Definitions
- the present invention relates a detergent dispensing cartridge for use with a washing machine.
- a detergent dispensing cartridge for use with a washing machine, wherein the washing machine is for cleaning a soiled substrate, comprising the treatment of the moistened substrate with a formulation comprising a multiplicity of polymeric particles, the cartridge holding a cleaning formulation, which comprises: - a) 15-35wt% anionic surfactant;
- washing machine any vessel / machine (whether manually operated or fully / partially automated) which is capable of being used in a washing operation is intended.
- the washing machine is preferably an automatic clothes washing machine.
- Most preferably the washing machine is one which has been modified such that it operates using the technology of one or more of the co-pending patent applications WO2007/128962, GB 0902619.6, GB 0907943.5, GB 0916249.6, GB 0916250.4, GB 0920565.9, GB 1002245.7, and GB 1006076.2; the disclosures of which are incorporated by reference.
- the ratio of beads to substrate is generally in the range of from 30: 1 to 0.1 : 1 w/w, preferably in the region of from 10: 1 to 1 : 1 w/w, with particularly favourable results being achieved with a ratio of between 5 : 1 and 1 : 1 w/w, and most particularly at around 2: 1 w/w.
- 10 g of polymeric particles would be employed
- the polymeric particles are of such a shape and size as to allow for good flowability and intimate contact with the textile fibre.
- a variety of shapes of particles can be used, such as cylindrical, spherical or cuboid; appropriate cross-sectional shapes can be employed including, for example, annular ring, dog-bone and circular.
- the particles may have smooth or irregular surface structures and can be of solid or hollow construction.
- Particles are preferably of such a size as to have an average mass in the region of 5 to 100 mg, preferably from 10 to 30 mg.
- the preferred average particle diameter is in the region of from 0.5 to 6.0 mm, more preferably from 1.0 to 5.0 mm, most preferably from 2.5 to 4.5 mm, and the length of the beads is preferably in the range from 0.5 to 6.0 mm, more preferably from 1.5 to 4.5 mm, and is most preferably in the region of 2.0 to 3.0 mm.
- Said polymeric particles may comprise any of a wide range of different polymers. Specifically, there may be mentioned polyalkenes such as polyethylene and polypropylene, polyesters and polyurethanes, which may be foamed or unfoamed. Preferably, however, said polymeric particles comprise polyamide or polyester particles, most particularly particles of nylon, polyethylene terephthalate or polybutylene terephthalate, most preferably in the form of beads. Said polyamides and polyesters are found to be particularly effective for aqueous stain/soil removal, whilst polyalkenes are especially useful for the removal of oil-based stains. Optionally, copolymers of the above polymeric materials may be employed.
- nylon or polyester homo- or co-polymers may be used including, but not limited to, Nylon 6, Nylon 6,6, polyethylene terephthalate and polybutylene terephthalate.
- the nylon comprises Nylon 6,6 homopolymer having a molecular weight in the region of from 5000 to 30000 Daltons, preferably from 10000 to 20000 Daltons, most preferably from 15000 to 16000 Daltons.
- the polyester will typically have a molecular weight corresponding to an intrinsic viscosity measurement in the range of from 0.3-1.5 dl/g, as measured by a solution technique such as ASTM D-4603.
- the polymeric particles comprise nylon chips, e.g. Nylon 6 or Nylon 6,6.
- a cartridge allows discharge of a detersive composition into a washing machine (over multiple wash cycles) where the consumer has no need to measure the detersive composition or come into contact with same yet have the security of knowing that the correct detersive composition has been applied to the wash load of the machine.
- each compartment may be activated separately such that the contents of each compartment may be released separately / sequentially.
- Each compartment may be designed such that it holds a bespoke complete detergent formulation or a formulation that focuses upon a single active component of a detergent formulation. It is preferred that each compartment may be activated separately; either in completely individual activation or in a "program" that activates one or more compartments at pre-defined portions of a wash cycle so that a portion of the compartment content may be released. In this way it has been found that the detergent release can be tailored to suit a particular wash load in terms of its size, compositions and type of staining present thereon. Clearly it is envisaged that a particular compartment may be activated once, not at all or a plurality of occasions in a wash cycle.
- DTIs dye fixatives / dye transfer inhibitors
- anionic surfactants which are typically employed in detergents (especially laundry detergents to provide cleaning function).
- the dye fixatives / DTIs and the anionic surfactants "couple" together because of their opposing charges, compromising their respective functions.
- the temperature / heating of the wash liquor may be tailored such that it is optimized to work with the contents of the compartment being released at that juncture.
- a bleach / bleach activator composition is released heating of the wash liquor (e.g. to around 40-60°C) may be appropriate to ensure that optimal functioning of the bleach / bleach activator composition occurs.
- many of the other detergent components require no wash liquor heating to achieve their optimal function.
- the entire wash liquor or a portion thereof may be heated. Where only a portion of the wash liquor is heated the portion may be a portion of the wash liquor which is passing through r adjacent to the cartridge or the portion passing through or adjacent to any wash liquor circulation system.
- the containment / release in separate compartments allows the pH of the wash liquor may be tailored such that it is optimized to work with the contents of the compartment being released at that juncture.
- a bleach / bleach activator composition is released raising of the pH of the wash liquor (e.g. to an alkaline pH by release of a suitable pH modifying agent) may be appropriate to ensure that optimal functioning of the bleach / bleach activator composition occurs.
- many of the other detergent components require no pH adjustment to achieve their optimal function.
- release of individual detergent actives may be tailored such that it is optimized to work with the system of WO2007/128962.
- one preferred release profile is in the following order: - a) Release of an enzyme containing formulation;
- Composition (b) and / or (c) may also contain a surfactant.
- the oxidising formulation may contain a bleach and / or a bleach activator / catalyst.
- Composition (b) preferably comprises a) 5-25wt% anionic surfactant
- a detergent dispensing cartridge for use with a washing machine, wherein the washing machine is for cleaning a soiled substrate, comprising the treatment of the moistened substrate with a formulation comprising a multiplicity of polymeric particles, the cartridge having multiple compartments; a first compartment holds a enzymatic cleaning formulation; which comprises a) 15-35wt% anionic surfactant;
- 0.1-10wt% enzyme and optionally other detergent auxiliary components. and a second compartment holds an oxidising cleaning formulation; which comprises a) 5-25wt% anionic surfactant;
- oxidising agent / bleach 0.1-40wt% oxidising agent / bleach; and optionally other detergent auxiliary components.
- step (d) occurs at the end of the washing machine cycle, during the rinse phase.
- dye fixative / DTI are generally "quaternary" molecules (i.e. including at least one N + moiety), as such they could cause precipitation in presence of anionic surfactants.
- dye fixative / DTI could fix the stains (e.g. to the material being cleaned).
- the polymeric particles used may be present throughout the entire laundry washing cycle or only for a portion thereof. Where the polymeric particles are only present for a portion of the washing cycle it is preferred that the polymeric particles are removed form the washing area of the washing machine at a rinse cycle (preferably a final rinse cycle) of the washing machine operation.
- the cartridge may comprise compartments for release of some detersive components in a pre-wash cycle (which may be before the beads are added to the machine) of the washing machine operation. This has been found to be beneficial with certain detergent components, the activity of which may be compromised by adsorption on the polymeric particles.
- the cartridge may comprise compartments for release of some detersive components in a rinse cycle (preferably a final rinse cycle) of the washing machine operation. This has been found to be beneficial with certain detergent components, the activity of which may be compromised by adsorption on the polymeric particles.
- Preferred examples of detersive components for release at this stage (and for which there is preferably a compartment in the cartridge) are optical brighteners and fragrances.
- the cartridge compartments may be modular, e.g. one or more compartments of the cartridge may be replaceable without replacing the entire cartridge. Equally it is preferred that a consumer may select which compartments are most suitable for their kind of typical washing so that a complete cartridge may be constructed using the compartments that they are most like to require in their washing.
- Each compartment may have a volume of from 1 to 5000 cc, more preferably from 10 to 900 cc, more preferably from 20 to 600 cc, more preferably from 20 to 400 cc, more preferably from 20 to 300 cc, more preferably from 20 to 200 cc and most preferably from 20 to 100 cc.
- the positioning of the cartridge in the washing machine is flexible. Clearly it is preferred that the cartridge is positioned such that the cartridge contents can be dispensed into the area of washing of the washing machine.
- a conduit may be present to connect the cartridge output to the washing area.
- the cartridge may be positioned such that its output is adjacent to or connected to fresh incoming wash fluid (e.g. water).
- the cartridge may be positioned / the washing machine may be designed such that fresh incoming wash fluid / wash liquor flows over / around the device.
- the cartridge compartment activation may be operated by one or more of a number of mechanisms. Different activation mechanisms may be used for different compartments of the cartridge.
- Preferred operation mechanisms may be manual or non-manual mechanisms.
- Preferred non-manual operation mechanisms include physical and chemical activation triggers associated with changes within the washing cycle).
- Preferred examples include time, temperature / temperature changes, smell/ odour, humidity / water presence (or some other associated property of the cleaning liquor, e.g. such as ionic strength or pH), drum rotation / centrifugal force or other force.
- Other operation mechanisms may arise from a result of a conduit from the cartridge to the washing machine (particularly the washing machine operating schematics) such that the operation of the washing machine, triggered by the schematics of the washing machine, influences or causes operation of one or more of the compartments or the cartridge at one or more time points within the washing cycle. In this way different washing cycles may triggers different activation / operation of the cartridge / compartments thereof. Additionally different wash loads / conditions may trigger a differential degree of operation of one or more compartments.
- the cartridge may also have a manual override which can be accessed by a consumer.
- This manual override may overcome any normal dispense activity of the cartridge and influence the dispensing such that the release of one or more compartments is increased / reduced and / or the timing of the release is affected.
- the entire contents of a compartment may be discharged in a single wash cycle, either in one part of a single wash cycle or at multiple parts thereof. More preferably the contents of a compartment may be released over a plurality of wash cycles, e.g . over 10-30 wash cycles (such as about 20 wash cycles) for added convenience to a consumer. In this case the cartridge contents may still be released at multiple points over a plurality of cycles.
- the cartridge and / or one or each compartment thereof may have an "end-of-life" indicator to make sure that a consumer is aware that the contents of one or more compartment has been exhausted and needs to be replenished.
- the end-of-life" indicator may be triggered by or arise through liaison with the schematics of the washing machine Equally in one embodiment of the device the cartridge is intended for a single washing cycle.
- Compartment release operation may be by one or more of a number of mechanisms.
- Preferred compartment release mechanisms include manual release (e.g. opening, squeezing), gravitational release, active release (e.g. by a motor / pump, such as a powered motor, wax motor, piezo, injection or spray) and passive release driven by a flow or wash liquor / polymeric particles through or adjacent to a compartment drawing the contents of the compartment (or a portion thereof) there from.
- the release may be combination of active and passive mechanisms, e.g . an access means to a compartment may be opened under a certain condition to allow release of an active from a compartment.
- a preferred example of such an activating mechanism is a bimetallic driven opening means such that the opening means is activated at a certain predetermined temperature to allow release (by whatever mechanism) to occur.
- detersive components (and associated compartments) which make up a smaller portion of the entire detersive formulation e.g. fragrances, optical brighteners
- more active dispensing methods e.g. spraying
- more passive dispensing methods may be preferred.
- compartment contents may be in any suitable physical form.
- Preferred forms include liquids (dispersions, suspensions, pastes, solutions and emulsions, gels) and solids (solidified gels, powders, tablets).
- solids solidified gels, powders, tablets.
- the content of differing compartments may be in differing physical forms.
- the compartment contents may be contained in a secondary packaging, e.g . such as an encapsulation means, pouch or sachet.
- the compartment contents may be refillable.
- the refill contents may be in the form of granules, powders, or liquids / gel dependent on the chemical / physical nature of the nature of the composition for the / each compartment.
- the refill composition may be in the form of a "unit-dose" composition, e.g. a compressed / solidified / moulded tablet or the refill may be package in a film pouch wherein the film may be entirely water soluble / dispersible or have a water soluble potion or pierce-able section to allow release of the pouch contents.
- the film pouch may comprise a metallic foil or a plastics material, e.g. polypropylene, polyethylene, polyvinylalcohol, ABS, PET, polyamides, PMMA or PC.
- the unit dose composition will be sized to fit the respective compartment and allow ease of refilling without exposing a consumer to any harmful chemicals.
- a plurality of unit-dose entities may fit in one compartment; such an arrangement may have a separate support frame associated
- the cartridge may contain one or more actives directed to increasing the activity of the polymeric particles.
- one preferred active is a plasticiser for the polymeric particles. It is postulated that with the use of such a plasticiser the Tg of the polymeric particles would be lowered such that the polymeric particles would be more active at lower temperatures.
- the formulation may include sacrificial agents that are absorbed onto sites on the polymeric particles, wherein these sites would otherwise cause detrimental adsorption of one or more detersive active.
- the cartridge may include a compartment which contains (supplementary) polymeric particles. These particles may be purely polymer or may have been physical or chemically altered to affect their activity. Preferred means of chemical alteration include polymeric particles into which a detersive active has been reversibly / irreversibly adsorbed (e.g. enzyme, bleach catalyst) or upon which a detersive active has been coated.
- a detersive active e.g. enzyme, bleach catalyst
