Dimethicone is a silicone, derived from silica. Silica is commonly found in sand, as well as plants like bamboo. Now, even though dimethicone comes from a natural source, the process of making it requires significant chemical processing. As a result, dimethicone is considered synthetic. Having said that, dimethicone doesnt appear to be toxic.

May 20, 2020 Sources of Silica Sand SiO2 is the chemical sign of silica and it is actually the group of minerals which is a mixture of Oxygen and Silicon. This sand is often got in the crystalline state and because of weathering, plankton fossilization takes place and that results in crystallizing SiO2. In most regions of the world, these are found as mines and it is obtained in high hardness.
Pyrogenic silica is also used as a thick - ening additive in adhesives for the rotor blades of wind generators. This outstanding versatility is the result of silicone chemistry silicones are modern synthetic products based on a raw material, quartz sand, which is avail - able in practically unlimited quantities.
