Abstract
Abstract A detergent product comprises a water-permeable closed bag containing a particulate detergent composition with a bulk density of at least 0.5 g/cc. The bag material may be insoluble and formed from paper or plastics material sheet. The pore size distribution of the bag material is selected in relation to the particle size distribution of the detergent cbmposition to give less than 5% dusting. The bag may contain conventional detergent compositions and or other fabric treatment materials. The high bulk density powder enables the bag to be smaller with a saving in the bag material or to be less completely filled which gives better powder discharge in the wash.

Claim 1
Independent Claim
30 words
A detergent product comprising a closed water-permeable bag containing a particulate detergent composition, characterised in that the particulate detergent composition has a bulk density of at least about 0.5 g/cc.
Claim 2
Dependent Claim
30 words
A detergent product comprising a closed water-permeable bag containing a particulate detergent composition, characterised in that the particulate detergent composition has a bulk density of at least about 0.5 g/cc.
Claim 3
Dependent Claim
20 words
A detergent product according to Claim 1, characterised in that the closed water-permeable bag is formed of a water-insoluble material.
Claim 4
Dependent Claim
32 words
A detergent product according to Claim 1, characterised in that that material of which the closed water-permeable bag is formed is coated with a water-soluble or removable water-insoluble agent to reduce dusting.
Claim 5
Dependent Claim
23 words
A detergent product according to Claim 1, characterised in that the bag is closed by seals formed by heat-sealing or cold pressure sealing.
Claim 6
Dependent Claim
25 words
A detergent product according to Claim 1, characterised in that the particulate detergent has a bulk density of from' about 0.6 to about 0.8 g/cc.
Claim 7
Dependent Claim
41 words
A detergent product according to Claim 1, characterised in that the detergent composition is selected from fully formulated detergent compositions, bleaches, bleach precursors., fabric softeners, starch, perfumes, anti-bacterial agents, anti-static agents, whitening agents, blueing agents, stain removing agents and mixtures thereof.
Claim 8
Dependent Claim
54 words
A detergent product according to Claim 1, characterised in that the material of which the closed water-permeable bag is formed has a porosity which is such in relation to the particle size distribution of the particulate detergent composition that no more than about 5% of the particulate detergent composition can pass through the material.
Claim 9
Dependent Claim
25 words
A detergent product according to Claim 7, characterised in that no more than about 1% of the particulate detergent composition can pass through the material.
Claim 10
Dependent Claim
38 words
A detergent product according to Claim 1, characterised in that the amount of particulate detergent composition contained in the closed water-permeable bag is less than 50% of the maximum amount of such detergent which the bag could contain.
Claim 11
Dependent Claim
26 words
A detergent product according to Claim 1, characterised in that the bag includes at least two compartments containing different detergent ingredients, at least one of said
Claim 12
Dependent Claim
52 words
A detergent product acording to Claim 1, characterised in that the pore size of the bag material is sufficient to allow water and also particles of about 10 microns and smaller to pass through and in that the bag material has a weight of less than 6 0 g/ m 2 .
