Functional principle and performance of fluorescent whitening agents
7 Jan 2019
Our optical brighteners, also known as optical brightening agents (OBA), fluorescent brighteners (FB), fluorescent brightening agents (FBA), and fluorescent whitening agents (FWA), work through a process based on fluorescence. When exposed to UV light, they absorb the light energy and re-emit it as visible light, enhancing the brightness and whiteness of the coated material. This mechanism gives treated products a shiny, vibrant appearance, making them visually appealing to consumers.
