## Abstract

The present invention provides a water-soluble package comprising a water-soluble substrate and a powder coating on an exterior surface of the water-soluble substrate, wherein the water-soluble substrate encloses a composition and the powder coating includes a powdered bittering agent, a method of making such water-soluble packages and their use, in particular for washing dishes or laundering textiles.

## Claims

### Claim 1

A water-soluble package consisting of a water-soluble substrate enclosing a composition forming at least one compartment, and a powder coating on an exterior surface of the water-soluble substrate, wherein the powder coating consists of a powdered bittering agent, and wherein the powdered bittering agent has an average particle size of 0.1 to 200 microns.

### Claim 2 (depends on 1)

The water-soluble package according to claim 1, wherein the powdered bittering agent is selected from the group consisting of denatonium benzoate, denatonium saccharide, quinine, or a salt of quinine.

### Claim 3 (depends on 1)

The water-soluble package according to claim 1, wherein the water-soluble substrate is selected from the group consisting of polyvinyl alcohol, modified polyvinyl alcohol, polyvinyl acetate, carboxymethylcellulose or hydroxypropyl methyl cellulose.

### Claim 4 (depends on 1)

The water-soluble package according to claim 1, wherein the package has two or more compartments.

### Claim 5 (depends on 1)

The water-soluble package according to claim 1, wherein the composition is a dishwashing or laundry detergent composition.

### Claim 6

A method of producing a water-soluble package, the method comprising the step of:
coating a water-soluble substrate enclosing a composition with a powder coating composition,
wherein the powder coating composition consists of a bittering agent, and
wherein the powdered bittering agent has an average particle size of 0.1 to 200 microns.
