Abstract

A skin engaging member for a razor cartridge includes an erodible first layer and an erodible second layer below the first layer. Each layer includes a lubricious water soluble polymer and can include a water insoluble polymer. The second layer includes a fragrance that can be in the form of microcapsules or a suitable additive of the polymeric material(s). As the first layer erodes during normal use of the razor cartridge the second layer is eventually exposed dissolving or fracturing the microcapsules or otherwise releasing the fragrance. The fragrance is malodorous indicating to e.g. a vision impaired user that the optimal life of the razor cartridge is at or nearing its end. The first layer can also be provided with a non-malodorous fragrance. A third erodible layer can be provided between the first and second layer and can also include a fragrance. End-of-optimal-life indication can be rapid or gradual.

Claims

1. A skin engaging member in the form of a narrow elongated strip of dimensions suitable for placement on a razor cartridge, the skin engaging member comprising:

a first layer comprising an erodible skin engaging layer comprising a lubricious water soluble polymer; and

a second layer positioned below the first layer comprising an erodible lubricious water soluble polymer and a first fragrance of a first odor;

wherein the first odor is malodorous.

2. The skin engaging member of claim 1, wherein the first layer further comprises a second fragrance of a second odor.

3. The skin engaging member of claim 2, wherein the first odor and the second odor are different.

4. The skin engaging member of claim 2, wherein the second odor is non-malodorous.

5. The skin engaging member of claim 1, wherein the skin engaging member further comprises a third layer between the first layer and the second layer, the third layer comprising an erodible lubricious water soluble polymer and a third fragrance of a third odor.

6. The skin engaging member of claim 5, wherein the third odor and the first odor are different.

7. The skin engaging member of claim 5, wherein the third odor is malodorous.

8. The skin engaging member of claim 7, wherein the third odor is less malodorous than the first odor.

9. The skin engaging member of claim 1, wherein the second layer comprises a second layer core and a second layer sheath and the second layer core includes the first fragrance.

10. The skin engaging member of claim 2, wherein the first layer comprises a first layer core and a first layer sheath and the first layer core includes the second fragrance.

11. The skin engaging member of claim 5, wherein the third layer comprises a third layer core and a third layer sheath and the third layer core includes the first fragrance.

12. The skin engaging member of claim 1, wherein the skin engaging member further comprises a single sheath that encloses the first layer and the second layer.

13. The skin engaging member of claim 5, wherein the skin engaging member further comprises a single sheath that encloses the first layer, the second layer and the third layer.

14. The skin engaging member of claim 2, wherein the skin engaging member further comprises a third layer between the first layer and the second layer, the third layer comprising an erodible lubricious water soluble polymer and a third fragrance of a third odor.

15. The skin engaging member of claim 14, wherein the third odor and the first odor are different.

16. The skin engaging member of claim 14, wherein the third odor is malodorous.

17. The skin engaging member of claim 16, wherein the third odor is less malodorous than the first odor.

18. The skin engaging member of claim 14, wherein the third layer comprises a third layer core and a third layer sheath and the third layer core includes the first fragrance.
