Abstract
Makeup compositions having enhanced transfer resistance including at least one hydrophilic film former. The makeup can be a water-in-oil emulsion having the hydrophilic film former in the internal water phase and at least one pigment in the external oil phase. The makeup composition can also be a suspension of one or more cationically-coated pigments in water in which the hydrophilic film former is dissolved. The hydrophilic film former may also be an anionic gelling agent, whereby the cationically-coated pigment and the anionic gelling agent form a water-dispersable complex that upon application to the skin forms an insoluble pigmented salt having enhanced transfer resistance.
