C.I. Fluorescent Brightener 24

Description:
C.I. Fluorescent Brightener 24, also known by its CAS number 12224-02-1, 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, characterized by its ability to absorb ultraviolet light and re-emit it as visible blue light, thereby enhancing the brightness and whiteness of materials. It is typically a white to pale yellow powder, soluble in organic solvents but less so in water. The brightener functions by converting UV light into visible light, which helps to mask yellowing and improve the overall appearance of products. In addition to its aesthetic applications, C.I. Fluorescent Brightener 24 is also utilized in the plastics and coatings industries. Safety data indicates that while it is generally considered safe for use in consumer products, appropriate handling and safety measures should be observed to minimize exposure.
