Selecting the optimal chemical additive is crucial for achieving desired product performance and market differentiation. In the realm of whitening agents, Optical Brightener CXT (C.I. 71) has established itself as a superior choice, particularly when compared to older alternatives like VBL and 31#. NINGBO INNO PHARMCHEM CO.,LTD., as a dedicated manufacturer and supplier, offers insights into why CXT is the preferred fluorescent whitening agent for many industries.

Optical Brightener CXT belongs to a class of compounds designed to enhance perceived whiteness by converting UV light into visible blue light, thereby masking yellowing. Its advanced molecular structure, featuring morpholine groups, confers several key advantages over earlier formulations. Primarily, CXT exhibits significantly improved resistance to acids and perborates, which are common components in detergent formulations and textile processing. This enhanced stability ensures that the whitening effect remains potent and consistent throughout various application conditions.

A critical comparison point for detergent and textile manufacturers is resistance to chlorine bleaching. Optical Brightener CXT demonstrates superior performance in this regard when benchmarked against VBL and 31#. This greater resilience means that products treated with CXT can better withstand standard bleaching cycles without losing their enhanced brightness, leading to greater product longevity and consumer satisfaction. The agent’s anionic ionization and cyan fluorescence are also optimized for broad applicability across different fibers and washing conditions, making it a versatile choice.

For manufacturers seeking to buy Optical Brightener CXT, understanding these performance differences is vital. The high compounding quantity and cumulative washing whiteness offered by CXT translate into more effective and longer-lasting results for consumers, whether in laundry detergents or brightened textiles. This makes CXT a more cost-effective solution in the long run, despite potential initial price differences compared to older agents. As a leading manufacturer in China, NINGBO INNO PHARMCHEM CO.,LTD. provides competitive pricing and consistent quality for CXT, ensuring you have access to this advanced solution.

The optimal pH range for CXT in dye baths is typically between 7 and 10, with a light fastness rating of grade 4, making it suitable for a wide array of textile applications. In detergent formulations, dosages usually range from 0.1-0.5%, while in printing and dyeing, 0.1%-0.3% is common.
