What is the FDA limit for titanium dioxide?
If you want to avoid titanium dioxide, Stoiber and Faber urge consumers to try and avoid processed foods as best as you can.
Where does titanium dioxide come from?
- In conclusion, the use of titanium dioxide in the plastic and dyeing industries has revolutionized the way we produce and enhance materials. R218 factory has been at the forefront of this innovation, producing top-quality titanium dioxide that helps manufacturers create durable, vibrant, and environmentally friendly products. As the demand for titanium dioxide continues to rise, R218 factory is poised to remain a key player in the industry, providing essential solutions for a wide range of applications.
- Furthermore, TiO2 is also utilized in food and pharmaceutical industries as a colorant and additive, owing to its inertness and non-reactive nature. However, its use in these sectors is strictly regulated to ensure consumer safety.
Though the Food and Drug Administration (FDA) categorizes titanium dioxide as Generally Recognized as Safe (8), other organizations have issued warnings.

Now imagine the delicate skin on your face, on your children’s arms & legs. Each day un-knowingly, thinking we are doing the right thing, we slather them up with titanium dioxide in the form of sunscreen & send them out into the sun, all the while never knowing that once exposed to light titanium dioxide creates free radicals that are strong enough to damage steel roofing panels!!
Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors the pigment itself can vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant may be used, such as a small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.

However, humans are not exposed to E171 in drinking water at any significant quantity over a long duration, so this potential effect is irrelevant to the human experience. It’s important to understand that a potential hazard is not the same thing as an actual risk.
When examining a lithopone pigment pricelist, one might notice that prices can vary significantly between different grades of lithopone. Generally, there are two main types Lithopone 28 and Lithopone 60, with the numbers denoting the percentage of zinc sulfide content. Lithopone 28, with a lower zinc sulfide content, is often more affordable compared to Lithopone 60, which offers superior whiteness and opacity. The choice between these grades depends largely on the specific requirements of the end application.
