Optical substrates such as films and sheets, and methods for making optical substrates are described. The optical substrates contain at least one layer that contains glass or polymeric materials and boron nitride particles. The boron nitride particles have the requisite optical properties as well as excellent thermal conductivity, thus minimizing the potential for cracks, waves and wrinkles due to excess heat generated in applications such as liquid crystal displays, projection displays, traffic signals, and illuminated signs.

Optical substrate comprising boron nitrade particles

A gel system comprising a fractal network of nanoparticles and macroscopic particles is disclosed. The gel system is capable of forming an “optical gel” effective to blurrfine lines and wrinkles as a consequence of the size domain differences between the fractal particles and the macroscopic particles. Cosmetic compositions comprising such gels and methods for their use are also disclosed.

Gel technology suitable for use in cosmetic compositions

Compositions comprising a gel system made from a combination of a fractal network of nanoparticles and translucent macroscopic particles, titanium dioxide and other color pigments is disclosed. The compositions are capable of forming an effective film on the biological surface such as skin to blurring fine lines and wrinkles while retaining a natural look of the skin as a consequence of synergy between the fractal particles, the macroscopic particles, titanium dioxide and color pigments. Also disclosed methods for their use.

Optical blurring pigment composition suitable for use in cosmetics

Compositions and methods are disclosed for imparting water repellency to the hair. The compositions generally comprise a first hydrophobic particulate material having a coefficient of dynamic friction of 0.5 or greater in combination with a second hydrophobic particulate material having a coefficient of dynamic friction less than 0.5.

Compositions for imparting superhydrophobicity

A method of instantly reducing the appearance of wrinkles and skin imperfections while smoothing the skin, which comprises applying a cosmetic composition in the form of an oil-in-water emulsion comprising a fractal particle based gel and refractive index matching polymers with respect to at least one of the fractal particles. The composition of the invention provides both optical blurring and skin smoothing effect on the skin.

Cosmetic composition containing novel fractal particle based gels having improved optical properties

A soft-focus cosmetic composition comprising about 3 wt. % or more fumed alumina particles, a method of enhancing the soft-focus effect of a cosmetic composition comprising combining the cosmetic composition with about 3 wt. % or more fumed alumina particles, and a method for disguising skin imperfections, which method comprises applying a cosmetic composition to the skin, wherein the cosmetic composition comprises about 3 wt. % or more fumed alumina particles.

Soft-focus cosmetic composition comprising fumed alumina

Disclosed herein are treated fumed silica particles comprising a modified polydialkylsiloxane on the surface thereof, a method for preparing treated fumed silica particles, and a rheological system comprising a polar liquid and treated fumed silica particles. Also disclosed are toner compositions comprising toner particles and treated fumed silica particles comprising a modified polydialkylsiloxane.
