Zinc Stearate MSDS Sheet, Material safety Data Sheet

1. Product Identification

Synonyms: Dibasic zinc stearate; stearic acid zinc salt; octadecanoic acid zinc salt, zinc distearate.
CAS No.: 557-05-1
Molecular Weight: 632.2
Chemical Formula: Zn(C18H35O2)2

2. Composition/Information on Ingredients

Ingredient: Zinc Stearate
Percent: 90 - 100%

3. Hazards Identification

Emergency Overview
WARNING! MAY FORM COMBUSTIBLE DUST CONCENTRATIONS IN AIR. Hazardous in case of skin contact (irritant), of eye contact (irritant), of ingestion, of inhalation.
Potential Health Effects:
Inhalation: Symptoms from excessive inhalation of dust may include coughing and difficult breathing.
Ingestion: Large dose may cause abdominal spasms and diarrhea.
Skin Contact: May cause skin irritation. Constant exposure to excessive amounts may cause eczema.
Eye Contact: May cause redness, pain.
Chronic Exposure: Grossly excessive and chronic inhalation of the dust may cause a progressive chemical pneumonitis, cyanosis, and pulmonary edema.
Aggravation of Pre-existing Conditions: Persons with pre-existing skin disorders, impaired respiratory function, or a history of pulmonary disease should not be exposed to dusts.
Repeated or prolonged exposure to Zinc stearate is not known to aggravate medical condition.

4. First Aid Measures

Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Call a physician.
Ingestion: Give several glasses of water to drink to dilute. If large amounts were swallowed, get medical advice.
Skin Contact: Wash exposed area with soap and water. Get medical advice if irritation develops.
Eye Contact: Check for and remove any contact lenses. Do not use an eye ointment. Seek medical attention.

5. Fire Fighting Measures

Fire: Flash point: 279C (534F)
Auto ignition temperature: 790C (1454F)
Minimum dust cloud ignition temperature is 690C (1274F). Contact with strong oxidizers may cause fire.
Explosion: Fine dust of Zinc stearate dispersed in air in sufficient concentrations, and in the presence of an ignition source is a potential dust explosion hazard. Minimum exposable concentration: 0.02 g/l (air). (Bureau of Mines, 1968). Maximum explosion pressure: 68 lb./sq. in. @ 0.3 ounces per cubic foot. Sensitive to static discharge.
Fire Extinguishing Media: Water spray, dry chemical, alcohol foam, or carbon dioxide. Water or foam may cause frothing.

6. Accidental Release Measures

Small Spill: Use appropriate tools to put the spilled solid in a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and dispose of according to legal requirements.
Large Spill: Use a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and allow to evacuate through the sanitary system.

7. Handling and Storage

Precautions: Keep Zinc stearate away from heat. Keep away from sources of ignition. Empty containers pose a fire risk, evaporate the residue under a fume hood. Ground all equipment containing material. Do not breathe dust. Wear suitable protective clothing In case of insufficient ventilation, wear suitable respiratory equipment. If you feel unwell, seek medical attention and show the label when possible. Avoid contact with skin and eyes.
Storage: Keep Zinc stearate container dry. Keep in a cool place. Ground all equipment containing material. Keep container tightly closed. Keep in a cool, well-ventilated place. Combustible materials should be stored away from extreme heat and away from strong oxidizing agents.

8. Exposure Controls/Personal Protection

Airborne Exposure Limits:
-OSHA Permissible Exposure Limit (PEL):
15 mg/m3 total dust, 5 mg/m3 respirable fraction for zinc stearate
-ACGIH Threshold Limit Value (TLV):
10 mg/m3 total dust for stearate (does not include stearate of toxic metals) A4 - Not classifiable as a Human Carcinogen.
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved):
If the exposure limit is exceeded and engineering controls are not feasible, a half face piece particulate respirator (NIOSH type N95 or better filters) may be worn for up to ten times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest.. A full-face piece particulate respirator (NIOSH type N100 filters) may be worn up to 50 times the exposure limit, or the maximum use concentration specified by the appropriate regulatory agency, or respirator supplier, whichever is lowest. If oil particles (e.g. lubricants, cutting fluids, glycerin, etc.) are present, use a NIOSH type R or P filter. For emergencies or instances where the exposure levels are not known, use a full-face piece positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.
Skin Protection:
Gloves and lab coat, apron or coveralls.
Eye Protection:
Use chemical safety goggles.
