Question
Posted on: March 6 2013We have a problem with the preparation of the mouthwash: Phenosalyl 1.6 g Borax 37.5 g after bicarbonate 37.5 g after salicylate 10g mint 3g simple syrup 62.5 g Aqua
Dist. AD 500g < br/> After the preparation we obtained a nice solution, but after a night there were crystals, presumably crystals borax. After the necessary search work it was found that borax is present above z & #039; n Solubility. A possible solution could therefore be a reduction in the borax, but we fear loss of activity. Another solution might be the addition of glycerol as borax would dissolve in it, but here the taste plays a limiting factor.
Answer
Usually these compounds contain a certain amount of glycerin. When adding glycerin to Borax, Boroglycerine is associated with the formation of an acidic pH, which is then neutralised by the bicarbonate. The formed acidity depends on the amount of borax and the amount of glycerin. So the solution can bubbling. In your case I would add 50g glycerin. You should also pay attention to the order of addition of the ingredients in order to preserve the bicarbonate as much as possible. Some pH strips at hand are very useful here!
the question, which also poses here is: "What is the phenosalyl?" I believe that in the pharmacy there are also mouthwash agents (specialties) based on phenol. Maybe put everything next to each other and analyse it?
