Composition
Sharpie permanent markers contain dyes, pigments and a solvent mixture of butanol, propanol, diacetone alcohol and ethanol. Additional solvents in the inks include alcohol, ketone, xylene and glycol ethers.
Effects of Ingredients
The pigments in the ink determine the marker's resistance to fading. The Sharpie company claims its particular mixture of pigments is highly effective in resisting product fading. The company claims writing produced with the Sharpie will last perhaps a few months when exposed to outdoor elements, and as long as several years in an indoor and protected environment.
Toxicity
The ingredients in a permanent marker are not considered toxic, when used according to instructions. However, they are not to be ingested or placed upon skin.
