Question
Posted on: April 22 2013Like an alternative to the Afterhypochlorite 3% for dental duct treatment.
Since July 2012, the pharmaceutical grade of sodium hypochlorite is no longer available from Bassron.
I hear that some Officina pharmacists prepare this themselves on the basis of the real Javel (with water), but of course this is only of technical quality. Does anyone of you know an alternative?
Answer
According to NRF, a 1% NaOCl solution contains 9.5 mg of active chlorine per g. For 100 g 3% solution This 2.85 g becomes active chlorine.
Chloramine contains between 25 and 26% active chlorine. So we need 100/25 X 2.85 = 11.4 g chloramine for 100 g solution, equivalent to 3% NaOCl.
This solution should also be stored in a polyethylene bottle and kept in the refrigerator outside the influence of light! Poplypropylene screw caps, which come into direct contact with the Hypoclorite solution, exhibit fragility. PET bottles are not stable and at higher pH precipitation occurs in glass bottles.
