Absorbent articles comprising an odour control system

1. An absorbent article comprising:

a) a liquid permeable topsheet, a backsheet, and an absorbent element comprised between the topsheet and the backsheet, each of the topsheet, backsheet and absorbent element having a body facing side and a garment facing side; and

b) an odour control material, said odour control material comprising at least one inclusion complex of cyclodextrin with an organic compound which is dispersed in a matrix comprising a polysiloxane oil;

wherein the complexed cyclodextrin has less than 20% moisture by weight of the complexed cyclodextrin particles prior to their inclusion into the polysiloxane carrier.

2. An absorbent article according to claim 1 wherein the cyclodextrin is selected from α or β cyclodextrin.

3. An absorbent article according to claim 1 wherein the organic compound has a Kovats Index between 500 and 2000, said Kovats Index being measured with a chromatographic column DB 5, 30 m, 0.25 mm, 1.00 μm, operating at 50-300° C., 4° C./min, 12.0 psi, constant flow.

4. An absorbent article according to claim 1 wherein the odour control material is applied on the body facing side or on the garment facing side of the topsheet.

5. An absorbent article according to claim 1 wherein the odour control material is applied on the body facing side of the backsheet.

6. An absorbent article according to claim 1 wherein the odour control material is applied on the body facing side or on the garment facing side of or within the absorbent element.

7. An absorbent article according to claim 1 further comprising an additional layer of material positioned between the topsheet and the absorbent element wherein the odour control material is applied on the body facing side or on the garment facing side of said layer.

8. An absorbent article according to claim 1 further comprising an additional layer of material positioned between the absorbent element and the backsheet wherein the odour control material is applied on the body facing side or on the garment facing side of said layer.

9. An absorbent article according to claim 1 , wherein the odour control material releases an organic compound upon being wetted.

10. An absorbent article comprising:

a) a liquid permeable topsheet, a backsheet, and an absorbent element comprised between the topsheet and the backsheet, each of the topsheet, backsheet and absorbent element having a body facing side and a garment facing side; and

b) an odour control material, said odour control material comprising at least one inclusion complex of cyclodextrin with an organic compound which is dispersed in a matrix comprising a polysiloxane oil;

wherein the complexed cyclodextrin are solid particles in the polysiloxane oil; and

wherein the complexed cyclodextrin has less than 20% moisture by weight of the complexed cyclodextrin particles prior to their inclusion into the polysiloxane carrier.

11. An absorbent article according to claim 10 , wherein the cyclodextrin is selected from α or β cyclodextrin.

12. An absorbent article according to claim 10 , wherein the odour control material releases an organic compound upon being wetted.

13. An absorbent article comprising:

a) a liquid permeable topsheet, a backsheet, and an absorbent element comprised between the topsheet and the backsheet, each of the topsheet, backsheet and absorbent element having a body facing side and a garment facing side; and

b) an odour control material, said odour control material comprising at least one inclusion complex of cyclodextrin with an organic compound which is dispersed in a matrix comprising a polysiloxane oil;

wherein the complexed cyclodextrin are solid particles in the polysiloxane oil;

wherein the complexed cyclodextrin has less than 20% moisture by weight of the complexed cyclodextrin particles prior to their inclusion into the polysiloxane carrier; and

wherein the odour control material releases an organic compound upon being wetted.
