How Optical Brightening Agents Work

Optical Brightening Agents absorb ultraviolet light and re-emit it as visible blue light. This process gives treated materials a whiter, brighter appearance by reducing yellow undertones. Ideal for textiles, papers, and detergents, the agent integrates seamlessly into production methods like mixing, padding, and spraying, making its application both flexible and highly effective.
