Crayola® Markers are made with six components consisting of: a color solution, a porous plastic nib, a plastic barrel, a cotton filament (ink reservoir), an end plug, and a cap. Although specific ingredient information is proprietary, most of the color solutions in Crayola Markers are made from water and dyes.

Permanent markers are made up of three components: colored pigments, a solvent (be it water, alcohol, or another solution entirely varies on a manufacturer to manufacturer basis), and a polymer. Permanent markers commonly use an acrylic polymer in their ink, which helps the marker stick to the writing surface.

In general, permanent marker ink comprises a main carrier solvent, a glyceride, a pyrrolidone, a resin, and a colorant, making it water resistant. It is capable of writing on a variety of surfaces from paper to metal to stone.

Benefits of Washable Markers They don't stain any surface permanently, making them a perfect choice for your kid's art classes at home or in the classroom. Even better, washable markers are non-toxic, so you don't have to worry about handing them over to your child.

The ink is made of color pigments, a chemical solvent and a polymer or “release agent.” The difference between dry erase markers and permanent markers is the kind of polymer used. Permanent markers use an acrylic polymer that helps the pigment stick to surfaces, while dry erase markers use an oily silicone polymer.

Chemical Properties: Washable markers use food-coloring dyes, carboxylic acids and carboxylates, as well as a water-based solvent that prevents the color from sticking to surfaces.

Permanent markers, including popular brands like Sharpie, contain ink that is made from the chemicals xylene, toluene and urethane resin. Permanent markers are safe when used as intended. Intentionally breathing in the marker fumes can be harmful.

The ink itself is made of a pigment or dye to give it a color, a resin to make it stick to a writing surface, and a solvent to make the ink move through the marker. A plastic top seals one end of the marker off, and a felt tip makes it possible to write with the other end.
