International Chemical Safety Cards 2-OCTANOL ICSC: 1170 Capryl alcohol 1-Methyl-1-heptanol 2-Hydroxy-n-octane Hexylmethylcarbinol CH3(CH2)5CH(OH)CH3 / C8H18O Molecular mass: 130.3 ICSC #    1170 CAS #     123-96-6 RTECS # RH0795000 October 09, 2002 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Combustible. NO open flames. Alcohol-resistant foam, dry powder, carbon dioxide. EXPLOSION Above 76°C explosive vapour/air mixtures may be formed. Above 76°C use a closed system, ventilation, and explosion-proof electrical equipment. In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE  •INHALATION Cough. Sore throat. Ventilation, local exhaust, or breathing protection. Fresh air, rest.  •SKIN Dry skin. Protective gloves. Rinse and then wash skin with water and soap.  •EYES Redness. Pain. Safety goggles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Burning sensation. Do not eat, drink, or smoke during work. Rinse mouth. Do NOT induce vomiting. Give plenty of water to drink. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Collect leaking liquid in covered containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT let this chemical enter the environment. (Extra personal protection: filter respirator for organic gases and vapours.) Separated from strong oxidants. Ventilation along the floor.

International Chemical Safety Cards 2-OCTANOL ICSC: 1170 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS OILY LIQUID , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: Reacts with strong oxidants . OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation, through the skin and by ingestion. INHALATION RISK: No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance is irritating to the eyes and the respiratory tract and is mildly irritating to the skin . If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The liquid defats the skin. PHYSICAL PROPERTIES Boiling point: 178.5°C Melting point: -38.6°C Relative density (water = 1): 0.82 Solubility in water: none (0.096 ml/100 ml) Vapour pressure, Pa at 25°C: 32 Relative vapour density (air = 1): 4.5 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.0 Flash point: 76°C Octanol/water partition coefficient as log Pow: 2.72 ENVIRONMENTAL DATA The substance is harmful to aquatic organisms.
