IMPORTANT DATA

Physical State; Appearance
COLOURLESS TO PALE YELLOW LIQUID

Chemical dangers
The solution in water is a weak acid.

Occupational exposure limits
TLV: (inhalable aerosol and vapor) 0.1 mg/m³ as TWA; A4 (not classifiable as a human carcinogen); SEN; (ACGIH 2003).
MAK: skin absorption (H); sensitization of skin (Sh); Carcinogen category: 3B; (DFG 2004).

Routes of exposure
The substance can be absorbed into the body by inhalation of its vapour or by inhalation of its aerosol, 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 skin.

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
