Optical Brighteners are fluorescent whitening agents that absorb UV light and emit visible blue light, making surfaces appear brighter and whiter. Commonly used in personal care and home care products, they enhance the appearance of fabrics, papers, and detergents. Optical Brighteners improve visual whiteness in laundry detergents, soaps, shampoos, and cosmetic formulations by masking yellowing and boosting brightness without altering the material’s inherent color.
