Understanding CAS No. 13463-67-7 An Overview of Titanium Dioxide

Titanium dioxide, identified by the Chemical Abstracts Service (CAS) number 13463-67-7, is a widely used white pigment and is a core ingredient in various industries due to its remarkable properties. It is particularly known for its outstanding opacity, brightness, and durability. This compound is commonly found in products ranging from paints and coatings to plastics, cosmetics, and food.

Titanium dioxide is produced through two primary processes the sulfate process and the chloride process. The sulfate process involves the reaction of titanium ore with sulfuric acid, resulting in a series of chemical reactions that yield titanium dioxide. Meanwhile, the chloride process utilizes titanium ores that are treated with chlorine to produce titanium tetrachloride, which is then oxidized to form titanium dioxide. The purity and particle size of titanium dioxide can vary depending on the method used, which also affects its performance in various applications.

Applications in Industries

The primary application of titanium dioxide lies in the paint and coatings industry, where it serves as a key pigment that provides opacity and color stability. Its high refractive index and excellent weather resistance make it ideal for outdoor applications. Beyond paints, this compound is extensively utilized in plastics to enhance their whiteness and UV resistance.

In the cosmetic industry, titanium dioxide serves both functional and aesthetic purposes. It is used in sunscreen formulations due to its ability to reflect UV radiation, thus offering protection to the skin. Furthermore, in the realm of food, it is utilized as a food additive (E171) to provide a white color and is commonly found in products such as sauces, confectionery, and dairy items.

Safety and Environmental Concerns

While titanium dioxide has numerous beneficial uses, there have been ongoing discussions regarding its safety, particularly in nanoparticle form. Regulatory bodies have scrutinized its inhalation exposure risks, especially for workers in manufacturing environments. As a result, compliance with safety regulations and thorough occupational health assessments are essential to mitigate potential risks.

In terms of environmental impact, titanium dioxide is relatively inert; however, sustainability practices in its production and usage are becoming significant considerations for many companies. As industries move towards eco-friendly practices, the demand for responsibly sourced and produced titanium dioxide is likely to rise.

Conclusion

CAS No. 13463-67-7, or titanium dioxide, is a versatile chemical compound that plays an integral role in various industries due to its unique properties. Its applications in paints, cosmetics, and food demonstrate its importance, while ongoing research into its safety and environmental impact reflects the evolving landscape of chemical manufacturing. As industries continue to innovate, the uses and regulations surrounding titanium dioxide will undoubtedly progress, highlighting the need for responsible stewardship of this essential compound.
