Description

Fluorescent Brightener 30 is a high-performance stilbene-based 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 perceived visual appeal. This product is essential for manufacturers in the detergent, paper, textile, and plastics industries seeking to achieve superior product aesthetics and market competitiveness.

Application

• Laundry Detergents & Fabric Softeners: Incorporated to make white fabrics appear brighter and colors more vivid after washing.
• Paper & Pulp Manufacturing: Used in coatings and mass to achieve high-brightness, blue-white paper for printing, writing, and packaging grades.
• Textile & Fiber Treatment: Applied in finishing baths for synthetic fibers (like polyester and nylon) and cotton to improve whiteness.
• Plastics & Polymer Processing: Added to polymers such as PVC, polyethylene, and polystyrene to correct inherent yellowness and enhance brightness.
• Soaps and Personal Care Cleansers: Utilized to boost the visual appeal of bar soaps, liquid hand washes, and other cleansing products.
• Coatings and Inks: Formulated into specific coatings and inks where optical brightening is required for special visual effects.
