Gel pens. Compared to other inks, gel ink has higher melting point viscosity, which supports a higher proportion of pigments in the medium.The pigments are typically copper phthalocyanine, carbon black and iron oxides, and the gel is made up of water and biopolymers, such as xanthan gum and tragacanth gum, as well as some types of polyacrylate thickeners.

Close up of an extra fine roller ball pen next to something written with it. There are two main types of roller ball pens: liquid-ink pens and gel-ink pens.The "liquid-ink" type uses an ink and ink-supply system similar to a fountain pen, and they are designed to combine the convenience of a ballpoint pen with the smooth "wet ink" effect of a fountain pen.
Some ballpoint pens use a hybrid ink formulation whose viscosity is lower than that of standard ballpoint ink, but greater than rollerball ink. [45] The ink dries faster than a gel pen to prevent smearing when writing. These pens are better suited for left-handed persons. Examples are the Zebra Surari, Uni-ball Jetstream and Pilot Acroball ...
Papain is the main ingredient of Papacarie, a gel used for chemomechanical dental caries removal. It does not require drilling and does not interfere in the bond strength of restorative materials to dentin. [13] Papain has been known to interfere with urine drug tests for cannabinoids. [14] It is found in some drug detox products.
A fountain pen is a writing instrument that uses a metal nib to apply water-based ink, or special pigment ink—suitable for fountain pens—to paper.It is distinguished from earlier dip pens by using an internal reservoir to hold ink, eliminating the need to repeatedly dip the pen in an inkwell during use.
