Companies come up with new combinations of chemicals and other crap to dump in their products all the time.

But they can't just say
"Certs® adds Vegetable Oil to make our mints shiny!",
so they call it "Retsin®."

To see a fantastic fictional example of the Marketing Department controlling the naming of products, you must rent the film "Brain Candy."

Anyway, whatever they're shoving into this bottle of Ben Gay®, be it more Menthol, or acetylsalicylic acid, or whatever, they had to give it a Scientific name--

TRIGESIC
A Pain Reliever Times Three!

To prove how Scientific this Scientific new product is, they put what appear to be molecule diagrams on a chalkboard behind the product.
