Understanding Titanium Dioxide CAS Number and Applications

Titanium dioxide (TiO2) is a widely used compound prized for its unique properties, including high refractive index, strong UV light absorption, and excellent thermal stability. It plays a crucial role in various industries, from cosmetics to construction. For anyone looking to understand more about this versatile compound, the Chemical Abstracts Service (CAS) number for titanium dioxide is a useful reference. The CAS number for titanium dioxide is 13463-67-7, which is universally recognized and facilitates streamlined communication within scientific and regulatory contexts.

In the cosmetics industry, titanium dioxide is a common ingredient in sunscreens and makeup products. Its ability to block UV radiation makes it a critical component for sun protection formulations. The compound acts as a physical sunscreen, creating a barrier that reflects and scatters harmful UV rays away from the skin, thereby reducing the risk of sunburn and skin damage. The safety profile of titanium dioxide further enhances its appeal, as it is generally recognized as safe for topical use when applied in appropriate concentrations.

Beyond its roles in pigmentation and cosmetics, titanium dioxide is also utilized in the food industry as a coloring agent. It is particularly noted for its ability to provide whiteness in products like confectioneries, dairy items, and sauces. Despite its widespread use, there are ongoing discussions regarding the safety of nano-sized titanium dioxide particles when ingested, prompting regulatory bodies to review its usage.

Moreover, titanium dioxide's photocatalytic properties are harnessed in environmental applications, particularly in air and water treatment. When exposed to ultraviolet light, TiO2 can break down pollutants, making it valuable for purifying air and promoting cleaner environmental practices.

In conclusion, titanium dioxide, identified by its CAS number 13463-67-7, is a multifaceted compound with applications spanning multiple industries. Its effectiveness as a pigment, UV filter, and photocatalyst underscores its importance in both consumer products and environmental solutions. As research continues and technologies evolve, titanium dioxide remains a pivotal material in the quest for innovation and sustainability.
