Healthcare and cosmetic compositions containing nanodiamond

Abstract

Nanodiamonds can be included in various compositions to take advantage of the ability of nanodiamond to reduce or prevent the formation of free radicals through administering the particles to a subject. Nanodiamonds can be administered through a variety of means to a tissue area of the subject, thus reducing or preventing the formation of free radicals and reducing the signs of ageing. The nanodiamonds may be incorporated into a composition that includes a variety of components including biologically or cosmetically acceptable carriers, dispersants, and additional active ingredients.

Description

RELATED APPLICATIONS [0001] This application is a continuation-in-part of U.S. patent application Ser. No. 10 / 814,660, filed Mar. 30, 2004, which is hereby incorporated herein by reference in its entirety.FIELD OF THE INVENTION [0002] The present invention relates to cosmetic and remedial health compositions and to methods for the preparation thereof. Accordingly, the present invention involves the fields of chemistry, healthcare, materials science, and cosmetics. BACKGROUND OF THE INVENTION [0003] Diamond is the hardest material known and is commonly used as a superabrasive for removing excess materials. Typical superabrasive products include diamond saws, grinding wheels, polishing pads and the like. Diamond superabrasives have been commercially available in a number of mesh sizes. For example, diamond saws typically incorporate diamond particles having a U.S. mesh size of 18 (about 1 mm) to 60 (about 0.25 mm). Grinding applications often employ diamond particles having a size of ...
