Field of application of the invention

The invention relates to a solid, phosphate-containing detergent. In particular, the invention relates to a detergent in the low temperature range of 10-30 ° C with bleaching and disinfecting effect.

Characteristic of the known technical solutions

The prior art is characterized by a plurality of detergent formulations having different main properties. The known detergent formulations are suitable for the temperature ranges of 30-9O ⁰ C, but even at a temperature of 2O ⁰ C for the most part still have a certain washing effect.

Bleaching and disinfecting effect are not or only partially pronounced in these detergents.

Only with respect to the bleaching effect has been able to achieve through the use of perborates activator at temperatures below 3O ⁰ C whitening effect, but with significantly impaired washing effect and very poor solubility. German Offenlegungsschrift 1,931,329 lists examples of phosphate-containing detergents which contain sodium dichloroisocyanurate or sodium perborate as the bleaching component.

However, the listed detergents and bleaches are used only in the temperature range of 60-90 ⁰ C.

Furthermore, a process for the preparation of phosphate-containing liquid detergent has been proposed, in which an aqueous solution of Na polyphosphate, sodium metasilicate, carboxymethyl cellulose and chloramine submitted and then mixed with nonionic surfactants. The so-cured liquid detergents act in the temperature range of 20-60 ⁰ C.

Also known is a powdered detergent mixture according to DE-OS 2,456,212, which can be used advantageously in the low temperature range at temperatures of 25 ° C and causes a high degree of whiteness of the laundry. This whiteness is achieved using a precursor of a particular blue dye. This precursor causes during the Waschbohandlung of white laundry a certain blueing and thus an "opical brightening" of the laundry.

Disadvantage of this detergent mixture is that with frequent use of this "optical brightener" a progressive adsorption of the blue component with damaging effect of the fiber and subsequent yellowing occurs, which can only be partially removed by treatment with real bleaches.

In summary, it must be estimated that the previously known detergent formulations only bleach using optical brighteners in the low temperature range, but solubility and washing effect insbv, ondere significantly deteriorated at temperatures below 30 ⁰ C.

Object of the invention

Target dt (invention is to develop a solid detergent, which is characterized especially in the low temperature range of 10-3O ⁰ C dur ^ h high detergency, bleaching and disinfecting effect and does not have the disadvantages of the known Wascbmittelformulierungen.

-2- 299 Explanation of the essence of the invention

The invention has for its object to develop a solid, low-phosphate, bleaching and disinfecting detergent that is particularly suitable in the temperature range of 10-30 ⁰ C for manual and machine washing. The object is achieved in that a detergent combination consisting of:

7-10Ma .-% alkylsulfonate 0.3-0.7 mass% carcass fatty acid 4-8Ma .-% chloramine T (p-toluenesulfonylchloramide-Na-salt trihydrate) 2-4 mass% soda

1-3Ma .-% sodium metasilicate 15-25Ma .-% aluminosilicate 15-25Ma .-% sodium tripolyphosphate 0.2-0.6 mass% aminotrimethanephosphonic acid 1-3Ma .-% urea

0.3-0.5 mass% borax

1, & -2.5Ma .-% carboxymethylcellulose 17-52Ma .-% sodium sulfate 2-4 Ma .-% water

Use finds.

The formulation is superior to all known solid detergent formulations in the temperature range 10-30 ⁰ C with respect to the washing effect, in the bleaching effect equal to those with optical brighteners and simultaneously acts disinfecting by the active chlorine content.

The detergent according to the invention is characterized in that high energetic benefits are achieved when it is used. It is low in phosphates and surfactant-reduced and therefore trendsetting on the environment.

The effectiveness of the detergent furmullations according to the invention will be explained by way of example.

Washing tests were carried out with these three detergents to determine the detergency and the bleaching action and, according to TGL 29798/01, the following use-value criteria were evaluated at 20 ° C. in the prescribed ratios:

Washing power with 51.6%

Bleaching capacity with 25.8%
