What is the difference between BioMin® F & BioMin® C?

BioMin® F and BioMin® C additives are from the same family of bioactive glass materials, designed to put back the lost apatite mineral that is dissolved from tooth surfaces on a daily basis, but what are the differences between BioMin® F and BioMin® C...

BioMin® F

BioMin® F contains Fluoride in the glass besides Calcium and Phosphate. As the glass starts to dissolve in saliva these three ions combine to precipitate Fluorapatite on the tooth surface. Fluorapatite is more resistant to acid attack than hydroxyapatite by a factor of 10.

BioMin® F foaming Fluoride toothpaste incorporates fine BioMin® F particles to supply a low levels of Fluoride for up to 12 hours after brushing. The Fluoride content of the toothpaste is below 600ppm and is slowly released in a controlled manner as saliva dissolves the fine glass particles. The Fluoride will combine with Calcium Phosphate also released from the glass to produce acid resistant Fluorapatite.

BioMin® C

Within the BioMin® C glass material, a Chloride ion replaces the Fluoride ion incorporated in BioMin® F glass. BioMin® C is a more reactive glass and develops apatite formation more rapidly, however it does not provide the enhanced acid resistance of BioMin® F since Hydroxyapatite is precipitated onto the tooth surfaces rather than Fluorapatite. 

The development of this additive has lead to the creation of the FLUORIDE FREE toothpaste, BioMin® C.
