| Cosmetics Industry | Used as a colorant ingredient | Incorporated into cosmetic formulations via controlled dispersion and stabilization processes |
Manufacturing Quality Control of ACID BLUE 29
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantitative determination based on absorbance at characteristic wavelength (lambda-max ~620 nm) using molar absorptivity and Beer-Lambert law. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration measuring water content via iodine-sulfur dioxide reaction in pyridine/methanol medium. |
| Inorganic Salts (Ash Content) | Gravimetric Analysis (Ignition Method) | Sample ignited at 550-600 C to oxidize organic matter; residual inorganic ash weighed after cooling in desiccator. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Multi-element quantification by measuring atomic emission intensities of plasma-excited elements after acid digestion. |
| Chloride Ion | Potentiometric Titration with AgNO3 | Titration using silver nitrate and silver indicator electrode; endpoint detected by potential jump upon AgCl precipitation. |
| pH of 1% Aqueous Solution | pH Meter Measurement | Electrochemical measurement of hydrogen ion activity in standardized aqueous dispersion using calibrated glass electrode. |
| Water Solubility | Visual Inspection and Filtration | Sample dispersed in distilled water at 25 C; solubility assessed by absence of undissolved particles after filtration and visual clarity. |
| Organic Impurities (Related Substances) | HPLC-UV | Separation on reversed-phase column followed by UV detection; impurities quantified relative to main peak using external standard or area normalization. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles in liquid medium to calculate volume-based size distribution. |
| Bulk Density | Graduated Cylinder Method | Mass of sample freely poured into calibrated cylinder divided by its settled volume; measured under standardized conditions. |
| Color Strength (Relative) | UV-Vis Spectrophotometry | Comparison of absorbance ratio (sample vs. reference standard) at lambda-max, normalized to same concentration and path length. |
| Residue on Ignition | Gravimetric Analysis | Weight loss on ignition at 700 C for 30 min; residue mass expressed as percentage of original sample weight. |
