Question
Posted on: March 6 2013How can we best prepare the toothpaste formula to get a solid consistency? Veegum 5g sorbitol OPL 70% 10g chlorhexidine. Gluco. OPL 20% 0.5 g Ca-carbonate 5g
Na-Laurylsulf 300mg
Lemon oil 2 drupp
Aqua ad 100g < BR/> With us, the result is too liquid.
Answer
but in your composition a major incompatibility is to know this between Ca 2 + and F -. Indeed there will be a minimal amount of Ca ions occurring in the aqueous solution and these can react on the one hand with lauryl sulfate (-) and F (-). There are two solutions to this problem. We may consider adding 1% after 2 EDTA in order to complexate the Ca ions either to consider replacing CACO 3 with silicon dioxide praecipitatum. In the Commerci ë le fluoride containing toothpaste & #039; s, an organic fluoride-containing compound is used, on which the Officina pharmacist can unfortunately not dispose of it.
