Understanding Titanium Dioxide CAS Number and Its Significance

Titanium Dioxide, often referred to as TiO2, is a widely used inorganic compound noted for its brightness and versatility. Its primary CAS (Chemical Abstracts Service) number is 13463-67-7. This number is crucial for identifying the substance in various scientific, regulatory, and industrial contexts, making it easier to search for data pertaining to this compound.

TiO2 is characterized by its white color, non-toxic nature, and excellent UV light absorption. It is primarily utilized as a pigment in products ranging from paints, coatings, inks, and plastics to cosmetics and food items. Its ability to effectively scatter light makes it an ideal choice for enhancing brightness and opacity in various applications.

In the paint industry, TiO2 serves as a primary pigment due to its high refractive index and strong hiding power. This means that even small amounts can achieve substantial opacity and whiteness, thus requiring less material while maintaining quality. In plastics, it not only imparts color but also helps in UV stabilization, prolonging the life of plastic products by protecting them from sun damage.

Titanium Dioxide is also gaining popularity in the cosmetic industry, where it is used in products such as sunscreens, foundations, and powders. Its natural UV-blocking properties make it valuable for protecting the skin from harmful UV rays. The food industry utilizes TiO2 as a food additive to enhance brightness and improve the visual appeal of products, often labeled as E171.

Environmental and Health Considerations

Despite its widespread use, Titanium Dioxide has been the subject of scrutiny regarding its environmental and health impacts. Some studies have raised concerns about the inhalation of fine TiO2 particles, particularly in industrial settings, suggesting potential respiratory health risks. However, when used in products like cosmetics and food, it is generally regarded as safe, especially in its aggregated or coated forms, which minimize any potential toxicity.

Regulatory agencies, including the FDA and the European Food Safety Authority (EFSA), have reviewed the safety of Titanium Dioxide and established guidelines to ensure its safe use in consumer products. The recent trend has seen increased scrutiny and some movements toward banning or restricting its use in specific applications, particularly in food and cosmetics, which has fueled ongoing research into safer alternatives and methods of application.

Conclusion

The CAS number 13463-67-7 represents Titanium Dioxide, a compound crucial to numerous industries due to its unique properties. From enhancing product aesthetics to providing essential protective qualities, TiO2's multifaceted roles cannot be overstated. As regulatory bodies continue to review its safety and environmental impact, the industry remains vigilant in seeking sustainable practices and alternatives.

Knowing the CAS number for Titanium Dioxide facilitates a deeper understanding of its applications and implications in health and the environment. As consumers become more informed and conscious of the ingredients in the products they use, manufacturers are encouraged to ensure transparency and safety in their formulations. The future of Titanium Dioxide will likely revolve around innovation and sustainability, proving that even the most common substances need to evolve in response to changing societal standards and scientific advancements.
