Talk about the application of hexagonal nano boron nitride in the cosmetic field
1. Advantages of hexagonal boron nitride nanoparticles in the cosmetic field
In the cosmetic field, the efficiency and permeability of the active substance into the skin is directly related to the particle size, and the cosmetic particle size is important because smaller particle diameters may increase the surface area and may encapsulate the cosmetic active. The hexagonal boron nitride (h-BN) nanomaterial can control the size of the composite particles. Hexagonal boron nitride has obvious advantages in cosmetics, especially sunscreen products, which allows the nanostructures to be controlled at different stages of formation to control size and surface area; and it has excellent properties in dispersion, non-toxic, transparency and chemically inert.
2. Infrared radiation sunscreen research of Nano Boron Nitride
It is well known that solar radiation can damage the health of the skin. The range of solar energy usually reaches the surface of the earth is ultraviolet and infrared. The effects of UV light are harmful to skin health and may result in increased cancer incidence, aging and other undesirable skin changes, and are responsive to sunburn, erythema and inflammation. Infrared rays increase the damage and pre-aging of ultraviolet rays to the skin, and infrared radiation may also have the potential for photocarcinogenesis.
The cosmetics industry’s research on sunscreen products has been in place for a long time. Sunscreens have been developed using nanoscience and nanotechnology knowledge, such as nano titanium dioxide, an important cosmetic material for sunscreen UV rays. However, for infrared radiation protection, there are very few sunscreen studies, and in this regard, it is necessary to make sunscreens that provide UV and IR protection. Boron nitride nanopowders are potential materials because they control the size of the composite particles, which is an important factor in the use of sunscreens. It also reduces the luster of oily skin due to its high thermal conductivity. Titanium dioxide nanoparticles containing nanostructured boron nitride are a perfect combination that can be used as a cosmetic to protect the body from the infrared radiation of the sun.
Of course, the application of hexagonal boron nitride nanoparticles in the field of cosmetics is not only sunscreen. The variety of cosmetics is very rich. In addition to cosmetics, the application of other fields of hexagonal boron nitride nanoparticles is also very extensive, and can be applied to ceramics manufacturing, such as crucible, aluminum evaporation boats, circuit board substrates and high temperature lubricants, are also used as structural materials for nuclear reactors and rocket engine units.
