Selecting the appropriate chemical additive is critical for achieving desired product performance and aesthetics. Optical Brightener CXT, a prominent fluorescent whitening agent, offers a unique set of properties that make it a preferred choice in many industries, particularly in detergents and textiles. Understanding these characteristics is key to leveraging its full potential.

The fundamental identity of Optical Brightener CXT is defined by its chemical composition and CAS number: 16090-02-1. As a stilbene derivative, its molecular structure (C40H38N12Na2O8S2) is designed for efficient light absorption and emission. Its appearance is typically described as a pale yellow to white powder, indicating its solid form and a slight inherent coloration that is transformed into brilliant white through fluorescence.

One of the most lauded properties of Optical Brightener CXT is its excellent brightening efficiency. This means that even at relatively low concentrations, it can significantly enhance the whiteness and brightness of materials. This efficiency is crucial for cost-effectiveness in manufacturing processes. Furthermore, its performance in detergents is particularly noteworthy, characterized by high compatibility and a high accumulative washing whiteness. This means that repeated use of detergents containing CXT leads to progressively brighter fabrics, a significant consumer benefit.

In terms of chemical resistance, Optical Brightener CXT demonstrates improved properties compared to some other optical brighteners. It exhibits good resistance to acids and perborates, which are common components in cleaning products and textile treatments. While it has better resistance to chlorine bleaching than certain older alternatives (like VBL and 31#), careful application and concentration management are advised to ensure optimal results and prevent degradation. Its optimal pH range for dyeing baths is typically between 7 and 10, and it generally offers a light fastness of grade 4, which is considered good for many applications.

Beyond its primary applications in detergents and textiles, Optical Brightener CXT also finds utility in the plastics and paper industries. Its ability to provide a clean, bright appearance makes it a valuable additive for enhancing the visual appeal of these materials. The consistency of its performance across different applications makes it a versatile choice for chemical formulators.

For businesses looking to procure Optical Brightener CXT, sourcing from reputable manufacturers and suppliers is essential. Reliable suppliers, often found in China, provide detailed product specifications, technical data sheets, and quality certifications. These resources are invaluable for ensuring that the purchased brightener meets the required purity, strength, and resistance standards for the intended application. Investigating suppliers that can offer competitive pricing alongside consistent quality is a key step in the procurement process.

In conclusion, Optical Brightener CXT is a high-performance fluorescent whitening agent valued for its excellent brightening efficiency, beneficial chemical resistance, and strong compatibility in detergents. Its ability to deliver accumulative whitening effects and its versatility across multiple industries make it a cornerstone chemical for achieving superior product aesthetics.
