NINGBO INNO PHARMCHEM CO.,LTD. offers Sylic® Fluorescent Whitening Agent OBA CXT 71, a state-of-the-art fluorescent whitening agent for cellulosic fibers, and provides technical guidance to help industry professionals master its application for superior results.


Sylic® OBA CXT 71, a stilbene derivative, is specifically formulated to provide a high and brilliant white maximum with a desirable bluish-white shade, effectively correcting the inherent yellowing of cotton, other cellulosic materials, and polyamide blends. Its anionic ionicity and powder appearance make it suitable for precise dosing and integration into various textile auxiliary systems. Understanding its chemical structure and properties is the first step in optimizing its performance in your process.


This optical brightener for cotton bleaching process is highly effective in diverse application methods, including the exhaust process, where its very high bath exhaustion ensures minimal chemical waste and maximum effect. For integrated processes, its compatibility with peroxide bleaching systems for cotton is a significant advantage, allowing for a combined desizing, scouring, and whitening bath. Furthermore, for continuous operations, technical parameters like padding liquor pick-up (70-80%) and temperature (below 160ºC) are critical for achieving uniform whitening in short dwell times (20-30 seconds).

We encourage professionals to study the recommended dosages (e.g., FWA 4BK 0.2-0.6% o.w.f for normal exhaust process) and liquor ratios (1:10-20) to fine-tune their operations.
