ORGANOSILICON COMPOUNDS, FATTY ACIDS AND OILS WITH HOMOGENOUS SILICON NANOPARTICLE DISPERSIONS

摘要

The invention provides homogenous dispersions of luminescent silicon nanoparticles in organoslicoon compounds, fatty acids and oils. In methods of the invention, a fatty acid or oil and silicon nanoparticle homogenous dispersion is formed by mixing. The dispersion of nanoparticles in organosilicon compounds, fatty acid(s) or oil(s) can used as a delivery mechanism to homogenously incorporate the nanoparticles into a variety of cosmetic compounds and oils, such as foundation creams and other make-up products, sun tan lotions, sun tan oils, etc. Compounds of the invention with homogenous nanoparticle dispersions display homogeneous UV/blue absorption as well as down conversion to visible luminescence. The compounds can be tailored to exhibit white luminescence under UV illumination. Preferred skin care compounds provide a pleasing cosmetic effect in response to light. Preferred skin care compounds also provide uv protection.
