## Abstract

Solid compositions for use in textile treatment, each comprising, based on the total weight of the solid composition, a total amount of each of —30% to 70% by weight of at least one peroxide compound, —10% to 20% by weight of at least one organic bleach activator, —5% to 50% by weight of hydrogencarbonate, calculated as sodium hydrogencarbonate, —0% to 5% by weight of surfactant, where the total amount of organic compound in the solid composition is 10% to 50% by weight, preferably 20% to 35% by weight, are thermally stable and can be stored reliably. They are suitable as an additive to conventional textile treatment compositions, especially to liquid washing compositions, and can be provided as a portion encased with a water-soluble material.

## Claims

### Claim 1

A solid composition for use in treatment of textiles comprising:
a sodium percarbonate present as a powder or granules in a total amount of about 32% to about 55% by weight based on the total weight of the composition,
tetraacetylethylenediamine present in a total amount of from about 10% to about 20% by weight based on the total weight of the composition,
a sodium hydrogen carbonate present as a powder or granules in a total amount of from about 7.5 to about 30% by weight based on the total weight of the composition, and
a surfactant present in a total amount of from about 1 to about 3% by weight based on a total weight of the composition,
wherein the total amount of organic compound in the solid composition amounts to from about 10% to about 50% by weight, and
wherein the solid composition is free of sodium silicate.

### Claim 2 (depends on 1)

The composition according to claim 1, wherein the sodium percarbonate has an average grain size (volume average) X50.3 of from about 0.40 to about 0.95 mm.

### Claim 3

A dosing unit for use in treatment of textiles, wherein the dosing unit comprises at least two chambers with walls made of a water-soluble material, and wherein
a) at least one of the chambers includes a first composition, the first composition comprising at least one surfactant, and
b) at least one additional one of the chambers includes a second composition comprising, each based on the total weight of the second composition, a total amount of:
from about 32% to about 55% by weight of sodium percarbonate,
from about 10% to about 20% by weight tetraacetylethylenediamine,
from about 7.5% to about 30% by weight of sodium hydrogen carbonate,
from about 1% to about 3% by weight of a surfactant,
wherein the total amount of organic compound in the second composition amounts to from about 10% to about 50% by weight; and
wherein the second composition is free of sodium silicate.

### Claim 4

A method for treatment of textiles wherein the method comprises the steps of:
dosing a composition for producing a wash liquor that comprises water, wherein the composition further comprises, each based on the total weight of the composition, a total amount of:
from about 32% to about 55% by weight of sodium percarbonate,
from about 10% to about 20% by weight traacetylethylenediamine,
from about 7.5% to about 30% by weight of a hydrogen carbonate,
from about 1% to about 3% by weight of a surfactant,
wherein the total amount of organic compound in the composition amounts to from about 10% to about 50% by weight, and the composition is free of sodium silicate;
and
bringing the resulting wash liquor in contact with the textiles.

### Claim 5 (depends on 1)

The composition of claim 1, wherein the total amount of organic compound in the solid composition amounts to from about 20% to about 35% by weight.

### Claim 6 (depends on 1)

The composition according to claim 1, wherein, based on the total weight of the composition, the sodium percarbonate is present in a total amount of about 47% by weight.

### Claim 7 (depends on 1)

The composition according to claim 1, wherein the sodium percarbonate has a bulk density of from about 0.70 to about 1.30 kg/dm3.

### Claim 8 (depends on 7)

The composition according to claim 7, wherein the sodium percarbonate has a bulk density of from about 0.85 to about 1.20 kg/dm3.

### Claim 9 (depends on 1)

The composition according to claim 1, wherein the sodium percarbonate has an average grain size (volume average) X50.3 of from about 0.50 to about 0.90 mm.

### Claim 10 (depends on 1)

The composition according to claim 1, wherein the sodium hydrogen carbonate has a bulk density of 0.9 to 1.1 kg/dm3 as measured according to ISO 697.
