Description

Treatment compositions for washing clothes.

Technical field

The present invention relates to compositions of treatment for washing clothes comprising a Colorant.

Background of the invention

Reactive dyes are compounds colored with one or more functional groups that can form a covalent bond with a suitable substrate, usually fibers of cotton or other cellulosic fibers. The typical reactive groups of The reactive dyes are monochlorotriazinyl, monofluorotriazinyl and 2-sulfooxyethylsulfonyl. Typical chromophores of reactive dyes are azo, anthraquinone, phthalocyanine, formazan and trifendioxazine.

Reactive dyes have groups specific functions that may experience reactions of addition or substitution with -OH, -SH and -NH2 groups present in the textile fibers. A consequence of the nature of these groups specific functional is that reactive dyes can cause irritation / sensitization of the respiratory tract and skin. There is also evidence that they produce contact dermatitis, allergic conjunctivitis, rhinitis, professional asthma and others allergic reactions.

Summary of the invention

It has been found that reactive dyes hydrolysates can be used to impart coloration to materials  textiles while reducing the risk of irritation / sensitization of the airways and skin compared to reactive dyes.

In the presence of water and high pH, the reactive groups of reactive dyes. It has been found that the hydrolyzed reactive dye is also a noun for the cotton under normal washing conditions.

In one aspect, the present invention provides a treatment composition for laundry washing comprising between 0.0001% by weight and 0.1% by weight of a reactive dye hydrolyzed and between 2% by weight and 60% by weight of a surfactant

In another aspect, the present invention provides a process for treating a textile material, the procedure comprising the steps of: (i) treating a material textile with an aqueous solution of a reactive dye hydrolyzed, the aqueous solution comprising from 10 ppb to 1 ppm of the hydrolyzed reactive dye and from 0.2 g / l to 3 g / l of a surfactant; and, (ii) rinse and dry the textile material. The more preferably, the hydrolyzed reactive dye is at a concentration in the range from 100 ppb to 500 ppb. The The present invention also extends to the aqueous solution used. in the procedure

A "unit dose" as used in the This document is a particular amount of the composition of treatment for washing clothes used for a type of washing, of conditioning or necessary treatment stage. The dose unit can be in the form of a defined volume of powders, granules or tablets or dose detergent liquid unitary.

Detailed description of the invention

Reactive dyes can be considered they are composed of a chromophore that is attached to a rest of anchorage. The chromophore can be attached directly to the anchor or by a bridge group. The chromophore serves to provide a color and anchor to join a textile substrate.

A notable advantage of reactive dyes over direct dyes is that their chemical structure is much simpler, their absorption bands are narrower and the staining / coloring is stronger; Industrial Dyes, K. Hunger ed. Wiley-VCH 2003 ISBN 3-527- 30426-6. However, contact of mammals with reactive dyes results in irritation and / or sensitization of the respiratory tract and / or the skin. In addition, the washing conditions are not ideal for the deposition of dyes since the effectiveness of the deposition is
low.

With respect to the reduction of irritation and / or sensitization, it is preferred that each individual anchor group of each reactive dye is hydrolyzed so that the most reactive group (s) of the anchor groups of the dye is hydrolyzed (n). In this regard, the expression hydrolyzed reactive dye encompasses reactive dyes hydrolyzed both completely and partially.

The reactive dye may have more than one anchorage. If the dye has more than one anchor, then it you need each of the anchors that contributes to irritation and / or sensitization is hydrolyzed to the extent treated previously.

The dyes used in the present invention they comprise a chromophore and an anchor that are covalently attached  and can be represented as follows: chromophore-anchor. The junction between the chromophore and a anchoring is preferably provided by -NH-CO-, -NH-, NHCO-CH2CH2-, -NH-CO-, or -N = N-.

It is preferred that, when dissolved in water a "unit dose" of the treatment composition for the laundry, the ionic strength of the treatment composition for the resulting aqueous laundry wash be between 0.001 and 0.5, plus preferably between 0.02 and 0.2.

Examples

Example one

Cotton deposition

To determine the substantivity of a dye The following experiment was performed. A 0.1% solution was created by weight of the reactive dye in a buffer of pH = 10 and left in the darkness for four days at room temperature to leave that the reactive groups be hydrolyzed. A solution was created 1.5 g / l mother of a basic washing powder in water. The dust of wash contained 18% NaLAS, 73% salts (silicate, sodium tripolyphosphate, sulfate, carbonate), 3% of components minorities that include perborate, fluorescent agent and Enzymes, the rest impurities and water. The solution was divided into 60 ml aliquots and the hydrolyzed reactive dye was added to this giving an optical density solution of approximately one (optical path length of 5 cm) at maximum absorption of dye in the visible wavelengths, from 400 to 700 nm. The optical density was measured using a spectrometer of UV-visible A piece of cotton cloth was placed woven, non-fluorescent, non-mercerized, bleached (from Phoenic Calico) weighing 1.3 g in the solution at room temperature (20 ° C). This fabric represents a slightly yellow cotton. Be let the cloth soak for 45 minutes, then stir the solution for 10 min., rinsed and dried. After this I know re-measured the optical density of the solution and calculated the amount of dye absorbed by the fabric.
