Understanding Titanium Dioxide CAS Number and Its Significance

Titanium dioxide, chemically represented as TiO2, is a white, opaque powder that is widely recognized for its versatility and applicability in various industries. Its unique properties, such as high refractive index, brightness, and ability to absorb ultraviolet light, make it an essential ingredient in multiple products ranging from paints and coatings to food and cosmetics. The unique identifier for titanium dioxide in scientific contexts is its CAS (Chemical Abstracts Service) number, which is 13463-67-7.

The CAS number serves as a unique numerical identifier for chemical substances, providing a standardized way to identify and classify them. For titanium dioxide, this number helps researchers, manufacturers, and regulatory bodies communicate clearly about this compound. Given the vast array of chemicals in existence, the CAS system, established in 1965, streamlines the process of chemical identification and tracking, critical for compliance with safety regulations.

One of the most common uses of titanium dioxide is in the paint and coatings industry, where it acts as a pigment due to its excellent opacity and brightness. Its ability to scatter light makes it a preferred choice for white paints, providing coverage and color stability. Additionally, titanium dioxide is used in the production of plastics, paper, and inks, enhancing the durability and aesthetic appeal of these materials.

In the field of cosmetics, titanium dioxide serves both as a pigment and a sunscreen agent. Its ability to reflect and scatter UV rays makes it a popular choice in sunblock formulations. The compound is deemed safe for use in cosmetics and is included in the lists of approved substances by regulatory bodies worldwide, such as the Food and Drug Administration (FDA) and the European Commission.

Moreover, titanium dioxide is also utilized in food products as a coloring agent, designated as E171 in Europe and recognized as safe when used within approved limits. However, the use of titanium dioxide in food has come under scrutiny, leading to discussions about potential health risks. Regulatory agencies continue to evaluate the safety of titanium dioxide consumption, underscoring the importance of adhering to established safety guidelines.

In recent years, there has been a growing interest in the potential of titanium dioxide in environmental applications. Researchers are exploring its use in photocatalysis, a process where titanium dioxide can break down pollutants in air and water when activated by light. This property holds great promise for the development of eco-friendly technologies aimed at reducing environmental pollution.

In summary, titanium dioxide, with its CAS number 13463-67-7, is a critical chemical compound with diverse applications spanning various industries. Its significance is underscored by its unique properties and the ongoing research into its applications, particularly in sustainability. As regulatory scrutiny continues and scientific understanding evolves, the role of titanium dioxide in our lives will likely expand, highlighting the importance of this versatile compound in modern society.
