Industrial Applications of Pergascript Red I 6B
| Industry | Application | Process |
|---|---|---|
| Food Industry | Used as a red food colorant in beverages, confectionery, dairy products, etc. | Directly added to the food matrix; used within the limits specified in GB 2760-2014. |
| Cosmetics Industry | Used as a colorant in color cosmetics such as lipsticks and blushes. | Melt-blended with oil- and wax-based matrices, followed by cooling and molding or compression molding. |
| Pharmaceutical Industry | Used for coloring coatings of oral solid dosage forms (e.g., tablets, capsules). | Applied via wet or dry coating processes; pigment dispersion is sprayed onto the tablet or capsule core surface. |
Manufacturing Quality Control of Pergascript Red I 6B
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies main component concentration via absorbance at characteristic λ_max (typically ~520 nm) using molar absorptivity and Beer-Lambert law. |
| Loss on Drying (LOD) | Gravimetric Analysis (Thermogravimetry) | Measures mass loss after drying at 105 °C to determine volatile content including moisture and residual solvents. |
| Heavy Metals (as Pb) | ICP-OES | Simultaneously quantifies trace heavy metals (Pb, As, Cd, Hg) by plasma-induced atomic emission spectroscopy after acid digestion. |
| Residual Solvents (e.g., Methanol, Acetone) | Gas Chromatography (GC-FID) | Separates and quantifies volatile organic solvents using capillary column and flame ionization detection. |
| pH (1% aqueous solution) | Potentiometric Titration | Determines hydrogen ion activity in aqueous dispersion using calibrated pH electrode and standardized buffer reference. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemically determines trace water via iodine generation and stoichiometric reaction with water in anhydrous medium. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of dispersed particles in liquid medium based on angular dependence of scattered laser light intensity. |
| Color Value (Absorbance Ratio) | UV-Vis Spectrophotometry | Evaluates batch consistency by comparing absorbance at λ_max to absorbance at a secondary wavelength (e.g., A₅₂₀/A₆₀₀). |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Determines inorganic residue after combustion with sulfuric acid treatment and high-temperature incineration (550–600 °C). |
