Abstract
A waterbase lipliner composition in the form of a liquid is provided which is especially adapted for use in conjunction with a wick-type nib pen which delivers lipliner through a capillary action, which lipliner composition includes a water-soluble organic pigment formed of FDA approved organic pigments, a water-soluble organic polymer film-former, which is a mixture of polyvinyl pyrrolidone and polyvinyl alcohol, and optionally one or more plasticizers, preservatives, moisturizers and/or humectants, and water as a carrier for the pigment. The lipliner composition of the invention has a viscosity of less than 750 cps and will pass through the wick of a wick-type nib pen by capillary action without clogging the wick.
