1-DECANETHIOL ICSC: 0035
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
The substance decomposes on burning producing highly toxic gases including sulfur dioxide (see ICSC 0074). Reacts with strong oxidants and strong bases.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK 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 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the skin, and the respiratory tract. The substance may cause effects on the central nervous system, resulting in respiratory failure.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis.
PHYSICAL PROPERTIES
Boiling point: 241C
Melting point: -26C
Relative density (water = 1): 0.84
Solubility in water: none

Explosive limits, vol% in air: see Notes
ENVIRONMENTAL DATA

NOTES
Flash point and auto-ignition temperature are unknown in literature. Explosive limits are unknown in literature, although the substance is combustible. Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
