Fluorescent Brightener BA-L is a fluorescent whitening agent commonly used in the textile, detergent, and paper industries to improve the brightness and whiteness of materials. It works by absorbing ultraviolet light and re-emitting it as blue light, which counteracts yellowish hues, resulting in a whiter and brighter appearance. It is water-soluble and typically added to detergents, laundry products, and paper finishes to enhance the whiteness and brightness of fabrics and paper.
