TDS of optical brightener CBS-X
CBS-X exhibits strong absorption in the near-UV region and emits blue fluorescence that effectively neutralizes yellow tones in textiles and substrates.
Working Principle of Optical Brightener CBS-X
CBS-X functions by absorbing ultraviolet light and re-emitting it as visible blue fluorescence. This emitted blue light compensates for the inherent yellowish hue of fibers and materials, resulting in a noticeably brighter and cleaner appearance.
Due to its
excellent solubility in water
, Tinopal CBS-X disperses uniformly in aqueous systems, ensuring consistent whitening performance even at low dosages.
Performance Advantages of Optical Brightener CBS-X
CBS-X is recognized as one of the most effective optical brighteners for detergent applications due to the following advantages:
Exceptional Whitening Efficiency
Provides up to
2.7 times higher brightening intensity
on cotton compared with diphenylethylene tristriazine derivatives.
Excellent Fiber Affinity
Highly effective on
cellulosic fibers, polyamide (nylon), and protein fibers
at room temperature.
Outstanding Bleach Resistance
Maintains stable performance in the presence of
sodium hypochlorite
, making it a true bleach-resistant optical brightener.
Superior Solubility and Dispersibility
Rapidly dissolves in water, ensuring uniform optical effects without sedimentation.
Versatility in Aqueous Formulations
Suitable not only for detergents and soaps but also for
water-based paints and inks
.
