Re: Tooth Soap

I have been using Ivory pure bar soap. Is this not good?

"Proctor and Gamble advertises Ivory Soap to be 99-44/100% pure. It contains vegetable oils, animal fats, fragrance and, of course, the whipped air that provides its famous buoyancy ("The soap that floats!")."

"Actually it consists of 'foreign and unnecessary substances,'...It all started in 1881 when Harley Procter, son of Procter & Gamble co-founder William Procter and a legendary soap salesman in his own right, decided he needed a new angle to hawk Ivory soap. Then as now people were impressed by scientific testimonials, and Harley decided if he could come up with a lab test showing Ivory was "purer" than other soaps, he'd win sales...The impurities consisted of uncombined alkali, 0.11%; carbonates, 0.28%; and mineral matter, 0.17%. Total: 0.56%. Thinking that "99 and 44/100% pure" had just the right touch of technical authenticity to appeal to the great unwashed, so to speak, Harley began sticking the phrase in Ivory advertisements, and another classic marketing slogan was born. Trouble was, there wasn't a standard for purity in soap, so Harley hired an independent scientific consultant in New York to concoct one. The consultant concluded that a 100% pure soap would consist of nothing but fatty acids and alkali, the somewhat yukky sounding substances that nonetheless are the chief ingredients of most soap."

According to Wikipedia

http://en.wikipedia.org/wiki/Ivory_(soap)


"Ivory soap is more caustic than some milder bars, such as Dove, a non-soap syndet bar. Some consumer investigations have found that Ivory's antimicrobial activity is better than other skin soaps, even those containing antibacterials such as triclosan. A postulate for this effectiveness is the ability of the soap to lyse bacteria efficiently, and to rinse cleanly. The drawback to the soap is its drying effect on the skin, as it easily dissolves natural oils."

You notice, though, that Dove is a non-soap syndet or Synthetic Detergent.
