International Chemical Safety Cards ZINC STEARATE ICSC: 0987 ZINC STEARATE Octadecanoic acid, zinc salt C36H70O4Zn/Zn(C18H35O2)2 Molecular mass: 632.3 CAS # 557-05-1 RTECS # ZH5200000 ICSC # 0987 TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Powder, water spray, foam, carbon dioxide. EXPLOSION Finely dispersed particles form explosive mixtures in air. Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.   EXPOSURE PREVENT DISPERSION OF DUST! INHALATION Avoid inhalation of fine dust and mist. Fresh air, rest. Refer for medical attention. SKIN Rinse skin with plenty of water or shower. EYES Safety goggles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor. INGESTION Do not eat, drink, or smoke during work. Rinse mouth. Give plenty of water to drink. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place (extra personal protection: P1 filter respirator for inert particles).

International Chemical Safety Cards ZINC STEARATE ICSC: 0987 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: WHITE, FINE, SOFT POWDER. PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. If dry, it can be charged electrostatically by swirling, pneumatic transport, pouring, etc. CHEMICAL DANGERS: The substance decomposes on heating producing acrid smoke and fumes of zinc oxide. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV: ppm; 10 mg/m3 (ACGIH 1992-1993). ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly. EFFECTS OF SHORT-TERM EXPOSURE: EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Melting point: 130°C Relative density (water = 1): 1.1 Solubility in water: none Flash point: 277°C o.c. Auto-ignition temperature: 420°C Explosive limits, vol% in air: 30 g/m3 - ?
