1 SILVER FERN CHEMICAL Safety Data Sheet SECTION 1: IDENTIFICATION Product Name: (All Grades) CAS Number: Chemical Name: Fatty acids, Zinc salts Synonyms: Zinc Soap; Fatty acids, Zinc salts; Stearic acid zinc salt; zinc octadecanoate; zinc distearate Uses: Laboratory chemicals, Manufacture of substances Company Business Contact Silver Fern Chemical, Inc. Customer Service: Queen Anne Avenue North Suite #C Seattle WA 98109, USA 24 Hour Emergency Contact Infotrac Outside USA & Canada SECTION 2: HAZARD IDENTIFICATION Warning GHS classification Physical hazards: Health hazards: Environmental hazards: OSHA defined hazards: Not classified Classification not possible Not classified Combustible dust Hazard Statement: May form combustible dust concentrations in air SECTION 3: COMPOSITION / INFORMATION ON INGREDIENTS CAS # Content (W/W) Ingredients >99% Fatty acids, Zinc salts <0.5% Free Fatty Acid Effective Date: 3/23/2015 Page 1 of 5

2 SECTION 4: FIRST AID MEASURES If inhaled: Remove to fresh air. Get medical attention for any breathing difficulty. In case of skin contact: Wash with clean water. In case of eye contact: Wash thoroughly with running clean water. Get medical advice if irritation develops. If swallowed: Seek medical advice Acute and delayed symptoms: The available information indicates that zinc stearate is generally non-toxic. High concentration of dust may cause coughing and mild temporary irritation. May be slightly irritating to eyes. First aid and notes for physicians: Zinc stearate practically is of very low toxicity SECTION 5: FIRE FIGHTING MEASURES Flash Point: 277 C (open cup) Suitable extinguishing media: Carbon dioxide, dry chemical powder, alcohol foam, water spray. Water or foam may cause frothing. Unsuitable extinguishing media: Water jet Special hazards arising from the substance or mixture: Carbon monoxide, carbon dioxide and zinc oxides Advice for firefighters: In the event of a fire, wear full protective clothing and approved self-contained breathing apparatus. Fight fire from a safe distance or a protected location. Under certain conditions, a dust cloud of zinc stearate can explode when ignited by a spark, flame or other ignition source. Must avoid generating dust to minimize risk of explosion. SECTION 6: ACCIDENTAL RELEASE MEASURES Containment: Keep unnecessary personnel away. Eliminate all sources of ignition. Do not allow the spilled product to enter sewers or open waterways. Clean-up Procedures: Dust deposits should not be allowed to accumulate on surfaces, as these may form an explosive mixture if they are released into the atmosphere in sufficient concentration. Avoid the generation of dust during the clean-up. Vacuum spills or cover with damp sand or saw-dust if sweep. Nonsparking tools should be used. SECTION 7: HANDLING AND STORAGE Handling: Open packaging bag carefully, avoid spillage and dust formation and control ignition sources. Use this product with adequate ventilation. Wash hand after handling. Storage: Store in cool, dry place to avoid the effects of heat and moisture. Keep container tightly closed and properly labeled. Avoid exposure to sunlight, heat and spark. Minimize dust generation and accumulation. Routine housekeeping should be instituted to ensure that dusts do not accumulate on surfaces. Dry powders can build static electricity charges when subjected to the friction of transfer and mixing operations. Provide adequate precautions, such as electrical grounding and bonding, or inert atmospheres. Effective Date: 3/23/2015 Page 2 of 5

3 SECTION 8: EXPOSURE CONTROLS AND PERSONAL PROTECTION Exposure Controls Exposure limit NIOSH REL: TWA 10mg/m3 (Total), TWA 5mg/m3 (Resp) OSHA PEL: TWA 15mg/m3 (Total), TWA 5mg/m3 (Resp) Engineering controls General room ventilation plus local exhaust at points of emission to maintain levels of airborne contaminants below exposure limits. It is recommended that all dust control equipment such as local exhaust ventilation and material transport systems involved in handling of this product contain explosion relief vents or explosion suppression system or an oxygen- deficient environment. Ensure that dusthandling systems (such as exhaust ducts, dust collectors, vessels, and processing equipment) are designed in a manner to prevent the escape of dust into the work area (i.e., there is no leakage from the equipment). Use only appropriately classified electrical equipment and powered industrial trucks Personal Protective Equipment (PPE) Respiratory protection: An appropriate dust respirator. Should be used as a precautionary measure where airborne contaminants may occur. Hand protection: Protective gloves Eye protection: Safety glasses or chemical safety goggles Body protection: Overall or dust cloth, change daily. SECTION 9: PHYSICAL AND CHEMICAL PROPERTIES Appearance: Fine, soft white powder, granules Odor: Slight fatty acid odor Odor threshold: Data not available ph (water slurry at 25 C) : 7 typical Melting point: C Initial boiling point and boiling range: Decompose Flash point: 277 C (open cup) Evaporation rate: Flammability: Non-flammable but combustible Lower flammable limit: 20g/m3 Vapor pressure: Solubility: Insoluble in water, alcohol and ether; soluble in benzene and in heated common solvents; decomposed by diluted acids. Vapor density: Data not available Specific gravity: at 20 C Octanol / water partition coefficient: 1.2 (As log Pow) Auto ignition temperature: 421 C Decomposition temperature: Data not available Viscosity: Molecular weight: 603 typical Effective Date: 3/23/2015 Page 3 of 5

4 SECTION 10: STABILITY AND REACTIVITY Chemical stability: Stable under normal condition of storage & transport Conditions to avoid: Incompatible materials, static charge, sparks, heat and other ignition sources, generation of dust Substances to avoid: Can react with acids, oxidizing agents and alkalies Hazardous reactions: Decomposed by acids, oxidizing agents and alkalies Decomposition products: Carbon monoxide, carbon dioxide and zinc oxide fume SECTION 11: TOXICOLOGICAL INFORMATION Routes of exposure: Can occur through inhalation, ingestion and eye or skin contact. Acute health effects Eye contact: Dust or mist may be slightly irritating. Minimal to no irritation seen in an animal study. Skin contact: Probably not irritating and not absorbed. Inhalation: High concentration of dust may cause coughing and mild temporary irritation. Ingestion: Oral toxicity is low. Rat LD50 > 5000mg/kg (reference source: EU-RAR (2004)) Chronic health effects: Long term exposures to high concentration of dust may cause increased mucous flow in the nose and respiratory system airways. This condition usually disappears after exposure ceases. Carcinogenicity: No information available. Reproductive toxicity: No information available. Mutagenicity: No information available. SECTION 12: ECOLOGICAL INFORMATION Aquatic and terrestrial Ecotoxicity: No information available Persistence and degradability: Not expected to bioaccumulate, knowing that fatty acids will degrade by the Beta oxidation pathway Bioaccumulation: Not expected to bioaccumulate. Mobility in soil: No information available The product should be prevented from entering drains, sewers, streams etc. SECTION 13: DISPOSAL CONSIDERATIONS Disposal method: Dispose of waste in accordance with local regulations and acts. Contaminated packaging must be treated in the same manner as the product itself. Precautions for disposal: Prevent material from entering drains, sewers, streams etc. SECTION 14: TRANSPORT INFORMATION DOT (US) IMDG Effective Date: 3/23/2015 Page 4 of 5
