CHAPTER 1: THE PROBLEM AND ITS SETTING
A. INTRODUCTION
Commercial inks used today on our pens and printers as we know are simple but little we know about it is that it has complete compositions. Pen inks that were used in the early times were iron gall inks, but because of its corrosive effect on paper, its component were changed and here they are a little amount of phosphoric acid ester, imidazoline-type activator, polytyethylenealkylamine, polyotyethylent, alkylame and alkylalkanolamide. But these are not the only substances that can be found in pen inks, there may be toluene and xylene, and other heavy metal compounds which may cause skin irritating, nauseas, blurred visions, dizziness and drowsiness. These substances are also non-renewable oils.
Through complicated and extensive research, our team has found a cheaper and safer alternative for the traditional commercial ink. By just replacing the main components which are
