Definitions
- the present invention relates to laundry treatment compositions with increased deposition of the dye to a substrate.
- Garments comprising polyester fibres are ubiquitous. Many garments are white but over the lifetime of these garments the whiteness is dulled reducing the aesthetic value of the garment. There is a need to maintain the white appearance of such garments such that the aesthetic value is retained as long as possible.
- Bleach, fluorescers and shading agents are used in modern wash processes to maintain whiteness.
- the fluorescers and shading agents that are currently available, do not deposit on polyester fibres of garments to a significant degree. All fibres may be subjected to a bleaching process but over time such treatment can lead to the garment taking a yellow hue.
- United States Patent 3,958,928 discloses a liquid dye composition together with methods for its use.
- the dye composition is a mixture of anthraquinone dyes suitable for use with liquid laundry detergents.
- the composition substantially reduces the undesirable fabric staining characteristic of a detergent in which the dye is employed, while still retaining the ability to blue the fabric.
- the composition is a combination of an oil soluble dye such as 1,4-bis(2-ethylhexylamino)-anthraquinone (C.I. Solvent Blue 58) with a water soluble dye such as 1-amino-2-sulfo, 4-(2-sulfo-para toluidino) anthraquinone sodium salt (C.I.
- Acid Blue 145) and/or 1,4-bis(3-sodium sulfonate mesitylidino) anthraquinone C.I. Acid Blue 80
- the dye disclosed has two eight carbon branched substituents. The dye levels disclosed are above 0.0005% of the formulation. Long alkyl chains aid the incorporation of the highly hydrophobic dye in water surfactant compositions. Surprisingly a wide range of disperse and solvent anthraquinone dyes without long alkyl chains are discovered which have much better function as shading dyes from homogeneous (isotropic) liquid laundry or granular formulations.
- USP 6,521,581 discloses the use of anthraquinone dyes in a bi-phase (anisotropic) liquid detergent composition with high levels of coloured inorganic salts.
- DE 2557783 discloses water soluble dyes and also discloses hydrophobic dyes disperse blue 87 and disperse blue 7 at a level of 0.0001 wt%. Neither of these hydrophobic dyes is demonstrated as substantive to textiles.

Examples of suitable synthetic anionic detergent compounds are sodium and potassium alkyl sulphates, especially those obtained by sulphating higher C8 to C18 alcohols, produced for example from tallow or coconut oil, sodium and potassium alkyl C9 to C20 benzene sulphonates, particularly sodium linear secondary alkyl C10 to C15 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 C11 to C15 alkyl benzene sulphonates and sodium C12 to C18 alkyl sulphates. Also applicable are surfactants such as those described in
EP-A-328 177 EP-A-070 074 - 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 - 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% to about 40 wt % of the surfactant system.
- When the present invention is used as a fabric conditioner it needs to contain a cationic compound.
- Most preferred are quaternary ammonium compounds.
- It is advantageous if the quaternary ammonium compound is a quaternary ammonium compound having at least one C12 to C22 alkyl chain.
- It is preferred if the quaternary ammonium compound has the following formula:
- A second class of materials for use with the present invention are the quaternary ammonium of the above structure in which R1 and R2 are independently selected from C12 to C22 alkyl or alkenyl chain; R3 and R4 are independently selected from C1 to C4 alkyl chains and X- is a compatible anion.
- A detergent composition according to claim 1 in which the ratio of (ii) cationic material to (iv) anionic surfactant is at least 2:1.
- Other suitable quaternary ammonium compounds are disclosed in
EP 0 239 910 (Proctor and Gamble). - It is preferred if the ratio of cationic to nonionic surfactant is from 1:100 to 50:50, more preferably 1:50 to 20:50.
- The cationic compound may be present from 0.02 wt % to 20 wt % of the total weight of the composition.
- Preferably the cationic compound may be present from 0.05 wt % to 15 wt %, a more preferred composition range is from 0.2 wt % to 5 wt %, and most preferably the composition range is from 0.4 wt % to 2.5 wt % of the total weight of the composition.
- If the product is a liquid it is preferred if the level of cationic surfactant is from 0.05 wt % to 10 wt % of the total weight of the composition. Preferably the cationic compound may be present from 0.2 wt % to 5 wt %, and most preferably from 0.4 wt % to 2.5 wt % of the total weight of the composition.
- If the product is a solid it is preferred if the level of cationic surfactant is 0.05 wt % to 15 wt % of the total weight of the composition. A more preferred composition range is from 0.2 wt % to 10 wt %, and the most preferred composition range is from 0.9 wt % to 3.0 wt % of the total weight of the composition.
- It is most preferred that the present composition contains less than 0.1 wt % of any coloured inorganic electrolytes such as nickel or cupric sulphate. Most preferably the present composition is devoid of any coloured inorganic electrolytes.
- The laundry treatment composition may comprise bleaching species. The bleaching species, for example, may selected from perborate and percarbonate. These peroxyl species may be further enhanced by the use of an activator, for example, TAED or SNOBS. Alternatively or in addition to, a transition metal catalyst may used with the peroxyl species. A transition metal catalyst may also be used in the absence of peroxyl species where the bleaching is termed to be via atmospheric oxygen, see, for example
WO02/48301 - The laundry treatment composition comprises a fluorescent agent (optical brightener). We have found that the presence of a fluorescent agent enhances the deposition of the dye. Fluorescent agents are well known and many such fluorescent agents are available commercially. Usually, these fluorescent agents are supplied and used in the form of their alkali metal salts, for example, the sodium salts. The total amount of the fluorescent agent or agents used in laundry treatment composition is from 0.005 to 2 wt %, more preferably 0.01 to 0.1 wt %. Preferred fluorescers are: sodium 2 (4-styryl-3-sulfophenyl)-2H-napthol[1,2-d]triazole, disodium 4,4'-bis{[(4-amilino-6-(N methyl-N-2 hydroxyethyl) amino 1,3,5-triazin-2-yl)]amino}stilbene-2-2'disulfonate, disodium 4,4'-bis{[(4-anilino-6-morpholino-1,3,5-triazin-2-yl)]amino} stilbene-2-2' disulfonate, and disodium 4,4'-bis(2-sulfostyryl)biphenyl.
- Preferably the laundry treatment composition comprises a perfume. The perfume is preferably in the range from 0.001 to 3 wt %, most preferably 0.1 to 1 wt %. Many suitable examples of perfumes are provided in the CTFA (Cosmetic, Toiletry and Fragrance Association) 1992 International Buyers Guide, published by CFTA Publications and OPD 1993 Chemicals Buyers Directory 80th Annual Edition, published by Schnell Publishing Co.
- 65:35 pieces of woven polyester-cotton was washed in water containing 0.5 g/L SDS surfactant and 0.5g/L NaCl for 30 minutes at room temperature (20°C). To this was added varying levels of the fluorescers Tinopal CBS-X (ex Ciba Speciality Chemicals, Basel) and solvent violet 13. The solvent violet 13 was added with vigorous agitation from a 50 ppm ethanol stock solution. After the wash the clothes were dried and their reflectance spectra recorded with UV light excluded from below 420nm. The level of solvent violet 13 deposited to the cloth may be conveniently measured via the reflectance at 580nm.
- The results are shown in the table below, where the K/S value at 530 nm is given.
- Kits = (1-R)2/(2R) and is proportional to the dye loading on the cloth.
- As expected the CBS-X does not significantly change the baseline value of K/S(580) as UV light is excluded and the molecules does not absorb or emit at this wavelength.
ppb SV13 in wash solution ppm CBS-X in wash solution 0 0.5 1.0 2.0 0 0.0067 0.0064 0.0064 0.0068 200 0.0151 0.0157 0.0163 0.0174 - The adsorption of solvent violet 13 to the cloth is clearly seen by the increase in K/S(580). Surprisingly the adsorption increases as the CBS-X level is increased, so that there is more dye on the cloth. This is completely unexpected as CBS-X deposits to the cotton fibres and solvent violet 13 to the polyester fibres in the cloth.
- The fluorescer makes the deposition of solvent violet 13 more efficient.
