Understanding TiO2 The Importance of Its CAS Number

Titanium dioxide (TiO2) is a compound widely used in various industries due to its unique properties. It is a white, opaque, and non-toxic powder that serves as a pigment, a catalyst, and a physical sunscreen agent. With a chemical formula of TiO2, this compound is recognized by its unique CAS (Chemical Abstracts Service) number, which is 13463-67-7. This number is crucial not only for identification purposes but also plays a significant role in regulatory compliance, safety assessments, and research.

Properties of TiO2

TiO2 possesses exceptional photocatalytic and UV resistant properties, making it an important material in diverse applications. It is primarily used as a white pigment in paints, coatings, and plastics because of its high refractive index and excellent coverage. This pigment helps to create bright, glossy surfaces that are appealing to consumers.

In addition to its aesthetic applications, TiO2 is utilized in the production of sunscreen products. It acts as a physical barrier that reflects and scatters UV radiation, protecting the skin from harmful rays. Its safety and effectiveness have led to its inclusion in many cosmetic formulations.

In the field of photocatalysis, TiO2 is employed in water and air purification. When exposed to UV light, TiO2 generates reactive oxygen species that can degrade organic pollutants, making it a valuable component in environmental remediation efforts. This property has sparked interest in its use for energy generation through solar cells.

The CAS number for TiO2, 13463-67-7, is a unique numerical identifier assigned by the Chemical Abstracts Service to facilitate the efficient tracking and management of chemical substances. This number eliminates ambiguity in communication among researchers, regulatory agencies, and manufacturers. It ensures that everyone is referring to the same substance, which is especially important in safety data sheets, regulatory filings, and compliance documentation.

Regulators use CAS numbers to monitor the manufacturing and usage of chemicals. In many jurisdictions, products containing TiO2 must adhere to specific guidelines and safety assessments. The CAS number allows regulatory bodies to quickly access information about the compound's safety profile, exposure limits, and environmental impact. As the global demand for TiO2 continues to grow, so does the scrutiny surrounding its production and use.

Current Trends and Future Insights

The TiO2 industry has experienced significant growth due to its broad applications, from construction and automotive industries to healthcare and consumer goods. However, recent concerns regarding the health effects of TiO2, particularly in nanoparticle form, have led to increased scrutiny. Research is ongoing to better understand its toxicity and the implications of long-term exposure.

As a response to these concerns, manufacturers are investing in innovative formulations and production techniques that enhance the safety and sustainability of TiO2. Efforts are being made to develop alternative pigments with lower environmental impact and reduced health risks.

In conclusion, titanium dioxide (TiO2) is an integral compound in various industries, valued for its properties and applications. Its CAS number, 13463-67-7, serves as a vital reference for safety and regulatory matters, underscoring the importance of proper identification and compliance in the chemical industry. As we advance towards more sustainable practices, the future of TiO2 will likely be shaped by ongoing research, regulatory developments, and its evolving role in technology and consumer products.
