So, what is hydrated silica?

Hydrated silica is naturally derived from silicon dioxide, this compound can be found in abundance on the Earth's outer surface.

How is Hydrated Silica made?

Silica is crystalline as it occurs naturally all over the planet, sand and obsidian are some more common forms. The sand is heated along with sodium carbonate and dissolved in water to form liquid sodium silicate. 

The liquid sodium silicate is mixed with acid and precipitated to make hydrated silica, which is an odorless, tasteless white powder. The hydrated silica is then milled in the United States, and based on the particle size of the material, can be used for a variety of different applications.

Is Hydrated Silica safe?

Hydrated silica has a long history of safe use as an ingredient in food products. It is listed by the U.S. Food & Drug Administration (FDA) to be Generally Recognized As Safe (GRAS).

How Hydrated Silica used?

We use our hydrated silica as part of our non-toxic natural flame retardant system due to its lack of chemicals.

Is your Natural Hydrated Silica made in a facility that also produces crystalline silica?

No, the natural hydrated silica we use is manufactured in a U.S. facility that does not produce crystalline silica in any capacity.
