It’s sort of funny-one of my childhood recollections is a discussion with my mother (the PhD in organic chemistry) regarding the virtues of Phisohex (hexaclorrphene, Septisol), a facial cleaner. “Phisohex is pH balanced,” she said, “so it is better for your skin.” At the time, the pH comment wasn’t important to me. What was important was that my mother said I should use it, and therefore the characteristic 1970s green bottle of Phisohex was standard at each sink in our home.
