Abstract

Improved fabric washing detergent composition especially but not exclusively designed for washing mixed coloured fabrics comprising from 0.5 to 25 % by weight of a peracid compound selected from the group consisting of organic peracids, peracid salts and peracid precursors which generate peracids by hydrolysis or perhydrolysis, and from 0.002 to 2.5 % by weight of copper, in the absence or substantial absence of a powerful sequestrant which complexes strongly with copper. The composition is effective in minimizing dye transfer but is non-effective or substantially non-effective with respect to direct fabric dye or stain bleaching.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a detergent composition particularly suitable for washing colored fabrics or mixed colored fabrics having colored and white areas. However, the present composition is by no means limited to the washing of colored fabrics or mixed-colored fabrics as described above, and can of course be used as a detergent for other items.

Traditionally, two types of textile cleaning compositions have been used, namely:

(1) No yellow! Detergent composition for white-type colored fabrics: This detergent composition does not adversely affect textile dyes and can be safely used, but it does not have the effect of effectively suppressing the tendency of dye release seen in some colored fabrics. Therefore, the dye of the colored fabric is liberated and enters the washing liquid, and this dye is disadvantageously transferred to and adheres to other fabrics being washed.

(2) Colored textile detergent compositions containing whitening agents: This has the ability to inhibit the transfer of dyes as described above, but at the same time it also has the ability to whiten and lighten the color of textiles. There are 5 things.

Therefore, in the past, there was no way to effectively solve the dye transfer problem other than separating the fabrics to be washed into dark-colored fabrics and light-colored fabrics and washing them separately.

As colored clothing and fabrics, especially multicolored ones, have become popular in IA, the above-mentioned dye transfer problem has become an increasingly serious problem. Various proposals have been made to solve this problem, but so far none have been particularly successful.

For example, British Patent Application (GB-A) No. 1,368.40
[Specification 7+7 of No. J discloses a dye transfer inhibitor composition containing a peroxide such as an organic peracid and a relatively complex aldehyde or ketone compound as a distillation activator. is 1. The composition has some drawbacks, namely that it requires relatively expensive organic compounds (i.e. complex aldehyde or ketone compounds);
Moreover, the effect is not very good at all. Other compositions of beam transfer inhibitors are also known. European Patent No. M [1 #: 0024368] discloses a composition containing an organic peracid precursor (precursor) and a bromide ion-based activator. ing. The main disadvantage of these compositions is that the fabric whitening effect is so strong that the color fades in colored fabrics.

European Patent Application No. 0 058 444 discloses dye transfer textile detergent compositions for use at relatively low temperatures, which contain as an essential component an organic peracid or an organic peracid precursor. It contains a water-soluble iodide-type salt. Although this iodide is a catalyst, it has some drawbacks: (1) there is a risk of undesirable coloration due to iodine formation, and (2) there is a risk of directly bleaching the dyes in the fabric. There is also.

The purpose of the present invention is to use a fabric that can be used when washing 1 f, ffi, or various fabrics of two or more colors (including washing of colored fabrics and white fabrics together). The object of the present invention is to provide a novel detergent composition for textiles which does not have the above-mentioned disadvantages.

Another object of the present invention is to provide effective FC bleaching of dyes in solution, i.e. to minimize said dye transfer, and without or substantially no direct bleaching of dyes in textiles. An object of the present invention is to provide a detergent composition having the following characteristics:

These and other objects are the use of a detergent composition characterized in that it contains a peracid and a copper catalyst, but does not contain strong sequestrants that react strongly with copper to form complexes. It was discovered this time that it can be achieved by
This will become clear from the following description.

As a result of the inventor's research, the following was discovered.

The transition metal ion has a catalytic effect that enhances the action of the oxygen bleach on the dye in the solution. For example, hydrogen peroxide or hydrogen peroxide ducts or inorganic persalts/
Bleach activator compositions, or peracids themselves, etc. can all be activated with steel ions. Furthermore, bleach compositions containing a copper catalyst and a peracid may be more effective than bleach compositions containing a copper catalyst and a hydrogen peroxide-based compound (e.g., sodium perborate). discovered.

Experiments on the catalytic effect of transition metal ions on the bleaching effect of peracetic acid on direct dyes in solution were conducted under the following experimental conditions.

Conditions: “Direct Red 81” which is a surface dye.
A solution of J (dye concentration 0.002% w/w) in busy acetic acid (
4,6×10='mol/13) was added and the dye concentration was measured at the wavelength of the layer's highest absorbance. Various transition metal compounds (Cu5O, MnSO4, CoCIV2, FeC
A3, NiSO4, T1(so,)2], the above experiment was repeated many times. This experiment was conducted at pH 9 and 40°C.

The results of this experiment are shown in Table 1. In addition, in the dye concentration measurement operation described above, at the beginning of each experiment, λmax is set after the addition of the transition metal compound, but before the addition of the
(490 ri 10 nm) and maximum absorbance (=1
00 dye) was determined as d111.

It is only possible to carry out a combination using a transition metal ion that can easily carry out a one-electron Donks reaction that results in the formation of
However, recognizing this is 611! This is extremely important in research on white mechanisms.

As shown in Table 1, in addition to copper, cobalt is the only transition metal that exhibits sufficient catalytic activity during dye bleaching with peracetic acid; other transition metals include: All are inert, including chromium and zinc.

Although the inventor is not bound by any theory,
It is generally thought that the dye bleaching reaction using an oxidizing brightener can proceed through the following two reaction routes.

Route A Mn″-+-n-+Mn”D-+DMn”Bl-+ g
el oxidation # h, Ta dye P) (+l) Route B Oxidized dye where M is metal, D is dye 1. B(+ represents (9jH white county j).

The term "radical" used for 1 refers to a radical that can be subjected to -electron reactions.This reactive radical reacts with dyes, but the exact nature of this radical has not yet been determined.

The transition metal ion reacts with the peroxide-based compound according to the reaction formula shown in reaction route B, decomposing the latter and producing radicals, and that this radical is highly oxidized. Transition metals that are as effective as copper in terms of dye transfer prevention f1 action are all (), (L, It was discovered that

As an explanation for the above phenomenon, transition metal ions are
A possible reaction mechanism is to strongly react with various dyes to form a complex according to the reaction formula described in . This reaction mechanism is not well known for 4f'V1. The reaction of transition metals with whitening agents along the above reaction path only occurs after the metals have reacted with the dye, and this appears to actually only occur in the case of copper. In addition, the complex formation reaction between transition metals and dyes promotes dye bleaching.
It seems more or less certain. This is because the decomposition reaction of the bleaching agent in the presence of a metal catalyst can occur in the vicinity of the dye in the dye-metal-bleaching agent complex. The fact that copper ions form complexes more readily than other transition metal ions may explain why copper is generally the most useful transition metal when bleaching dyes in solution. It is considered one. The cupric ion, which is the smallest divalent transition metal ion and has the highest charge density, most readily forms stable complexes.

Complexes of cobalt (Ill) and chromium (11) with dyes are also very stable, but unlike copper molecules, they are mechanically inert and cobalt is present in the chemical structure of the dye. In order to introduce (■) and chromium (Ill), it is necessary to carry out the reaction under extremely harsh reaction conditions.

In fact, 'i1f] Haru) II white digestible metal molecule '-/
+j'' is also not a strong decomposer. Cobalt is much more powerful in this regard, and when cobalt is used, oxygen-based 41゛ (free radicals from whitening agents or) 11-radical intermediates Experimental results have shown that cobalt is less effective than copper in bleaching dyes, but this is due to the radicals formed when cobalt is used. On the other hand, in the case of copper, the radicals occur near the dye molecules, so cobalt is more effective at dye bleaching than copper. It seems likely.

Manganese is a very useful catalyst in the case of color bleaching,
Manganese is known to be particularly useful in bleaching with hydrogen peroxide bleach in the presence of carbonates, but manganese has also been found to be less effective for the purpose of inhibiting dye transfer. Served.

Experiments have also shown that under practical working conditions manganese interferes with the said catalytic action of copper and that it is therefore preferable to avoid the presence of manganese when carrying out the process of the invention; Ta.

In addition, various experiments were conducted to investigate whether strong metal-dye complex forming ability is one of the essential conditions for copper to exhibit good catalytic activity in dye bleaching in solution. . UV/visible light spectrum experiments confirmed that the dyes ``C Ac1d Reci 81'' and ``C Ac1d Orange 7'' form complexes with copper. However, 1C Ac1d Orange 5, which is an A-do dye that does not have an ortho-hydroxyl group,
When copper sulfate was added to 2", the UV/city spectra changed only slightly, suggesting that the binding force between this dye and copper was very weak. However.

It was confirmed that when copper was added to a solution containing this dye and sodium monopersulfate (one layer of persulfate), the bleaching rate of the dye increased steadily; The dye bleaching rate is similar to that of Saehaku, a dye with strong forming power.

When the complex formation site (θ1tθ) of bis-ortho-ortho-dihydroxya is blocked with chromium (chromium is 'CI Ac1d Blue 16
1" activates the dye dJ white reaction [7 is not a metal], and although the addition of copper alone to this dye hardly changes the visible spectrum, the effect of monopersulfate bleach The dye whitening rate increases considerably when copper is added in the presence of copper.Thus, as a result of these experiments, the complexing power of copper with respect to dyes is significantly higher than that required for dye bleaching reactions in the presence of copper catalysts. It turned out that this was not a condition.

Therefore, copper exhibits the above-mentioned catalytic action even when the complexing power of this metal with the dye is weak or absent. However, the strong complexing power of copper towards dyes under washing operating conditions has been found as a general fact by comparison with other transition metal ions. This is considered to be a contribution.

There is much evidence that dye whitening in the presence of copper catalysts is closely related to the decomposition of the whitening agent in solution. An increase in copper concentration generally results in an increase in dye whitening rate and bleach degradation rate. It has been found that peroxide decomposition reactions in the presence of transition metal catalysts often include an induction period, which can be shortened by increasing the amount of copper ions present. In many experiments on dye whitening in the presence of copper catalysts, it has indeed been observed that the induction period can be shortened by increasing the copper ion concentration. Although shortening the induction period in this case is accompanied by an increase in the rate of decomposition of the bleach, acceleration of dye marking to avoid dye transfer can be achieved by the following procedure.

Increasing the concentration of (alnW white liquor and copper fil ions, and further increasing the production rate of C radicals by the following means etc., i.e. (bl #(increasing P[I of the white liquor, and (cl.
Adding a suitable reducing agent, such as perboric acid which can generate hydrogen peroxide in solution; Adding hydrogen peroxide in the form of a solid hydrogen peroxide adduct such as IIium or sodium percarbonate.

In addition, various peracids, namely zoperinphthalic acid (I), monopersulfate (II) and peracetic acid (Ill

Tables 1 and 2 show perborate (IJum) when performing a dye bleaching operation using monopersulfate, diperisophthalic acid, or magnesium monoperphthalate.
Experimental results are presented on the effect of the addition of .

It has been found that, in general, the addition of perborate significantly reduces the amount of dye transfer. It has also been found that the optimum molarization of peracid to perborate in this case is about 2:1. Using more perborate than the above values reduces its effectiveness and may even have negative effects in some cases.

Experiments on dye bleaching in solution and dye transfer in a tergotometer were performed according to the following method.

Dye bleaching device in solution This is a spectrophotometer (commercial product; model name: Beckman DBsp) equipped with a fluidic silica cell (IcTn).
It consisted of an electrophotometer (").

Use a water bath to keep the entire liquid sample at a predetermined concentration;
A PH-stand was used for control of -.

This cell is connected to a solution container with a small diameter silicone rubber tube.
Pump for liquid fluid (commercial product; model name: Watson
The solution was circulated using a Marlow flow 1nducer ("Marlow flow 1nducer").To prevent the solution from overflowing into the cell chamber, a return synthesis tube was connected between the cell and the solution container.The silicone rubber tube described above was It was introduced into the cell chamber through a small hole in the lid of the meter.The small amount of light that enters here has no effect on the visible light spectrum.

Fluid Cell (Flow Cell) This fluid silica cell had a path length of 1a. A supply lath tube that reached almost the bottom of the cell was inserted into this stopper. One side of the lath tube was positioned outside the light beam path.

A short drain tube was attached to the top of the cell to allow liquid to flow from the top of the cell through the pump and back into the solution container.

Method A dye solution (stock solution) with a concentration of 0.04% w/v was diluted with distilled water to prepare 250 ml of a 0.004% solution.

The diluted solution was placed in a 600 d beaker placed on a water bath preheated to 40° C. and adjusted to -. This liquid was then passed through the cell at a rate of 40 M/min using a pump. Under these conditions, the liquid flowed within the cell in a good fluid state, and no turbulent flow that could cause foaming occurred.

It was titrated using IJum.

If agents such as electrolytes, surfactants or bleaching aids were to be used, these were added during the preparation of the first dye solution (stock solution).

The whitening rate was compared using the same active oxygen concentration.

To find the wavelength of maximum absorbance, add a wavelength of 70' to the dye solution.
The elements were sequentially irradiated with wavelengths from Onm to 40 D nm. A graph showing the relationship between absorbance (at wavelength λmaX) and concentration (w/v) was then drawn, and the slope was measured.

Measurements were made for various dye solutions and the change in transmittance (c%) was recorded. Therefore, the dye concentration at any time can be calculated using the following equation.

Here, the "slope" is the slope of the line showing the relationship between absorbance and concentration in the graph.

Dye transfer experiment...Test method Various fabrics dyed with various types of dyes were used as samples. 17.5 x 17 in each Kaikai operation
．． A 5α square dyed fabric was used as a sample.

Monitoring of Dye Transfer Reactions Silkened and desized white cotton shirt fabric and white bulky nylon 66 were used as test fabrics to examine dye color transfer. Both fabrics were free of fluorescent dyes. Each of these samples was cut into squares measuring 12.times.12 cIn and, regardless of the type of dye tested, was placed in a wash tub and washed at the same liquor to fabric ratio.

Washing conditions A set of test fabrics was laundered in a tergotometer.

This washing was carried out at a constant temperature (40°C) for 50 minutes. The rotation speed of the washing machine was IQQ rpm.

The temperature of the detergent composition was 0.4% w/v (in hard water at IF 3°) and the liquid to fabric ratio was 50:1. Each set of test fabrics was cooled separately with 600 mJ of water (18° hard water).
Washed with water (rinsed) six times.

How to wash.

Pour 450ml 1V of 18° hard water into Tergobont and
heated to ℃. The previously weighed ingredients were then added. One dyed test fabric and one each of cotton and nylon white test fabrics were placed in the pot and washed for 60 minutes. Rotation speed is 100 rpm
Met.

After washing, each set of test fabrics was removed from each pot and placed separately in 600 cc of cold water (18° hard water). This washing operation was carried out sequentially, ie, each set of test fabrics was washed separately 6 times in 600 cc of cold water (18° hard water).

After washing with water, each test fabric was separated, covered with paper towels to remove excess moisture, and dried in a drying oven at 60°C.

Measurement of dye absorption amount (transfer amount) The reflection height of the test cloth was measured using a spectrophotometer (proprietary product;
ckmann DB GD grating spec
trophotometer J) at the maximum absorption wavelength of the dye. This spectrophotometer was used with a diffuse reflection attachment attached. When measuring the test cloth, barium sulfate was used for standardization of the apparatus and as a reference sample.

As can be seen from the experimental results described above, it is preferred that the compositions of the present invention contain at least 0.002% copper by weight, i.e., about 0.1 ppm or more in solution. The pH of the composition is preferably about 7-11 in a 5y/l solution. , < and the composition comprises a hydrogen peroxide adduct in a molar ratio of the adduct to peracid of about 1:100 to 2:1 - JvI preferably 1:
It is preferable that the content is 25 to 1:1.

For practical reasons, the upper limit of copper concentration is approximately 2.51% (
(based on the total amount of the composition).

In the practice of the present invention, any copper salt can be used as the source of copper, examples of which include copper sulfate, copper carbonate, copper chloride, copper phosphate, and the like.

As mentioned above, sequestration of copper by strong sequestering agents should be minimized, which can promote the detergent/copper reaction and the generation of radicals from the bleach.

On the other hand, excessive decomposition of the bleaching agent during storage of the powder composition must be avoided. To this end, in the present invention, a relatively weak sequestering agent such as a salt of ethylenediaminetetraacetic acid (EDTA) may be present in a very small amount, generally less than VC0.2, preferably about 0.2% by weight. It is less than 1N (based on the total amount of the composition). The allowable amount of sequestering agent added will vary depending on the amount of copper added.

When applying the present invention to detergent compositions containing common types of phosphate virgoos, it is generally necessary to incorporate relatively high amounts of copper in the composition. It is generally preferred that the amount of copper added to such compositions be about 0.02 parts by weight.

From theoretical considerations, the chromophores in the contaminants present on textiles are generally those that have quinonoid properties, which behave very differently from dyes in dye whitening reactions. A variety of dyes such as azo dyes, quinonoid dyes and indigoid dyes can all be bleached in solution by the catalytic action of transition metal ions. The dye can be bleached in solution (by homogeneous reaction), but σ on the fabric

have to move it up. According to the present invention, surprisingly,
It has been found that copper paste added to the washing liquor does not catalyze the bleaching reaction of dyes or colored contaminants on textiles.

Copper in solution reduces the concentration of transferable bleaching agents (whitening agent anion ROO- and especially undissociated RCIOH) in the solution and thereby reduces the concentration of dyes or colors on the fabric (σ) in areas where dyes or colors are present. It seems to have the effect of reducing the amount of bleaching agent transferred to the fabric, thereby reducing the direct bleaching of the fabric.

Although this specification specifically describes the use of peracids in accordance with the present invention, the present invention may also utilize peracid precursor systems. This peracid precursor system is capable of producing organic peracids by hydrolysis or non-hydrolysis in the aqueous phase.

Organic peracids that can be used in the present invention are materials well known in the art. It can be aliphatic or aromatic and has the general formula:

Y-B-C-0-0)] In the above formula, R is an alkylene group having 1 to 16 carbon atoms or an arylene group having 6 to 8 carbon atoms, and Y is hydrogen, nitrogen, or an alkyl group. , represents an aryl group, or a group capable of forming an anion group in an aqueous solution, examples of which include the following.

11? -C-OM: -C-0-OM or -B-OM
1 In the above formula, 11 is hydrogen or a water-soluble salt-forming cation.

Examples of aliphatic peracids include peracetic acid, monoperazelaic acid, zoperazelaic acid, diperadipic acid, ciba-oxydodecanoic acid, decylzotan-zobaroxoinc acid (diper
oxoic acid).

Examples of aromatic peracids include monoperoxyphthalic acid, perbenzoic acid, m-chloro-perbenzoic acid, diperophthalic acid and mixtures thereof.

Examples of persalts include magnesium monoperheptatarate, potassium monopersulfate, and potassium peroxymonophosphate. Mixtures of peracids, which may be mixtures with or without hydrogen peroxide adducts, can also be used advantageously in practice.

A reaction system containing a precursor that can generate peracid in situ will be described. In this case, a mixture of an organic peracid precursor, a so-called "persalt activator" and a persalt of the peroxyhydrate type (e.g. sodium perborate) is subjected to a barhydrolysis operation. Peracids can be produced.Alternatively, peracid precursors can be used that can be hydrolyzed to produce peracids.Therefore, within the scope of the compositions of the invention, various types of peracid precursors can be used. Examples of acid precursors include benzoyl peroxide and sifthaloyl peroxide, both of which are
That is, it is capable of producing perbenzoic acid and monoperoxyphthalic acid, respectively.

Precursors capable of producing peracids by barhydrolysis operations are known in the art, examples include British Patent No. 836
．． 988 and 970,950. Examples of this type of precursor include glycerol benquacetate and tetraacetyl pheasant.

Also, British Patent Nos. 907.356 and 855,735
and 1,246,339, and U.S. Pat. No. 4,128,494 [e.g., N,N,N',N'-tetraacetylethylenediamine (TAED), tetraacetylglycoluril, N,N'-cyacetylacetooxy7methylmalonamide, etc.]; Acyl asoles described in the specification a of Canadian Patent No. 844,481, etc.; Union of South African Patent No. 6
The acylimides described in US Pat. No. 8/6344 and the like and the triazyl cyanurates described in US Pat. No. 3,332,882 and others can also be used.

The amount of peracid compounds in the compositions of the invention is generally 0.5-
25 ir:rt%, preferably 1-15M view%.

The above amounts of peracid compounds are those applicable to organic peracids, persalts and peracid precursors which can produce peracids by hydrolysis or purpuration.

In systems containing an organic peracid precursor and a persalt, it may be advantageous to use a stoichiometric ratio of the organic peracid precursor to the persalt. However, the ratio of peracid to organic precursor can be increased, such as when special scavengers for persalt bleaches, such as catalase, are present.

Preferred persalts are sodium perborate and percarbonate)
IIum.

The amount of precursor capable of producing peracids by barhydrolysis is generally about 0.5-25% by weight, preferably 1-1%.
5. ! Therefore, in this context, the amount of persalt used is generally from 0.5 to 50%, preferably from 0.5 to 60% by weight (based on the weight of the composition).

Therefore, the present invention provides 0.5-25% by weight of peracid or peracid precursor as defined above and 0.00% by weight of copper cation.
Limited only to mixed-color fabrics that are characterized by containing a double layer or higher and not containing or significantly not containing strong metal ion sequestrants that strongly bind with copper to form complexes.

It can be prepared by performing J mist cooling and then dry addition of unstable components (sensitive components), such as solid organic peracid compounds, peracid precursors, inorganic peroxyno-idlate salts, etc.

Additionally, these may be used to improve storage stability or to prevent undesired reactions between the bleaching agent and the copper or other ingredients in the composition from occurring excessively during storage of the composition. Any conventional technique such as milling, granulating, pelletizing, or coating any of the ingredients can be used as desired.
