Application of hexagonal boron nitride powder in the field of cosmetics

In the field of beauty, the efficiency and permeability of active substances entering the skin are directly related to particle size. The size of cosmetic particles is important because smaller particle diameters may increase surface area and potentially encapsulate cosmetic active substances. (取决于上下文，如"but"Hexagonal boron nitride(UG-BN01) Nanomaterials can control the size of synthesized particles. Hexagonal boron nitride has significant advantages in cosmetics, especially sunscreen products, as it allows for the regulation of nanostructures at different stages of formation, thereby controlling size and surface area; And it has excellent dispersibility, transparency, and chemical inertness.

As is well known, solar radiation can damage skin health, and the spectrum of solar energy that typically reaches the Earth's surface is ultraviolet and infrared. The influence of ultraviolet radiation is harmful to skin health, which may lead to an increase in the incidence rate of cancer, aging and other adverse skin changes. Infrared radiation can increase the damage and pre aging of the skin caused by ultraviolet radiation, and it may also have the potential to cause photoinduced cancer. The research on sunscreen products in the cosmetics industry has been going on for a long time. Currently, sunscreen products have been developed using knowledge of nanoscience and nanotechnology, such as nano titanium dioxide, an important cosmetic used for UV protection. However, there is little research on sunscreen for infrared radiation protection. In this regard, it is necessary to produce sunscreen that can provide UV and infrared protection.Boron nitride nanostructureIt is a potential material because it can control the size of synthetic particles, which is an important factor in use in sunscreen. Due to its high thermal conductivity, it can also reduce the shine of oily skin. TiO2 particles containing nanostructured boron nitride are a good combination and can be used as a cosmetic to protect the human body from infrared radiation from the sun.

Of course, the application of hexagonal boron nitride in the field of cosmetics is not only limited to sunscreen. The variety of cosmetics is already very rich. In addition to cosmetics, hexagonal boron nitride has a wide range of applications in other fields, such as ceramic manufacturing, such as pliers, aluminum plating evaporation boats, circuit board substrates, and high-temperature lubricants. It can also be used as structural materials for atomic reactors and rocket engine units.
