Sodium aluminosilicate is a fine white powder. Many ordinary rocks (feldspars) are aluminosilicates. Aluminosilicates with more open three-dimensional structures than the feldspars are called zeolites. The openings in zeolites appear as polyhedral cavities connected by tunnels. Zeolites act as catalysts by absorbing small molecules in their interior cavities and holding them in proximity so that reaction among them occurs sooner.

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

SMALL SPILLS AND LEAKAGE: If a spill of this chemical occurs, FIRST REMOVE ALL SOURCES OF IGNITION, then you should dampen the solid spill material with acetone and transfer the dampened material to a suitable container. Use absorbent paper dampened with acetone to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with acetone followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.

RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)

NAAL SILICATES HAD VERY LOW TOXICITY TO ALGAE, MICROORGANISMS, DAPHNIA, FISH, TUBIFLEX, & MUSSELS EVEN @ VERY HIGH CONCN OF 250 MG/L HAD NO ACUTE TOXIC EFFECT ON ANIMALS.

Sodium aluminosilicate (SAS) was tested for mutagenicity in the Salmonella/microsome preincubation assay using a protocol approved by contractor of the National Toxicology Program. SAS was tested over a wide range of doses (0, 100, 333, 1000, 3333, and 4,000 ug/plate) in four Salmonella typhimurium strains (TA98, TA100, TA1535, and TA1537) in the presence and absence of Aroclor-induced rat or hamster liver S9. SAS was negative in these tests and the highest ineffective dose level tested (not causing the formation of a precipitate) in any Salmonella tester strain was 1000 ug/plate.

RATIOS OF OBSERVED NO-EFFECT CONCN OF ZEOLITE ON AQUATIC LIFE TO SURFACE WATER CONCN RANGE FROM >250->1000, INDICATING THAT THE PROPOSED USE AS A MONOPHOSPHATE BUILDER FOR DETERGENTS WOULD RESULT IN NO SIGNIFICANT ENVIRONMENTAL IMPACT AT EXPECTED USAGE LEVELS.
