1-VINYL-2-PYRROLIDONE

ICSC: 1478

IMPORTANT DATA

PHYSICAL STATE; APPEARANCE:
COLOURLESS TO YELLOW LIQUID

CHEMICAL DANGERS:
The substance may polymerize in the presence of air due to warming, under the influence of light and acid(s). The substance decomposes on burning producing toxic and corrosive gases (nitrogen oxides).

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.05 ppm as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2004).
MAK: skin absorption (H); Carcinogen category: 2; (DFG 2004).

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 will be reached quickly on evaporation of this substance at 20°C.

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

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the liver, resulting in liver impairment. Tumours have been detected in experimental animals but may not be relevant to humans.
