Definitions
- TAED tetraacetylethylenediamine
- Modern detergents therefore consist of a combination of Detergents as detergent substances, bleaches and the Detergent strengthening additives, the so-called builders, the remove the hardness of the wash liquor on the one hand and on the other hand Prevent deposits of inorganic salts on the laundry and thereby for a "soft grip" of the laundry after Ensure the washing process.
- Polymeric phosphates are considered to be excellent builders, in particular Sodium tripolyphosphate. Because of the risk of eutrophication of the rivers and lakes due to the phosphate content in domestic wastewater the use of zeolites was proposed as a builder.
- DE-34 16 669 A1 has therefore proposed that Detergent additionally 1 to 20 wt .-% crystalline layered silicate or add alkali silicate. This could make a "softer Handle "of the laundry can also be achieved when as a builder Zeolites are used; the storage stability of the detergent however, was not affected by this.
- EP-A-0 263 520 describes a detergent which, in addition to the usual constituents, contains 0 to 5% by weight of a quaternary ammonium compound and 1 to 30% by weight of a plasticizer system consisting of 10 to 90% by weight of an alkylamine and 90 to 10% by weight of a crystalline sheet silicate of the formula Me 2 Si x O 2x + 1 .yH 2 O, in which Me contains an alkali metal or H, x is a number less than 7 and y is a number less than 7x.
- EP-A-0 028 432 describes a detergent composition which contains, inter alia, sodium tripolyphosphate, insoluble silicates, TAED, alkylbenzyl sulfonates, ethoxylated C 15 alcohols, sodium perborate tetrahydrate, brighteners and sodium sulfate.
- EP-A-0 634 484 describes packaged granules Detergent compositions where packaging determined Has water vapor permeability values.
- the invention thus relates to a detergent of the type described above Kind, which is characterized in that it the bleach is sodium percarbonate and the amount of bleaching agent is such that 0.5 to 4 wt .-%, in particular 1.0 to 2.5% by weight of washing-active oxygen in the detergent available.
- alkylbenzenesulfonates can act as a detergent, alkali salts of alkylbenzenesulfonates, higher Alkyl sulfonates and / or higher fatty alcohol polyethoxylate sulfates, especially with alkyl residues with an average of 10 contain up to 18 carbon atoms in the alkyl group.
- carboxymethyl cellulose it can be used as a washing aid, carboxymethyl cellulose, carboxymethyl starch and / or methyl cellulose in amounts of up to 10 % By weight.
- Crystalline layered silicates can according to the DE-34 13 571 A1 can be produced.
- the determination of the wash-active oxygen (AVOX) of the bleach and the detergent was carried out according to Dr. (. NaBO 3 4H 2 O) E. Heinerth, surfactants, 2 (1965) 180.
- the investigated sodium perborate tetrahydrate had a AVOX number of from 10% by weight; the sodium perborate monohydrate (NaBO 3 .H 2 O) had an AVOX number of 15% by weight; the sodium percarbonate (2 Na 2 CO 3 .3H 2 O 2 ) had an AVOX number of 13.5% by weight.
- the washing power (bleaching effect) of the detergent was determined as Whiteness of the test fabrics (WFK polyester / cotton with Tea soiling, order code 20 G) determined according to DIN 44983.
- the storage tests were carried out according to the following forced test conditions:
- the detergent to be examined was stored in a climatic cabinet at a relative humidity of 70% at a temperature of 37 ° C.
- the detergent was packed in a wax box.
- the water vapor permeability of the packaging was 0.4 g / m 2 ⁇ h.
- Table 1 shows the detergent formulations tested listed.
- Table 2 shows the degradation values of the bleaching agent in Depends on the time after the forced storage test conditions compiled.
- two were commercially available Detergent based on zeolite and sodium tripolyphosphate included in Table 2.
- the bleach breakdown, especially sodium percarbonate is present of zeolite very large.
- Table 3 lists the test results according to DIN 44983 for the different detergent formulations which were determined in accordance with equation I. It can be seen from the test values that the bleaching action is increased when crystalline layered silicate is used as the builder instead of zeolite. In the presence of TAED there is a synergistic increase in the washing power (bleaching effect) of the detergent.

Description
Im Klimaschrank wurde das zu untersuchende Waschmittel bei einer relativen Luftfeuchtigkeit von 70 % bei einer Temperatur von 37°C gelagert. Das Waschmittel war dabei in einem Wachs-Karton verpackt. Die Wasserdampfdurchlässigkeit der Verpackung betrug 0,4 g/m2 · h.
Aus den Testwerten ist zu entnehmen, daß die Bleichmittelwirkung gesteigert wird, wenn als Builder kristallines Schichtsilikat anstelle von Zeolith eingesetzt wird. In Anwesenheit von TAED erfolgt eine synergistisch gesteigerte Waschkraft (Bleichwirkung) des Waschmittels.
