Fluorescent Brightener 264

Description:

Fluorescent Brightener 264, also known by its CAS number 68971-49-3, is a synthetic organic compound primarily used as a fluorescent whitening agent in various applications, including textiles, paper, and detergents. This compound belongs to the class of stilbene derivatives and is characterized by its ability to absorb ultraviolet light and re-emit it as visible blue light, enhancing the brightness and whiteness of materials. It is typically non-toxic and stable under normal conditions, making it suitable for consumer products. The brightener is soluble in water and organic solvents, which facilitates its incorporation into different formulations. Additionally, it exhibits good thermal stability, allowing it to maintain its fluorescent properties during processing and use. Fluorescent Brightener 264 is often favored for its effectiveness in improving the appearance of fabrics and papers, contributing to a cleaner and more vibrant look. However, its environmental impact and biodegradability are considerations in its use, prompting ongoing research into safer alternatives.
