Understanding the CAS Number A Deep Dive into CAS 13463-67-7

Chemicals play an integral role in our daily lives, touching everything from agriculture to pharmaceuticals. One critical aspect of chemistry is the need to identify and classify substances accurately. This is where the Chemical Abstracts Service (CAS) numbers come into play. A noteworthy example is CAS number 13463-67-7, which refers to a widely used compound titanium dioxide.

Titanium dioxide (TiO2) is an inorganic compound known for its brilliant white color and high refractive index. This compound is typically found in nature as two minerals rutile and anatase. It is a critical pigment in various applications, thanks to its high opacity and UV resistance. You can find titanium dioxide in everything from paints and coatings to food products and cosmetics.

Applications of Titanium Dioxide

1. Paints and Coatings One of the most common uses of titanium dioxide is in paints and coatings. Due to its exceptional whiteness and UV blocking capacity, it enhances the durability and aesthetic appeal of paints, thereby protecting structures from the harmful effects of sunlight and weathering.

2. Plastics The plastic industry frequently employs titanium dioxide as a whitening agent. It not only improves the appearance of plastics but also contributes to their strength, providing resistance against wear and tear.

3. Cosmetics In cosmetics, titanium dioxide serves dual roles. It acts as a pigment and provides sun protection. Many sunscreens utilize this compound due to its ability to reflect UV light, making it a popular choice for skin protection products.

4. Food Industry Surprisingly, titanium dioxide is also found in food products as an additive, primarily to enhance color and appearance. However, its use in food has raised health concerns, prompting regulations in several countries regarding its safety.

Health and Safety Considerations

While titanium dioxide is generally recognized as safe when used in regulated amounts, concerns have emerged regarding its potential health effects, particularly in its nanoparticle form. Inhalation of titanium dioxide in powder form can lead to respiratory issues, and there are ongoing studies to assess its long-term health impacts fully. Regulatory agencies like the Environmental Protection Agency (EPA) and the European Food Safety Authority (EFSA) continuously evaluate its safety for various applications.

Environmental Impact

The production and disposal of titanium dioxide have environmental implications. The manufacturing process can generate substantial waste, and improper disposal of products containing titanium dioxide can lead to soil and water contamination. There are increasing efforts to develop sustainable methods for sourcing and producing titanium dioxide, employing greener technologies and practices in its lifecycle management.

Conclusion

CAS number 13463-67-7 encapsulates titanium dioxide, a compound that significantly impacts numerous industries due to its unique properties. Whether enhancing the brightness of paint, providing UV protection in sunscreen, or adding color to food, titanium dioxide is ubiquitous in everyday products.

While its benefits are substantial, particularly regarding its functionality and versatility, ongoing research and dialogue surrounding its safety and environmental impact are crucial. Stakeholders, including manufacturers, regulatory bodies, and consumers, must continue to engage with the data and research that surround chemical safety to protect public health and the environment.

In summary, as we delve deeper into the characteristics and implications of CAS 13463-67-7—titanium dioxide—it becomes evident that while this compound offers various advantages across many sectors, a balanced approach considering health, safety, and environmental sustainability is essential for its continued use. Awareness and education about titanium dioxide will further enable informed decisions regarding its application and management, ultimately leading to a more sustainable future.
