2-ETHYLHEXANOIC ACID ICSC: 0477
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
The substance is a strong reducing agent and reacts with oxidants. The substance decomposes on heating producing irritating fumes.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (Inhalable aerosol and vapor) 5 mg/m as TWA; (ACGIH 2005).
MAK: IIb (not established but data is available) (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion.

INHALATION RISK:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20C; on spraying or dispersing, however, much faster.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes, the skin and the respiratory tract.

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

Relative density of the vapour/air-mixture at 20C (air = 1): 1.00
Flash point: 118C o.c.
Auto-ignition temperature: 371C
Explosive limits, vol% in air: 0.8-6
Octanol/water partition coefficient as log Pow: 2.64
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms.
