What is titanium dioxide? Why is it used in food products?

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!!

Titanium dioxide (TiO₂) is by far the most suited white pigment to obtain whiteness and hiding power in coatings, inks and plastics. This is because it has an extremely high refractive index and it does not absorb visible light. TiO₂ is also readily available as particles with the right size (d ≈ 280 nm) and the right shape (more or less spherical) as well as with a variety of post-treatments.

However, the pigment is expensive, especially when the volume prices of systems are used. And, there always remains a need to develop a full-proof strategy to obtain the best results in terms of cost/performance ratio, scattering efficiency, dispersion… while using it in coating formulations. Are you searching for the same?

Explore the detailed knowledge of TiO₂ pigment, its scattering efficiency, optimization, selection, etc. to achieve the best possible white color strength and hiding power in your formulations.

In food, titanium dioxide is often used as an artificial color additive. Tasha Stoiber, senior scientist at the consumer health nonprofit Environmental Working Group, says titanium dioxide can generally be thought of as a paint primer – it often goes on a hard-shelled candy like Skittles before the color is added to give it a uniform shine.

Titanium dioxide (TiO2) is a versatile and widely used inorganic compound that has numerous applications, ranging from pigments in paints and coatings to cosmetics and pharmaceuticals. As a result, the demand for TiO2 powder suppliers has been steadily increasing.
