What is "Silica" and what is its usefulness?

Silica, or silice in French, is naturally present in rocks such as flint, chalcedony, amethyst, and quartz. It is also naturally present in the body. Silica is used in various fields (industrial and in cosmetology). Discover some information about silica.

What is Silica?

Silica is the INCI name for silicon dioxide, a mineral found in clay, granite, sandstone, and certain plants. It is the natural form of silicon dioxide. Belonging to the silicate family, silica is composed of more than 98% silicon dioxide. Resistant to heat, silica is insoluble in water and acids.

Silica, what is its utility?

Silica, or silice in French, is an abrasive agent that helps remove materials that settle on the surface of the body. This is why it is found in toothpastes. Silica is also used as an absorbing agent. In the form of fine particles, it absorbs water or oil. It is also used to ensure the fluidity of solid particles and thus limit their agglomeration in powders, such as those used for the face, for example.

Silica is also used as an opacifying agent, meaning it reduces transparency or translucency. Furthermore, it serves as a viscosity control agent.

In the field of cosmetology, silica is found in nail polishes, lacquers, lip inks, and even razors. Indeed, it is used to increase the temperature stability of certain lipsticks.
