る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the use of a suspension in water containing a peroxycarboxylic acid derived from a dicarboxylic acid containing 8 to 13 carbon atoms as a pourable bleaching composition. Such a use is known from British Patent No. 1535804. It describes a liquid bleaching composition having a viscosity of 200 to 100,000 mPa.s and containing a peroxide, a thickener and water. They are suitable for use in washing machines and automatic clothes dryers.

布という上記利点は部分的になくなつてしまう。The advantage of using a liquid bleaching composition over a solid bleaching composition is that there is no costly forming step in its preparation such as drying and granulation, and that the fabric to be treated is bleached quickly and uniformly. Therefore, high local bleach concentrations are to be satisfactorily avoided. British Patent No. 1535804
No. bleaching compositions have the disadvantage that they are physically unstable, at least as long as they can be poured (see below) and are difficult to disperse or homogenize after long term storage. This results in a phase-separated product with a thick bottom layer, which partly eliminates the above-mentioned advantage of uniform distribution on the treated fabric.
本漂白組成物は、この欠点を示さない。The bleaching composition does not exhibit this drawback.

It is known to carry the risk of explosion, shock and abrasion.
However, when spillage and drying of properly selected suspensions of the invention occur, solid peroxide particles are formed with a coating such that they are less sensitive. The pourable composition as disclosed in GB 1535804 is not so protected. The amount of thickener required for this composition is low, and when spilled and dried, poorly desensitized solid particles are formed. Experiments have found that this drawback cannot be eliminated by adding known desensitizers to the suspension. Because the characteristics of these suspensions are:
It is rather worse.

された。Suspensions of the present invention containing alkali metal peroxycarboxylic acids and alkylbenzene sulfonic acids are described in US Pat.
It must be mentioned that it is disclosed in the specification of the 573 specification. However, this patent specification relates to a solid granular bleaching composition, the suspension of which is used for the preparation of a solid composition by drying. This is described in the introductory part of the above U.S. patent specification (column 1, lines 17-20), i.e. liquid bleaching compositions containing a peroxyacid material as the active bleaching agent have a long shelf life. It is clear from the statement that the bleaching effect tends to decrease. Therefore, U.S. Pat. No. 41
No 26573 specification contemplates the present suspension as a bleaching composition. If the peroxycarboxylic acid is finely dispersed in water, the degree of decomposition during storage is great.
Experiments have also found that such decomposition occurs in the case of a large number of anionic and nonionic emulsifiers. However, it has been found that the presence of an alkali metal salt of alkylbenzene sulfonic acid as an emulsifier has no or little adverse effect on the active oxygen content of the composition.

Such peroxycarboxylic acids are insoluble or sparingly soluble in water (solubility in water at 20 ° C. less than 1% by weight). Mixtures of these acids may also be used. It is preferred that the composition of the present invention comprises a diperoxydicarboxylic acid such as 1,12-diperoxidedecanedioic acid, 1,13-diperoxytridecanedioic acid or suitable mixtures thereof.
The production of these acids is carried out in a known manner by reacting the corresponding dicarboxylic acid with hydrogen peroxide in the presence of sulfuric acid.

It contains from ~ 15, more preferably from 11 to 13 carbon atoms. Examples of these alkylbenzene sulfonates include sodium undecylbenzene sulfonate, sodium dodecylbenzene sulfonate, and sodium tridecyl benzene sulfonate. Also, a mixture of these sulfonates may be used. It is preferred that the composition of the present invention comprises sodium dodecylbenzene sulfonate. The alkyl metal salt of alkylbenzene sulfonic acid should be used in an amount such that the composition is pourable and physically stable, generally the composition is 0.5 to 15 wt% based on the weight of the composition. %, Preferably 2-10% by weight, will contain the alkali metal salt of an alkylbenzene sulfonic acid. Use of less than 0.5% by weight results in a composition with insufficient physical stability; use of more than 15% by weight results in a viscous composition that can no longer be poured.

重量％（組成物重量に対して）の無機塩を含む。Alkali metal salts of alkylbenzene sulphonic acids, which are generally used as emulsifiers, are so-called industrial products, which contain inorganic salts such as sodium sulphate as impurities. While these industrial products can be used very well to make the compositions of the present invention, a preferred embodiment consists in the addition of certain inorganic salts. It has been found that sodium sulphate potassium sulphate or mixtures thereof have a favorable effect on the physical stability of the composition.
That is, if any precipitation appears with the industrial emulsifier alone, it can be completely stopped by the additional use of the above inorganic salts. It has also been found that when the above inorganic salts are used, a composition with the same properties can be made with less emulsifier than if they were not used. This last-mentioned embodiment is preferred in practice because the price of the inorganic salt is considerably lower than that of the emulsifier.
The amount of inorganic salt used depends in part on the amount of inorganic salt as an impurity originating from the emulsifier and must be such that the bleaching composition is pourable and physically stable. Generally, the bleaching composition of the present invention contains 0.01 to 20% by weight, preferably 2 to 10% by weight of the inorganic salt derived from the emulsifier.
Includes wt% (based on composition weight) of inorganic salts.

つ。The composition of the present invention comprises an acidic mixture of water, alkylbenzene sulphonate and other additives (preferably pH 3.5-4.5).
Can be prepared by adding peroxycarboxylic acid with stirring. The peroxycarboxylic acid can be used in powder form (primary particle size 1-100μ) or in the form of a wet filter cake as obtained in the preparation of the peroxycarboxylic acid from the corresponding dicarboxylic acid and hydrogen peroxide. . If necessary, the pH of the composition can be finally set to a particular desired value, which must be in the acidic range, for example sodium hydroxide or aqueous hydrochloric acid can be used. It is preferred that the pH is less than 5. Higher numbers have a negative effect on the chemical stability of the composition. However, pH lower than 2
Should also be avoided. The insufficiently high final pH obtained by diluting such a composition with water will corrode the metal parts of the washing machine in which it is used. Particularly preferably, the composition has a pH of 3.5 to 4.5, especially 3.9 to 4.1.

きることが判つている。 The results in the table show that emulsifiers other than alkylbenzene sulfonates have a negative effect on the chemical stability of peroxycarboxylic acid-containing suspensions. Note that Suspension 1 is not a composition according to the present invention. It contains about 30% emulsifier and has a viscosity of 1975 mPa.s. It has been found that the effect of emulsifiers on the chemical stability of peroxycarboxylic acid compositions can be well confirmed when they are used at relatively high concentrations.
