Problems solved by technology

However, with the deepening of research, some problems have also been exposed, for example, nano-diamond has a higher specific surface energy, a larger specific surface area, and is in a thermodynamically unstable state. In addition, the surface activity of nano-diamond is also Very large, so agglomeration often occurs between particles

Abstract

The invention discloses a preparation method of a nano-diamond beauty makeup product, and belongs to the field of diamond application. The preparation method comprises the following four parts: strong acid treatment of the nano-diamond, N2 atmosphere vacuum heat treatment, surface functionalization treatment of the nano-diamond, and combination of the nano-diamond and vitamin C. The method is simple to operate, the product has the properties of low toxicity, biocompatibility, chemical inertness, fluorescence effect and the like, and the nano-diamond can be combined with the skin surface, so that the transdermal moisture loss is reduced, the function of the water lipid skin surface is influenced, and the skin is protected from aging.

Description

technical field [0001] The patent of the present invention relates to the field of diamond applications, especially a method for preparing nano-diamond cosmetic products. Background technique [0002] From the discovery of the use of diamond to the synthesis of synthetic diamond, especially since the synthetic diamond in my country, the development of diamond has made great progress. For a long time in the past, various synthetic methods of diamond have provided a solid foundation for the application and research of diamond. Among them, nano-diamond has attracted the attention of many researchers because of its excellent properties, such as low toxicity, biocompatibility and large specific surface area, which are different from other materials, and they have been studied in depth. Its surface modification and modification, and then the research on combining with biological macromolecules is gradually carried out. [0003] At present, nano-diamonds are widely used in the fie...
