Abstract
An improved cosmetic brush for the application of powder is made using synthetic bristles of nylon or polyester having a median diameter of about 3 mils and having a gentle random and irregular wavy configuration along the lengths of the bristles. The random and irregular wavy configuration provides the advantages of improving the fullness of the brush and at the same time improving both pick-up and lay-off of powder.
