Optical brighteners are a fascinating class of chemical compounds that enhance the visual appeal of various materials by increasing their perceived whiteness and brightness. Among these, Optical Brightener BA (CAS 12768-92-2), also known as Fluorescent Brightener 113, stands out due to its exceptional properties and wide-ranging applications. As a dedicated supplier of chemical auxiliaries, we aim to provide manufacturers with a clear understanding of its benefits and uses.

Optical Brightener BA is characterized by its water solubility, excellent light fastness, and strong resistance to common processing chemicals like acids, alkalis, and hydrogen peroxide. Chemically, it is a stilbene triazine disulfonic sodium derivative. This specific chemical structure allows it to efficiently absorb ultraviolet radiation (typically in the 340-370 nm range) and re-emit it as visible light in the blue spectrum. This re-emitted light compensates for the natural yellowing that materials may exhibit, resulting in a brighter, cleaner white appearance.

The versatility of Optical Brightener BA is a major advantage for manufacturers. Its applications span across several key industries:

  • Textiles: Used in various stages of textile processing to whiten natural and synthetic fibers like cotton and polyester, improving the brightness of finished fabrics.
  • Paper: Incorporated into paper pulp, surface sizing, and coating to enhance paper brightness, making printed materials more vivid and appealing.
  • Plastics: Added to plastic formulations to restore whiteness and counteract yellowing caused by UV exposure or manufacturing processes, crucial for packaging and consumer goods.
  • Detergents: A key ingredient in laundry detergents to make clothes appear whiter and brighter by depositing onto fabrics and reflecting more visible light.
