Abstract:
A photoprotective composition, in particular a cosmetic composition, that includes particles of photonic material having a polymeric multilayer interference structure, where at least two layers of the structure contain an amphiphilic polymer.
Abstract:
Hair was coated with polymer-containing fluid and then hot pressed to form a composite of hair and a polymer film imprinted with a nanopattern. Polychromatic light incident on the nanopattern is diffracted into dispersed colored light.
Abstract:
The invention relates to a cosmetic composition for creating a cosmetic coating having a metallic and multicolored iridescent appearance, comprising a liquid phase and a PVD aluminum pigment, wherein said PVD aluminum pigment has diffractive structures containing from approximately 5,000 to approximately 20,000 structural elements per cm and a metallic aluminum content of from 90% to 100% by weight, based on the weight of the aluminum pigment, and is present in the cosmetic composition at a pigmentation level of from 1.0 to 8.0% by weight, based on the total weight of the cosmetic composition. The invention further relates to an artificial fingernail.

Abstract:
The invention relates to photoprotective personal care compositions. It is an object of the present invention to provide for benefits of photoprotection over the visible light region while giving the skin a pleasing even appearance. This is achieved by using a selective combination of an inorganic pigment particle that has a specific light scattering property (reflection of incident light predominantly in the blue region) and an organic dye that has a specific light absorption property (absorption of incident light predominantly in the blue region).

Abstract:
A method of instantly reducing the appearance of wrinkles and skin imperfections while smoothing the skin, which comprises applying a cosmetic composition comprising a fractal particle based gel.
Abstract:
Cosmetic compositions comprising a fibrous pigment having an average diameter greater than 0.2 microns and an average aspect ratio greater than 5, and methods of using said compositions for imparting a pigmented film on skin or imparting a lightening appearance of skin are provided. The compositions optionally comprise from 0.1 to 30% of a coloring agent, selected from pigments, lakes, and dyes. The appearance of skin to which the compositions have been topically applied as a cosmetic film possesses L*, a*, and b* color space values and angular reflection properties closer to those of natural skin than an identical composition wherein the fibrous pigment has an average aspect ratio of less than 5.
Abstract:
An object of the present invention is to provide a core-shell-type cerium oxide microparticle, a dispersion solution comprising the microparticle, and a process for production of the microparticle or dispersion solution, and to achieve the object, the present invention provides a core-shell-type cerium oxide microparticle which has an average particle diameter of 30 to 200 nm and a coefficient of variation therein no greater than 0.25, and in which the secondary particle forming the core portion is spherical in shape and a polymer is attached to its surface, a dispersion solution of this cerium oxide microparticle and a dry powder from the cerium oxide microparticle dispersion solution, and a process of producing a core-shell-type cerium oxide microparticle or a dispersion solution thereof, which comprises the steps of: mixing a cerium salt and a polymer in an organic solvent to obtain a mixture; and heating this mixture under reflux at a prescribed temperature to precipitate core-shell-type cerium oxide microparticles, wherein the cerium salt is cerium nitrate and the particle diameter of the microparticles is adjusted using the molecular weight of the polymer.
Abstract:
Cosmetic or dermatological compositions and substrates, containing a NIR light-emitting material, and methods for stimulating healing and/or regenerative properties in the skin, hair and/or scalp are provided.
