Titanium Dioxide alternatives - what would you suggest?
I have recently started working for a toothpaste manufacturer and one of the first tasks I have been given is to remove titanium dioxide out of toothpaste. The logic is that France has banned titanium dioxide from foods - therefore titanium dioxide will be banned from toothpaste too (I don’t agree with this - but this is marketing directives!). We’ve recently heard from a customer selling toothpaste in Germany wanting to remove titanium dioxide from their products. Also, despite having Sensient supplying us statement to say their material is without nanoparticles - this question comes up often also causing the marketers to want titanium dioxide removed.
The problem is, we manufacture a propolis toothpaste - and propolis over time darkens. Titanium dioxide seems to limit just how much darkening happens.
I’ve been told I can’t use zinc oxide, again, because of the public perception of nanoparticles.
Formula is a basic one - approx. Calcium carbonate 40%, water 25% Glycerol 15%, Sorbitol 70% solution 10%, remainder propolis, flavours, gums, titanium dioxide, SLS, preservatives.Any suggestions as to what I could possibly use instead of titanium dioxide?
