Description

Fluorescent Brightener 24 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 improving the perceived brilliance and color quality of finished products. This agent is essential for manufacturers in the detergent, paper, textile, and plastics industries seeking to achieve superior visual appeal and market competitiveness for their goods.

Application

• Laundry Detergents & Fabric Softeners: Incorporated into powder and liquid formulations to make white fabrics appear brighter and colors more vibrant after washing.
• Paper & Pulp Industry: Used in the coating and sizing of high-quality writing, printing, and packaging papers to achieve a high degree of whiteness and opacity.
• Textile Finishing: Applied in the finishing baths for cotton, nylon, and other synthetic fibers to compensate for natural yellowness and improve the brightness of white textiles.
• Plastics and Synthetic Fibers: Added during the polymerization or compounding process for polymers like PVC, polyolefins, and polyesters to enhance the whiteness of the final plastic products or fibers.
• Soaps and Personal Care Products: Used in certain bar soaps and cosmetic formulations where a bright, clean visual appearance is desired.
