Abstract
A mascara applicator is disclosed that comprises a conventional twisted wire core brush with a plurality of radially extending bristles regularly disposed in a first orientation. A cylindrically configured helix is twisted onto the brush around the wire core such that the brush bristles extend radially between successive loops of the helix. The helix moves at least some of the bristles to a second orientation such that one or more characteristics of the brush may be altered. Characteristics of the original brush that may be altered include mascara retention, mascara application and combing characteristics, as well as the appearance of the brush. The dimensions of the helix, the pitch of the helix and the thickness of the helix body are each pre-selected to yield the desired characteristics in the finished brush.
