3-CHLORO-1,2-PROPANEDIOL (RACEMIC MIXTURE) ICSC: 1664
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS TO PALE YELLOW HYGROSCOPIC LIQUID

CHEMICAL DANGERS:
The substance decomposes on heating or on burning producing toxic fumes including hydrogen chloride (see ICSC0163). Reacts with strong oxidants causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: IIb (not established but data is available) (DFG 2008).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

INHALATION RISK:
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes and the respiratory tract. The substance may cause effects on the central nervous system.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the kidneys , resulting in kidney impairment. Tumours have been detected in experimental animals but may not be relevant to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development.
