form the contrasting particle from a film, for example, a coloured 30 water-soluble polymer film. Such particles are of significantly larger average particle size in at least one WO 2009/047126 PCT/EP2008/062874 -2 dimension than the average particle size of the powder particles. The examples disclose 5 mm diameter circular or star shaped colored polymer film particles dry mixed into a built detergent powder comprising sodium linear alkylbenzene 5 sulphonate anionic surfactant. In W02006/079416, it is disclosed that the polymer film particles used in GB2358403A may be unsuitable for use in some detergent powder applications, due to poor solubility. 10 W02006/079416 proposes a film based visual cue of high solubility. It is suggested to be possible to include functional ingredients within the film e.g. surface active agents, perfume, antioxidant, antifoam. The visual cues are preferably formed of gum Arabic and have a triangular or 15 "spiky" appearance. US4176079 describes a detergent powder composition comprising a water soluble polymer film. An enzyme is incorporated into a film, which is then cut into squares, 20 rectangles or strips and added to detergent powder. Typical film compositions are polyvinyl alcohol 48.7% and nonionic surfactant 43.8% (balance water and enzyme). The cut functional film pieces have a surface area of approx 300 mm2 per side. No dye or other additive is added to the film to 25 make it stand out from the detergent powder. The film may be plasticised and aerated. Particularly for laundry hand wash compositions there are several problems. 30 WO 2009/047126 PCT/EP2008/062874 -3 One problem is the pre-treatment of fabrics. Often stains are difficult to remove during a standard wash and the consumer needs to pre-treat stains by application of a composition to the localised area of the stain. This either 5 requires purchasing several products, which is expensive and a hassle for the consumer, or the consumer uses more powder, which is wasteful. Another problem is to make a cue that adds functionality, so 10 that its weight effectiveness is improved, especially when added to water. Another problem is the effectiveness of visual cues in reinforcing and conveying perfume attributes to the user. 15 Another problem is to make a visual cue that persists long enough to give the desired indication to the user and yet dissolves well enough not to be a concern to the user, especially at low temperatures and under hand wash 20 conditions. DEFINITIONS Visual Cue 25 Means a consumer perceivable point of differentiation in a detergent composition. This could be a feature of the bulk composition: e.g. colour, viscosity, size of granules, or it could be achieved by having visually distinct particles 30 included in the composition, in a minor amount.

WO 2009/047126 PCT/EP2008/062874 -4 Visual Cue Particle Means a coloured speckle, film particle or other solid visually contrasting particle added to a detergent 5 composition in a minor amount to function as a visual cue. Lamellar Visual Cue (or Lamellae) Means visual cue particles in the form of planar film 10 material made into shapes. The shapes may be cut from a sheet of film or may be cast directly. Such lamellae are also called "film particles". Flower Shaped (or Flower-Like) 15 Means planar film shapes (or lamellae) that have the outline of the shape of a flower with petals. Especially a stereotypical flower having a central generally circular area with a number, preferably six, of rotationally 20 symmetrically dispersed "petals" radiating therefrom. SUMMARY OF THE INVENTION 25 According to the present invention there is provided a granular laundry detergent composition comprising surfactant and 0.1 to 10 wt% soluble coloured lamellar visual cues made from a soluble film, wherein the visual cues have a cross sectional area of from 5mm2 to 100mm2, characterised in that 30 the film comprises 10 to 90 wt% surfactant to enable pre treatment of fabric and that the film has a relative density C \NRPonbi DCC EJB \34050451DOC -5 of 0.2 to 0.8 which ensures that the visual cues float on water. Advantageously the cross-sectional area of the visual cues enables them to be scooped into a human hand. The inclusion of surfactant in the visual cue provides cleaning functionality. The low relative density and colour further provides a functional visual cue, which is clearly visible during the early stages of a hand wash due to its size and colour, and the fact that it floats. These attributes, allow the consumer to pick up at least one visual cue from the surface of the washing solution and rub it onto a fabric stain to pre-treat the stained area. With standard speckles, this is physically impossible as they are too small and they sink. Thus, according to a second aspect of the invention there is provided a method of using the composition comprising adding it to water and scooping at least one visual cue off the surface of the water and then rubbing it over an area of fabric that requires pre treatment, for example a stained area. According to another aspect the present invention provides a granular laundry detergent composition comprising 0.1 to 10 wt% soluble coloured lamellar visual cues made from a soluble film, each soluble coloured lamellar visual cue having a planar cross-sectional area of from 5mm 2 to 100 mm2 the relative density of the film being from 0.2 to 0.8 kg/1 and the film comprising 10 to 90 wt% surfactant, water soluble polymer and non-fabric-substantive colorant.

CANRPortbl DCOE713\34050451 DOC -5A DETAILED DESCRIPTION OF THE INVENTION The detergent formulation 5 The visual cues may be added to a major proportion of visually contrasting granular laundry detergent composition. The precise content of the granular laundry detergent composition is not critical for putting the invention into practice. The only restriction is that the granular WO 2009/047126 PCT/EP2008/062874 -6 composition must not unduly affect the ability of the visual cues to separate out to form a separate highly visible floating portion, when the detergent composition is added to water. 5 The granular laundry detergent composition may be built or unbuilt, low or high foaming, and contain any suitable type of detersive surfactant. However, it is preferred for handwash applications that they are built high foaming 10 compositions comprising anionic surfactant. Phosphate and/or carbonate builders are preferred. It is especially beneficial if the surfactant system in the powder has synergistic compatibility with the anionic surfactant in the visual cue. Such surfactant combinations are well known in 15 the field. The granular composition may be manufactured by any of the known processes, such as spray drying, dry mixing and combinations thereof. It may be formed by using adjunct 20 granules. It is desirable that the visual cues are post dosed to the composition, preferably using a low shear mixer to ensure an even distribution of the visual cues through the granular composition. The film particles are included in the total composition at a weight percentage in the range 25 0.01 to 10 wt%, preferably 0.03 to 2 wt% most preferably 0.1 to 1 wt%. The compositions may suitably contain from 10 to 80%, preferably from 15 to 70% by weight, of detergency builder. 30 Preferably, the quantity of builder is in the range of from 15 to 50% by weight.

WO 2009/047126 PCT/EP2008/062874 -7 Often granular detergents used for hand washing of laundry include inorganic phosphates, more especially sodium tripolyphosphate. Other possible phosphate builders are sodium orthophosphate and pyrophosphate. 5 Sodium tripolyphosphate is preferably present in an amount of from 10 to 40 wt%, more preferably from 15 to 35 wt%, most preferably from 20 to 30 wt%. 10 Alternative inorganic builders that may be used in place of or in addition to phosphates are sodium carbonate, layered silicates, amorphous aluminosilicates. Alternatively or additionally, the detergent compositions of 15 the invention may contain as builder a crystalline alkali metal (preferably sodium) aluminosilicate (zeolite). Preferred zeolites are zeolite A (zeolite 4A), and zeolite MAP as described and claimed in EP 384 070B. 20 Organic builders that may be used include polycarboxylate polymers such as polyacrylates and acrylic/maleic copolymers; polyaspartates; monomeric polycarboxylates such as citrates, gluconates, oxydisuccinates, glycerol mono-, di- and trisuccinates, carboxymethyloxysuccinates, 25 carboxymethyloxymalonates, dipicolinates, hydroxyethyl iminodiacetates, alkyl and alkenyl malonates and succinates; and sulphonated fatty acid salts. Especially preferred organic builders are citrates, suitably 30 used in amounts of from 5 to 30 wt %, preferably from 10 to 25 wt %; and acrylic polymers, more especially WO 2009/047126 PCT/EP2008/062874 -8 acrylic/maleic copolymers, suitably used in amounts of from 0.5 to 15 wt %, preferably from 1 to 10 wt %. Builders, both inorganic and organic, are preferably present in alkali metal salt, especially sodium salt, form. 5 Other ingredients that are beneficially contained within a granular detergent composition include any that are conventionally employed in such compositions. Especially preferred are ingredients conventionally used in hand 10 washing compositions. Thus, sodium sulphate, enzymes, fluorescers, dye transfer inhibiters, anti redeposition agents, shading dye and enzymes are desirably included. Although it is possible to include bleach, this is less preferred for hand wash compositions. 15 Use of a green granule in the composition is advantageous if used with film colours that are associated with flowers. The visual cue effect due to this floral colour selection is further amplified by the green "stem" colour contrast in the 20 granular composition. This is especially important for use with perfumes evocative of nature, such as floral perfumes. The Film particle 25 a) Composition of the visual cues The visual cues are made of coloured film. The essential components of the film are polymer, surfactant and a non fabric-substantive colorant. Optional further ingredients 30 are: adjuncts to assist in the manufacture of the film, for instance release agents, other functional ingredients, and WO 2009/047126 PCT/EP2008/062874 -9 water. Besides its effect of control of relative humidity of the film, water also assists in plasticising the film and regulates its solubility. 5 The polymer may be selected from water soluble film forming polymers, especially those used in formulation of detergent powders. Preferred polymers include polymers which dissolve and/disperse completely in water within 30 minutes with agitation at a temperature anywhere in the range of from 20 10 to 600C. Preferred water soluble polymers are those capable of being cast into a film or solid mass, for example as described in Davidson and Sittig, Water-Soluble Resins, Van Nostrand 15 Reinhold Company, New York (1968). Preferred water-soluble resins include polyvinyl alcohol, cellulose ethers, polyethylene oxide, starch, polyvinylpyrrolidone, polyacrylamide, polyvinyl methyl ether-maleic anhydride, polymaleic anhydride, styrene maleic anhydride, 20 hydroxyethylcellulose, hydroxypropylmethylcellulose, polyethylene glycols, carboxymethylcellulose, polyacrylic acid salts, alginates, acrylamide copolymers, guar gum, casein, ethylene-maleic anhydride resin series, polyethyleneimine, ethyl hydroxyethylcellulose, ethyl 25 methylcellulose, hydroxyethyl methylcellulose, sugars. Lower molecular weight water-soluble, polyvinyl alcohol film forming resins are preferred. Polyvinyl alcohols preferred for use therein have an average 30 molecular weight anywhere between 1,000 and 1,000,000, preferably between 5,000 and 250,000, for example between WO 2009/047126 PCT/EP2008/062874 - 10 15,000 and 150,000. Hydrolysis, or alcoholysis, is defined as the percent completion of the reaction where acetate groups on the resin are substituted with hydroxyl, -OH, groups, A hydrolysis range of from 60-99% of polyvinyl 5 alcohol film-forming resin is preferred, while a more preferred range of hydrolysis is from about 70-90% for water-soluble, polyvinyl alcohol film-forming resins. The most preferred range of hydrolysis is 80-89%. As used in this application, the term "polyvinyl alcohol" includes 10 polyvinyl acetate compounds with levels of hydroloysis disclosed herein. Another suitable polymer is a polyvinyl alcohol film, made of a polyvinyl alcohol copolymer having a comonomer having a 15 carboxylate function. The preferred grade of PVA picks up water only at an RH well above that of granular detergent compositions. Thereby, it protects the other film ingredients from decomposition by 20 water and soluble dyes from bleeding. Fluorescer can be included in the film to increase the effect of the visual cue. A low level of suitably coloured dye may also be included to counter any yellowing. Shading dye and Aloe Vera may be included in the film too. 25 The visual cue film particle may comprise 10 to 80% polymer or polymer mixture. The cue must contain surfactant to remove stubborn stains. 30 In particular, the visual cue needs to have a minimum of 10 % surfactant, but preferably > 20 %. Although any suitable WO 2009/047126 PCT/EP2008/062874 - 11 surfactant or surfactant system, may be used. The surfactant is preferably an anionic surfactant, especially if the granular composition comprises a builder. At least 10 wt% anionic surfactant is preferably included in the 5 film. Suitable anionic surfactants include are well-known to those skilled in the art. Examples of high-foaming sulphonate or sulphate type surfactants include alkylbenzene sulphonates, 10 particularly linear alkylbenzene sulphonates having an alkyl chain length of C-C15; primary and secondary alkylsulphates, particularly C8-C15 primary alkyl sulphates; olefin sulphonates; alkyl xylene sulphonates; dialkyl sulphosuccinates; and fatty acid ester sulphonates. Sodium 15 salts are generally preferred. Further information is given in the open literature, for example, in "Surface-Active Agents and Detergents", Volumes I and II, by Schwartz, Perry and Berch. 20 The preferred anionic surfactants are alkylbenzene sulphonates, more especially linear alkylbenzene sulphonate (LAS), which is preferably present in an amount of from 12 to 24 wt%, more preferably from 12 to 22 wt% and especially 25 from 15 to 22 wt%. Even more preferred are primary alcohol sulphates (PAS), particularly C8-Ci8, preferably C12-C15, primary alcohol sulphates. A particularly preferred surfactant is primary 30 alcohol sulphate (PAS) with a carbon chain length of 12.

WO 2009/047126 PCT/EP2008/062874 - 12 Visual cue Film particles containing up to 50 % PAS, may be used. The film may additionally include a second surfactant. The 5 second surfactant is preferably chosen from amphoteric surfactants, zwitterionic surfactants, nonionic surfactants and ethoxylated anionic surfactants. Preferred amphoteric second surfactants are amine oxides. 10 The most preferred amine oxide is coco dimethylamine oxide. Preferred zwitterionic second surfactants are betaines, and especially amidobetaines, for example, coco amidopropyl betaine. 15 Preferred nonionic second surfactants include the primary and secondary alcohol ethoxylates, especially the C8-C20 aliphatic alcohols ethoxylated with an average of from 1 to 20 moles of ethylene oxide per mole of alcohol, and more 20 especially the C1o-C15 primary and secondary aliphatic alcohols ethoxylated with an average of from 1 to 10 moles of ethylene oxide per mole of alcohol. Preferred ethoxylated anionic second surfactants, include 25 alkyl ether sulphates (ethoxylated alcohol sulphates). Also suitable for use as second surfactants in the visual cues of the present invention are C8-Ci8 alkyl monoethanolamides, for example, coco monoethanolamide.

WO 2009/047126 PCT/EP2008/062874 - 13 The second surfactant system used in the film particle may additionally comprise minor amounts, e.g. less than 5% of the film, of cationic surfactant. 5 The surfactant, or surfactant system, fulfils two functions in the film. It enhances the solubility of the film and it provides detersive action to enable the film to be used directly on wetted stains. Surfactant may be included at a level of up to 90 wt%, preferably up to 75 wt%, most 10 preferably up to 60 wt% in the film. The visual cue needs to be easily visible in wash liquor as well as against the background of the detergent formulation, therefore it needs to be coloured. Non fabric-substantive 15 colorants are included in the film composition at a level of 0.05 to 0.5 wt%, preferably 0.1 to 0.3 wt%, most preferably 0.15 to 0.25 wt%. Suitable colorants include any that are used to colour 20 detergent liquids or powders. Yellow, blue, violet, lilac, purple, red, orange, green, pink are preferred colours. White may also be used if the remainder of the detergent composition is of sufficient contrast. However, white is not preferred because it does not have very high visibility 25 on the water surface. Preferably, the film is the same colour as detergent variant The "colour" of the variant is the predominant colour of the packaging and marketing material used to represent that 30 variant. However, it is also within the scope of the invention to have different coloured visual cue film WO 2009/047126 PCT/EP2008/062874 - 14 particles for different types of pre-treatment, all included in one composition in one pack. Once added to water one colour or a mix of coloured cues may easily be selected and scooped up for use either separately, or in combination. 5 Yellow cues did not have a high visual contrast from a white powder before film cues. Now, with the improved contrast due to the higher cross section area, they can be used as natural floral cues along with the preferred floral colours. 10 b) Size and shape of the visual cue film particles To achieve the required level of visibility to function as a visual cue in the composition and to be easily seen when 15 floating on the water surface the film particles need to be significantly bigger than the average detergent powder particles. The particle size of granules in the detergent composition typically ranges from 0.1 to 2 mm. The film particles are also advantageously a different shape from the 20 generally spherical granules in the detergent composition. The film particle size in two dimensions is preferably at least 3 mm, more preferably at least 4 mm. In the third dimension the film particle is the thickness of the film, which is at most 1mm, preferably 0.4 mm, more preferably 25 0.25mm, most preferably 0.2 mm thick. Being this flat shape also assists the film particles to float. 30 Each visual cue film particle has a cross sectional area of between 5 mm2 and 100 mm2. Preferably, the number of WO 2009/047126 PCT/EP2008/062874 - 15 particles that will be dosed to each wash lies in the range 20 to 200. The preferred cross-sectional area of a film particle is 10 to 30 mm2, preferably 15 to 20 mm2, whereby the size of the film particle enables it to be scooped 5 easily into a human hand from the wash liquor. It is preferred that if the composition is a built granular laundry detergent composition then the visual cues should have a maximum diameter at least twice that of the detergent granules. 10 The invention also provides a shaped visual cue, which does not segregate during mixing, handling, or transport, but which does segregate in use. Cues may be shaped into the form of petals, hexagons, squares, circles, stars. 15 Preferably, the visual cue is petal shaped and the petal is the same colour as detergent variant. To maximise the impact of the film particle as a visual cue 20 for perfume the film is cut into the shape of something natural and normally associated with a smell, e.g. petal, flower, floret etc. Ideally the shape and also, most ideally, the colour of the film particle is linked to the perfume. We have found that the size is less important to 25 cue for perfume than either shape or colour. In a modification of the shape of the film particle it is formed to resemble a petal with a central dot or hole to make it look more like a real flower. The latter further 30 reduces the weight too.

WO 2009/047126 PCT/EP2008/062874 - 16 The film may be used flat or it may be formed into a three dimensional shape, for example by making larger bubbles from two sheets of film laminated together around their edges, or in some other more complex configuration, like "bubble 5 wrap". Provided buoyancy is maintained, the cavities may be filled with other ingredients that assist in the pre treatment of fabrics. These may be liquids, pastes or solids. Such ingredients may additionally or alternatively be included into the film itself. 10 c) relative density of the film particles The film used should float on water. To achieve this for sufficient time while the visual cue dissolves we have found 15 that it should have a density of between 200 and 800 g/l, preferably between 230 and 500 g/l, most preferably 250 to 400 g/l. Surprisingly we have found that film particles of this density and having the preferred particle dimensions set forth above, do not unduly segregate from a detergent 20 powder during manufacture or during storage and transportation. This is advantageous because it means that the particles provide a uniform level of visibility on the surface of the pack during use and it also assists in ensuring that roughly the same number of particles are does 25 to the wash and thus ensures that the ability to pre-treat with the floating particles is not hindered by their separation in the pack. The low relative density ensures that the film particles 30 float on the surface of an aqueous wash liquor. This is achieved by a combination of the chemicals used and the WO 2009/047126 PCT/EP2008/062874 - 17 degree of aeration applied to the film during its manufacture. The bubbles of air also diffuse light, which has the effect of enhancing visibility and distinctiveness of the film, especially when it is floating on the water 5 surface. The bubbles are also thought to improve the dissolution of the film. The film may be made of low density by inclusion of porosity in the manufacturing stage. This can be by means of large 10 light diffusing bubbles of gas beaten in to the mixture during film making or it can be achieved by gas evolved from film ingredients (e.g. citric acid and carbonate). The bubbles can be nano-bubbles. Film with capillaries may also be used. Also films with ribs that form open capillaries 15 and meshes or films with active and lightweight ingredients in its "pores". Method of use of the detergent composition with pre-treater 20 The composition is added to water. This can be done before or after the clothes. Immediately, the pre-treatment film particles float and appear to separate from the remainder of the composition. The consumer is reassured to see that the brightly coloured particles are not coming into direct 25 contact with the clothes (although no harm would be done if they did). The film particles slowly dissolve on the surface over a period of 5 minutes to 30 minutes. The powder or liquid dissolves in the water faster and delivers builder to the water; if it is a built composition. 30 WO 2009/047126 PCT/EP2008/062874 - 18 If pre-treatment is needed, the consumer may scoop film particles off the water surface using their hand and use these particles to pretreat fabric. Between 3 and 10 particles may easily be scooped up at once, depending on the 5 level of treatment desired. Thus, the consumer is in control of the dosage of surfactant to be used for pre treatment. Furthermore, use of the cue in this way, in conjunction with 10 a wash liquor, to provide building or some other enhancement of the detergency of the cue gives improved detergency relative to use of the cues on their own. A further advantage of the visual cue floating is that it 15 avoids the problems of variable speed of dispersion and/or dissolution that can occur if the particle gets embedded in clothing at the bottom of the wash liquor. This is a particular problem for hand washing processes. 20 A yet further advantage of the visual cue floating during the early stages of the wash is that the film particles are highly visible to the consumer. This means that they effectively continue to communicate the benefit of improved fragrance or other benefit for which they are designed to 25 cue. For instance, by selecting cues in the shape and colour of small florets it has been shown that the consumer perceives a floral perfume more hedonistically and expresses clear preference for a formulation containing the perfume and the cues over one without cues or with a cue that does 30 not look so much like a floret (i.e. a hexagonal cue of equivalent area). For communicating perfume or fabric care WO 2009/047126 PCT/EP2008/062874 - 19 benefits during the wash cues that float are also preferred by potential consumers over cues that sink. 5 Examples Under static conditions shapes need to dissolve not faster than 10 minutes and not slower than 30 minutes, preferably between 15 and 25 minutes. 10 Pre-treatment A white carbonate built granular laundry detergent formulation comprising a floral perfume and primary alcohol sulphate as the main surfactant was combined with 0.5 wt% yellow film cues comprising 47wt% polyvinylalcohol, 48wt% 15 primary alcohol sulphate, non substantive yellow colorant and water. The relative density of the film was approx 0.3. The yellow film was just under 0.2 mm thick on average and had been cut into floret shapes with a maximum diameter of approximately 5 mm in the other two dimensions. 20 A standard dosage of the composition including the visual cues was added to water at 35 0C and immediately the visual cue florets floated and dispersed over the surface of the water in the washing vessel and contributed to a perception 25 of a pleasant floral perfume given off by the wash liquor. A handful of florets were easily scooped up using the fingers as a sort of strainer and the wet florets were rubbed with finger ends over a piece of cotton cloth stained with tomato oil. The stain was easily removed in a few 30 seconds. As a control experiment, at the same time an identical stain was wetted with the wash liquor and rubbed -20 by a finger end and the stain was still visible for some time longer than the pre-treatment with the visual cue florets containing anionic surfactant. 5 Throughout this specification and the claims which follow, unless the context requires otherwise, the word "comprise", and variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of 10 any other integer or step or group of integers or steps.
