The whiteness of the crystals permits low micron sized powders to act as pigments. Their high surface area provides bonding sites for liquid carriers, providing excellent coverage and hiding power.
Flat platelets allow for excellent compaction eliminating the need for compacting additives such as stearates.
Scientific testing shows TRÈS BN powder offers lower coefficients of friction than traditional cosmetic powders such as talc, resulting in a more lubricious feel and silky texture.
