Definitions

  • This invention relates to water-soluble solid fabric freshener compositions comprising water-soluble supports and fragrances. More particularly, it relates to the use of such compositions as additives to rinse solutions to deposit effective amounts of fragrance on laundered fabrics.
  • Modern laundry detergents and fabric conditioners have become complex highly technological products involving combinations of many active materials such as surfactants, bleach activators, peroxides, chelants, builders, dyes, fragrances, conditioner actives, etc. Products involving combinations of laundry detergents and fabric conditioners are commonplace.
  • fabric conditioners are normally added to the rinse water during the final rinse cycle, which is generally of short duration. Consequently, the conditioner must be capable of rapid dispersion in the rinse water so as to produce an effective concentration of product for conditioning in the relatively short period of the rinse cycle. Similarly, when such products are used in the hand washing of clothes, the conditioner must disperse rapidly and easily in cold water.
  • the high cost of laundry powders and fabric conditioners derives from the cost of the actives used in their formulation and from associated transportation and packaging costs. Additionally, as liquid conditioners are mainly composed of water - which, in parts of the world, can be in scarce supply - a premium is paid to both package and transport diluted actives and fragrance within the conditioner.
  • the present invention provides a water-soluble solid fabric freshener composition
  • a water-soluble solid fabric freshener composition comprising:
  • composition of the invention is capable, in use, of depositing an effective amount of fragrance onto laundered fabrics.
  • the deposition of perfume on laundered fabrics is effected by contacting the fabrics with an aqueous solution or dispersion that contains the above-defined fabric freshener composition.
  • the invention provides a method for depositing an effective amount of a fragrance on laundered fabrics comprising:
  • Water-soluble solid fabric freshener compositions in accordance with the mvention can be readily formed into granules capable of rapid dispersion in rinse water at temperatures from 10°C to 30°C.
  • the compositions can be used to deliver fragrance to fabric without the need for additional actives.
  • the water-soluble support is present in an amount between 1 % by weight to 99% by weight, more preferably from 20% by weight to 99% by weight, even more preferably from 70% by weight to 99% by weight, based on the total weight of the composition.
  • the water-soluble support is of material that has a melting point above 45°C and that is water-soluble at water temperatures between 10°C to 30°C, more preferably at water temperatures between 15°C and 25°C.
  • Non-limiting examples of water-soluble support materials useful in the present invention include: alkali metal salts of inorganic acids (such as phosphoric, chloridic and sulphuric,); alkali metal salts of organic acids (such as acetic, citric); quaternary ammonium salts of inorganic and organic acids; low and high molecular weight sugars; porous starches; chemically modified starches; starch derivatives; water-soluble polymers (such as polyethylene glycol, poly vinyl alcohol, cellulose derivatives, poly vinyl pyrrolidones, poly acrylic acid and its derivatives); other organic materials (such as urea etc.); and mixtures thereof.
  • alkali metal salts of inorganic acids such as phosphoric, chloridic and sulphuric
  • organic acids such as acetic, citric
  • quaternary ammonium salts of inorganic and organic acids low and high molecular weight sugars
  • porous starches chemically modified starches
  • starch derivatives water-soluble polymers
  • water-soluble supports of the present invention are: sodium salts of inorganic and organic acids; low molecular weight sugars, such as sucrose; high molecular weight sugars, such as dextrins; organic materials, such as urea; and water-soluble polymers, such as polyvinyl alcohol, polyethylene glycol.
  • Typical water-soluble supports of the present invention will meet the following criteria: (i) water-solubility at 0°C of at least 5 wt%, more preferably 10wt%, most preferably 20wt%; (ii) cheap and readily available in large quantities; (iii) safe at the use level in the product; (iv) neutral colour (e.g. white, cream); (v) compatible with fragrance.
  • the fragrance is preferably present in an amount of at least 0.01 % by weight, more preferably from 0.01% by weight to 40% by weight, even more preferably from 0.1% by weight to 30% by weight, and even more preferably from 0.5% by weight to 20% by weight, based on the total weight of the composition.
  • the fabric freshener composition of the present invention is formulated into granules or tablets.
  • these granules or tablets have a particle size between 0.1 and 5mm, more preferably between 0.3 and 3mm, even more preferably between 0.5 and 2mm.
  • the size distribution is as even as possible to produce an aesthetically pleasing product and avoiding the formation of dust.
  • fragrance is provided to laundered fabrics by contacting such fabrics during a laundering operation with rinse water containing dispersed therein the fabric freshener composition of the present invention.
  • the process of the invention can be conveniently carried out in a washing machine during laundering or by contact of the fabrics with a wash solution or rinse solution during hand washing.
  • the fabric freshener composition of the present invention may be added to the rinse solution in an amount to provide a dosage of from about 0.1 to 10 g/litre, preferably 0.5 to 5 g/litre, and even more preferably 1 to 3 g/litre.
  • the pH of the rinse or wash solution containing the fabric freshener composition of the present invention is between pH 2 and 10, more preferably between pH 3 and 7 and even more preferably between pH 4 and 6.
  • the fabric freshener compositions of this invention lend themselves to packaging and packages may be made of sealed containers containing any desired amounts of such compositions that, being in dry form, may be readily distributed or shipped without difficulty. During such shipment, they do not pack or compress or cake and are directly available without further preparation for use in treating fabrics to impart freshness. Moreover the fabric fresheners of this invention have an additional advantage in that they may be prepared at ambient temperature with rninimum use of water
  • the rinse-stage fabric freshener compositions of the present invention may furthermore contain various additives commonly used in fabric freshener compositions to thereby enhance the aesthetic effects.
  • additives include pigments, fragrance carriers (such as fragrance absorbers and/or fragrance adsorbers), disintegrants, flow aids, emulsifiers, enzymes, optical brighteners, anti-microbial ingredients, bleach systems, easy ironing aids, sequestrants, and so on.
  • fragrance refers to odoriferous materials that are able to provide a pleasing fragrance to fabrics, and encompasses conventional materials commonly used in detergent compositions to counteract a malodour in such compositions and/or provide a pleasing fragrance thereto.
  • the fragrances are preferably in the liquid state at ambient temperature, although solid fragrances are also useful. Included among the fragrances contemplated for use herein are materials such as aldehydes, ketones, esters and the like which are conventionally employed to impart a pleasing fragrance to liquid and granular detergent compositions. Naturally occurring plant and animal oils are also commonly used as components of fragrances.
  • the fragrances useful for the present invention may have relatively simple compositions or may comprise complex mixtures of natural and synthetic chemical components, all of which are intended to provide a pleasant odour or fragrance when applied to fabrics.
  • Fragrances used in detergent compositions are generally selected to meet normal requirements of odour, stability, price and commercial availability.
  • a description of the materials conventionally used in detergent perfumery is set forth by R. T. Steltenkamp, The Journal of The American Oil Chemists Society, Vol. 45, No. 6, pp. 429-432, such disclosure being incorporated herein by reference.
  • fragrance carrier refers to any material that is able to absorb and/or adsorb fragrance and adhere to the water-soluble supports of this invention.

  • Organic carrier materials both solid and liquid, that are compatible with perfume, for example starch, cellulose, other polysaccharides, triethyl citrate, tributyl citrate, dioctyl adipate, isoparaffins, waxes etc.
  • o Polymeric carrier materials both porous and non-porous, such as those disclosed in WO 98/28396, WO 98/28398 and EP 441512, PolyporeTM (marketed by Polypore Inc, Arlington, Arizona), PolytrapTM and MicrospongeTM (both from Cardinal Health, New Jersey, USA) and other porous carriers, such as those disclosed in WO 91/19483 and US 4873091.
  • Preferred materials in this category comprise isobutyl methacrylate as the main polymer, cross-linked with difunctional acrylate cross-linkers and using poly vinyl alcohol as a hydroxy-functional polymer, having a mean particle size in the range 70 to lOO ⁇ m.
  • Such materials can be prepared by the method of Example 2 of WO 98/28396 and WO 98/28398, e.g. as specified in Example 5 of those documents.
  • the fragrance carrier is preferably odourless or of low odour, having no significant odour that would affect the odour of the fragrance.
  • fragrance carrier materials include silicas, sodium tripolyphosphate, bentonite clay and polymer carrier materials disclosed in WO 98/29396 and WO 98/28398, e.g. as discussed above.
  • the fabric freshener composition of the present invention may be in the form of finely divided powders, as well as relatively larger-sized granules, beads or agglomerated particles, and may be produced by diverse methods of manufacture such as spray-drying, dry-blending or agglomeration of individual components.

  • the water-soluble support consists of a crystal material, such as sodium chloride, that is selected to be the desired size by sourcing and/or sieving.
  • a crystal material such as sodium chloride
  • To the crystal material is added, with stirring (using any standard equipment such as V type blenders, ribbon blenders, static mixer cones and double cones), a uniform coating of an outer layer of fragrance, or, if required, a layer of fragrance and fragrance carrier such as sodium tripolyphosphate.
  • the outer layer may also include any pigment or other secondary additives.
  • the inner crystal material defines the size and shape of the fabric freshener composition whilst the outer layer holds the fragrance, and other additives.
  • This method is used when the water-soluble support is able to absorb the fragrance.
  • the water-soluble support is granulated to the desired particle size by any standard granulation method know to those skilled in the art (such as powder layering, wet granulation and fluid bed agglomeration). Over and/or undersized particles are removed if required. Fragrance is then added to the granules with stirring. Flow aids are added if required.
