EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation. Effects of short-term exposure The substance is irritating to the eyes. The substance may cause effects on the central nervous system.	Inhalation risk A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster. Effects of long-term or repeated exposure The substance defats the skin, which may cause dryness or cracking.
