What is boron nitride?
Boron nitride is a crystal composed of nitrogen atoms and boron atoms. The chemical formula is BN. It has a variety of crystal structures, and each crystal type has its own unique and excellent properties. As a new material, boron nitride has been more and more widely used in various new technologies and new products. Its application has improved the technological level of contemporary industry and promoted the development of the new material industry to a deeper and broader field.
What is hexagonal boron nitride?
Hexagonal Boron Nitride (HBN) --- The crystal structure is similar to graphite, so it is called "white graphite". It is a lubricant with excellent performance, usually a white powder.
Hexagonal boron nitride is a good conductor of heat and an electrical insulator. It has high chemical stability, low friction coefficient and excellent lubricating performance, especially at high temperatures. It still has excellent self-lubricating ability.
Advantages of Hexagonal Boron Nitride in the Cosmetic Field
In the field of beauty, the efficiency and permeability of active substances into the skin are directly related to particle size. Cosmetic particle size is important because smaller particle diameters may increase surface area and may encapsulate cosmetic active substances.
The hexagonal boron nitride (h-BN) nanomaterials can control the size of the synthesized particles. Hexagonal boron nitride has obvious advantages in cosmetics, especially sunscreen products. It allows the nanostructure to be adjusted in different formation stages, thereby controlling the size and surface area; and it has excellent performance in dispersion, non-toxic and transparent And chemically inert.
