The Chemistry of Sharpies

Introduction
  • Sharpies are sold in about 20 different countries, sharpie is just another permanent marker. There’s is about 39 different colors of the fine point.

  • I choose the chemistry of sharpies because I love to draw and write with sharpies.

  • It affects how i write and I just love all the colors especially silver and the weird colors.

Main Chemicals, Compounds, Components

In a permanent parker like a sharpie the nasty smell is organic chemicals such as: xylene, and then solvent of their choice such as: alcohol, ethanol or isopropanol, ethylene glycol monobutyl. There is at least propanol, butanol, and diacetone. Therefore resin or polymer is added as a "binder" that promotes adhesion. Permchrome ink has the alcohol but not glycol ether.

  • Alcohol:  hydroxyl functional group (-O H) combines with a carbon atom, Ethanol: (C2H5OH) Isopropanol: common compound with molecular formula, C3H8O or C3H7OH, Ethylene glycol: HO+OH, ethane-1,2-diol,

  • Alcohol or ethanol or isopropanol is the solvent, it makes it smell better

  • Ethylene Glycol monobutyl evaporates quickly

Chemistry's Role

The 2 main components of the chemistry of a sharpie are made when they are mixed in together. Some of the chemicals are naturally occurring, the mixing is occurred in a lab.  If so, how do they create them.

Background Research

The original sharpie shape was the fine point, it was introduced in 1979, but sharpies really took off in 1989. The sharpie chisel tips were available in eight colors, and the twin tip in 20 different colors, and the Fine Point in 39 (plus metallic silver). The sharpie was the first permanent marker, it was made at Stanford Manufacturing Company. In 2004 sharpies came out with a new design, where you just clicked the top like a pen and it would dispense the ink and then just click the top again and it would go back in the outer shell.
