“There are no warning labels on Sharpie markers. However, they bear the new AP (Approved Product) certification symbol of The Art & Creative Materials Institute, Inc. (ACMI). According to the organization:

“The new AP (Approved Product) Seal, with or without Performance Certification, identifies art materials that are safe and that are certified in a toxicological evaluation by a medical expert to contain no materials in sufficient quantities to be toxic or injurious to humans, including children, or to cause acute or chronic health problems. This seal is currently replacing the previous non-toxic seals: CP (Certified Product), AP (Approved Product), and HL Health Label (Non-Toxic) over a 10-year phase-in period. Such products are certified by ACMI to be labeled in accordance with the chronic hazard labeling standard, ASTM D 4236, and the U. S. Labeling of Hazardous Art Materials Act (LHAMA).” ^[5]

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.^[6] 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,^{[citation needed]}n-butanol,^[7][8][9]diacetone alcohol,^[10], and cresol.^[11][12] 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 do 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 conditions.

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.”

basically.. understand that doing this DOES have un-evaluated risks…
