Abstract:
This disclosure provides sunscreen products that contain metal oxide powders having discrete size distributions. Metal oxide powders include, for example, zinc oxide and titanium dioxide. Sunscreen products made in accordance with the principles of this disclosure contain metal oxide powders having primary particle sizes of about 10-30 ran and about 50-200 nm.
Abstract:
A range of low-dust or dust-free powder-derived products is provided for cosmetics and other uses to avoid hazards arising from liberation during handling. The products can be made by employing suitable quantities of hydrophilic solvents or binders.
Abstract:
A composition comprising a pigment particle that is coated with a cationic material and isopropyI titanium triisostearate. The pigment particle can be included in a cleansing composition for deposition on a surface, such as skin.
Abstract:
The present invention provides compositions for natural cosmetic products and, more particularly, to natural ester, wax or oil treated pigments, the products of such treated pigments and cosmetic products incorporating pigments treated with natural ingredients.
Abstract:
Hard-to-coat color lakes and other powders useful in cosmetics and other industries are coated with a duplex coating system comprising basic and nonbasic functionalized coating components, for example a basic functionalized aminopolysiloxane and a nonbasic alkoxypolysiloxane. Control of bleeding of a color lake into aqueous media is possible. A novel duplex coating system, treatment process, treated powder and cosmetic formulation containing same are disclosed.
Abstract:
The present invention provides UV attenuating nanoparticles entrapped in porous particulates that are coated with a wax material. The porous particulates also include a fatty acid applied to the wax coating. Also provided is a method of producing a powder comprised of UV attenuating nanoparticles entrapped in porous particulates coated with a wax material. Further provided is a composition, such as a cosmetic composition, which includes the porous particulates loaded with the UV attenuating nanoparticles. Alternatively, large particle sunscreen powders useful as ingredients in cosmetic compositions and in dispersions for incorporation into cosmetic compositions comprise a UV shielding agent in a matrix material. The macroparticle powders can be used in a wide range of cosmetic formulations, including sunscreens, eyeshadow, mascara, foundation, blusher, toner, lipstick and other compositions requiring ultraviolet protection.

Abstract:
Disclosed is a composition having a substrate comprising metal oxide particles. The substrate has a coating thereon that includes an organic dispersant present in an amount that renders the substrate self-dispersible. Also disclosed is a composition, such as a cosmetic composition, that includes the self-dispersible coated substrate, and a process that includes coating a particulate metal oxide with an organic dispersant to render the metal oxide self-dispersible.
