You'll wonder where the yellow went
This vintage TV commercial for Pepsodent is something of a classic and almost everyone over a certain age still has the jingle embedded in their brain. The toothpaste is still around apparently.
Wikipedia coyly refers to Pepsodent's miracle ingredient Irium as another word for sodium lauryl sulfate an inexpensive ionic surfactant. It is in fact an inexpensive anionic surfactant - cheap detergent in other words.
