Product Technical Details

Product Overview

Optical Brightening Agent CBS-X represents a premier class of fluorescent whitening agents specifically engineered for the modern hygiene and cleaning industry. As a disulfonic acid derivative, this compound is renowned for its exceptional ability to absorb ultraviolet light and re-emit it as visible blue light, effectively masking yellow tones in fabrics and surfaces. Our premium grade CBS-X is manufactured under strict quality control protocols to ensure consistent performance across diverse industrial applications. The granular form factor significantly reduces dust generation during handling, promoting a safer working environment for production staff while maintaining high solubility rates in aqueous solutions.

Key Performance Features

  • Superior Whitening Effect: Delivers outstanding initial whiteness and maintains brightness through multiple wash cycles, preventing the greyish cast often associated with lower quality brighteners.
  • Exceptional Stability: Exhibits robust resistance to acid, alkaline, chlorine, and oxidative environments, making it ideal for use in bleaching detergent formulations.
  • Dust-Free Handling: The granulated physical form minimizes airborne particles, reducing inhalation risks and ensuring cleaner production facilities.
  • High Solubility: Rapidly dissolves in water at standard temperatures, ensuring uniform distribution in liquid and powder detergent matrices without residue.
  • Safety Profile: Free from ammoniacal odours and harmful impurities in water solution, aligning with modern environmental and safety standards.

Industrial Applications

This versatile brightening agent is primarily utilized in the manufacturing of household and industrial cleaning products. It is highly compatible with soap bars, laundry detergent powders, and liquid detergent systems. The recommended dosage typically ranges from 0.04% to 0.2% by weight relative to the detergent base, depending on the desired level of brightness and the specific formulation constraints. Beyond laundry care, CBS-X finds application in textile processing where enhanced whiteness is a critical quality attribute. Its compatibility with various surfactant systems allows formulators to achieve high-performance results without compromising the stability of the final product.

Packaging and Storage

To preserve product integrity, Optical Brightening Agent CBS-X is packaged in durable 25kg bags, 25kg cartons, or 500kg bulk bags, with custom packaging solutions available upon request. The material should be stored in a cool, dry environment at room temperature, strictly avoiding direct sunlight and moisture exposure which could degrade performance. Under proper storage conditions, the product maintains a shelf-life of up to two years. We provide comprehensive technical documentation, including Certificates of Analysis (COA), to support quality assurance processes for our global manufacturing partners.
