Lubricating strip

1. A lubricating strip for use in a wet shaving system which comprises a biodegradable polymer, wherein said polymer is selected from the group consisting of polyanhydrides, and the co-polymers thereof, polycarboxylic acids, and the co-polymers thereof, and polyorthoesters, and the co-polymers thereof, and wherein said polyanhydride polymer is selected from the group consisting of poly [bis(p-carboxyphenoxy)propane anhydride], poly-bis(p-carboxyphenoxy)methane, poly[bis(p-carboxyphenoxy)methane anhydride], and poly(p-carboxyphenoxy)hexane anhydride, and the co-polymers thereof.

2. A lubricating strip according to claim 1 , wherein said biodegradable polymer comprises a non-bulk eroding biodegradable polymer.

3. A lubricating strip according to claim 1 , wherein said biodegradable polymer comprises a surface-eroding non bulk-eroding biodegradable polymer.

4. A lubricating strip according to claim 1 , which further comprises a lubricant.

5. A lubricating strip according to claim 4 , wherein said lubricant is incorporated into a monomer, or monomers, comprising said biodegradable polymer.

6. A lubricating strip according to claim 4 , wherein said lubricant is selected from the group consisting of polyethylene oxide and cyclomethacone.

7. A lubricating strip according to claim 6 , wherein said lubricant comprises polyethylene oxide.

8. A lubricating strip according to claim 4 , wherein said polyanhydride co-polymer with sebacic acid is poly[1,3-bis(carboxyphenoxy)propane-co-sebacic acid].

9. A lubricating strip for use in a wet shaving system which comprises a biodegradable polymer, wherein said polymer is selected from the group consisting of polyanhydrides, and the co-polymers thereof, polycarboxylic acids, and the co-polymers thereof, and polyorthoesters, and the co-polymers thereof, and wherein said polyanhydride co-polymer comprises a polyanhydride co-polymer with sebacic acid or a fatty acid dimer.
