Is the perlite microsphere toxic?

No, the SIL-CELL® perlite microsphere is a naturally safe material. It is inert, inorganic, and has no known toxicity. It contains no solvents, volatile organic compounds (VOCs), or harsh chemical additives.

It is chemically neutral, meaning it does not interact with other components in your formulations, even the most sensitive ones. Its neutral pH ensures optimal compatibility with most organic, mineral, or polymer matrices.

No harmful emissions are generated during storage, handling, or integration. It can be used in demanding environments, including food (excluding direct contact), cosmetics, or medical applications, depending on the context.
