| Industry | Application | Process |
|---|---|---|
| Textile Dyeing & Printing | Fluorescent brighteners and colorants | Added as fluorescent dyes during dyeing or printing of synthetic fibers (e.g., polyester, nylon) and fixed onto fibers via high-temperature, high-pressure dyeing or thermosol dyeing processes |
| Plastics Processing | Fluorescent colorants | Blended with plastic resins (e.g., polyethylene, polypropylene, polystyrene) and incorporated into finished products with bright blue fluorescence during injection molding, extrusion, or other shaping processes |
| Ink Manufacturing | Fluorescent ink component | Formulated into fluorescent inks for packaging, security, or decorative printing and applied via screen printing, gravure printing, or other printing processes |
| Coatings Industry | Fluorescent coating additive | Added to solvent-based or water-based coatings to produce high-visibility safety coatings or decorative fluorescent coatings |
| Household & Personal Care Products | Fluorescent whitening agents | Used in trace amounts in detergents or fabric softeners to enhance the visual whiteness and brightness of white or light-colored textiles |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by retention time and UV absorbance relative to certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities using gradient elution and UV detection. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration with iodine-based reagent. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by weight measurement. |
| Heavy Metals | ICP-OES | Quantifies Pb, Cd, Hg, As, and other metals by plasma excitation and elemental emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Turbidimetry | Measures sulfate as barium sulfate precipitate formation and light scattering intensity. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines hydrogen ion activity using calibrated glass electrode in 1% w/v aqueous suspension. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution by measuring angular variation in laser light scattering from dispersed particles. |
| Bulk Density | USP <616> Tap Density Test | Measures mass per unit volume after controlled mechanical tapping of a powder sample. |
| Loss on Drying | Thermogravimetric Analysis | Quantifies volatile content by mass loss upon heating at 105 C under controlled atmosphere. |
| Microbial Limits | Membrane Filtration | Detects aerobic microorganisms by filtration, membrane transfer to agar media, and colony enumeration. |
