C4356 FORM - 2 THE PATENTS ACT, 1970 (39 of 1970) & The Patents Rules, 2006 COMPLETE SPECIFICATION (See Section 10 and Rule 13) FABRIC CONDITIONING KIT HINDUSTAN LEVER LIMITED, a company incorporated under the Indian Companies Act, 1913 and having its registered office at Hindustan Lever House, 165/166, Backbay Reclamation, Mumbai -400 020, Maharashtra, India The following specification particularly describes the invention and the manner in which it is to be performed WO 2005/063959 PCT/EP2004/013556 Fabric Conditioning Kit Field of the Invention 5 The present invention relates to a kit for rinsing fabrics, a rinse conditioning system, a method of preparing a dispersion and the use of a permeable article to prepare a dispersion. 10 Background of the Invention and. Prior Art Fabric conditioning compositions for use in the laundry are typically added to the laundry process after the washing stage. Where the laundry process involves an automatic 15 washing machine, the conditioning composition may need to be dosed either directly into the drum or via a dispensing tray. For hand-wash processes, the composition will be dosed into the hand-wash liquor. 20 Independent of the type of process, the fabric conditioning composition must firstly be sufficiently dispersed into the rinse liquor so that it can act on the fabrics being laundered. 25 If the composition is inadequately dispersed, there is a significant risk that it will not be deposited evenly on the fabric but will instead deposit at excessive concentrations on small portions thereof which in turn may lead to spotting or staining. There is also the risk that the ingredients 30 within the composition may not deposit at all and will WO 2005/063959 PCT/EP2004/013556 - 2 - instead remain in an undispersed state within the rinse liquor. This is clearly undesirable to consumers. 5 Dispersion of the composition may often not be fully complete before the composition is contacted with the fabrics to be treated. In the dispensing drawer of an automatic washing machine, this can manifest itself as a 10 build up of a gel-like residue requiring the consumer to carry out additional undesirable cleaning of the drawer. Dispersion thus remains problematic for fabric conditioning compositions. 15 Various ways of addressing this problem have been found including placing a dosed amount of the fabric conditioning composition into a container, adding water and shaking or mixing to form a pre-dispersion which can then be added to 20 the laundry cycle so as to disperse therein more easily. The drawback with this approach is that the consumer is burdoned with additional undesirable tasks and will typically be required to prepare such a pre-dispersion in advance of the laundry cycle. 25 It is thus remains desirable to provide a means for dispersing fabric conditioning compositions. Articles such as sponges are known for use with personal 30 washing products. WO 2005/063959 PCT/EP2004/013556 - 3 - A scrubbing apparatus used for personal hygiene, commonly referred to as a polymer mesh puff, is often used in cleansing the skin. These polymer mesh puffs are typically manufactured from one or more pieces of synthetic open cell 5 mesh which are bound together and manipulated into a plurality of random folds to form a generally rounded shape, or puff.

US 4,606,964 is directed to a bulked web composite which comprises a differentially tensioned reticulated web of 10 elastic material banded to at least one gatherable web. US 2,581,779 discloses a scouring pad said to have a greater ease of manipulation. 15 US 3,103,031 discloses a composite scouring pad made by folding plastic fibres with metallic filaments into an open batt. US 2,817,865 discloses a sponge covered strand washcloth 20 with soap pocket. The strands cross and are interwoven. US 5,144,744 discloses a hand-held ball-like polymeric mesh sponge. It is a diamond-mesh polyethylene sponge obtained from a number of netting tubes stretched over supports, 25 joined and bound together at the centre and then released from the supports. US 3,343,196 discloses a method for manufacturing a puff from an open cell mesh. 30 WO 2005/063959 PCT/EP2004/013556 - 5 - US 4,190,550 is directed to a fibrous soap filled pad which when used as a bathing aid imparts a cleansing and mildly stimulating rubbing action to human skin. 5 US 4,969,225 is directed to improved scrub brushes specifically made to contain a bar of soap for use for bathing, cleansing and the like. Commercially available "polymeric mesh sponges" are sold by 10 The Body Shop and Bynum Concepts, Inc. Other suppliers include Supremia Use in New Jersey, Sponge Factory Dominicana in the Dominican Republic and Integrated Marketing Group in Harrison, New York. 15 Typically, in the prior art, washing implements as described above find their greatest utility in combination with a liquid cleanser, since there is a need with liquid cleansers for the consumers to have an implement to grasp and with which to generate lather. 20 Often, the liquid cleanser includes a moisturising ingredient in addition to a surfactant. The desire for an implement to generate lather in a washing system including a moisturising cleansing composition is often foremost within 25 the contemplation of a consumer. Such a desire is mentioned in, for instance, WO 95/00116. By contrast, it has been long established that, for rinse conditioning products such as fabric softening compositions, 30 foaming is considered undesirable by consumers since foaming WO 2005/063959 PCT/EP2004/013556 - 6 - is associated only with a washing rather than a rinse conditioning step. Thus it is important to avoid foaming of the rinse 5 conditioning composition. Objects of the Invention The present invention seeks, to address one or more of the 10 abovementioned problems and/or to provide one or more of the abovementioned benefits. Surprisingly, it has now been found that a permeable, preferably porous article provides an excellent dispersing 15 means for fabric conditioning compositions. Statement of Invention Thus, according to the present invention there is provided a 20 system for conditioning fabrics comprising a fabric conditioning composition in combination with a permeable article for improving dispersion of the composition in a liquid. 25 The invention further provides a kit for conditioning fabric comprising a fabric conditioning composition in combination with a permeable article for improving dispersion of the composition in a liquid. 30 According to a further aspect, the invention provides a package comprising a permeable, preferably porous article, a WO 2005/063959 PCT7EP2004/013556 - 7 - fabric conditioning composition and instructions to disperse the composition in a liquid, preferably water, using the permeable article. 5 The invention also provides the use of a permeable, preferably porous article to disperse a fabric conditioning composition in a liquid, preferably water. According to yet another aspect, the invention provides a 10 method of dispersing a fabric conditioning ccrposition in a liquid, preferably water, by introducing the composition onto or into the permeable, preferably porous article, submersing the article in the liquid and agitating the article so as to assist dispersion of the co-position. 15 The invention still further provides a method of conditioning fabrics comprising dispersing a fabric conditioning composition in a liquid, preferably water, with the aid of a permeable, preferably porous article and then 20 contacting the dispersed composition with fabrics to be treated. Detailed Description of the Invention 25 In the context of the present invention, the term "comprising" denotes that the feature (s) to which it refers is/are not exhaustive and further features may be present Permeable Article 30 The system of the invention comprises a permeaoie article. WO 2005/063959 PCT/EP2004/013556 - 8 - Preferably the article is porous and/or absorbent. More preferably the article is a sponge or meshed article. 5 It is preferred that the article is compressible and it is particularly preferred that the article is resilient. Although the invention works with permeable/porous articles which have little or no compressibility and/or resilience, 10 it has been found that better dispersion can be achieved when the article is particularly compressible and/or flexible. It is believed that this is due to the article having 15 greater freedom of relative movement between different parts and/or surfaces of the article enabling a greater shearing action to occur within the article and thus better dispersion to be achieved. 20 The average diameter of the uncompressed article is typically from 2cm to 20cm, more preferably from 3cm to 15cm, most preferably from 4cm to 10cm. The article can be prepared from readily available raw 25 materials or with specially designed mesh materials. A suitable meshed article is preferably prepared from extruded tubular netting mesh which has been prepared from special strong and flexible polymeric material. Extruded 30 tubular netting mesh of this type, and particularly those WO 2005/063959 PCT/EP2004/013556 - 9 - prepared from polyethylene, have been used for the covering of meat and poultry and are readily available in industry. A polymeric meshed article preferably comprises a plurality 5 of plys of an extruded tubular netting mesh prepared from a strong flexible polymer, preferably of the group consisting of addition polymers of olefin monomers, and polyamides of polycarboxylic acids and polyamines. The plys of tubular netting mesh are typically folded upon itself numerous times 10 to form a soft ball-like polymeric mesh sponge. Alternatively, the mesh can be formed by binding a piece of tubular mesh or a sheet of mesh about a centre-point with a piece of string, and then forming a series of random folds 15 about this centre-point through various means of manipulation. In general the cross-sectional dimensions of each ply will be small in relation to the length of the ply. 20 The plys may be filaments. The ply may be elastomeric or non-elastomeric, but preferably the plys are elastomeric as this provides greater 25 freedom of movement of plys relative to each other. Preferably use of a large plurality of tiny plys offer substantial gripping surface area. Indeed, the user of the article will be enabled to thread his or her fingers through 30 the plys. While the use of plys that have a very small WO 2005/063959 PCT/EP2004/013556 - 10 - diameter as compared to ply length is envisioned primarily, the use of larger plys may also be advantageous. The article is preferably substantially spherical with a 5 plurality of floppy filaments radiating in a dense, bushy manner from a central core region. Generally, the plys will radiate outwardly in plural offset planes. The preferably open cell structure of the mesh 10 advantageously forms a structure which is highly resilient, resulting in a puff which retains its shape throughout use. In general, the diameter for the filaments will range from 0.25 to 3mm, preferably from 0.75 to 1.5mm. By "diameter" 15 in this context is meant the maximum width or thickness in the case of a ribbon-like structure or the like, or the true diameter in the case of a rod-like structure. In general, the length of the filaments is preferably from 1cm to 10cm, especially from 2 to 5cm for non-crimped filaments and from 20 2 to 15cm, especially from 5 to 12cm for crimped filaments (measured with the filament straightened). Although the preferred shape for the implement is spherical, other shapes such as a flattened oval, a football or a figure are contemplated. 25 The plys or filaments are preferably straight since this makes for a less "frilly" appearance, but they can also be curled or crimped. 30 Although the polymeric material of which the meshed article is made may be inherently mildly abrasive, it preferably WO 2005/063959 PCT/EP2004/013556 - 11 - does not incorporate abrasive particles or a scouring material. Thus, abrasives such as pumice, aluminium oxide, volcanic 5 ash, and silica are preferably omitted. Likewise, the meshed article should not be ammonia- or oxygen- releasing and preferably does not include bleaching materials. A suitable sponge is an open-cell sponge which possesses an 10 interconnected cell structure permitting limited absorption and circulation of gases and fluids. Outer surface of the material may be continuous or porous and exhibits good physical durability. Because air can pass freely between its cells, sponge offers a high degree of compressibility 15 and displays fast recovery upon release from compression. Examples of suitable sponges include both natural sponges such as sea sponges, e.g. silk, sea wool and yellow sponges and synthetic sponges, such as synthetic cellulosic sponges. 20 The system of the invention excludes "personal washing" compositions, that is compositions designed specifically for washing of the skin of human beings. 25 The system of the invention comprises the permeable article in combination with a fabric conditioning composition. WO 2005/063959 PCT/EP2004/013556 - 12 -Brief Description of the Drawings The permeable article for use in the invention will now be described by way of reference to the accompanying drawings 5 in which: Figure 1 shows a perspective view of a permeable, meshed article; 10 Figure 2 shows the meshed article of Figure 1 together with a rope; and Figure 3 shows netting material used in making the article of Fig's 1 and 2. 15 Detailed Description of the Drawings Referring to Figure 1 there is shown a representation of a polymeric hand held ball-like meshed article showing a rope 20 handle 7 used in the present invention. The ease with which a cleaning polymeric mesh sponge can be held in the hand for cleaning is shown in figure 2. A security band 13 holds the multi-layered netting mesh together to form the polymeric mesh sponge. The netting mesh that can be used in making 25 the polymeric mesh sponge is illustrated in figure 3 wherein 21 represents the mesh in stretched position. The fine polymeric filaments used in making the netting are represented by 18 with 19 representing the spot bonding of the filaments to form the open mesh 20. WO 2005/063959 PCTYEP2004/013556 - 13 - Two netting tubes at 60 cm length each can be used to make a 7cm ball sponge. They can be bundled manually with a loop or rope to form a ball-like polymeric mesh sponge. Other designs such as rectangular gloves and washings implements 5 made with the mesh material also work very well in the present invention system.

Mixtures of water and a low molecular weight, e.g. 30 lower alcohol such as ethanol, propanol, isopropanol or butanol are useful as the carrier liquid. Low molecular WO 2005/063959 PCT/EP2004/013556 - 28 - weight alcohols including monohydric, dihydric (glycol, etc.) trihydric (glycerol, etc.), and polyhydric (polyols) alcohols are also suitable carriers for use in the compositions of the present invention. 5 Polymeric viscosity control agents It is useful, though not essential, if the compositions comprise one or more polymeric viscosity control agents. 10 Suitable polymeric viscosity control agents include nonionic and cationic polymers, such as hydrophobically modified cellulose ethers (e.g. Natrosol Plus, ex Hercules), cationically modified starches (e.g. Softgel BDA and Softgel BD, both ex Avebe). A particularly preferred viscosity 15 control agent is a copolymer of methacrylate and cationic acrylamide available under the tradename Flosoft 200 (ex SNF Floerger) .' Nonionic and/or cationic polymers are preferably present in 20 an amount of 0.01 to 5wt%, more preferably 0.02 to 4wt%, based on the total weight of the composition. Antifoaming Agent 25 It is particularly preferred that the composition comprises an antifoaming agent. The antifoaming agent is preferably present at a level of from 0.001 to 5% by weight, more preferably 0.002 to 3% by 30 weight, most preferably 0.003 to 1% by weight, e.g. 0.004 to WO 2005/063959 PCT/EP2004/013556 - 29 - 0.7% by weight, based on the total weight of the composition. A typical antifoaming agent suitable for use in the 5 composition is DOW CORNING® 1520 Silicone antifoam (a 20% active silicone emulsion). Further Optional Ingredients 10 Other optional nonionic softeners, bactericides, soil-releases agents may also be incorporated in the compositions of the invention. The compositions may also contain one or more optional 15 ingredients conventionally included in fabric conditioning compositions such as pH buffering agents, perfume carriers, fluorescers, colourants, hydrotropes, antiredeposition agents, polyelectrolytes, enzymes, optical brightening agents, pearlescers, anti-shrinking agents, anti-wrinkle 20 agents, anti-spotting agents, antioxidants, sunscreens, anti-corrosion agents, drape imparting agents, dye fixatives, sequestrants, preservatives, anti-static agents, ironing aids and dyes. 25 Product Form The fabric conditioning composition may be a liquid, such as an aqueous liquid, preferably an aqueous dispersion of the cationic softening material, a soft solid such as a gel, 30 cream or paste, or a solid such as a granular material. Preferably the product is a liquid or soft solid. WO 2005/063959 PCT/EP2004/013556 - 30 - The invention is especially useful for very high viscosity compositions since these are often much harder to disperse than low viscosity compositions. In particular, it is 5 preferred that the composition has a viscosity as measured using a Haake Rotoviscometer with MV1 cup and Bob at 106s-l of greater than 200mPaS, more preferably greater than 400mPaS, most preferably greater than 500mPaS, e.g. greater than 600mPaS. Conventional liquid fabric conditioning 10 compositions have a viscosity of from 20-150mPaS. Product Use The composition is preferably used in a domestic laundry 15 operation such as an automatic washing machine, e.g. a top-loading washing machine, or a hand-washing laundry operation. It is particularly preferred that the present invention is used in a hand-washing operation where the fabrics are laundered by hand in a receptacle such as, for 20 example, a bucket, sink, bath or other suitably sized container. The system of the invention may, for instance, be sold in the form of a pack or kit. 25 The meshed article can thus be packaged together with a separate fabric conditioning composition such that none of the composition is impregnated or otherwise initially incorporated onto or into the implement. Of course, it is 30 envisaged that the fabric conditioning composition can be, in use, dosed either onto and/or into the meshed article and then placed in the wash/rinse liquor and dispersed or dosed WO 2005/063959 PCT/EP2004/013556 - 31 - directly into the wash/rinse liquor and then the meshed article is introduced into the liquor and used to disperse the composition or a combination of the above. 5 It is also envisaged that the kit may be supplied to the consumer with the permeable article pre-dosed with a fabric conditioning composition. Thus, at least initially, the consumer is not required to dose the permeable article with the fabric conditioning composition. 10 Examples The invention will now be illustrated by the following non-limiting examples. Further modifications will be apparent 15 to the person skilled in the art. Samples of the invention are represented by a number. Comparative samples are represented by a letter. 20 All values are % by weight of the active ingredient unless stated otherwise. The following fabric conditioning composition was prepared by melting together the quat, fatty acid, and lecithin, 25 adding this mixture to heated water, milling the mixture and then allowing it to cool. During cooling the citric acid, calcium chloride, perfume and minors were added.

A comparative product (sample A) was prepared by placing 15 3.5g/51 of the composition onto hands, submersing hands in 51 water and then rubbing together for 30 seconds. A dispersion according to the invention (sample B) was made using a meshed article by dispersing 3.5g/51 of the 20 composition onto and into the meshed article and then submersing the meshed article into 51 water and agitating the meshed article for 30 seconds. WO 2005/063959 PCT/EP2004/013556 - 33 - The dispersion was then visually assessed by a test panel of 4 people on a scale of 0 to 5 wherein 0 represents full dispersion and 5 represents extremely poor dispersion. 5 The results are given in the following table: Table 2 Panellist Sample A Sample B 1 3.5 0.5 2 5 1 3 4.5 0.5 4 4.5 0.5 C4356(C) COM 34 CLAIMS 1.
