Optical Brightening Agent CXT (also known scientifically as Fluorescent Whitening Agent CXT, or FWA CXT) is an anionic, bistriazinylamino stilbene derivative designed specifically for the high-end brightening of cellulosic fibers, paper pulps, and detergent formulations. In chemical terms, OBA CXT works by absorbing invisible ultraviolet radiation (predominantly in the wavelength range of 340–380 nm) and re-emitting it as visible blue light in the 400–450 nm spectrum. This blue emission compensates for the natural yellowish tint inherent in unbleached natural fibers and synthetic substrates, resulting in a perceived increase in whiteness and brightness to the human eye.
Features exceptional resistance to high-temperature processing environments, acid-alkali shifts during sizing, and hydrogen peroxide bleaches.
Exhibits superior affinity for cellulose fibers, enabling high exhaustion rates in textile dye baths and rapid absorption in wet-end paper mills.
Fully compliant with ZDHC Level 3, meaning it is formulated to prevent toxic build-ups, heavy metal contamination, and bio-accumulative risks.
Compared to lower-tier brightening agents, OBA CXT offers high whitening intensity, low dosage requirements, and excellent dispersion properties in liquid systems. It is highly soluble in warm water, which facilitates ease of application and prevents the formation of specks or uneven spots on the treated textile or paper surfaces.
The global chemical manufacturing sector relies heavily on raw material cost-efficiency and volume security. Purchasing OBA CXT directly from a major Chinese producer like Tianjin Sunrise Chem Group offers significant economic advantages:
A Message to Global Procurement Officers: By cutting out middleman brokers, Sunrise Chem offers direct-factory pricing, customizable active-ingredient concentrations (from standard powder formats to high-density liquid forms), and reliable delivery lead times. This allows you to streamline your supply chain and reduce operational overhead.
OBA CXT is a highly versatile brightener used across multiple industries. Its performance profile matches a variety of demanding applications:
OBA CXT is widely used in both heavy-duty powder detergents and modern liquid laundry detergents. It exhibits strong resistance to chlorine bleaches and peroxide oxidizers. Its high solubility ensures it remains fully dissolved in liquid formulations without phase separation, leaving fabrics looking brighter after washing.
In textile finishing, OBA CXT works via continuous padding or exhaust dyeing of cotton, linen, and cellulose-blend fabrics. It features an exhaust rate that aligns well with standard industrial dye cycles, allowing mills to achieve high whiteness values without using excess energy or chemical inputs.
For paper manufacturing, OBA CXT can be added at the wet-end during pulp preparation or applied at the size press. It binds strongly to cellulose fibers, minimizing run-off into whitewater loop systems. The result is bright, high-contrast printing paper with low yellowing tendencies.
Our technical team can customize OBA CXT formulations to meet specific active concentration requirements, helping you achieve optimal performance at a lower cost per ton.
Environmental protection is the cornerstone of our innovation. We dedicate ourselves to providing clients with eco-friendly, high-quality colorants that balance productivity with environmental harmony, driving the industry toward a more sustainable development path while delivering high-performance products—for a greener textile industry and a sustainable future.
The ZDHC (Zero Discharge of Hazardous Chemicals) program is a collaborative effort by leading brands, retailers, and suppliers in the textile and footwear industry to eliminate hazardous chemicals. Achieving ZDHC Level 3 certification indicates that our company has implemented robust chemical management procedures and has met the most stringent global requirements for chemical handling, wastewater treatment, and pollution prevention. This guarantees that no restricted substances are used in our synthesis lines.
Similarly, the Global Organic Textile Standard (GOTS) is the leading worldwide processing standard for textiles made from organic fibers. It defines high-level environmental criteria along the entire organic textiles supply chain and requires compliance with social criteria as well. GOTS certified products are widely recognized as sustainable, safe, and ethical. By choosing Sunrise Chem as your OBA CXT manufacturer, you can rest assured that your raw materials will comply with the environmental standards of top-tier consumer brands in North America and the European Union.
The global market for optical brighteners is shifting toward higher eco-compliance and liquid-formulation solutions. Manufacturers are moving away from traditional powder formats due to occupational safety concerns related to workplace dust inhalation. To address this, Sunrise Chem has expanded production of low-dust granules and highly stable liquid OBA forms.
Furthermore, wastewater treatment regulations have led mills to demand optical brighteners with higher exhaust rates and better fiber affinity. Lower affinity agents leave active chemicals in the effluent, increasing the chemical oxygen demand (COD) in wastewater treatment plants. OBA CXT from Sunrise Chem is engineered to bind rapidly to cellulosic substrates, helping mills reduce wastewater treatment costs while maintaining consistent product quality.
