The Environmental Protection Agency (EPA) states that the acute toxicity of n-propanol through cutaneous, oral, or inhalation modes of exposure is minimal. Like most other alcohols, n-butanol is flammable, corrosive, and generally regarded as toxic.
Although not harmful, acetone diacetyl is a well-known irritant. Additionally a potent cutaneous irritant, research on animals have shown that prolonged exposure to cresol can cause issues with the liver, kidneys, and blood.
Xylene can harm other organs and is neurotoxic. It poses a risk through ingestion, absorption through the skin, and contact with mucous membranes.
Therefore, I don't think ink pens and markers are the way to go if using them on skin, I'm not sure if they are safe, I wouldn't just to stay safe.
