Fluorescent Whitening Agents

Fluorescent whitening agents, also known as optical brighteners, are substances added to products like laundry detergents and paper to enhance their brightness. They work by absorbing ultraviolet light and re-emitting it as visible blue light, which makes materials appear whiter and brighter to the human eye. This effect counteracts the natural yellowing of fabrics and surfaces over time. These agents are commonly used in everyday items to improve their appearance, giving a fresh, clean look. While effective, they can sometimes cause sensitivity in certain individuals or environmental concerns if not managed properly.
