How did Procter and Gamble get Ivory soap to float?
Until recently, the legend was that a production plant employee allowed a mixing machine to run too long. But in June 2004, Procter and Gamble company archivist, Ed Rider, discovered that P&G chemist James N. Gamble made floating soap in 1863. Ivory soap was released in 1878 or 79 and they added this feature as a selling point. Procter and Gamble sets the record straight in Rising Tide: Lessons from 165 Years of Brand Building at Procter and Gamble, a book about the 165 year history of the company that was released in summer 2004.
