Understanding the CAS Number of Titanium Dioxide

Titanium dioxide, a compound with the chemical formula TiO2, has gained prominence across various industries due to its exceptional properties. One of the primary identifiers for titanium dioxide in scientific and regulatory contexts is its Chemical Abstracts Service (CAS) registry number, which is 13463-67-7. Understanding this identifier and the compound it represents is essential for comprehending the applications and implications of titanium dioxide.

Titanium dioxide is celebrated for its outstanding opacity and brightness, which can brighten colors and provide a protective barrier. This makes it a popular choice as a pigment in paints, coatings, plastics, and paper products. The compound is also used in food products as a coloring agent, designated as E171 in the European Union. The safety and regulatory status of titanium dioxide have garnered significant attention in recent years, especially concerning its potential health effects when inhaled in nanoparticle form.

Beyond its use as a pigment, titanium dioxide possesses excellent photocatalytic properties, making it useful in environmental applications. The ability of TiO2 to drive chemical reactions under UV light enables its use in air and water purification systems. Titanium dioxide can break down organic pollutants, leading to cleaner environments and reduced energy costs in various industrial processes.

Despite its various applications and benefits, regulatory scrutiny around titanium dioxide has intensified, particularly in the EU, where it has been classified as a possible carcinogen when inhaled in powdered forms. This classification has implications for how it is used in consumer products and has triggered debate over its safety in various applications. In many regions, the acceptable concentration levels and safety measures during production and usage are under continuous review to mitigate any potential risks.

Moreover, titanium dioxide is a vital component in the cosmetics industry, where it is employed in sunscreens and makeup products. Its UV-blocking capabilities protect the skin from harmful sun rays, making it a preferred ingredient in many formulations. The global push for transparency and consumer awareness regarding ingredient safety has prompted manufacturers to revisit their formulations and provide clearer labeling regarding the presence of titanium dioxide in their products.

In summary, the CAS number 13463-67-7 serves as a concise reference for titanium dioxide, highlighting its significance across numerous applications. As industries continue to innovate and evolve, understanding the properties, applications, and regulatory status of titanium dioxide will remain critical. While it is a compound with exceptional versatility and benefits, ongoing research and dialogue surrounding its safety will be crucial in shaping its future in various domains, from manufacturing to consumer products. As we advance, ensuring the safe use of titanium dioxide will not only foster innovation but also protect public health and the environment.
