Is fumed silica harmless to the human body?
Fumed silica has been industrially produced since the 1940s. In the past few decades of industrial production, no cases of silicosis caused by inhalation of fumed silica have been found. The International Association for Research on Cancer (IARC) states that there is currently insufficient evidence that synthetic amorphous silica is carcinogenic to humans or experimental animals.
Fumed silica is an amorphous silica product obtained by high-temperature hydrolysis of organohalosilane in a hydrogen-oxygen flame. Its primary particle size is between 7 and 40 nanometers, its specific surface area is generally greater than loomZ/g, and its product purity is Very high, silica content not less than 99.8%
