CI 77000, also known as Alumina, Silver Dye, Aluminum oxide, Aluminum, Aluminia corundum or Aluminum powder, is an industrial chemical product that is produced from aluminium ore. This mineral has many applications in various industries due to its unique properties such as its high melting point, chemical stability, corrosion resistance, hardness and ability to withstand weathering.

One of the most common uses of alumina is as a dye. Especially as a silver dye, it is widely used in the cosmetic industry. For example, it is used in nail polish, make-up or eye shadow for its ability to reflect and diffuse light, giving products an attractive glossy appearance. Due to its fine powdery state, it can also be used as an abrasive ingredient in some cleaning products. Alumina's absorbent properties are also used in some deodorants and antiperspirants. In the construction and ceramics industries, this mineral is often used for the production of enamel tiles, glass and ceramic products. Alumina corundum, a form of alumina, is a popular ingredient in sandpaper and discs.
