Exploring CAS 13463-67-7 A Comprehensive Overview

The compound identified by CAS number 13463-67-7 is commonly known as titanium dioxide (TiO2). This substance has garnered significant attention across various industries due to its unique properties and versatile applications. Titanium dioxide is a white, opaque powder that is primarily used as a pigment, but its utility extends far beyond that. In this article, we will delve into the characteristics, applications, and safety considerations associated with titanium dioxide.

Properties of Titanium Dioxide

Titanium dioxide is a naturally occurring mineral that is highly valued for its excellent whitening properties and ability to scatter light. It possesses a high refractive index and is known for its brightness and opacity, making it an ideal choice for use in paints, coatings, and plastics. There are three primary crystalline forms of titanium dioxide rutile, anatase, and brookite, with rutile being the most stable and widely used form.

Additionally, titanium dioxide is known for its non-toxic nature and resistance to degradation, which means it can withstand exposure to UV light and harsh environmental conditions. This durability contributes to its popularity in construction and outdoor applications.

Applications of Titanium Dioxide

2. Food Industry Titanium dioxide is also used as a food additive (E171) to improve the appearance of food products, such as confectionery and bakery items. Its use is subject to regulatory scrutiny, and its safety is continually evaluated by food safety authorities.

3. Cosmetics In cosmetics and personal care products, titanium dioxide serves as a key ingredient in sunscreens, where it acts as a UV filter. Its ability to reflect and scatter UV radiation is crucial for protecting the skin from harmful sun exposure.

4. Photocatalysis Titanium dioxide exhibits photocatalytic properties, making it a valuable component in environmental applications. It can break down pollutants and is used in self-cleaning surfaces, air purification systems, and wastewater treatment processes.

5. Solar Energy In the renewable energy sector, titanium dioxide is employed in dye-sensitized solar cells (DSSCs). Its ability to facilitate electron transport makes it a key material for improving the efficiency of solar energy conversion.

Safety and Environmental Concerns

While titanium dioxide is generally recognized as safe for many applications, there have been concerns regarding its inhalation as a fine particulate in industrial settings. Recent studies suggest a potential link between inhaled titanium dioxide nanoparticles and respiratory issues, prompting regulatory agencies to examine exposure limits closely.

In the food industry, the use of titanium dioxide as a food additive has also faced scrutiny, with some countries re-evaluating its safety due to possible health risks. As a result, manufacturers are encouraged to prioritize consumer safety, transparency, and compliance with regulations.

Conclusion

CAS 13463-67-7, or titanium dioxide, is a remarkable compound with diverse applications across numerous industries. Its properties as a pigment, UV filter, and photocatalyst highlight its versatility. Nevertheless, ongoing research and regulatory assessments are essential to ensure its safe use, particularly concerning inhalation exposure and its application in food products. As industries evolve and sustainability becomes increasingly important, titanium dioxide will likely continue to play a vital role in innovation and product development while balancing safety and environmental concerns.
