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?

  • You could use a white clay or emulsifier/white wax

    @Dr Catherine Pratt A white clay such as kaolin? Or do you have a preferred white clay?
  • Yes I prefer Kaolin clay but there are many to choose from. Hope this helps.

  • Actually you could add 5 to 10% of bicarb as well.

    @Dr Catherine Pratt Thanks for your suggestion. I've just had a 25 kg sack of Kaolin (Halloysite) clay dropped from a rep at Axieo.

    I'll update how I get on - I guess I will need to add more than I used for titanium dioxide.

    Thanks again.
  • No not necessarily, look why don’t you message me privately
