International Chemical Safety Cards STEARIC ACID ICSC: 0568 Octadecanoic acid 1-Heptadecanecarboxylic acid Cetylacetic acid CH3(CH2)16COOH / C18H36O2 Molecular mass: 284.5 ICSC #    0568 CAS #     57-11-4 RTECS # WI2800000 April 11, 1997 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Combustible. NO open flames. Powder, water spray, foam, carbon dioxide. EXPLOSION EXPOSURE PREVENT DISPERSION OF DUST!  •INHALATION Local exhaust. Fresh air, rest.  •SKIN Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES Safety spectacles. 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. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Well closed. R: S: SEE IMPORTANT INFORMATION ON BACK ICSC: 0568 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994.

International Chemical Safety Cards STEARIC ACID ICSC: 0568 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: WHITE CRYSTALS OR POWDER , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. CHEMICAL DANGERS: OCCUPATIONAL EXPOSURE LIMITS: TLV (as stearates): ppm; 10 mg/m3 (ACGIH 1996). 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 by dispersing aerosols. EFFECTS OF SHORT-TERM EXPOSURE: EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point (decomposes): 376°C Melting point: 69-72°C Relative density (water = 1): 0.94-0.83 Solubility in water: none Vapour pressure, Pa at 174°C: 133 Flash point: 196°C Auto-ignition temperature: 395°C ENVIRONMENTAL DATA N O T E S Health effects of exposure to the substance have not been investigated.
