Abstract

An improved mascara brush comprises a twisted wire core holding a plurality of radially extending bristles forming a brush at an end of the core. The wire of the twisted wire core has a diameter of about 0.035 inch to about 0.050 inch, and the twisted wire core has a pitch of about 0.130 inch to about 0.250 inch. Preferably, the twisted wire core has a pitch of about 0.135 inch to about 0.200 inch. The wire is preferably formed of brass, copper or stainless steel, or a plastic coated metal Wire. The invention further comprises the method of fabricating the brush. The bristle density of the bristles per turn of the wire core will vary according to the diameter of the bristles; the full range of the bristle density is 10-80 bristles per turn, but more preferably is in the range of 20-35 bristles per turn, and most preferably 20-25 bristles per turn.
