Industrial Applications of FOOD BLUE NO. 1 ALUMINUM LAKE
| Industry | Application | Process |
|---|---|---|
| Cosmetics | Pigment colorant providing blue hues in products such as eyeshadow, lipstick, and nail polish | Disperse Acid Blue 9 aluminum lake in cosmetic matrices via grinding and homogenization to produce stable color dispersions |
| Plastics Processing | Colorant for plastic products, used to color polyolefins, polystyrene, and other plastic materials | Incorporate the lake pigment into the molten polymer during extrusion, followed by thorough mixing to achieve uniform coloration |
| Ink Manufacturing | Provides high-stability blue in printing inks, including gravure and screen inks | Mix the lake pigment with resins, solvents, and other components via grinding and dispersion to formulate stable ink systems |
| Textile Printing & Dyeing | Used for textile printing or dyeing to deliver blue shades with excellent lightfastness and washfastness | Formulate printing pastes by combining the lake pigment with binders and auxiliaries for direct or pigment printing processes |
| Pharmaceutical Excipients | Colorant in pharmaceutical formulations, used in capsule shells and tablet coatings | Blend the lake pigment with excipients during tablet compression or capsule coating operations |
Manufacturing Quality Control of FOOD BLUE NO. 1 ALUMINUM LAKE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Color Strength | UV-Vis Spectrophotometry | Measures absorbance at lambda-max (approx. 630 nm) relative to certified reference standard to quantify dye concentration. |
| Moisture Content | Karl Fischer Titration | Quantifies water content via coulometric or volumetric titration using iodine-based reagent. |
| Ash Content | Gravimetric Analysis | Determines inorganic residue after high-temperature incineration (550-600 C) and weighing. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously quantifies trace metals after acid digestion by measuring element-specific atomic emission intensities. |
| Chloride Content | Potentiometric Titration | Measures chloride ions using silver nitrate titrant and silver/silver chloride electrode endpoint detection. |
| pH of Aqueous Suspension | pH Meter Measurement | Determines pH of 1% w/v aqueous dispersion using calibrated glass electrode. |
| Particle Size Distribution | Laser Diffraction | Analyzes scattered laser light intensity vs. angle to calculate volume-based particle size distribution. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies structurally related compounds using reversed-phase chromatography and UV detection. |
| Aluminum Content | Complexometric Titration | Titrates Al3+ with EDTA at controlled pH using xylenol orange indicator for endpoint. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., toluene, xylene) using flame ionization detection. |
| Bulk Density | Tap Density Measurement | Determines mass per unit volume after standardized mechanical tapping of a known powder mass. |
| Filterability | Vacuum Filtration Test | Evaluates suspension stability and filtration rate under standardized vacuum conditions using defined filter medium. |
