From the blog post, Triclosan is a chlorinated aromatic hydrocarbon. Translation = it's like a soap, with a molecule of oil - hydrocarbon at one end and chlorine instead of water at the other end. The aromatic means the molecule has a benzene ring and puts out a (usually pleasant) odor. Aromatics also evaporate quickly, (taking dead germs with them apparently.)
Man was made for joy and woe
Then when this we rightly know
Through the world we safely go.
Joy and woe are woven fine
A clothing for the soul divine.
