A mineral derived from the metal ore known as aluminum. It is commonly used as an abrasive and also acts as a thickening viscosity controlling agent (and thus as a bulking agent). Alumina is also a great opacifier.

Overview
Alumina is the shortened term for aluminum oxide, a mineral derived from the metal ore known as aluminum.
This white powder is commonly used as an abrasive, which means it would have applications in exfoliating skincare products.
In addition, alumina can act as a thickening viscosity controlling agent, and thus, as a bulking agent, as well. It can also serve as an anti-caking ingredient because it can absorb moisture that would otherwise cause a product to clump up.
Finally, alumina is a great opacifier, and it is often paired with titanium dioxide for the purpose of producing a bright white appearance to skincare products.
