There is also some evidence to suggest that exposure to titanium dioxide nanoparticles may be harmful or toxic to the environment, including aquatic life and other organisms. The production and disposal of the mineral may also release pollutants, such as carbon dioxide and sulfur dioxide, into the air and water.

Conclusion

TiO₂ comes in many different forms. However, only a few of these forms are considered food-grade (acceptable to be added to food). Many studies that raised concern about the safety of TiO₂, including the concern for genotoxicity, used forms of TiO₂ that are not considered acceptable for use in food and have different properties than food-grade TiO₂. Other studies did use food-grade TiO₂, but took steps to break the material down into smaller particles than what would normally be found in food.

In terms of application, meticulous preparation and attention to detail yield the best results. For paint grinders, maintaining a ratio of 12 pounds of refined linseed oil to 88 pounds of lithopone pigment will provide optimal workability. A salient factor that should be heeded is the state of the lithopone before mixing with oil; the material must be sufficiently dry. Only then will it integrate seamlessly with the oil, ensuring that the resultant mixture possesses the desired consistency and properties.

Journal Information

Titanium dioxide, a versatile and widely used material, finds its application in various industries including the rubber industry. This white pigment is known for its excellent UV resistance, durability, and opacity, making it an ideal choice for enhancing the properties of rubber products.

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.

There are many ways we’re exposed to titanium dioxide in our everyday life. Below are the most common ways we encounter titanium dioxide.
