Optical Brightening Agent CBS-P

Product Overview

Optical Brightening Agent CBS-P represents a premium class of stilbene-derived fluorescent whitening agents engineered for high-efficiency industrial applications. As a critical functional additive, this compound operates by absorbing ultraviolet light and re-emitting it as visible blue fluorescence, effectively neutralizing yellow tones in substrates. This process results in a perceptible increase in whiteness and brightness, making it an indispensable component in modern cleaning formulations. Our manufacturing process ensures high purity and consistent performance across batches, meeting the rigorous demands of global detergent producers.

The chemical structure, identified as 4,4'-bis(2-sodium sulfonate styryl) biphenyl, provides exceptional stability under various washing conditions. Unlike generic brighteners, CBS-P offers superior compatibility with anionic and nonionic surfactant systems commonly found in heavy-duty cleaning products. This compatibility ensures that the brightening effect remains stable throughout the product shelf life and during the washing cycle, providing end-users with visibly cleaner and brighter fabrics.

Key Performance Features

• Exceptional solubility in water, facilitating easy integration into liquid and powder detergent matrices.
• High whitening efficiency with a significant E-value, ensuring optimal performance at low dosage rates.
• Robust stability against chlorine and peroxide bleaching agents often present in industrial cleaners.
• Free from ammoniacal odors, ensuring a neutral and pleasant profile in the final consumer product.
• Consistent greenish-yellow granular appearance indicating high chemical purity and lack of degradation.

Technical Specifications

Industrial Applications

This optical brightener is primarily utilized in the production of high-grade detergent powders and liquid detergents. It is especially suitable for industrial detergent formulations where consistent whiteness and brightness are key quality indicators. The recommended dosage typically ranges from 0.04% to 0.2% by weight of the detergent, depending on the desired level of brightness and the specific formulation matrix. Incorporating CBS-P into your detergent formula enhances the visual appeal of washed textiles, providing a competitive advantage in the consumer market.

Beyond household laundry, this chemical finds application in institutional cleaning supplies and textile processing aids where optical enhancement is required. Its nonionic character allows for versatile use across different pH ranges, making it a flexible choice for formulators developing specialized cleaning solutions. The product delivers fast whitening ability, reaching high whiteness levels within a short washing time, which is crucial for industrial laundry operations.

Packaging and Storage

To maintain chemical integrity, Optical Brightening Agent CBS-P is packaged in 25kg bags, 25kg cartons, or 500kg bulk bags according to customer requirements. The product has a shelf life of two years when stored under room temperature conditions. It is essential to avoid exposure to strong sunlight and wet environments during storage to prevent degradation of the fluorescent properties. Proper handling ensures that the material retains its specified E-value and solubility characteristics until use.
