C4391 FORM - 2 THE PATENTS ACT, 1970 (39 of 1970) & The Patents Rules, 2003 COMPLETE SPECIFICATION (See Section 10 and Rule 13) FABRIC CONDITIONING COMPOSITIONS HINDUSTAN LEVER LIMITED, a company incorporated under the Indian Companies Act, 1913 and having its registered office at Hindustan Lever House, 1657166, 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 2006/013033 PCT/EP2005/008074 - 1 - FABRIC CONDITIONING COMPOSITIONS Field of the Invention 5 The present invention relates to fabric conditioning compositions, and in particular, relates to liquid fabric softener compositions comprising a fluorescer. Background of the Invention 10 Rinse added fabric conditioning compositions are well known. Typically, such compositions comprise a liquid or solid fabric softening agent dispersed in an aqueous medium. The fabric softening agent can be included at up to 8% by 15 weight, in which case the compositions are considered dilute, or at levels from 8% to 60% by weight, in which case the compositions are considered concentrated. One of the problems frequently associated with conventional 20 fabric conditioner compositions is that, upon'repeated use, yellowing can occur. It has been suggested in the prior art to address this problem by incorporating a fluorescent dye, such as the salt 25 of a diaminostilbene (DAS) derivative, within the fabric conditioning composition. However, as this is an anionic compound, it can adversely affect the performance of the softening compound when such a compound is cationic. Also, any complex with a cationic softening compound may give 30 reduced stability against photodegradation. Thus, it may decompose and lose any fluorescing benefits. WO 2006/013033 PCT/EP2005/008074 - 3 - Increasingly, clear fabric conditioning compositions are desired by the consumer. Therefore, it is desirable to provide a clear composition which has a greatly enhanced appearance. 5 WO 98/52907 describes a cationic fabric conditioning composition which may optionally be clear and may contain a diaminostilbene derivative fluorescer. The diaminostilbene fluorescer is classified as hydrophilic. 10 However, this does not -address the problem of providing a clear or translucent liquid fabric conditioning composition comprising a cationic softening compound and a fluorescer which is stable to photodegradation. Objects of the Invention Thus, the present invention seeks to address one or more of the above-mentioned problems, and, to give one or more of 20 the above-mentioned benefits desired by consumers. Surprisingly, we have found that a clear or translucent fabric conditioning composition comprising a fluorescer of the type defined in claim 1 is stable against 25 photodegradation. Furthermore, we have found that such a composition provides a greatly enhanced appearance to the clear or translucent composition. Also, it provides increased stability against 30 photodegradation for other products (when present) in the composition, e.g. dyes and perfumes. 02-06-2006 EP0508074 C4391 (C) COM Summary of the Invention According to the present invention there is provided a stable, pourable clear or translucent fabric conditioning 5 composition comprising: (i) one or more cationic fabric softening materials having an iodine value of from 5 to 140; 10 (ii) from 11 to 70 % by weight of one or more oils, (iii) one or more hydrophobic fluorescers solubilieed in the organic phase of the composition, 15 (iv) optionally one or more low molecular weight solvents. wherein the weight ratio of cationic softening material to oil, is in the range 5:1 to 10:1 and the weight ratio of 20 cationic softening material is low molecular weight solvent when present is in the range 8:1 to 1:3. According to a further aspect of the invention, there is provided a method of conditioning fabrics comprising 25 contacting the above-mentioned fabric conditioning composition with fabrics. In the context of the present invention, the terra "comprising" means "including”. That is the steps, 30 components, ingredients, or features to which the term “comprising" refers are not exhaustive 02-06-2006 EP0508074 C4391 (C) COM Detailed Description of the Invention The present invention is particularly concerned with clear 5 or translucent liquid fabric softening compositions. Such a product is preferably, though not essentially, a microemulsion. That is a product which is isotropic and thermodynamically stable over a specified temperature range. 10 15 Fluoresce!- The clear or translucent composition of the present invention comprises a fluorescer which is hydrophobic. By hydrophobic it is meant that the fluorescer has a hydrophobic!ty, measured by ClogP, of 3 to 50, more preferably 4 to 50, most preferably 5 to 50, e.g. 6 to 50 2 0 ClogP is measured using the "ClogP" program (calculation of hydrophobicities as logP (oil/water)) version 4.01, available from Daylight Chemical information Systems Inc of Irvine California, USA. .02-06-2006 EP0508074 C4391 (C) COM - -A commercially available fluorescer of this type is Blankophor DCB (4- [3-(4-chlorophenyl)-4,5-dihydro-lh-pyrazol-l-yl]benzenesulphonamide), ex Bayer. the a 5 The fluorescer is solubilised in the organic phase of composition. It has been observed that this provides greater deposition of the fluorescer onto synthetic materials, e.g. polyesters, than if the fluorescer is solubilised in the aqueous phase of the composition. 10 Typically, the fluorescer is present at a level of from 0.001 to 2wt%, more preferably from 0.003 to 1.5wt%, most preferably from 0.004 to lwt%, e.g. 0.005 to 0.8wt%, based on the total weight of the composition. 15 Excluded Fluorescers Hydrophilic fluorescers, as described below, are not suitable for use in the compositions of the present 2 0 invention. Diaminostilbene disulphonic acid type fluorescers (hereinafter referred to as "DAS") are classified as hydrophilic in WO-A-98/52907. A commercial example of a DAS 25 is Tinopal DMS (ex CTBA) . Another type of hydrophilic fluorescer is a distyrylbiphenyl fluorescer (hereinafter referred to aa *DSBP*). A commercial example of this type of fluorescer is Tinopal 30 CBS-X (also ex CIBA). WO 2006/013033 PCT/EP2005/008074 - 7 - These materials were introduced, as purchased, at a level of 0.1wt%, into a standard concentrate fabric softening composition (Comfort Concentrate, purchased UK 2004) and a clear fabric softening composition (Lenor Enhancer, 5 purchased UK 2004) by post-dosing and stirring. In both cases, the fluorescer formed large clumps of yellow solid particles. Thus, they do not form stable compositions, as is required by the compositions of the present invention. 10 Without wishing to be bound by theory, it is believed that both DAS and DSPB fluorescers complex with cationic materials, e.g. cationic softening agents, that are typically present in softening compositions forming insoluble floes.

Of course, the cis-.trans isomer weight ratios can be controlled during hydrogenation "by methods known in the art such as by optimal mixing, using specific catalysts and 30 providing high H2 availability. 02-06-2006 EP0508074 C4391 (C) COM - 12 - Saturated andunsaturated fatty acids/acyl compounds may be mixed together in varying amounts to provide a compound having the desired iodine value. 5 Iodine Value of the Parent Fatty Acid The method for calculating the iodine value is as described on page 12 lines 6 to 28 of WO-Al-Oi/04254, the contents of which are incorporated herein. 10 Oils The compositions of the present invention comprise at least one oil. The oil may be a mineral oil, an ester oil and/or 15 atural oils such as vegetable oils. However, ester oils or mineral oils are preferred. The ester oils are preferably hydrophobic in nature. They include fatty esters of mono or polyhydric alcohols having 2 0 from 1 to 24 carbon atoms in the hydrocarbon chain, and mono or polycarboxylic acids having from 1 to 24 carbon atoms in the hydrocarbon chain, provided that the total number of carbon atoms in the ester oil is equal to or greater than 16, and that at least one of the hydrocarbon chains has 12 25 or more carbon atoms. Suitable ester oils include saturated ester oils, such as the PRIOLUBES and BSTOLS (ex.

The dispersion aid assists the 5 ispersion of the micro-emulsion when it is diluted in water. Especially preferred dispersion aids for use in the compositions of the invention are alkoxylated nonionic fatty 10 aohols, such as C10-C22 alkyl/alkenyl alkoxylated with 3-20 moles alkoxy moieties. The fatty alcohols may be alkoxylated with ethylene oxide, propylene oxide or ethylene oxide/propylene oxide mixtures. 15 Other dispersion aids which may be used in the compositions of the invention can be selected from mono-long chain alkyl cationic quaternary ammonium compounds and mono-long chain alkyl amine oxides. 20 Preferably the concentration of the dispersion aid is from 0.05-30% by weight, more preferably from 0.3-20% by weight, most preferably from 1-15% by weight, based on the total weight of the composition. 25 The dispersion aid may also act as a stabiliser for the micro-emulsion so that addition of the dispersion aid provides a more stable micro-emulsion product. The weight ratio of the quaternary cationic softening 30 ompound to the total amount of dispersion aid is from 3:1 to 8:1, more preferably 5:1 to 7:1. WO 2006/013033 PCT/EP2005/008074 - 17 – Anti-Qxidation/Reduction Stabilisers The compositions of the invention may, optionally, comprise one or more additional stabilisers which stabilise against 5 oxidation and/or reduction.
