Definitions

  • This invention relates to powdered laundry detergent compositions that include a shading dye or fabric substantive dye, it relates particularly to inclusion of a shading dye granule into an essentially uncoloured detergent composition.
  • White fabrics may be treated with dye in order to enhance whiteness.
  • the dye used is typically blue or violet. When these treated fabrics have been repeatedly washed with a detergent composition the dye may be removed from the fabric, leading to yellowing of the fabric.
  • WO 2005/003274 describes a laundry treatment composition which comprises a surfactant and from 0.0001 to 0.1 wt% of a combination of dyes which together have a visual effect on the human eye as a single dye having a peak absorption wavelength on cotton of from 540 nm to 650 nm, preferably from 570 nm to 630 nm, the combination comprising a photostable dye which is substantive to cotton.
  • a dye or combination of dyes may be referred to as a shading dye.
  • WO 2005/003275 teaches that such a shading dye may be incorporated into a treatment composition in a variety of ways. For example, dyes that are not sensitive to heat may be included in a slurry and spray dried. Alternatively the dye may be incorporated into granules that are post-dosed to a detergent powder. However, it has been found at higher concentrations of shading dye in the granules of this type that there could be a danger of spotting and dye damage on the clothes. WO 2005/003275 suggests that these problems may be avoided if the concentration of dye in the granules is less than 0.1 wt%.
  • Granules may be formed by loading an inorganic salt with soluble dye solution.
  • a problem with this is that the solution may leak from the granule when it is mixed with the remainder of the laundry detergent composition. This is especially likely if the composition is moist and/or warm: for example, during storage. The phenomenon of leaking of the dye into the surrounding composition is termed bleeding. It is a particularly significant problem for pale coloured or uncoloured detergent powder compositions.
  • Coloured granules containing a dye have also been used in detergent powder formulations as coloured speckles to provide visual cues. These granules or particles are large and contain as little dye as possible due to its nonfunctional nature. The dye is not fabric substantive and a shading dye is therefore unsuitable for this purpose.
  • EP 0336 635 describes a process for preparing a coloured granular alkali metal silicate. This is a visual cue type of speckle and uses a non-substantive dye. Non- substantive dyes may be incorporated at a higher level without fear of spotting damage if the dye granule comes into direct contact with a fabric. It is stated in this document that the amount of colorant in the speckle granule should be low, so as not to interfere with the washing process.
  • the process involves spraying the inorganic material with dye or pigment and a solvent. It is taught that the silicate may be mixed with other inorganic materials such as zeolite, sodium sulphate or sodium phosphate.
  • the preferred particle size of the coloured granules is 0.8 to 1.6 mm.
  • the dye is suggested to be incorporated at a low level: 0.1 to 2 wt% of the granules and it is said to be present as a coating on the silicate.
  • WO 2000/27980 also relates to visible speckles.
  • the particle size being preferably 500 to 1440 mu m.
  • the speckle comprises a dye on a crystalline material that can be a hydrated salt, such as crystalline silicate.
  • the preferred level of dyestuff may be below 0.1 wt% of the speckle particle.
  • US 5073295 relates to coated granules containing, for example, soluble dyestuff.
  • the coatings provide excellent protection against decomposition and separation from other components, for example in detergent compositions.
  • the preferred particle size of the dye granules is 200 to 700 microns .
  • a shading dye granule comprising 0.05 to 0.5 wt% shading dye absorbed onto a hydratable inorganic salt, such as sodium carbonate.
  • a hydratable inorganic salt such as sodium carbonate.
  • sodium carbonate it is preferably a light soda ash with a particle size range such that at least 90% of the particles have a diameter less than 250 microns.
  • the salt may be used in admixture with zeolite in an amount of 0 to 20 wt%.
  • shading dye means one, or a combination of, water-soluble, photostable dyes, substantive to cotton, which, on cotton has a peak absorption wavelength of from 540nm to 650nm, preferably from 570nm to 630nm.
  • Such shading dyes are solid at room temperatures and are typically made into processable liquids by dissolving or dispersing in an aqueous medium.
  • references to quantities of shading dye mean the amount of shading dye solids and not the amount of shading dye solution or dispersion.
  • a method of manufacturing a shading dye granule comprising the steps of dry mixing inorganic carrier materials and then spraying on to the mixture a liquid comprising shading dye and water.
  • Shading dye may be supplied as a dispersion or solution in water. It can be used as supplied or it can be further diluted by adding water. If it is used undiluted, care must be taken about the rate of addition of dye to the inorganic material. If it is used further diluted then the ratio of added water to shading dye solution should preferably be at least 2:1. Dilution of the shading dye with water enables a better control of the amount being added and aids dispersion of the dye over the inorganic solids.
  • the mixing and spraying preferably takes place in a drum mixer.
  • the amount of liquid sprayed on should be less than that which would lead to agglomeration of the inorganic carrier materials. This allows the retention of spare liquid carrying capacity in the inorganic material. It has been found that by retaining at least 10% of the total liquid carrying capacity of the inorganic material the bleeding performance of the granule may be significantly improved.
  • zeolite is added after the initial mixing of the aqueous dye liquid and the inorganic salt. It is also possible to spray the dye onto the zeolite and then dilute this mixture with inorganic salt.
  • a second problem with use of a highly loaded shading dye granule (or adjunct) is that it becomes visible against an uncoloured detergent powder, due to its contrasting colour. In this invention this is mitigated by preventing the agglomeration of shading dye containing particles during the manufacturing process. This is done by limiting the total amount of water and shading dye liquid to 15 wt%, preferably 10 wt%, of the amount of the inorganic salt. As mentioned above, such a limitation also has the advantage that the salt is not fully loaded with diluted shading dye. This means that the bleeding problem is reduced. This is thought to be due to the ability of the shading dye liquid to expand on heating without being forced out of the shading dye granule. Use of these levels of liquid loading also avoids caking problems .
  • the concentration of shading dye (on a solids basis) in the liquid sprayed on should not be greater than 25%, preferably not greater than 10%, most preferably not greater than 2.5%.
  • a typical range of shading dye concentration (solids basis) in the shading dye granule will be 0.05 to 0.4 wt% of the shading dye granule, preferably 0.07 to 0.27 wt%. It has been found that higher levels of shading dye lead to spotting damage if a fabric is left in contact with the powder.
  • lower concentrations of shading dye mean that too high a proportion of shading dye granules need to be added to a powder formulation to obtain the required level of shading dye inclusion in the total formulation. This, in turn, leads to bleeding of the shading dye into the formulation over time.
  • Typical levels of the shading dye granule in the powder formulation are in the range 0.1 to 2.0 wt%.
  • the granule can be used in conjunction with any laundry detergent powder formulations. It is especially useful for use with formulations that are white, or relatively lightly shaded, as these would have suffered particularly from any bleeding that occurs over time.
  • This test is designed to check if a powder containing a shading dye granule gives rise to staining and/or spotting of test fabrics .
  • This test checks shade colour change in finished powders containing shading dye granules.
  • a quantity of shading dye granules is incorporated into a standard detergent powder by mixing in a plastic bag. 30 grams of this product and a reference powder without any shading dye granules are stored in open petri dishes at 37°C/70%r.h. for 4 weeks.
  • a visual comparison against the reference is done weekly to check if any shade colour change is observed. Evaluation is carried out in a visual cabinet under daylight. The classification is:
  • a shading dye granule was manufactured with the ingredients shown below:
  • the shading dye used was an aqueous dispersion of the trisethoxy tripropanol -amine salt of Direct Violet 9.
  • the salt was present at a concentration of about 10 wt% and was stabilised at this level in aqueous dispersion/solution by surfactant and other minor ingredients.
  • the water and dye were mixed together and sprayed onto the light soda ash in a low/medium shear batch mixer, with subsequent addition of zeolite towards the end of the batch cycle. Except where specified otherwise the light soda ash used had 100wt% particles below 250 microns.
