For Research & Development scientists and product formulators, a detailed understanding of chemical properties is crucial for successful product development. Fluorescent Brightener 85 (CAS 12224-06-5) is a versatile optical brightening agent, and knowing its technical specifications allows for optimized application in textiles, paper, and detergents. As a reputable supplier, we aim to equip you with the necessary information to effectively buy and utilize this compound.

Fluorescent Brightener 85 is characterized by its molecular formula C36H34N12Na2O8S2 and a molecular weight of approximately 872.84. Visually, it appears as a light yellow or yellow powder. Its functionality as an optical brightener stems from its ability to absorb ultraviolet light and emit visible blue light, thereby enhancing the whiteness and brightness of treated materials. This process is fundamental to achieving the desired aesthetic in many consumer and industrial products. For those looking to purchase this brightener, understanding its chemical structure and physical form is the first step.

Key technical properties relevant to its application include its solubility, ionic type, and stability. Fluorescent Brightener 85 is an anionic surfactant, making it compatible with various aqueous systems. It demonstrates good stability across a range of pH levels, typically performing optimally in neutral to slightly alkaline conditions (pH 8-9). Its acid resistance up to pH 6 and alkali resistance up to pH 11 highlight its robustness. Furthermore, it is resistant to hard water (up to 300ppm) and has a degree of free chlorine resistance, which are important considerations for laundry and papermaking applications. These properties make it a reliable choice for manufacturers seeking a high-performance brightener.
