Hyrdoxyapatite Concentration in Biorepair Toothpastes

Biorepair toothpastes use microRepair®, a patented compound composed of biomimetic hydroxyapatite particles, specifically Zinc-Substituted Carbonate Hydroxyapatite. These particles closely mimic the composition of natural tooth enamel, enabling them to integrate with enamel and dentin, thereby aiding in remineralization and repair.
The concentration of microRepair® varies across different Biorepair formulations. For instance, Biorepair Plus Sensitive Teeth Toothpaste contains a high concentration of microRepair®, at 240 mg/g (24%), while Biorepair Plus Total Protection Toothpaste contains 200 mg/g (20%) of microRepair®.
Given that microRepair® is primarily composed of hydroxyapatite, these concentrations suggest that these formulations provide a substantial amount of hydroxyapatite, potentially aligning with your interest in a toothpaste containing approximately 10% pure hydroxyapatite.

It's important to note that microRepair® also includes zinc ions, which contribute to its antibacterial properties. The percentage of zinc included is compliant with the limits established by the Cosmetic Regulation. However, the exact proportion of zinc within microRepair® isn't specified in the available information.
Additionally, it's worth mentioning that mass-market Biorepair toothpaste formulations typically contain a minimum of 15% microRepair® (hydroxyapatite).
