Use

Formulators may select silicon dioxide (solum diaomeae) as an alternative to diatomaceous earth or clay, particularly when developing mineral make-up, pressed or loose powders. Silicon dioxide has abrasive, absorbent, and anti-caking properties, and can also reduce the transparency of a formulation. Silicon dioxide is the u.S. name for what is known as solum diatomeae.
