Silicon dioxide / Silica (7631-86-9) O2Si
Silica is known as silicone dioxide. Silica has a variety of applications: to control a product's viscosity, add bulk, and reduce a formulation's transparency. It can also function as an abrasive. In addition, it can act as a carrier for emollients, and may be used to improve a formulation's skin feel. Spherical silica is porous and highly absorbent, with absorption capabilities roughly 1.5 times its weight. A typical claim associated with silica is oil control. It is found in sunscreens, scrubs, and wide range of other skin care, makeup, and hair care preparations. It has been successfully used in hypoallergenic and allergy-tested formulations.
