ProMinent DULCOMETER PH-501 Assembly And Operating Instructions Manual page 264

Soluble in hot water, glycerol. Partially soluble in cold water. Insoluble in acetone, alcohol.
Section 10: Stability and Reactivity Data
Stability: The product is stable.
Instability Temperature: Not available.
Conditions of Instability: Incompatible materials, moisture
Incompatibility with various substances:
Reactive with acids. Slightly reactive to reactive with moisture.
Corrosivity: Non-corrosive in presence of glass.
Special Remarks on Reactivity:
Hygroscopic. Combines with water with evolution of heat. Incompatible with phosphorus pentoxide, lithium, fluorine, fluoride,
ammonia + silver nitrate, 2,4,6-trinitrotoluene, ammonia, acids, sodium sulfide + water, hydrogen peroxide, red hot alumium
metal, sodium sulfide, zinc, calcium hydroxide. Sodium Carbonate is decomposed by acids with effervescence. Reacts
violently with F2, Lithium, and 2,4,6-trinitrotoluene. Sodium begins to decompose at 400 C to evolve CO2.
Special Remarks on Corrosivity: Hot concentrated solutions of sodium carbonate are mildly corrosive to steel.
Polymerization: Will not occur.
Section 11: Toxicological Information
Routes of Entry: Inhalation. Ingestion.
Toxicity to Animals:
WARNING: THE LC50 VALUES HEREUNDER ARE ESTIMATED ON THE BASIS OF A 4-HOUR EXPOSURE. Acute oral
toxicity (LD50): 4090 mg/kg [Rat]. Acute toxicity of the dust (LC50): 1200 mg/m3 2 hours [Mouse].
Chronic Effects on Humans: May cause damage to the following organs: upper respiratory tract, skin, eyes.
Other Toxic Effects on Humans: Hazardous in case of skin contact (irritant), of ingestion, of inhalation (lung irritant).
Special Remarks on Toxicity to Animals: LDL (Lowest Published Lethal Dose) [Man] - Route: Oral; Dose: 714 mg/kg
Special Remarks on Chronic Effects on Humans: May cause adverse reproductive effects based on animal test data
Special Remarks on other Toxic Effects on Humans:
Acute Potential Health Effects: Skin: Causes skin irritation with possible burns depending on the concentration, site (abraded
or intact skin), and duration of exposure. Eyes: Causes eye irritation and possible burns. Concentrated solutions may cause
permanent corneal injury (permanent corneal opacity). Ingestion: Sodium carbonate ingestion may cause irritation of the
digestive tract resulting in nausea, vomiting, diarrhea, thirst, abdominal pain depending on concentration and amount ingested.
May also affect the cardiovascular system . Inhalation: Dust may cause respiratory tract and mucous membrane irritation
with coughing and shortness of breath (dyspnea), pulmonary edema. Chronic Potential Health Effects: Chronic inhalation
may result in decreased pulmonary function, nasal congestion, nosebleeds, perforation of the nasal septum. Other effects
of chronic exposure are skin (dermatitis and ulceration), and gastrointestinal complaints. However, the effects of chronic
exposure seem to be reversible if exposure is decreased.
Section 12: Ecological Information
Ecotoxicity: Not available.
BOD5 and COD: Not available.
Products of Biodegradation:
Possibly hazardous short term degradation products are not likely. However, long term degradation products may arise.
