Titanium Dioxide (CAS Number 13463-67-7) Properties, Uses, and Safety

Titanium dioxide, with the Chemical Abstracts Service (CAS) number 13463-67-7, is a widely used inorganic compound renowned for its outstanding properties and versatility. It is a white, opaque powder that is non-toxic and stable, making it highly suitable for various applications across different industries.

Titanium dioxide is not only limited to industrial uses; it also plays a significant role in the consumer market. In the cosmetics industry, it is commonly found in products such as sunscreens, foundations, and powders. Its UV-filtering properties help protect the skin from harmful sun rays, making it a key ingredient for sun protection formulations. Furthermore, its opacity allows for the formulation of makeup products with a smooth finish, providing an appealing appearance on the skin.

In addition to its use as a pigment, titanium dioxide has gained attention for its photocatalytic properties. When exposed to UV light, it can catalyze chemical reactions, making it valuable in environmental applications. For instance, titanium dioxide is used in self-cleaning surfaces and air purification systems. Its ability to break down organic contaminants and pollutants under UV light helps in reducing urban smog and improving air quality. This aspect makes titanium dioxide a fascinating subject of research and development for sustainable technologies.

While titanium dioxide is generally recognized as safe, it is essential to understand the potential health risks associated with its inhalation. In recent years, concerns have been raised regarding its classification as a potential carcinogen when in nano-sized form, particularly in inhalable powders used in industrial settings. Therefore, appropriate safety measures, such as using personal protective equipment and ensuring proper ventilation during handling, are crucial to minimize exposure.

Moreover, regulatory bodies like the European Chemicals Agency (ECHA) and the U.S. Environmental Protection Agency (EPA) have established guidelines and regulations governing the use of titanium dioxide in consumer products. As a response to public health concerns, the European Union has banned its use in certain applications, ensuring that safety remains a priority.

In conclusion, titanium dioxide (CAS Number 13463-67-7) is a remarkable compound with a vast array of applications ranging from industrial uses as a pigment to innovative environmental technologies. Its unique properties contribute to its popularity in numerous sectors, including paints, cosmetics, and environmental applications. However, awareness of its safe handling and regulatory guidelines is imperative to ensure that its benefits can be harnessed without compromising human health. As research continues to explore new applications and safety measures, titanium dioxide remains a crucial component in modern science and industry, favorably impacting our daily lives.
