Ballpoint pen ink is about 40 percent oil-based dye. An ink in its supply form is a liquid but after application it is required to change to a solid. The paste-like ink is smooth flowing, non-smearing and quick-drying. A professional who mixes his or her own ink from dry pigments will be most likely to know the composition of the inks. The conversion to pyrite and its subsequently loosening can lead to a loss of clarity in the documents. Pigments and tattoo inks are not regulated by the U.S. Food and Drug Administration (FDA.)

This change of state is referred to as ink drying and the varnish in the ink is responsible for this process.

It is designed to wet the pigment, which facilitates the dispersion of its particles. The chemical composition of the ink-vinegar stain is not stated by [11,13], although a key component is vinegar or acetic acid (CH 3 COOH). The composition of black tattoo pigments are Iron Oxide(Fe3O4), Iron Oxide(FeO), Carbon, and Logwood. They are composed of pigments that are suspended in a carrier solution. One or more pigments are mixed in inks, but all of them have carriers. Binder – constitutes from 15 to 50% of the composition of the ink. Inks are liquids or pastes that contain dyes or pigments, and they are used for writing pens, printing, and tattoos. It's like asking what is the chemical formula of dirt. It is the adhesive that determines the printing properties of the ink, as well as the way it binds with the substrate. However, the FDA is examining tattoo inks to determine the chemical composition of the inks, learn how they react and break down in the body, how light and magnetism react with inks, and whether there are short- and long-term health hazards associated with ink formulations or methods of applying … This has resulted in printing being used on many different surfaces ranging from aluminium can and plastic bottles through to paper. you are writing on. … Felt-tip pen inks are extremely sensitive to degradation and especially exposure to light may cause chromatic changes and fading.
