Chemistry & Chemical Engineering


Chemistry/Chemical Engineering

The big difference between chemistry and chemical engineering has to do with originality and scale. Chemists are more likely to develop novel materials and processes, while chemical engineers are more likely to take these materials and processes and upscale them to make them larger or more efficient.  Therefore, we strive to teach applied chemistry and engineering such as pharmaceutical sciences.

For chemical and pharmaceutical engineering project, this is an example that a feasibility of intraorally delivering vitamin B6 by adding into the formulation of toothpaste was investigated because it was deemed to be an amazing match, considering the importance of regular administration of vitamin B6 without forgetting as usually done most patients.

An emulsion-based toothpaste was formulated with a probiotic and vitamin B6, reinforced with chemical penetration enhancer azone and other typical ingredients. Various characteristics of our probiotic vitamin B6 toothpaste was compared with those of other commercial brand toothpaste.  The characteristics include abrasiveness, scratchiness, spreadability, pH, foaming, cleaning, and antibacterial ability. And, a transepithelial electrical resistance (TEER) value was measured with Lumbricus Terrestris skin.  The study concluded that our probiotic vitamin B6 toothpaste had comparable characteristics with other commercial toothpaste. TEER value demonstrated that our formulation had high feasibility of vitamin B6 delivery.

Emulsion industry is very important since it is the main technology for cosmetics, paints, inks and most nanoparticles.  Many other fields are among our science fields to be developed.
