NINGBO INNO PHARMCHEM CO.,LTD. presents Optical Brightener 4BK, a highly effective stilbene derivative that offers a versatile solution for achieving superior whiteness and brightness across multiple industries. Its unique ability to absorb UV light and re-emit it as blue light makes it an invaluable component in applications where enhanced visual appeal is paramount.

In the textile industry, Optical Brightener 4BK is a crucial dyeing auxiliary. It is specifically formulated for cellulosic fibers and polyamide, delivering a brilliant bluish-white finish that masks inherent yellowing. Its excellent wash fastness and stability to alkalis and peroxide ensure that the enhanced whiteness is long-lasting and consistent, even after rigorous processing. This makes it ideal for applications ranging from everyday apparel to high-end home textiles, where vibrant whites are essential. The high bath exhaustion also contributes to its efficiency, allowing for optimal whitening with minimal product usage, a significant benefit for sustainable manufacturing practices.

Beyond textiles, Optical Brightener 4BK finds critical use in industrial detergent formulations. It acts as a detergent whitener, enhancing the perceived cleanliness and brightness of laundered fabrics. When added to detergents, it imparts a brilliant white appearance to whites and revitalizes colors, contributing to the overall effectiveness and consumer appeal of laundry products. The ability of the brightener to deposit onto fabrics during the wash cycle ensures that clothes look brighter and whiter wash after wash.

The paper industry also benefits from the exceptional properties of Optical Brightener 4BK. It is employed in paper brightening processes to significantly enhance the whiteness and visual appeal of various paper products, including printing paper, packaging materials, and specialty papers. By improving the brightness and reducing yellowness, it contributes to a more professional and aesthetically pleasing final product. The good solubility of the brightener in water further aids its incorporation into paper manufacturing processes, ensuring uniform distribution and effective brightening.
