Abstract
An oral care implement has one or more components, such as a handle or a gripping portion thereof, prepared from an elastomeric propylene-ethylene copolymer. The elastomeric copolymer provides a comfortable and non-slippery gripping surface in a variety of conditions, including both wet and dry environments, and also provides flexible characteristics which are particularly well suited for hinged handle designs.
