Toluene can be found in some paint removers and is also used as a thinning agent for some paints. Generally, concentrations of toluene in commercial products are not sufficient to produce dangerous exposures in most restoration-related activities. Nevertheless, it's presence can be damaging, especially in combination with other solvents. Acute exposures to toluene can produce skin and respiratory irritation, central-nervous-system depression (e.g., drowsiness), and intense headaches. Chronic exposure may be damaging to the liver and kidneys. Toluene enters the body via inhalation of vapors and absorption through the skin.
