10. Stability and Reactivity
Conditions To Avoid: Contact with acids, except under controlled conditions.
Stability: Stable
Polymerization: Will Not Occure
Incompatible Materials: Reacts with acids with release of large volumes of carbon dioxide gas and heat
Hazardous Decomposition Products: Heated to decomposition, it emits carbon dioxide
Materials To Avoid: Aluminum acids, fluorine, lithium, and 2,4,6-trinitrolouene. Simultaneous exposure
of soda ash and lime dust will form caustic soda (NaOH).
Other Precautions: When dissolving, add to water cautiously and with stirring; solutions can get hot.
11. Toxicological Information
Eye Effects: Severe irritant (50 mg, rabbit)
Skin Effects: Non-irritating to intact skin. Minor irritation may occur on abraded skin.
Dermal: Mild irritant (500 mg/24 h, rabbit).
Oral LD

: 4,090 mg/kg (rat)
Inhalation: LC50: 2.3 mg/l (2 h) (rat)
Sensitization: 0.25% sodium carbonate: non-sensitizing (human)
Target Organs: Eyes
Acute Effects from Overexposure: May cause severe irritation of the eyes, including corneal opacities. Dusts
and mists may be irritating to the skin, mucous membranes and upper respiratory tract. Although low in toxicity,
ingestion may cause nausea, vomiting, stomachache, and diarrhea. No significant acute toxicological effects
expected.
Chronic Toxicity: Excessive contact may produce “soda ulcers” on hands and perforation of the nasal septum.
Sensitivity reactions may occur from prolonged and repeated exposure.
This product does not contain any substances that are considered by OSHA, NTP, IARC or ACGIH to be “probable”
or “suspected” human carcinogens.
