Our Company: Dr. Hu Zhen’s Team Develops New CBS-X Process, Significantly Enhanc
Time：2025-09-27Views：
Recently, after multiple rounds of tests, Dr. Hu Zhen’s team at our company has successfully developed a new production process for the optical brightener CBS-X. This process not only simplifies the workflow but also addresses the insufficient stability of CBS-X (produced via traditional processes) in extreme environments such as high alkalinity (e.g., alkaline scouring/bleaching of denim) and low temperatures (e.g., cold-water washing in winter), providing more reliable raw materials for textile and daily chemical customers at home and abroad.
The team abandoned high-temperature reactions and adopted the "precision low-temperature catalysis + segmented temperature control" technology (reducing catalyst dosage by 12%, with reaction temperature stabilized at -2°C~3°C). Additionally, a "gradient grinding + membrane separation purification" step was added to ensure more uniform particle size (6μm~8μm) and better dispersibility of the finished product. Tests show that CBS-X produced by the new process retains 93% of its whitening strength (up from 76% with the traditional process) after 24 hours in a high-alkaline environment (pH 12~13). When added to laundry detergents at 15°C~20°C (low temperature), it shows no precipitation or caking. Meanwhile, the new process reduces water consumption by 30% and energy consumption by 18%.
"Our R&D is always customer-centric—this breakthrough is to solve customers’ practical concerns," said Dr. Hu Zhen. Currently, the new production line has been commissioned, and new batches of CBS-X have been launched sequentially. This breakthrough strengthens our company’s technological advantages and lays a foundation for expanding into high-end textile and green daily chemical markets. Going forward, we will continue to rely on this team to advance the technological optimization of optical brightener products.
