Olaflur is a fluorine salt of the organic type (amine fluoride) used since the end of the 1960s in toothpastes and oral hygiene products. With a PH that is more acidic than inorganic fluoride, it is more effective in the re-mineralization of tooth enamel. However, its manufacturing cost being much higher and its non-compatibility with abrasives derived from calcium, make it found in barely 5% of cosmetic oral hygiene products. It is forbidden in organic.
Surprisingly, the ingredient is not subject to any European regulation. However, it is a fluoride whose rate must not exceed (1500 ppm F) or 0.15% of the total ingredients.
