1. A handle for a razor that is made of a composition comprising:
a) from 80 to 90% by weight of a mixture of polylactic acid (PLA) and bio-polyethylene (bio-PE), wherein the weight ratio polylactic acid/bio-polyethylene (bio-PE) polymer ranges from 70/30 to 80/20; and
b) from 10 to 20% by weight of mineral fillers chosen in the group consisting of calcium carbonate and crushed shells of oyster,
wherein the mineral fillers are present in an amount sufficient to increase the heat deflection temperature and the crystallization temperature of the mixture, and
the weight % being relative to the total weight of the handle for the razor.
