It produces a bright neutral white light on pure cotton, polyester-cotton blends, nylon, and wool fabrics.
It does not cause yellowing or greenish discoloration of the fabric even after repeated washing, and the whiteness becomes brighter after every wash. In contrast, DSD Acid-type fluorescent whitening agents can make the fabric turn greener, darker, and reduce the whiteness of the fabric.
Due to its strong solubility at low temperatures, it is suitable for use in liquid detergents. It has excellent stability and whitening effect in ultra-concentrated liquid detergents and heavy-duty liquid detergents.
Since it does not contain nitrogen in its molecules, it is highly resistant to chlorinee bleaching, oxygen bleaching, strong acids, and alkali, and has excellent sweat stain resistance. This makes optical brightener CBS-X highly effective in bleaching-resistant detergents.
It has excellent dry and wet light fastness and that makes it more effective in actual usage. In contrast, DSA acid-type fluorescent whitening agents are mostly decomposed by sunlight during fabric drying
It can significantly increase the whiteness of laundry powder, soap, and detergent, and improve their appearance.
It has extremely low toxicity and it ensures high safety for human use and operation.
It is a sulfonated stilbene derivative and compatible with most other detergent ingredients. It does not affect the performance of enzymes or other additives

What is Optical brightener CBS-X?
Optical brightener CBS-X is a type of fluorescent whitening agent used in the synthetic industry and textile industry to enhance the brightness and whiteness of fabrics. It is also commonly known as fluorescent brightening agent FB-351 or fluorescent brightener CF-351. It absorbs ultraviolet light and emits blue light, which makes the fabric appear brighter and whitener. It is often used in laundry detergents, fabric softeners, and other cleaning products to improve the visual appearance of clothing and textiles. Additionally, fluorescent whitening agent CBS-X is a safe and effective ingredient that is widely used in the synthetic and textile industry around.
How does Optical brightener CBS-X works?
Fluorescent Whitening Agent CBS-X ,also known as Tinopal CBS-X and FB-351 ,is a type of optical brightener or fluorescent whitening agent (FWA) that is used to enhance the brightness and whiteness of various materials, including textiles and detergents.
FWAs absorb ultraviolet light and re-emit it as blue light, which creates a "whiter-than-white" effect by increasing the amount of blue light reflected from the material. FB-351 is a highly effective FWA that is commonly used in laundry detergents, fabric softeners, and other laundry products to improve the whiteness and brightness of textiles.
What is the advantage of CBS-X?
CBS-X is typically added in laundry detergents and fabric softeners in small amounts and usually less than 0.5% by weight. It is compatible with a wide range of detergent formulations and can be used in both liquid and powder detergents.
Some of the benefits of using FB-351 in laundry products include improved whiteness and brightness of fabrics, enhanced color contrast, and increased consumer appeal. It is also relatively stable under normal storage and usage conditions, which makes it a popular choice for synthetic detergent manufacturers and factories.
