Widely used in textile industry to enhance the visual appearance of fabrics by absorbing ultraviolet light and emitting blue fluorescence, making materials look brighter and whiter. Commonly applied in cotton, polyester, and their blends during dyeing or finishing processes. Also found in paper manufacturing to improve whiteness and brightness of high-quality printing papers and packaging materials. Used in some laundry detergents to counteract yellowing of clothes after repeated washes. Effective under daylight conditions where UV light is present, contributing to a cleaner, fresher look of treated surfaces.
