See full text

A filament for an oral care implement has a longitudinal axis and a substantially cross-shaped cross-sectional area extending in a plane substantially perpendicular to the longitudinal axis. The cross-shaped cross-sectional area has four projections and four channels, the projections and channels are arranged in an alternating manner. The cross-sectional area has an outer diameter, and each channel has a concave curvature formed by neighboring and converging projections. The concave curvature has a radius which is within a range from about 0.015 mm to about 0.12 mm, and the ratio of the outer diameter to the radius is within a range from about 2.5 to about 12.
