How it works – BioMinF adheres to tooth surfaces and slowly dissolves releasing calcium, phosphate and fluoride ions over a period of 8-12 hours. The surface forms acid resistant fluorapatite (tooth mineral) which makes BioMinF more effective than other toothpastes where the active ingredients are washed away and become ineffective less then two hours after brushing.

Effect of biocides and anionic homopolymeric inhibitors …

Abstract This paper describes the effect of biocides and of the anionic homopolymeric inhibitors on the precipitation behavior of calcium fluoride (CaF 2).The efficiency of inhibitors in the presence and absence of biocides was calculated using the half-life (t 1/2) approach, where 50% of the concentration has been precipitated.. Conductometric and X-ray diffraction (XRD) analysis have been

Mineral Water - an overview | ScienceDirect Topics

The rare mineral waters that are rich in both bicarbonate and calcium inhibit bone resorption even in calcium sufficiency, while calcium-rich waters with low bicarbonate show no effect. Regular consumption of these rare waters with a very high fluoride content resulted in an elevated BMD, but this was mainly a Fluor effect and less a consequence of their alkalinity.
