Optical brightening agents (OBAs) are chemical compounds that are used to enhance the brightness and whiteness of materials such as textiles, paper, detergents, and plastics. They work by absorbing ultraviolet light and re-emitting it as visible blue light. This helps enhance their visual appeal and makes the products stand out on the shelf. It is worth noting that optical brighteners are not permanent and can fade over time. They may also be less effective in materials that are exposed to direct sunlight or other sources of UV light. When using products containing optical brighteners, it is important to follow the manufacturer's instructions regarding dosage and application methods to achieve the desired effect.

Used in cotton fabric dyeing process. The aqueous solution is milky white suspension, but it does not affect the use effect. The maximum white point of CXT is much higher than that of other optical brighteners, and satisfactory results can be obtained by using CXT for cotton fabrics requiring very high whiteness. Optical brightener agent CXT is also suitable for the soap and cleaning manufacturing industry. High whiteness, strong fluorescence, white light.

Dosage: Dip dyeing 0.2-0.4% (o.w.f)
