EXPOSURE & HEALTH EFFECTS
Routes of exposure Effects of short-term exposure If swallowed the substance easily enters the airways and could result in aspiration pneumonitis.	Inhalation risk A harmful contamination of the air will not or will only very slowly be reached 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.
