Titanium Dioxide, CAS# 13463-67-7, is a naturally occurring oxide of titanium manufactured through chemical synthesis from high titanium mineral and strong acid, available as WHITE POWDER. Titanium Dioxide is widely used as colouring agent as it is the whitest substance ever discovered. It is affirmed by US FDA as GRAS(generally recognized as safe) and widely accepted as safe food additive in many countries with E number E171.
No significant side effects reported.
As Titanium Dioxide is widely known as safe, there is no limit on dosage of intake. However, we still recommend consumers to consult professionals before using large quantity of Titanium Dioxide for long period.
Special groups refer to newborns, children, pregnant and any other applicable vulnerable groups.
There is no evidence that Titanium Dioxide could have any negative effects on these vulnerable groups. It should be safe to use Titanium Dioxide in food for newborns and pregnant. However, we still recommend consumers to consult professionals before using large quantity of Titanium Dioxide for long period in food for newborns or pregnant.
