What is titanium dioxide commonly used for?

Titanium dioxide (TiO₂) is widely used across various industries due to its chemical stability, brightness, and ability to reflect light. Some of the most common applications include:

1. Paints and Coatings:

TiO₂ is a key pigment in white paints because of its high opacity and brightness, offering excellent coverage.

2. Sunscreen:

Titanium dioxide is used in sunscreens as a physical UV blocker, protecting the skin from harmful ultraviolet radiation.

3. Plastics:

It is added to plastics to improve durability, color, and UV resistance.

4. Cosmetics:

In products like foundation and face powder, it provides coverage and sun protection.

5. Food Additive:

TiO₂ is used as a white food coloring (E171) in items like candy, chewing gum, and sauces.

6. Paper:

It enhances brightness and opacity in paper products.

7. Pharmaceuticals:

Titanium dioxide is used to color and coat tablets and capsules.

These versatile uses stem from TiO₂'s non-reactive, non-toxic nature and its ability to provide whiteness and brightness to products.
