In the specialized domain of textile manufacturing, the demand for precise chemical solutions to achieve specific fabric properties is ever-growing. For cotton and its versatile blends, achieving a pristine white often requires a specialty chemical. NINGBO INNO PHARMCHEM CO.,LTD. is proud to offer Optical Brightening Agent 4BK, an advanced compound tailored to deliver unparalleled whiteness and vibrancy to these crucial textile materials.


Optical Brightening Agent 4BK is not just any whitening agent; it's a meticulously developed fluorescent brightener specifically engineered for optimal performance on cotton and polyester-cotton blends. Its unique chemical structure allows it to absorb UV light and re-emit it as visible blue light, effectively masking any inherent yellowness in the fibers. This optical enhancement results in a pure, brilliant white that significantly elevates the aesthetic appeal of the final product.


The 4BK fluorescent brightener properties include exceptional washfastness and high bath exhaustion, ensuring that the desired whiteness is not only achieved efficiently but also sustained through multiple washes. This durability is a critical advantage for manufacturers aiming for high-quality, long-lasting textiles. Moreover, its excellent stability to alkalis, peroxides, and electrolytes makes it a robust choice for integration into various industrial textile processing conditions without degradation of performance.
