Description

Fluorescent Brightener 86 is a high-performance stilbene derivative optical brightening agent (OBA) designed to enhance the whiteness and brightness of various substrates. Its core value lies in its ability to absorb ultraviolet light and re-emit it as visible blue light, effectively counteracting yellowing and creating a visually brighter, cleaner appearance. This product is essential for manufacturers in the plastics, synthetic fibers, detergents, and paper industries seeking to improve the aesthetic appeal and perceived quality of their finished goods. Fluorescent Brightener 86 CAS NO 12224-07-6 is known for its excellent compatibility and stability in polymer matrices and formulations.

Application

• Plastics and Polymers: Widely used in the mass coloration of polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), and ABS to achieve brilliant whiteness.
• Synthetic Fibers: Effective for brightening polyester, nylon, and acetate fibers during spin-dyeing or in finishing baths.
• Detergents and Laundry Care: Incorporated into laundry detergents, fabric softeners, and soaps to impart a "whiter-than-white" effect to textiles.
• Paper and Board: Used in coating formulations and pulp to enhance the brightness of high-quality writing, printing, and packaging papers.
• Coatings and Inks: Added to paints, lacquers, and printing inks to improve optical brightness and clarity.
• Personal Care Products: Employed in certain cosmetics and personal care items where a brightening effect is desired.
