The invention relates generally to gels or viscous fluids formed by the coordination of certain amino-functionalized siloxanes with titanates and the use of the same in cosmetic compositions, including for providing long-wearing, comfortable films on a keratinous surface (e.g., lips). The gels or viscous fluids may exhibit unique rheological properties, including shear thickening (dilatancy) and/or rheopecty, at low shear rates which may lead to self-leveling effects, including renewable shine and may exhibit high gloss and low shear.
