Abstract
A powder-based lip liner cosmetic composition comprises: (1) a talc component; (2) a mica component; (3) a low luster pigment; (4) a substantially hydrophobic polymer; (5) an at least partially hydrophilic polymer; and (6) an emulsifier component. Preferably, the talc component includes talc coated with an aluminum salt of a long-chain fatty acid. Preferably, the mica component includes mica coated with an aluminum salt of a long-chain fatty acid. Preferably, the low luster pigment includes mica, titanium dioxide, and barium sulfate. Preferably, the cosmetic composition further comprises a skin-tone-dependent pigment, as well as ancillary components. The lip liner cosmetic composition of the present invention provides a long lasting lip line resistant to contact with surfaces and eliminates the problem of "bleeding" or "feathering" of lipstick into the lip liner. This is achieved by the insolubility of lipstick in the lip liner because of the low wax and oil content of the lip liner of the present invention. The lip liner of the present invention is preferably applied by the use of a water-wetted brush, unlike any other lip liners previously available.
