DIBUTYL PHTHALATE ICSC: 0036
IMPORTANT DATA
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/m as TWA (ACGIH 2001).
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 20C.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Animal tests show that this substance possibly causes toxicity to human reproduction or development.

Melting point: -35C
Relative density (water = 1): 1.05
Solubility in water, g/100 ml at 25C: 0.001
Vapour pressure, kPa at 20C: < 0.01
Relative vapour density (air = 1): 9.58
Relative density of the vapour/air-mixture at 20C (air = 1): 1.00
Flash point: 157C c.c.
Auto-ignition temperature: 402C
Explosive limits, vol% in air: 0.5 (at 235C) to about 2.5
Octanol/water partition coefficient as log Pow: 4.72
ENVIRONMENTAL DATA
The substance is toxic to aquatic organisms.
