| Cosmetics | Ingredient | Used to enhance product smoothness and stability |
Manufacturing Quality Control of 1,2,4-Benzenetricarboxylic acid, tripropyl ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to internal/external standard using calibrated response factors. |
| Acid Value | Acid-Base Titration with KOH in ethanol | Measures free carboxylic acid content by titration with standardized potassium hydroxide solution. |
| Water Content | Karl Fischer Coulometric Titration | Determines trace water via electrochemical iodine generation proportional to water in sample. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Evaluates yellowness by comparing sample absorbance at 455 nm to APHA platinum-cobalt standards. |
| Density at 20 C | Digital Density Meter (Oscillating U-tube) | Measures mass per unit volume based on resonant frequency shift of vibrating U-tube filled with sample. |
| Refractive Index at 20 C | Abbe Refractometer | Determines ratio of light velocity in air vs. sample by measuring critical angle of total internal reflection. |
| Residue on Ignition | Gravimetric Analysis after High-Temperature Ashing | Measures non-volatile inorganic impurities as weight remaining after combustion at 700-800 C. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet digestion | Quantifies total heavy metals by atomization and absorption measurement at element-specific wavelengths. |
| Chlorinated Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and quantifies chlorinated by-products based on retention time and characteristic mass fragments. |
| Volatility Residue (Loss on Drying) | Thermogravimetric Analysis (TGA) or Oven Drying at 105 C | Measures weight loss after controlled heating to remove volatile components including solvents and low-MW impurities. |
| Hydrolyzable Chloride | Potentiometric Titration with AgNO3 | Detects chloride ions released upon acid hydrolysis by silver nitrate titration with silver indicator electrode. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light induced by chiral impurities or degradation products in solution. |
