Boron Nitride
What is Boron Nitride?
Boron Nitride is a synthetic inorganic compound with a hexagonal crystal structure akin to graphite, formed through high-temperature chemical reactions involving boron sources and nitrogen. This white, ultra-fine powder is prized in cosmetics, particularly in makeup foundations, powders, and primers, as well as some skincare formulations. It functions by creating a slippery surface that improves product spreadability, absorbing sebum and moisture to mattify skin and reduce shine, and scattering light to opacify formulas for a uniform appearance. Its inert nature allows it to maintain skin's moisture balance without penetration, contributing to a soft, velvety finish that enhances wear and aesthetic appeal in various product types.
