Description

Fluorescent Brightener 230 CAS NO 68444-86-0 is a high-performance stilbene-based optical brightening agent (OBA) designed to enhance the whiteness and brightness of various substrates. This compound is critical for manufacturers seeking to achieve superior visual appeal and perceived cleanliness in their products under UV or daylight illumination. It is primarily utilized by the paper, textile, detergent, and plastics industries to correct yellowness and impart a brilliant blue-white fluorescence.

Application

• Paper Manufacturing: Key for high-grade writing, printing, and tissue papers to achieve exceptional brightness and opacity.
• Textile Finishing: Used in the bleaching and finishing of cotton, nylon, and polyester fabrics to improve whiteness.
• Laundry Detergents & Fabric Softeners: Incorporated as a key additive to make white fabrics appear brighter and colors more vivid after washing.
• Plastics and Synthetic Fibers: Applied during polymer processing to brighten masterbatches, films, and molded articles.
• Soaps and Personal Care Products: Enhances the visual appeal of bar soaps, liquid soaps, and cosmetic formulations.
• Coatings and Paints: Used in specific coating formulations to improve brightness and masking power.
