Fluorescent Brightener 135

Description:
Fluorescent Brightener 135, also known by its CAS number 12224-12-3, is a synthetic organic compound commonly used as a fluorescent whitening agent in various applications, particularly in the textile and paper industries. This compound belongs to the class of stilbene derivatives and exhibits strong fluorescence under ultraviolet light, enhancing the brightness and whiteness of materials. Its chemical structure typically includes sulfonate groups, which improve its solubility in water and effectiveness in aqueous environments. Fluorescent Brightener 135 is often utilized in laundry detergents, paper products, and plastics to counteract yellowing and improve visual appeal. It is generally considered to be stable under normal conditions, although its performance can be affected by factors such as pH and temperature. Safety assessments indicate that while it is effective in its applications, proper handling and usage guidelines should be followed to minimize any potential environmental impact or health risks associated with exposure.
