From the manufacturer:
Tarte's revolutionary eyeliner captures the high pigment concentration and staying power of a gel pot in an effortless pencil, no brush required! Even more unique is the proprietary formula which encapsulates rich mineral pigments in a 50% water concentration. By a process of hydrous pigmentation, cooling and refreshing pure water absorbs into skin to hydrate and replenish the delicate eye area, leaving behind an intense, long-wearing and pigment-rich color. Fortified with vitamin E, cucumber and aloe this soothing Aqua-Gel Eyeliner maintains moisture balance in the skin while treating with healing free radical fighters.
