Elemicin is a constituent of the oleoresin and the essential oil of Canarium luzonicum (also referred to as elemi). Elemicin is named after this tree. One study found it to compose 2.4% of the fresh essential oil. [1] Elemicin is also present in the oils of the spices nutmeg and mace, with it composing 2.4% and 10.5% of those oils respectively. [2]
The first U.S. patent for pharmaceutical inks was filed on 28 June 1966, and its method involved ethyl alcohol, shellac, titanium dioxide and propylene glycol.. Most pharmaceutical inks since the early 1990s eliminate ethyl alcohol in favour of faster ink drying times, and may include methyl alcohol and isopropanol in addition to the traditional ingredients titanium dioxide and propylene glycol.
Elemi (Canarium luzonicum) essential oil in clear glass vial Elemicin is named after Canarium luzonicum, one of the vernacular names of which is elemi. Elemi resin is a pale yellow substance, of honey-like consistency. Aromatic elemi oil is steam distilled from the resin. It is a fragrant resin with a sharp pine and lemon-like scent.
Surfactants reduce the surface tension of the ink; distilled water has a surface tension of 72 dyn/cm (72 × 10 −3 N/m), but the desirable value for ink is between 38 and 45 dyn/cm (38 to 45 × 10 −3 N/m). If the ink's surface tension were too high, then it would not flow through the pen; if it were too low, then the ink would run out of ...
Ink drawing of Ganesha under an umbrella (early 19th century). Ink, called masi, an admixture of several chemical components, has been used in India since at least the 4th century BC.

A permanent marker can also be removed by drawing over it with a dry erase marker on non-porous surfaces such as a whiteboard, [3] as dry erase markers also contain a non-polar solvent. Most dry-erase board cleaner solutions also contain effective organic solvents like 2-butoxyethanol to remove the pigment.
[3] In the process of checking the quality, specialists will check in the lab for physical and chemical characteristics such as pH determination, viscosity checks, appearance and odor evaluations. In case of mistake such as the ingredients are not enough for making correction fluid, this problem will be solved by adding more ingredients.
