Which solvent used for Ninhydrin solutions causes the most damage to inks?

Acetone is recognized as a solvent that can cause significant damage to inks when used in Ninhydrin solutions. This is due to its strong solvent properties, which allow it to effectively dissolve various substances, including certain inks found in pens and printers. When inks are exposed to acetone, they can lose their integrity, leading to smudging, fading, or complete dissolution of the printed or written material.

In contrast, other solvents such as Freon 113, Ethyl Ether, and Petroleum Ether may not have the same aggressive effect on inks. While they can also act as solvents, they are generally less damaging to the chemical composition of inks. This distinction makes acetone the solvent of choice to be cautious with in applications involving inks, as it substantially alters or destroys the evidence being examined, which is crucial in forensic analysis and latent print development.
