They are considered non-toxic for “normal uses,” meaning writing on posters, soccer balls, and such. However, they are not meant for use on skin or fingernails. It might take over an ounce of ink from a Sharpie to cause a lethal reaction, and if a Sharpie is used on the skin it generally won’t cause an immediate or obvious health effect. However, according to the manufacturer’s Safety Data Sheets (MSDS), various Sharpies contain: n-propanol, n-butanol, diacetone alcohol and cresol. The first of these, n-propanol, is commonly used in cosmetics. The other three, however, are industrial solvents, chemicals that should not be sniffed, eaten, or put on the skin. As solvents, they penetrate the skin and fingernails and can enter the bloodstream.
Magnum Sharpie, King Size Sharpie, and Touch-up Sharpie products contain xylene. The Magnum and King Size Sharpies also contain cresol. However, all other products in the Sharpie line do not contain either of these chemicals, and are considered safe under "normal use".
These chemicals are not tested for human consumption, only incidental environmental exposure. So the chemical manufacturers’ technical data sheets on these chemicals are ambiguous with respect to how much should be considered a hazardous dosage, but do warn of kidney, liver, and brain damage, other nervous disorders, and DNA effects resulting in birth defects. OSHA has set permissible exposure limits (PEL) at 100ppm for n-butanol, 50ppm for diacetone alcohol, and 5ppm for cresol.
Some products that can be used to remove ink from the skin are rubbing alcohol, denatured alcohol, hand sanitizer, sunscreen lotion, nail polish remover, shaving cream, and facial cleaning pads, and also toothpaste.[7] Tabasco sauce or any Vinegar based product are also particularly effective at removing the ink from skin. However, the ink wears off on its own within two days or so, since the ink is on skin cells that are constantly being shed.
