CAS 1533-45-5: Fluorescent Brightener 393

Description: Fluorescent Brightener 393, also known by its chemical name as a stilbene derivative, is a synthetic organic compound primarily used as a fluorescent whitening agent in various applications, including textiles, paper, and detergents. Its chemical structure allows it to absorb ultraviolet light and re-emit it as visible blue light, effectively enhancing the brightness and whiteness of materials. This compound is characterized by its high solubility in water and organic solvents, making it versatile for different formulations. Fluorescent Brightener 393 is known for its stability under normal conditions, although it may degrade under extreme pH levels or prolonged exposure to sunlight. It is generally considered safe for use in consumer products, but like many chemical substances, it should be handled with care to avoid potential skin or eye irritation. Its effectiveness and efficiency in improving the appearance of materials have made it a popular choice in various industries, contributing to the aesthetic appeal of finished products.
