International Chemical Safety Cards OLEIC ACID ICSC: 1005 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID , TURNS YELLOW TO BROWN ON EXPOSURE TO AIR. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance is a weak acid. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: INHALATION RISK: Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly on spraying. EFFECTS OF SHORT-TERM EXPOSURE: The substance is mildly irritating to the eyes and the skin . EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Decomposes below boiling point Melting point: 13.4°C Relative density (water = 1): 0.89 Solubility in water, g/100 ml: none Flash point: 189°C c.c. Auto-ignition temperature: 363°C Octanol/water partition coefficient as log Pow: 7.73 (estimated) ENVIRONMENTAL DATA N O T E S The substance can be absorbed by ingestion, but no harmful effects have been found.
