Functional Principle and Performance of Fluorescent Whitening Agents

Our optical brighteners, also known as Optical Brightening Agents (OBA), Fluorescent Brighteners (FB), Fluorescent Brightening Agents (FBA), and Fluorescent Whitening Agents (FWA), work through the principle of fluorescence. When exposed to UV light, they absorb energy and re-emit it as visible light, thereby enhancing the brightness and whiteness of coated materials. This fluorescence effect provides treated products with a radiant, vibrant look, making them visually appealing to consumers.

Versatile Applications Across Industries
