EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation, through the skin and by ingestion. Effects of short-term exposure	Inhalation risk No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C. Effects of long-term or repeated exposure The substance defats the skin, which may cause dryness or cracking. Animal tests show that this substance possibly causes toxicity to human reproduction or development.
