Sodium fluoride (NaF) is the most common source of fluoride, but stannous fluoride (SnF 2), olaflur (an organic salt of fluoride), and sodium monofluorophosphate (Na 2 PO 3 F) are also used.
Fluoride in various forms is the most popular active ingredient in toothpaste to prevent cavities. Fluoride occurs in small amounts in plants, animals, and some natural water sources. The additional fluoride in toothpaste has beneficial effects on the formation of dental enamel and bones.Sodium fluoride (NaF) is the most common source of fluoride, but stannous fluoride (SnF 2), olaflur (an organic salt of fluoride), and sodium monofluorophosphate (Na 2 PO 3 F) are also used.ayered toothpaste requires a multi-chamber design (e.g. USPTO 5,020,694), in which two or three layers extrude out of the nozzle.
