The prevention of color transfer to cups and clothing is very important in lip color products. A common method of minimizing color transfer is to use a film-forming polymer dissolved in a volatile oil in a lip color formula. However, this approach requires the user to wait several minutes to allow solvent evaporation. The result is often unsatisfactory as color transfer can still take place even after drying. To prevent color transfer effectively without any waiting period, we devised a novel dual approach utilizing over-coating. The first is to reduce the mobility of the lipstick film by a dynamic diffusion of the gelling agent from the over-coating to significantly increase the lipstick film viscosity. This is accomplished by carefully controlling the heat of immersion of the solvent in the over-coating such that its value is lower than that of the lipstick. Secondly, a continuous lipophobic film is formed over the applied lipstick film by allowing a lipophobic materials in the over coating to penetrate into the lipstick film through dynamic migration. Extensive investigations on solubility and heat of immersion of many lipophobic materials revealed polyperfluoromethylisopropylether (PF) to be the most suitable for this purpose. From our infrared spectroscopy studies, we were able to confirm the dynamic migration of both silica and PF into the underlying applied lipstick film, when incorporated into a protective over-coating. We tested our new approach in practical applications by formulating a novel film-former designed to be worn over applied lipstick and found that the film provides perfect and immediate long-lasting color protection without a long waiting period after application.
