C.I. Fluorescent Brightener 230 is a high-performance fluorescent whitening agent mainly used for optical brightening of synthetic fibers, plastics, coatings, detergents, paper, and polymer materials. It absorbs ultraviolet light and converts it into blue fluorescence, improving the whiteness, brightness, and visual appearance of treated materials. It is widely applied in textile finishing, plastic modification, detergent formulations, and specialty polymer applications.
