Titanium dioxide

Dear all, 
I want to substitute titanium dioxide in a hard soap
Is the zinc oxide the right choice or there is another substituent that may do the trick
Best regards 


  • Tyss If you want to replace titanium dioxide as whitening agent, you could maybe try some starch (like Tapioca) or modified starch (Akzo Nobel has many modified starches), which will also aid in firmness.
