IMPORTANT DATA
Physical State; Appearance ODOURLESS GRANULES OR POWDER IN VARIABLE COLOUR. Chemical dangers The substance is a weak base in suspension in water. Occupational exposure limits TLV not established.	Routes of exposure The substance can be absorbed into the body by inhalation of dust. Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly. Effects of long-term or repeated exposure The substance may have effects on the lungs, resulting in silicosis due to the presence of crystalline silica (see ICSC 0808).

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Relative density (water = 1): 2.5 Solubility in water: none

NOTES

Bentonites are aluminate silicate and can contain crystalline silica. The content varies widely from less than 1% to about 24%.
