Who invented toothpaste?!
Question:
Who invented toothpaste?
Answers:
The world's oldest-known formula for toothpaste, used more than 1,500 years before Colgate began marketing the first commercial brand in 1873, has been discovered on a piece of dusty papyrus in the basement of a Viennese museum.
In faded black ink made of soot and gum arabic mixed with water, an ancient Egyptian scribe has carefully described what he calls a "powder for white and perfect teeth".
When mixed with saliva in the mouth, it forms a "clean tooth paste".
According to the document, written in the fourth century AD, the ingredients needed for the perfect smile are one drachma of rock salt - a measure equal to one hundredth of an ounce - two drachmas of mint, one drachma of dried iris flower and 20 grains of pepper, all of them crushed and mixed together.
The result is a pungent paste which one Austrian dentist who tried it said made his gums bleed but was a "big improvement" on some toothpaste formulae used as recently as a century ago.
