Ingredient: Zinc Sulfate Monohydrate or Zinc Sulphate Monohydrate
CAS Number: 7446-19-7
EINECS EC Number: 231-793-3
Weight%: 98%-100%
Trade Names and Synonyms
: Zinc Sulfate or Zinc Sulphate, ZnSO4.H20, Hydrated Zinc Sulfate.


Eye Contact: Do not allow victim to rub eye (s). Let the eye (s) water naturally for a few minutes. If particle/dust does not dislodge, flush with lukewarm, gently flowing water for 5 minutes or until particle/dust is removed, while holding eyelid (s) open. If irritation persists, obtain medical attention. DO NOT attempt to manually remove anything stuck to the eye.
Skin Contact: Remove contaminated clothing, shoes and leather goods (e.g. watchbands, belts). Quickly and gently blot or brush away excess chemical. Wash gently and thoroughly with lukewarm gently flowing water and non-abrasive soap for 5 minutes. If irritation persists, repeat flushing. Obtain medical advice. Completely decontaminate clothing, shoes and leather goods before reuse or else discard.
Inhalation: If symptoms are experienced, remove source of contamination or move victim to fresh air. Obtain medical advice.
Ingestion: Never give anything by mouth if victim is rapidly losing consciousness, or is unconscious or convulsing. Have victim rinse mouth thoroughly with water. DO NOT INDUCE VOMITING. Have victim drink 2 – 8 oz. (60 – 240 ml) of water. Zinc sulfate is an emetic and may cause vomiting. If vomiting occurs naturally, have victim rinse mouth with water again. Obtain medical advice and bring a copy of this MSDS.


Fire and Explosion Hazards: It does not burn or support combustion.
Extinguishing Media: Use any means of extinction appropriate for the surrounding fire conditions such as water spray, carbon dioxide, dry chemical, or foam.
Fire Fighting: Toxic fumes of sulfur dioxide may result from combustion. As with any fire, fire fighters should be fully trained and wear full protective clothing including an approved, self-contained breathing apparatus which supplies a positive air pressure within a full face piece mask. Do not use water directly on material. Do not allow water run-off to enter sewers or watercourses.
Flashpoint and Method: Not Applicable.
Upper and Lower Flammable Limit: Not Applicable.
Auto ignition Temperature: Not Applicable.


Procedures for Cleanup: Stop release if possible to do so safely. Contain spill, isolate hazard area, and deny entry. Sweep up or vacuum. Place contaminated material in suitable, labeled containers for final disposal. Dispose of waste material consistent with the requirements of waste disposal authorities.
Personal Precautions: Gloves and coveralls or other protective clothing are recommended for persons responding to an accidental release. Close-fitting safety goggles may be necessary in some circumstances to prevent eye contact.
Environmental Precautions: This product can pose a threat to the environment. Contamination of soil and water should be prevented. Keep spillage and runoff from storage areas from entering soil, streams or sewers.


Store in cool, dry, well-ventilated area away from incompatible substances. Protect from physical damage. It is good practice to keep  Zinc Sulphate container closed when not in use. Avoid generating dust and the release of dust into the workplace. Good housekeeping is important to prevent accumulations of dust. Always practice good personal hygiene. Refrain from eating, drinking, or smoking in work areas.


Protective Clothing: The hazard potential is low. Where there is large scale use of this material and significant potential for worker contact, gloves and long sleeved work clothes or disposable coveralls may be necessary. Eye protection should be worn where dust is generated and there is a potential that eye contact may occur.
Ventilation: Use adequate local or general ventilation where necessary to maintain the concentrations of dust well below the recommended occupational exposure limits for general Particulates, Not Otherwise Specified (PNOS).
Respirators: Where dust or fumes are generated and cannot be controlled to within acceptable levels by engineering means, use appropriate NIOSH-approved respiratory protection equipment (a 42CFR84 Class N, R or P-95 particulate filter cartridge).


Appearance: It is colorless, odorless granules or powder
Odor: None for Zinc Sulphate
Physical State: Solid
pH: 4 to 6 @ 10% solution
Vapor Pressure: Negligible @ 20C
Freezing/Melting Point/Range: Loses water at 238°C; Decomposes at 680C (1256F)
Specific Gravity: 3.28 for heptahydrate
Coefficient of Water/Oil Distribution: Log p (oct) = -0.07 (estimated)
Solubility in Water: Soluble in water. Aqueous solutions are acidic.


Stability and Reactivity: Zinc Sulphate is stable and not considered reactive under normal temperatures and pressures. Hazardous polymerization or runaway reactions will not occur.
Incompatibilities: None have been identified to date. Avoid excessive heating that may lead to decomposition of the material.
Hazardous Decomposition Products: High temperature operations such as oxy-acetylene cutting, electric arc welding or severe overheating will generate zinc oxide fume which, on inhalation in sufficient quantity, can produce metal fume fever. Under such conditions, sulfur dioxide will also be generated and can cause respiratory distress.


Acute Toxicity (Oral LD50): > 574 mg/kg Rat
Acute Toxicity (Dermal LD50): > 2000 mg/kg Rat
General: In the form in which Zinc Sulphate is sold it is relatively non-toxic. The major route of exposure would be through the generation and inhalation of airborne dust and especially the generation of zinc oxide fume through thermal decomposition.
Skin/Eye: Zinc Sulfate direct contact may cause local irritation of the eyes or skin but would not cause tissue damage. Eye contact with solutions (>1%) may cause the appearance of white flecks on the lens of the eye. Dust or fume from burning or welding operations may also cause local irritation.
Inhalation: Zinc Sulphate acute inhalation may result in irritation but is not expected to cause significant harmful effects. Symptoms may include discomfort, coughing, tingling sensation, sneezing and/or shortness of breath and wheezing. Extreme heating of Zinc Sulphate monohydrate will generate zinc oxide fume. If inhaled, this fume can result in the condition called metal fume fever. The symptoms of metal fume fever will occur within 3 to 10 hours of exposure, and include immediate dryness and irritation of the throat, tightness of the chest, and coughing which may later be followed by flu-like symptoms of fever, malaise, perspiration, frontal headache, muscle cramps, low back pain, occasionally blurred vision, nausea, and vomiting. The symptoms are temporary and generally disappear, without medical intervention, within 24 to 48 hours of onset. There are no recognized complications, after affects, or chronic affects that result from this condition.
Ingestion: Zinc Sulfate ingestion of large doses can cause anemia and stomach symptoms. It is very astringent, and when ingested in excessive quantities, can irritate the stomach, resulting in abdominal pain, nausea, diarrhea and spontaneous vomiting.
Chronic: In general, zinc is considered to be a low toxicity metal. Zinc is a very important trace element for humans and the body regulates the amount of zinc stored by decreasing absorption and increasing excretion when intake is increased. Industrial experience has not identified any significant chronic effects from zinc sulfate to date. The item is not listed as a carcinogen by the Occupational Safety and Health Administration (OSHA), the National Toxicology Program (NTP), the International Agency for Research on Cancer (IARC), the American Conference of Governmental Industrial Hygienists (ACGIH) or the European Union (EU).
Carcinogenicity: IARC: No component of this product present at levels greater than or equal to 0.1% is identified as probable, possible or confirmed human carcinogen by IARC.


Eco toxicological data:
LC50 24 hours fish (rainbow trout) 1.24 mg/l
LC50 48 hours fish (rainbow trout) 2.4 - 5 mg/l
LC50 96 hours fish (rainbow trout) 0.24 - 0.83 mg/l
LC50 96 hours Daphnia 7.4 mg/l
Zinc Sulphate has high water solubility and its zinc and manganese contents are directly bio available. The zinc in particular may be toxic to aquatic organisms, especially fish, with water hardness, pH and dissolved organic carbon levels being regulating factors. In terrestrial systems, the mobility of zinc and manganese in soil and their degree of bioaccumulation in organisms is dependent on soil chemical conditions.


Do not wash the material down drain. Put uncontaminated material back into the process if at all possible.

Place contaminated material in suitable, labeled containers for disposal. Dispose of waste material consistent with the requirements of waste disposal authorities.
