International Chemical Safety Cards DIBUTYL PHTHALATE ICSC: 0036 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS TO YELLOW VISCOUS LIQUID , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: As a result of flow, agitation, etc., electrostatic charges can be generated. CHEMICAL DANGERS: The substance decomposes on burning producing toxic and irritating fumes (phthalic anhydride, ICSC 0315). Reacts with strong oxidants. OCCUPATIONAL EXPOSURE LIMITS: TLV: 5 mg/m³ as TWA (ACGIH 2001). OSHA PEL: TWA 5 mg/m3 NIOSH REL: TWA 5 mg/m3 NIOSH IDLH: 4000 mg/m3 ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol and by ingestion . INHALATION RISK: A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Animal tests show that this substance possibly causes toxicity to human reproduction or development. PHYSICAL PROPERTIES Boiling point: 340°C Melting point: -35°C Relative density (water = 1): 1.05 Solubility in water, g/100 ml at 25°C: 0.001 Vapour pressure, kPa at 20°C: < 0.01 Relative vapour density (air = 1): 9.58 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.00 Flash point: 157°C c.c. Auto-ignition temperature: 402°C Explosive limits, vol% in air: 0.5 (at 235°C) to about 2.5 Octanol/water partition coefficient as log Pow: 4.72 ENVIRONMENTAL DATA The substance is toxic to aquatic organisms.
