摘要:
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.

摘要:
Compositions and methods are disclosed for imparting super-hydrophobic properties to cosmetics, which can be used to significantly improve water repellency compared to traditional cosmetics. The compositions comprise a hydrophobic film former, and hydrophobic particles, in an emulsion base.
摘要:
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.
摘要:
The invention relates to topical compositions comprising inorganic particles coated or embedded on the surface of macroscopic particles, methods of preparing the compositions, and uses thereof. The topical composition may be delivered and applied to a surface, thereby improving the appearance of the surface. This composition can reduce the visibility of textural imperfections, such as fine lines, wrinkles, and scars, as well as color imperfections, such as age spots and blemishes. The treatment of inorganic particles on the surface of macroscopic particles can be achieved by three methods, including mechanofusion, physical adsorption, and pre-emulsification into macroscopic particles. This invention also relates to methods of using the composition in a cosmetic or dermatological application, as well as, in an industrial application.
摘要:
Described herein is a cosmetic composition comprising a mixture of volatile solvents with varying evaporation rates, wherein at least two of the volatile solvents are in combination with a film former. A single application of a cosmetic composition as described herein provides transfer resistance, long wear, and comfort and as such, may be used in lipsticks, lip glosses, mascara, hair care products, and other such cosmetics for which transfer resistance, long wear and comfort are desired properties.
摘要:
Compositions for altering the color of teeth, including tooth-coating compositions comprising a colorant and an acrylate polymer. Colorants among those useful herein include whiteness-imparting particulate materials, such as hydroxyapatite.
摘要:
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.
摘要:
Compositions and methods for the in situ formation of hydrosilylation (addition) cross-linked organosiloxane films are disclosed. The disclosed films are long-lasting, flexible, transfer-resistant, and water-proof. The film-forming compositions generally comprise alkoxy-terminated organosiloxane polymers and a catalyst and are useful for formulating cosmetics and personal care products.
