In the chemical industry, precise specifications and understanding the nuances of each compound are critical for successful product development and manufacturing. Optical Brightener CBS-X, identified by its CAS number 27344-41-8, is a prime example of a specialty chemical that offers significant advantages across various applications, particularly in detergents and textiles. As a leading manufacturer, we aim to provide comprehensive information on this vital ingredient.

Decoding CAS 27344-41-8: Optical Brightener CBS-X

Optical Brightener CBS-X, chemically known as Disodium 4,4'-bis(2-sulfostyryl)biphenyl, is a synthetic organic compound belonging to the distyrylbiphenyl class of optical brighteners. Its molecular formula is C28H20Na2O6S2, and it typically presents as a yellow crystalline powder. The core function of CBS-X is its ability to absorb ultraviolet radiation (UV light) in the 348-350 nm range and re-emit this energy as visible blue fluorescence. This phenomenon effectively masks any inherent yellowness in materials, thereby enhancing their perceived whiteness and brightness.

Key Physicochemical Properties and Their Significance:

  • Appearance: Typically a Yellow Powder. This visual characteristic is common for many optical brighteners.
  • E(1%/cm) Value: Ranges from 1105-1180, indicating high fluorescence intensity and thus superior whitening power. This is a critical metric for formulators.
  • Solubility: Exhibits high solubility in water, making it exceptionally easy to formulate into aqueous systems common in detergents and textile finishing baths. Its solubility is around 17.6 g/L at 20°C.
  • Purity: High purity levels, often 99.5% min, ensure consistent performance and minimize unwanted side reactions in formulations.
  • Stability: Features outstanding stability, including resistance to chlorine and oxygen bleaching, as well as to strong acids and alkalis. This makes it robust for use in demanding chemical environments.
  • Lightfastness: Possesses good photostability, meaning the whitening effect remains effective even after exposure to light.
  • Affinity to Cellulosic Fibers: Demonstrates high affinity, leading to high exhaustion rates during application on cotton and other cellulosic materials, and importantly, it avoids the 'greening' effect after repeated washings.

Why Manufacturers Seek Quality CAS 27344-41-8

For detergent manufacturers and textile processors, sourcing Optical Brightener CBS-X with consistent high purity and stability is crucial. These properties directly impact the final product's performance, aesthetic appeal, and brand reputation. When you buy Optical Brightener CBS-X, you are investing in a critical component that differentiates your product. Understanding the detailed specifications, such as the E-value and solubility, allows formulators to optimize dosages and achieve the desired visual impact efficiently.
