DIETHYLENE GLYCOL MONOBUTYL ETHER ICSC: 0788
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID

CHEMICAL DANGERS:
The substance can presumably form explosive peroxides. Reacts with strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: 100 mg/m; Peak limitation category: I(1); Pregnancy risk group: C; (DFG 2003).
INHALATION RISK:
A harmful contamination of the air will be reached 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.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin.
