 10: Stability and Reactivity Data

Stability:                                                                               The product is stable.

Instability Temperature:                                               Not available.

Conditions of Instability:                                               Excess dust generation, incompatible materials

Incompatibility with various substances: Reactive with oxidizing agents, metals.

Corrosivity:                                                                         Non-corrosive in presence of glass.

Special Remarks on Reactivity:

Hygroscopic. Sodium sulphate reacts violently with magnesium. Also incompatible with aluminium, potassium, mercury, lead, calcium, silver, barium, ammonium ions, and strontium. Sulphates give precipitates with salts of lead, barium, strontium, and calcium. Silver and mercury form slightly soluble salts. Alcohol precipitates most sulphates out of solution.

Special Remarks on Corrosivity:

The rates of corrosion of iron and steel in water are a function of the specific mineral quality as well as the alkalinity and pH values. Sodium sulphate … is a strong contributor to the rate of corrosion. For example, in water with 400 mg/l of alkalinity (as CaCO3) at pH 7, the corrosion rate will be zero at 200 mg/l of Na2SO4, but when the concentration of sodium sulphate is 400 mg/l, the corrosion rate will be about 100 mg per square cm per day.

Polymerization:                                                                 Will not occur.

11: Toxicological Information

Routes of Entry: Inhalation. Ingestion.

Toxicity to Animals: Acute oral toxicity (LD50): 5989 mg/kg [Mouse].

Chronic Effects on Humans: Not available.

Other Toxic Effects on Humans: Slightly hazardous in case of skin contact (irritant), of ingestion, of inhalation.

Special Remarks on Toxicity to Animals: Not available.

Special Remarks on Chronic Effects on Humans:

May cause adverse reproductive effects (fetotoxicity) based on animal studies. Human human data found May cause cancer (tumorigenic) based on animal studies. No human data found. Placental absorption of sulphate ion has been characterized.

Sulphate ion levels at term are somewhat higher in fetal than in maternal blood.

Special Remarks on other Toxic Effects on Humans:

Acute Potential Health Effects:

Skin: May cause irritation, although it is not known to be an irritant.

Eyes: May cause eye irritation.

Ingestion: Saline cathartics (laxatives) are poorly absorbed from the gastrointestinal tract; hence, systemic toxicity is unlikely unless massive amounts have been ingested. Ingestion of large amounts may cause gastrointestinal (digestive) tract irritation with abdominal pain, nausea, vomiting, diarrhea. Low hazard for usual industrial handling.

Inhalation: May cause respiratory tract irritation. Low hazard for usual industrial handling.
