Yes. Cabot's aerogel products, including Lumira™ aerogel and Enova™ aerogel, are surface-treated precipitated synthetic amorphous silica gel that is chemically very similar to other silica products. It consists of 97% treated precipitated silica amorphous silica gel and 3% water. Precipitated silica is a common product used in personal care products such as lotions and cosmetics. Cabot's aerogel products do not contain crystalline silica and are neither carcinogenic nor mutagenic.

Cabot Corporation’s aerogel manufacturing process is analagous to the commercial production of silica gel. The treated gel is dried preserving its porous structure and rendering the product hydrophobic through a patented process.

Cabot's aerogel is a highly porous structure with an average pore size of ~20 nanometers. This pore size is smaller than the mean path of air thus restricting air molecules from colliding with another. It is this feature that makes aerogel a poor conductor of heat, hence a great thermal insulator.

Aerogel has unique thermal, acoustic, optical and mechanical properties. All of these are largely a result of the pore size and pore size distribution of aerogel. Because aerogel has an average pore size of 20 nanometers it has a unique interaction with heat, sound and light.
