Abstract
A fabric treatment product is in the form of a bag having at least two compartments containing particulate fabric treatment compositions. The bag has a first outer wall and an intermediate wall of water-insoluble but water-permeable material such as paper or nonwoven fabric, and a second outer wall of water-impermeable water-insoluble plastics sheet. In the washing machine the wash water first enters the compartment bounded by the first outer wall, which is water-permeable, and dissolves or disperses out its contents, for example, a detergent composition. The water subsequently penetrates the intermediate wall to enter the second compartment and dissolve or disperse out its contents, for example, a fabric conditioner.
