Description

Tripotassium 3,3',3''-(1,3,5-Triazine-2,4,6-Triyltriimino)Tris(Benzenesulphonate) is a high-purity, water-soluble organic salt derived from a triazine-based fluorescent whitening agent (FWA). This compound is valued for its exceptional ability to absorb ultraviolet light and re-emit it as visible blue light, thereby enhancing the perceived whiteness and brightness of materials. It is a critical performance additive for manufacturers in the textile, paper, detergent, and plastics industries seeking to achieve superior optical brightening effects. The product is supplied with a CAS number of 94236-89-2.

Application

This optical brightening agent (OBA) is engineered for high-performance applications where brilliant whiteness and color correction are paramount.

• Textile Finishing: Applied to cotton, polyester, nylon, and blended fabrics to compensate for yellowish tints and achieve a clean, bright white appearance.
• Paper Manufacturing: Incorporated into pulp or coatings for high-quality writing, printing, and specialty papers to enhance brightness and opacity.
• Detergent & Laundry Care: A key component in premium laundry detergents, fabric softeners, and soaps to make white fabrics appear whiter and colors more vibrant after washing.
• Plastics and Polymers: Used as an additive in the production of plastics, synthetic fibers, and films to improve initial whiteness and counteract yellowing.
• Cosmetics and Personal Care: Employed in formulations like shampoos, conditioners, and skin creams to impart a bright, clean visual profile.
• Advanced Material Coatings: Utilized in paints, inks, and varnishes to achieve specific optical properties and improve aesthetic quality.

Quality Control

Our production of Tripotassium 3,3',3''-(1,3,5-Triazine-2,4,6-Triyltriimino)Tris(Benzenesulphonate) adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing to ensure consistent purity, performance, and compliance with industry specifications. A detailed Certificate of Analysis (COA), documenting key parameters such as assay, absorbance, and impurity profiles, is provided with each shipment to guarantee reliable quality and traceability for our B2B partners.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance and handling.
