Definitions

  • a detergent dispensing cartridge for use in 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, wherein said formulation is free of organic solvents, the cartridge having multiple compartments; a first compartment holds a first detergent formulation; and a second compartment holds a second detergent formulation, wherein a portion of the contents of the first compartment is released before a portion of the contents of the second compartment is released.
  • 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 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.
  • 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.
  • one preferred release profile is in the following order: - a) Release of an enzyme containing formulation;
  • 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.
  • 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
  • detersive components (and associated compartments) which make up a larger portion of the entire detersive formulation e.g. surfactants, builders
  • more passive dispensing methods may be preferred.
  • the 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). In a cartridge the content of differing compartments may be in differing physical forms.
  • the overall detersive formulation may be altered because of the presence of the polymeric particles.
  • One example of an alteration is that the overall amount of detergent required per wash cycle is considerably lower. Indeed in this regard it has been found that the amount of detergent required may be as low as 50%, 40%, 30%, 20% or even 10% of the amount that would ordinarily be expected for a clothes washing operation in an automatic laundry washing machine.
  • an equivalent washing standard can be achieved for a 5kg load of laundry in an automatic laundry washing machine using as little as 15g of a liquid detergent formulation (whereas in a conventional washing process in an automatic laundry washing machine 150g of the same liquid formulation would be required).
  • the amount of washing water used in a wash cycle is preferably around 6 litres per kilo of wash load; with around 3 liters for the washing stage(s) and 3 litres for the rinsing stage(s).
  • the amount of water can be lower, e.g. preferably between 2.5: 1 and 0.1 : 1 litres per kilo of wash load; more preferably, the ratio is between 2.0: 1 and 0.8: 1 litres per kilo of wash load, with particularly favourable results having been achieved at ratios such as 1.5: 1, 1.2: 1 and 1.1 : 1 litres per kilo of wash load.
  • Examples of primary alkyl sulfate surfactants are those of formula : ROS0 3 ⁇ M + wherein R is a linear C8-C20 hydrocarbyl group and M is a water-solubilising cation.
  • One or more additional ingredients may optionally be comprised.
  • These include conventional detergent components such as further surfactants, bleaches, bleach enhancing agents, builders, suds boosters or suds suppressors, anti-tarnish and anti-corrosion agents, organic solvents, co- solvents, phase stabilisers, emulsifying agents, preservatives, soil suspending agents, soil release agents, germicides, anti-microbial / antibacterial agents, phosphates such as sodium tripolyphosphate or potassium tripolyphosphate, pH adjusting agents or buffers, non-builder alkalinity sources, chelating agents, clays such as smectite clays, enzyme stabilizers, anti-limescale agents, colourants, dyes, hydrotropes, dye transfer inhibiting agents, brighteners, and perfumes. If used, such optional ingredients will generally constitute no more than 10 wt%, for example from 1 to 6 wt%, the total weight of the cartridge contents.
