In the washing and daily chemical industry, cleaning products such as washing powder, laundry detergent, and soap must not only have excellent decontamination capabilities, but also improve the whiteness of the fabric to make the clothes present a brighter visual effect after cleaning. Fluorescent brighteners can make fabrics look whiter and brighter by absorbing ultraviolet light and emitting blue light, thereby enhancing the market competitiveness of washing products. We provide efficient and environmentally friendly fluorescent brightener products that are suitable for various washing and daily chemical products.
