Manufacturing Quality Control of ZINC BENZOATE
| Test Item | Common Testing Method | Method Description |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, state, and presence of visible foreign matter under natural light or a standard light source. Typically appears as white or off-white powder. |
| Identification | Infrared Spectroscopy (IR) | Compare the sample with reference spectra to confirm the structure of benzoic acid zinc salt by characteristic absorption peaks (e.g., carboxylate, aromatic rings). |
| Ultraviolet-Visible Spectrophotometry (UV-Vis) | Characteristic absorption peaks appear near 230 nm and 275 nm for benzoic acid, used for auxiliary identification. | |
| Content Determination | Complexometric Titration (EDTA Titration) | In a pH 5–6 buffer solution, titrate zinc ions using EDTA standard solution with xylenol orange as an indicator to calculate the content of benzoic acid zinc. |
| High-Performance Liquid Chromatography (HPLC) | Separte and quantify benzoate ions; combine with zinc content to calculate total content; suitable for high-precision quantitative analysis. | |
| Moisture | Karl Fischer Method | Iodine reacts with sulfur dioxide in an anhydrous environment to accurately determine water content in the sample. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Method | Dry at 105°C until constant weight to measure mass loss and evaluate the content of crystallization water or volatile components. |
| Residue on Ignition | Ignition Method | Ignite the sample at high temperature (approximately 600–800°C) to determine the amount of non-volatile inorganic residue, mainly reflecting inorganic salt impurities. |
| Heavy Metals | Atomic Absorption Spectrometry (AAS) | Dissolve the sample and measure the content of heavy metals such as lead, cadmium, mercury, and arsenic to ensure compliance with pharmacopoeia or safety standards. |
| pH Value | pH Meter Method | Prepare a water suspension of specified concentration (e.g., 1%) and measure its acidity or alkalinity using a pH meter to determine if it meets the specified range. |
| Chlorides | Silver Nitrate Turbidity Method | Add silver nitrate in nitric acid medium to form turbid silver chloride precipitate, compare with a standard reference solution to control chloride ion impurities. |
| Sulfates | Barium Chloride Turbidity Method | Add barium chloride in hydrochloric acid medium to form barium sulfate precipitate, use turbidity method to control sulfate ion impurities. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Separate benzoic acid, unreacted raw materials, or other organic impurities using a reverse-phase chromatography column to assess purity and impurity limits. |
| Microbial Limit | Microbial Limit Test | Conduct aerobic bacterial count, mold and yeast count, and control bacteria (e.g., Escherichia coli) testing according to the Chinese Pharmacopoeia or relevant standards. |
