Boron nitride which functions in cosmetics as a slip modifier (ie, it has a lubricating effect). Boron nitride is an inorganic compound with a crystalline form that can be hexagonal, spherical, or cubic; the hexagonal form is presumed to be used in cosmetics. The highest reported concentration of use of boron nitride is 25% in eye shadow formulations.
Boron nitride is reported to function in cosmetics as a slip modifier, which means it purportedly helps other substances to flow more easily and more smoothly, without reacting chemically, much like graphite. This ingredient is a type of ceramic, having the smoothness and the chemical and thermal inertness associated with most ceramics.
Our Boron Nitride is a soft, silky white mineral powder. It is used as an additive to improve the "slip" of a product(how smoothly the product applies) as well as "adhesion" (how long it stays on the skin).
Particle size (0-30 microns). Boron Nitride is a natural, inert mineral and itis a useful additive to foundations, concealers, eye shadows, lipsticks, skin, creams and face and body powders.
Generally used in amounts as follows:
* Pencils 1-5%
* Face/Body Powder 5-30%
* Foundations 3-7%
