Super Sparkle White Diamonds Mica Powder is a glittering cosmetic that is safe for general, eye, lip and nail polish cosmetics. It is blended with biodegradable glitter for an outstanding performance effect. This mica has a large particle size making this powder sparkle. It looks like diamonds as the light glistens off the mica. We recommend pouring your MP soap at a low temperature to ensure the mica stays suspended.
