Definitions

  • the invention relates to a dispensing device for use in washing and fragrancing fabric in a washing machine.
  • Dispensing devices for fragrancing laundry fabrics are known .
  • EP1526876 discloses a fragrance release system with a container and a plurality of particles which preferably comprise a polymer carrier material as well as at least one scent and are received in the receiving space of the container.
  • the receiving space has a crescent-like cross- sectional shape with an outwardly curved front wall.
  • the receiving space is completely filled with particles.
  • An objective of the present invention is to provide an improved device which can be used for improved fragrancing and conditioning the laundry fabrics in a washing machine.
  • a bi-functional dispensing device containing a low soluble perfume carrier comprising both perfume and a conditioning agent for dispensing during multiple wash cycles.
  • the invention provides a process for conditioning and fragrancing laundry fabrics in a washing machine by employing the dispensing device of the first aspect, inserting the dispensing device into the washing machine drum together with the laundry fabrics and then performing a laundry treatment operation.
  • a dispensing device according to the first aspect of the invention and instructions for use according to the method of the second aspect of the invention.
  • the perfume is automatically and separately dosed throughout the washing process (due to low solubility) .
  • the carrier also performs an additional conditioning function and so the invention provides minimal or no waste in terms of non-functional perfume delivery ingredients.
  • the decoupling of perfume and conditioning from the dispensing of main wash composition allows for enhanced fragrance and conditioning delivery during e.g. the rinse cycle where detergent concentration is low. Perfume deposition drops dramatically with increase in surfactant concentration and so release of the perfume during e.g. the rinse cycle enables greatly improved perfume delivery.
  • a further advantage is that the device allows delivery of certain perfumes which are incompatible with main wash detergent ingredients, such as hydrolysing and pH- sensitive perfumes.
  • the low solubility (in water) of the perfume carrier provides slow release of perfume so that the device is reusable over multiple wash cycles in so far as perfume delivery is concerned.
  • the perfume is preferably bound in a solid form, which can further control the perfume delivery in water.
  • the solubility limits may be selected per wash cycle depending how much perfume is to be delivered.
  • the amount of carrier dissolved depends on the length of the wash and the temperature of the wash.
  • Advantageously delivery levels per standard load wash lie in the range 0.05 to 0.5g. This sets the solubility limits of the carrier to between 0.2g to 2g per wash for a carrier containing 20% by weight perfume and a 4O 0 C wash programme.
  • the delivery level per standard load wash are in the range of 0.5 to 5 g per wash, since this provides conditioning sufficient to counter act the harshening effect of the main wash detergent and for conditioning the fabrics.
  • the solubility of the perfume carrier conditioner is preferably defined as rate of weight loss in a 100ml Linirig pot test at 4O 0 C and is in the range of 10-35% of the total composition .
  • the perfume carrier may comprise soaps, clays, silicones or waxes or combinations thereof.
  • the carrier should be selected for low solubility, optimum hardness and have no negative minimal/no effect on perfume perception.
  • Auxiliary components such as non ionic surfactants may be used to control solubility etc.
  • the device may comprise the perfume carrier such that the carrier is contained within at least a part of the device such as a housing receptacle, pouch etc.
  • the device may comprise any suitable insoluble plastic able to withstand normal washing temperatures.
  • the device preferably has apertures to allow release of the perfume carrier and conditioning agent into the wash.
  • the perfume carrier may comprise a three-dimensional shape and may be a sphere, hemisphere or "stretched sphere" in the form of an ellipse.
  • Further possible shapes are cubes, cuboids and corresponding three-dimensional elements having flat side surfaces, and also in particular cylindrical embodiments with circular or oval cross section.
  • Further possible three-dimensional shapes are regular polyhedra, for example tetrahedra, hexahedra, octahedra, dodecahedra, icosahedra.
  • decorative shapes of sea shells, fruits, and flowers are also conceivable are decorative shapes of sea shells, fruits, and flowers.
  • the perfume carrier may be a shaped body, which shape is achieved by moulding and/or stamping; extrusion, injection molding or spraying to give granules. Stamping is advantageous for its contribution to increasing hardness of the composition which in turn allows control of solubility.
  • the carrier may be moulded, adhered (e.g. by heat sealing, water-insoluble adhesive) etc. to/in/as part of the device.
  • the carrier has a generally solid consistency at room temperature, i.e. dimensionally stable and not free-flowing.
  • the mass needs to be selected so that repeated use is allowed.
  • the shaped body/bodies may be lmm-lOcm diameter and preferably 3-7 cm diameter. Where pluralities of shaped bodies are used, these may have uniform diameter or alternatively they may be differently sized but within the above ranges.
  • the device may be a flexible or rigid device.
  • the device may comprise a mesh or net-like material providing dispensing apertures for passage there through of dissolved, eroded carrier into the wash liquor.
  • the dispensing apertures may be from 0.5mm to 20mm.
  • the device may comprise a flexible bag.
  • the device may be rigid or semi-rigid or at least be self supporting.
  • the material of the device may be any suitable material such as polyester (ideally suitable for net/mesh constructions) and other plastics.
  • the net/mesh may also be made e.g extruded or woven from fibres extruded from the polymeric carrier of the invention perfume.
  • the dispensing device is re-usable, and is produced from a material capable of withstanding temperatures for the machine washing or drying of laundry, especially up to 150 0 C.
  • the net material one example is sold under the trade name NETLON. However other materials capable of withstanding the above temperatures are envisaged.

  • the general description of the perfumes which can be used is a general representation of the different classes of odorant substances.
  • an odorant In order to be perceptible, an odorant must be volatile, for which an important role is played not only by the nature of the functional groups and by the structure of the chemical compound but also by the molar mass. Thus, the majority of odorants have molar masses of up to about 200 daltons, while molar masses of 300 daltons or more tend to be an exception. On the basis of the different volatility of odorants there is a change in the odour of a perfume or fragrance composed of two or more odorants during its evaporation, and the perceived odours are divided into top note, middle note or body, and end note or dryout .
  • the top note of a perfume or fragrance mixture does not consist only of volatile compounds, whereas the base note consists for the most part of less volatile odorants, i.e., odorants which adhere firmly.
  • the composition of perfumes it is possible for more volatile odorants, for example, to be bound to certain fixatives, which prevent them from evaporating too rapidly.
  • the subsequent classification of the odorants into "more volatile” and "firmly adhering" odorants therefore, states nothing about the perceived odour and about whether the odorant in question is perceived as a top note or as a middle note.
  • fragrances and perfume oils mentioned can in this way allows both the product odour directly on opening the brand new composition and the use fragrance, for example when used in a washing machine, for the inventive composition to be influenced.
  • These perceived fragrances may of course be the same but they may also be different. It is advantageous to use more firmly adhering odorants for the latter perceived odour, while more volatile odorants can also be used to fragrance the product.

As the perfume becomes depleted, the carrier may show less colouration and/or increased transparency. In this way the consumer knows when to replace the device. Hydrolysable dyes may be used for this purpose. The dyes should be suitable for colouring the carrier material.
