Common Name(s): Hexagonal boron nitride,bn,white graphite

DESCRIPTION

What It Does: Provides the softest powder feel and best soft-focus diffusion from hexagonal boron nitride.

Why It's Used: The silkiest cosmetic powder ingredient – boron nitride's lowest-friction coefficient provides an unmatched velvety powder feel while providing excellent soft-focus optical diffusion.

How It Works: Hexagonal bn (graphite-like layered structure) provides: (1) lowest coefficient of friction of any cosmetic powder from atomic-layer slip; (2) soft-focus via light diffusion through platelets; (3) oil absorption in inter-layer spaces. optically white from wide band gap (>6 ev).

Typically Found In: Premium foundations,setting powders,luxury cosmetics

SCIENTIFIC NOTE

Boron nitride's 'white graphite' structural analogy is precise: b and n alternating in hexagonal rings provide the same layered structure as carbon in graphite, with the same excellent lubrication from inter-layer slip. the b-n bond's slight polarity (vs c-c's non-polarity in graphite) increases inter-layer electrostatic interaction slightly, making bn slightly less lubricating than graphite per layer but significantly more lubricating than any mineral oxide powder.
