The present invention relates to cosmetic, dermatological, and pharmaceutical compositions that deliver, in an acceptable vehicle or carrier comprising a film former or wax and an effective amount of nanoparticles and one or more pigments and methods for improving the appearance of a biological surface by altering the optical properties of the biological surface. The compositions of the invention enhance color and may be topically applied to the biological surface in an amount effective in improving the aesthetic and natural appearance of the biological surface.

Nanoparticle compositions providing enhanced color for cosmetic formulations

High concentrations of dye may be prepared in combination with thermoplastic polymers and used in optical polymers as monomeric and dimeric molecular solutions. The method of preparing high concentration levels allows the control over the aggregation of dye molecules that is required to maintain effective nonlinear operation. The present invention is applicable to many systems and is essential to the successful production of working optical limiting devices and other optically transparent polymeric devices, as well as other photonic applications, such as nonlinear optics.
