Sodium Aluminum Silicate
Sodium aluminum silicate (sodium salt of aluminosilicic acid, aluminum sodium
silicate, aluminum sodium salt of silicic acid, sodium aluminosilicate, sodium
aluminum silicate, sodium feldspar) is a tasteless, odorless powder or beads
which is insoluble in water, alcohol, and organic solvents; it is partially
soluble in strong acids and alkali hydroxides.
Sodium aluminum silicate is used as anticaking agent in foods, desiccants,
and detergents; reinforcing filler in rubbers; extender for paints; solvent;
white pigment in paper, paints, and plastics; to remove hardness ions from fresh
water; abrasive; viscosity control agent in cosmetics and pharmaceuticals; in
coatings for paper and paperboard.
Sodium aluminum silicate is irritant to eyes and mucous membranes and is
