NINGBO INNO PHARMCHEM CO.,LTD. is proud to offer Optical Brightener CBS-X, a versatile and highly effective fluorescent whitening agent. This article delves into the chemical properties that make CBS-X a superior choice for enhancing whiteness and brightness across various industries.

Optical Brightener CBS-X, chemically known as Disodium 2,2′-([1,1′-biphenyl]-4,4′-diyldivinylene)bis(benzenesulfonate) and identified by CAS number 27344-41-8, belongs to the disulfonic distyrylbiphenyl class of compounds. Its molecular structure is key to its unique performance characteristics. The molecule contains chromophoric groups that allow it to absorb ultraviolet light, typically in the range of 348-350 nm. Upon absorption, it undergoes fluorescence, re-emitting energy as visible blue light. This specific wavelength emission is critical for neutralizing the yellow hues commonly found in many materials.

The physical properties of CBS-X are also noteworthy. It typically appears as a yellow or yellowish-green powder or granule. Its solubility in water is a significant advantage, facilitating easy incorporation into aqueous systems, which are common in detergent and textile applications. The compound exhibits excellent stability under a wide range of conditions. This includes high tolerance to chlorine and oxygen bleaching agents, as well as stability in alkaline environments and across various pH levels. This robustness is a key factor in its widespread use in laundry detergents and textile finishing processes.

The benefits derived from these properties are substantial. For detergents, CBS-X ensures that fabrics appear whiter and brighter even after repeated washing, counteracting fabric yellowing. In textiles, it enhances the inherent whiteness of fibers like cotton, wool, and polyamide, improving the aesthetic appeal of finished garments. For the paper industry, it contributes to higher brightness levels, making printed materials and packaging more visually appealing.

When considering the optical brightener CBS-X benefits, its high affinity to cellulosic fibers is paramount. This ensures efficient uptake and retention by the material, leading to long-lasting whitening effects. The agent also offers good photostability, meaning the whitening effect does not degrade quickly when exposed to light. Additionally, it is recognized for being environmentally friendly, with biodegradability properties that minimize its ecological footprint.
