Use
Saponite is a natural clay mineral that is not acutely toxic; therefore,
no toxicity values have been established. However, it may contain
small amounts of crystalline silica in the form of quartz. Chronic
exposure to crystalline silica can have adverse effects on the
respiratory system. EU labeling states the material is not classified as
dangerous.
Saponite dust can be irritating to the respiratory tract and eyes.
Contact with this material may cause drying of the skin.
