A method for applying these compositions during the wash cycle of a laundry process as well as the use of these particles to reduce clothes damage is also included.

Description

LAUNDRY TREATMENT COMPOSITIONS
FIELD OF INVENTION
The present invention relates to wash added, laundry detergent compositions and methods for using the same during the wash cycle of a consumer laundry process.
BACKGROUND
Coloured clothes are extremely popular with consumers. To remove dirt on washing, the clothes are vigorously agitated in water with a washing formulation. This process leads to damage on the surface of the clothes, which reduces their aesthetic appeal. This damage is particularly a problem when granular laundry compositions are used.
WO 2007/111887 (Proctor & Gamble) discloses liquid compositions comprising hueing dye and a pearlescent agent. The pearlescent agent is added to counteract the darkening effect of the hueing dye on the appearance of the liquid composition. The pearlescent agent may be organic or inorganic in nature, with glass or metal oxide coated glass being disclosed.
US 4,051,046 (Procter & Gamble) discloses detergent compositions comprising surfactant and low concentrations of substantially water-insoluble particulate material with a range of 1 to 50 micrometers for providing fabric benefits. The document also discloses that the use of particulate water-insoluble materials having an average diameter of more than about 50 micrometers will not procure the mentioned fabric benefits.
SUMNLARY OF INVENTION
We have found that Siθ2 particles provide improved colour care by reducing damage caused by fabric laundering.
In one aspect the present invention provides a granular laundry treatment composition containing less than 1 wt . % of phosphate comprising:
(i) from 0.1 wt . % to 40 wt.%, preferably 0.5 to 5 wt. %, of a spherical Siθ2 particle, the Siθ2 particle having a size in the range from 0.1 to
5000 microns;
(ii) from 2 to 70 wt.% of a surfactant; and,
(iii) from 1 to 50 wt.% of a builder.
Preferably the spherical Siθ2 particle is chosen from sand, therein having a size in the range of 1 to 2000 microns, and/or glass, therein having a size in the range of from 100 to 2000 microns.
A second aspect of the invention provides a domestic method of treating a textile, the method comprising the steps of:
(i) treating a textile with an aqueous solution of from 1 to 20 g/1 of the composition of the first aspect; and,
(ii) rinsing and drying the textile. A third aspect of the invention provides the use of spherical Siθ2 particles to reduce damage to clothes being laundered during a domestic main wash process.
Preferably in the aforementioned use, the spherical Siθ2 particle is chosen from sand, therein having a size in the range of 1 to 2000 microns, and/or glass, therein having a size in the range of from 100 to 2000 microns.
DETAILED DESCRIPTION OF THE INVENTION
The amount of components in the granular laundry treatment composition quoted herein are wt . % of total composition unless otherwise stated.
The spherical Siθ2 particles should have a roundness (ratio of axes) of >80%, preferably >94%. The roundness (ratio of axes) is a measurement of the length/width relationship with values in the range 0 - 1. The length is the shortest axis and the width is the longest axis. A perfect circle has a roundness value of 1.0 and a thin rectangle values approaching 0. To calculate the roundness, images of the particles should be taken, preferably with a suitable microscope, for example a PharmaVision 830 available from Malvern™.
The spherical Siθ2 particle is preferably chosen from sand, therein having a size in the range of 1 to 2000 microns, and/or glass, therein having a size in the range of from 100 to 2000 microns. Preferably the size of the spherical Siθ2 particle is 100 to 2000 microns, more preferably 100 to 1000 microns, even more preferably 100 to 500 microns, for example 100 to 200 microns .
The size of the spherical Siθ2 particle is measured using graded sieves and it is that which is retained or passes through such sieves.
The spherical Siθ2 particle comprises Siθ2 at a level of from 50 to 100 wt. %, preferably from 55 to 100 wt.%, more preferably from 65 to 100 wt.%. Alternatively, the Siθ2 particles may contain other components, examples of such being Na2<0, CaO and MgO. If present at all, the other components are preferably present at 45 wt.% or less, more preferably 35 wt.% or less based on wt.% of the Siθ2 particle .
SURFACTANT
The composition comprises between 2 to 70 wt.% of a surfactant, most preferably 10 to 30 wt.%. In general, the nonionic and anionic surfactants of the surfactant system may be chosen from the surfactants described "Surface Active Agents" Vol. 1, by Schwartz & Perry, Interscience 1949, Vol. 2 by Schwartz, Perry & Berch, Interscience 1958, in the current edition of "McCutcheon ' s Emulsifiers and Detergents" published by Manufacturing Confectioners Company or in "Tenside-Taschenbuch" , H. Stache, 2nd Edn., Carl Hauser Verlag, 1981. Preferably the surfactants used are saturated. Suitable nonionic detergent compounds which may be used include, in particular, the reaction products of compounds having a hydrophobic group and a reactive hydrogen atom, for example, aliphatic alcohols, acids, amides or alkyl phenols with alkylene oxides, especially ethylene oxide either alone or with propylene oxide. Specific nonionic detergent compounds are Ce to C22 alkyl phenol-ethylene oxide condensates, generally 5 to 25 EO, i.e. 5 to 25 units of ethylene oxide per molecule, and the condensation products of aliphatic Cs to Cis primary or secondary linear or branched alcohols with ethylene oxide, generally 5 to 40 EO.
Suitable anionic detergent compounds which may be used are usually water-soluble alkali metal salts of organic sulphates and sulphonates having alkyl radicals containing from about 8 to about 22 carbon atoms, the term alkyl being used to include the alkyl portion of higher acyl radicals. Examples of suitable synthetic anionic detergent compounds are sodium and potassium alkyl sulphates, especially those obtained by sulphating higher Cs to Cis alcohols, produced for example from tallow or coconut oil, sodium and potassium alkyl Cg to C20 benzene sulphonates, particularly sodium linear secondary alkyl Cio to Ci5 benzene sulphonates; and sodium alkyl glyceryl ether sulphates, especially those ethers of the higher alcohols derived from tallow or coconut oil and synthetic alcohols derived from petroleum. The preferred anionic detergent compounds are sodium Cu to Ci5 alkyl benzene sulphonates and sodium C12 to Cis alkyl sulphates. Also applicable are surfactants such as those described in EP-A-328 177 (Unilever) , which show resistance to salting-out, the alkyl polyglycoside surfactants described in EP-A-070 074, and alkyl monoglycosides .
Preferred surfactant systems are mixtures of anionic with nonionic detergent active materials, in particular the groups and examples of anionic and nonionic surfactants pointed out in EP-A-346 995 (Unilever) . Especially preferred is surfactant system that is a mixture of an alkali metal salt of a C±β to Cis primary alcohol sulphate together with a C12 to Ci5 primary alcohol 3 to 7 EO ethoxylate .
The nonionic detergent is preferably present in amounts greater than 10%, e.g. 25 to 90 wt . % of the surfactant system. Anionic surfactants can be present for example in amounts in the range from about 5 wt . % to about 40 wt . % of the surfactant system.
BUILDERS OR COMPLEXING AGENTS
The composition comprises from 1 to 50 wt . % of a builder.
Builder materials may be selected from 1) calcium sequestrant materials, 2) precipitating materials, 3) calcium ion-exchange materials and 4) mixtures thereof.
It is preferred that when an insoluble inorganic builder, e.g., zeolite, is used the size is in the range 0.1 to 10 microns (as measured by The Mastersizer 2000 particle size analyzer using laser diffraction ex Malvern™) . Examples of calcium sequestrant builder materials include alkali metal polyphosphates, such as sodium tripolyphosphate and organic sequestrants, such as ethylene diamine tetra- acetic acid.
Examples of precipitating builder materials include sodium orthophosphate and sodium carbonate.
Examples of calcium ion-exchange builder materials include the various types of water-insoluble crystalline or amorphous aluminosilicates, of which zeolites are the best known representatives, e.g. zeolite A, zeolite B (also known as zeolite P) , zeolite C, zeolite X, zeolite Y and also the zeolite P-type as described in EP-A-O, 384, 070.
The composition may also contain 0-50 wt . % of a builder or complexing agent such as ethylenediaminetetraacetic acid, diethylenetriamine-pentaacetic acid, alkyl- or alkenylsuccinic acid, nitrilotriacetic acid or the other builders mentioned below. Many builders are also bleach- stabilising agents by virtue of their ability to complex metal ions.
Zeolite and carbonate (carbonate (including bicarbonate and sesquicarbonate) are preferred builders.
The composition may contain as builder a crystalline aluminosilicate, preferably an alkali metal aluminosilicate, more preferably a sodium aluminosilicate. This is typically present at a level of less than 15 wt . % . Aluminosilicates are materials having the general formula: 0 . 8 - 1 . 5 M2O . Al2O3 . 0 . 8 - 6 S iO2

The preferred sodium aluminosilicates contain 1.5-3.5 SiO2 units in the formula above. They can be prepared readily by reaction between sodium silicate and sodium aluminate, as amply described in the literature. The ratio of surfactants to aluminosilicate (where present) is preferably greater than 5:2, more preferably greater than 3:1.
Alternatively, or additionally to the aluminosilicate builders, phosphate builders may be used. In this art the term λphosphate' embraces diphosphate, triphosphate, and phosphonate species.

Experimental
Example 1
Three knitted cotton fabric swatches (20 by 20 cm) dyed with Vat Blue 4 were washed in a compartment of a Quickwash Plus ™ fabric testing system (SDL international) . In a separate compartment equivalent knitted cotton swatches were placed, but these were dyes with Reactive Orange 16. The machine was filled with 3.5 litres of 26° French Hard water and 24.5 g of Persil Colour Powder (ex UK) a Las/Non-ionic surfactant powder built with zeolite and carbonate. To this was added 0.5 g of antifoam. The wash took 15 minutes, and following this the machine was drained, spun, and then three 90 second rinses performed, draining and spinning after each. Following the wash the fabric was tumble dried. The procedure was repeated 5 times. The whole experiment was then repeated but with the addition of lg/L of various additives .
Following the washes the reflectances of the VAT Blue cloths at 430nm and the Reactive Orange cloths at 650nm were measured on a Murakami Goniospectrophotometer with an incident angle of 65° and a measurement angle of 55°. The reflectance of the new cloths was 27.20 for the Vat Blue and 65.13 for the reactive Orange. The reflectance was compare to the reflectance of new unwashed fabric, and expressed as ΔR = I R (new) - R (washed) | . The ΔR (powder control) for Vat Blue was 6.06 and for Reactive Orange was 5.36. In the results shown in table 1 the average ΔR for the blue and orange cloths is given to 1 decimal place.
Table 1
Glass beads were obtained from Sigmund Lindner and had a Siθ2 content of 72.5%
Sand was obtained from Schlingmeier Quartz sand and had a SiO2 content of 98.9%
Silica-alumino ceramic microsphere particles were obtained from 3M. The Silica-alumino ceramic microsphere examples are comparative, and show the advantage of the Siθ2 particles in comparison to other spherical inorganic particles.
The Siθ2 particles maintain the cloth closer to the new, as indicated by smaller ΔR430 values.
Example 2
Exemplary Granular Laundry Formulations A, B, C, D - I i
Enzyme levels are given as percent pure enzyme. Levels of direct violet 9, solvent violet 13 and Sulfonated Zn Pthalocyanine photobleach are given as pure dye. NI (7EO) refers to R- (OCH2CH2) n0H, where R is an alkyl chain of C12 to C15, and n is 7.
The formulations are prepared by adding direct violet 9, and the Sulfonated Zn Pthalocyanine photobleach into the slurry which is then spray dried. Alternatively, the dyes and photobleach may be added via post-dosed MgSO4 granules.
The solvent violet 13 was dissolved in non-ionic surfactant (7EO) to give a 0.5 wt% solution and granulated onto bentonite clay, to give a granule containing 0.2wt% dye. This was post-dosed to the formulation.
The glass bead (Sigmund Lindner) was added in two ways, by addition to the slurry and by post-dosing. It was noted the bead aided flow of the powder.
