Description
LAUNDRY TREATMENT COMPOSITIONS
The present invention relates to laundry treatment compositions which comprise a dye.
Reactive dyes are coloured compounds with one or more functional groups capable of forming a covalent bond with a suitable substrate, generally cotton or other cellulosic fibres. Typical reactive groups of the reactive dyes are monochlorotriazinyl, monofluorotrazinyl and 2- sulfooxyethylsulfonyl. Typical chromophores of the reactive dyes are azo, anthraquinone, phthalocyanine, formazan and triphendioaxazine.
The reactive dyes have specific functional groups that can = undergo addition or substitution reactions with -OH, -SH and -NH2 groups present in textile fibers. A consequence of the nature of these specific functional groups is that reactive dyes can cause irritation/sensitization of the respiratory tract and skin. There is also evidence that they give rise to contact dermatitis, allergic conjunctivis, rhinitis, occupational asthma and other allergic reactions.
We have found that hydrolysed reactive dyes may be used to impart shading to textiles whilst reducing the risk of irritation/sensitization of the respiratory tract and skin in comparison to reactive dyes.
2 =
In the presence of water and high pH the reactive groups of reactive dyes are hydrolysed. We have found that the hydrolysed reactive dye is also substantive to cotton under normal wash conditions. oo | | Co
In one aspect the present invention provides a laundry treatment composition comprising between 0.0001 to 0.1 wt % "of a hydrolysed reactive dye and between 2 to 60 wt % of a surfactant. :
In another aspect the present invention provides a method of ~ ‘treating a textile, the method comprising the steps of: (i) treating a textile with an aqueous solution of a hydrolysed reactive dye, the aqueous solution comprising from 10 ppb to 1 ppm of the hydrolysed reactive dye and from 0.2 g/L to 3 © g/L of a surfactant; and, (ii) rinsing and drying the textile. Most preferably the hydrolysed reactive dye is at a concentration in the range from 100 ppb to 500 ppb. The present invention also extends to the aqueous solution used in the method.
A “unit dose” as used herein is a particular amount of the laundry treatment composition used for a type of wash, ‘conditioning or requisite treatment step. The unit dose may be in the form of a defined volume of powder, granules or tablet or unit dose detergent liquid.
The reactive dyes may be considered to be made up of a chromophore which is linked to an anchoring moiety, The chromophore may be linked directly to the anchor or via a bridging group. The chromophore serves to provide ‘a colour and the anchor to bind to a textile substrate.
A marked advantage of reactive dyes over direct dyes is that their chemical structure is much simpler, their absorption oo bands are narrower and the dyeing/shading are brighter; = . industrial Dyes, K. Hunger ed. Wiley-VCH 2003 ISBN 3-527- 30426~6. However, mammalian contact with reactive dyes results in irritation and/or sensitisation of the respiratory tract and/or skin. In addition, wash conditions are not ideal for deposition of dyes because the efficiency of deposition is low. oo “With regard to reducing irritation and/or sensitisation, it 15° is preferred that each individual anchor group of each reactive dyes is hydrolysed such that the most reactive group (s) of anchor groups of the dye is/are hydrolysed. In this regard, the term hydrolysed reactive dye encompasses both fully and partially hydrolysed reactive dyes. : The reactive dye may have more -than one anchor. If the dye
Bg has more than one anchor, then each and every anchor, that contributes to irritation and/or sensitisation, needs to be hydrolysed to the extent discussed above.
The dyes used in the present invention. comprise a chromophore and an anchor that are covalenly bound and may be represented in the following manner: Chromophore-anchor.

Example 1: Deposition on cotton
To determine the substantivity of a dye the following : experiment was performed. A 0.1 wt $% solution of the reactive dye was created in a pH = 10 buffer and was left for four days in the dark at room temperature to allow the reactive groups to hydrolyse. A stock solution of 1.5 g/L of a base washing powder in water was created. The washing : powder contained 18 % NaLAS, 73 % salts (silicate, sodium tri-poly-phosphate, sulphate, carbonate), 3 % minors including perborate, fluorescer and enzymes, remainder impurities and water. The solution was divided into 60 ml
- 12 - oo ‘aliquots and hydrolysed reactive dye added to this to give 2 solution of optical density of approximately one (5 cm pathlength) at the maximum absorption of the dye in the visible lengths, 400 to 700nm. The optical density was measured using a UV-visible spectrometer. One piece of bleached, non-mercerised, non-fluorscent woven non- mercerised cotton cloth (ex Phoenic Calico) weighing 1.3 g was placed in the solution at room temperature (20 °C). + This cloth represents a slightly yellow cotton.
