## Abstract

A packaged detergent composition and/or additive comprises at least one oxygen releasing compound for use with a device for dispensing and/or dosing the detergent composition and/or additive into an automatic dishwashing machine over a plurality of washing cycles, wherein the package is made of a material with an oxygen transfer rate of more than 10 cm3/m2/bar/24 h, preferably more than 50 cm3/m2/bar/24 h, and most preferably more than 100 cm3/m2/bar/24 h, measured at 23° C. and 0% Equilibrium Relative Humidity. A method of packaging the detergent composition and/or additive is also described.

## Claims

### Claim 1

Method of packaging at least one detergent composition or additive comprising at least one oxygen releasing compound for use with a device placed in the interior of the dishwashing or washing machine for dispensing or dosing said detergent composition or additive into an automatic dishwashing machine over a plurality of washing cycles comprising the step of receiving and holding the at least one detergent composition or additive in a material that is a copolymer on the basis of cyclic olefins and linear olefins with an oxygen transfer rate of more than 10 cm3/m2/bar/24 h, measured at 23° C. and 0% Equilibrium Relative Humidity.

### Claim 2 (depends on 1)

The method according to claim 1 wherein the material has a moisture vapour transfer rate of less than 20 g/m2/24 h, measured at 25° C. and 50% Equilibrium Relative Humidity.

### Claim 3 (depends on 1)

The method according to claim 1 wherein the material is stable at 90° C. for more than 24 h.

### Claim 4 (depends on 1)

The method according to claim 1, wherein the material is stable within the pH range of from pH 13 to pH 2.

### Claim 5 (depends on 1)

The method according to claim 1 wherein the detergent composition or additive has an active oxygen content of less than 3 wt.-%.

### Claim 6

A packaged detergent composition and/or additive composition and/or additive comprising at least one oxygen releasing compound for use with a device for dispensing or dosing said detergent composition or additive into an automatic dishwashing machine over a plurality of washing cycles, wherein the package is made of a material consisting of a copolymer on the basis of cyclic olefins and linear olefins being oxygen permeable with an oxygen transfer rate of more than 10 cm3/m2/bar/24 h, measured at 23° C. and 0% Equilibrium Relative Humidity.

### Claim 7 (depends on 6)

The packaged detergent composition and/or additive according to claim 6, wherein there are conditions, in the automatic dishwashing machine of a temperature of higher than 40° C., and a relative humidity of from 10% to 100%.

### Claim 8 (depends on 6)

The packaged detergent composition according to claim 6, wherein the material has a moisture vapour transfer rate of less than 20 g/m2/24 h, measured at 25° C. and 50% Equilibrium Relative Humidity.

### Claim 9 (depends on 6)

Package according to claim 6 wherein the material is stable at 90° C.

### Claim 10 (depends on 6)

Package according to claim 6 wherein the material is stable within the pH range of pH 13 to pH 12.

### Claim 11 (depends on 6)

Package according to claim 6, wherein the detergent composition or additive has an active oxygen content of less than 3 wt.-%.

### Claim 12 (depends on 6)

Package according to claim 6 wherein the package is a blister pack with a plurality of compartments for receiving unit doses of the detergent composition and/or additive.

### Claim 13 (depends on 12)

The packaged detergent composition and/or additive according to claim 12, wherein the blister pack has a sufficient mechanical stability under the washing conditions in the dishwashing machine.

### Claim 14 (depends on 12)

The packaged detergent composition and/or additive according to claim 12, wherein the blister pack fits geometrically in the dishwashing machine.

### Claim 15 (depends on 14)

The packaged detergent composition and/or additive according to claim 14, wherein the blister pack fits in the plate space of the lower rack of the dishwashing machine.

### Claim 16 (depends on 6)

The packaged detergent composition and/or additive according to claim 6 wherein the material is stable at 80° C. for more than 24 h.

### Claim 17 (depends on 6)

The packaged detergent composition and/or additive according to claim 6 wherein the material is stable at 70° C. for more than 24 h.
