Industrial Applications of Sodium Stearyl Fumarate
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Lubricant for tablets and capsules | Used as a glidant and lubricant in solid dosage form manufacturing to improve powder flowability and prevent sticking during compression |
| Food | Food additive (anti-caking agent) | Applied in powdered food products to prevent caking and enhance flowability and dispersibility |
| Cosmetics | Cosmetic ingredient (lubrication and stabilization) | Incorporated into products such as pressed powders and talcum powders to provide lubricity and improve product stability |
| Plastics | Polymer processing aid | Used as a mold release agent or lubricant to improve demolding performance during plastic molding |
Manufacturing Quality Control of Sodium Stearyl Fumarate
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification | Infrared Spectroscopy (IR) | Compare the sample spectrum with a reference standard spectrum, matching characteristic absorption peaks (e.g., C=O, C-O, O-H) to confirm molecular structure consistency. |
| High-Performance Liquid Chromatography (HPLC) | Confirm consistency between the main component and reference standard by comparing retention times; used for identification and purity analysis. | |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase column (e.g., C18) with a UV detector (approximately 220 nm) to determine the content of the main component via external or internal standard methods. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying Method | Dry the sample at 105°C until constant weight is achieved; calculate the percentage weight loss to control moisture and volatile impurities. |
| Residue on Ignition (Ash) | Sulfated Ash Method | Incinerate the sample at high temperature, treat with sulfuric acid, and measure the weight of residual inorganic matter to assess inorganic impurity content. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Digest the sample and determine the concentrations of heavy metal elements such as lead, arsenic, cadmium, and mercury, ensuring compliance with pharmacopoeial limits. |
| Microbial Limits | Microbial Limit Test (Chinese Pharmacopoeia) | Test for total aerobic microbial count, total mold and yeast count, and specified control organisms (e.g., Escherichia coli, Salmonella spp.). |
| Particle Size Distribution | Laser Diffraction Particle Size Analysis | Measure particle size distribution using laser scattering principles to ensure proper flowability and tabletting performance as an excipient. |
| Tap Density and Bulk Density | Cylinder Method (USP <616>) | Determine the loose bulk density and tapped density; calculate Hausner ratio and compressibility index to evaluate flow properties. |
| pH | pH Measurement Method | Dissolve the sample in water or an appropriate solvent and measure the pH value using a pH meter to control acidic or basic impurities. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Use gradient elution to detect possible synthetic intermediates, degradation products, and other organic impurities; calculate total impurity content. |
| Chlorides | Silver Nitrate Turbidimetric Method | Add silver nitrate in a nitric acid medium to form silver chloride turbidity; quantify chloride ion content by turbidimetry. |
| Sulfates | Barium Chloride Turbidimetric Method | Add barium chloride in a hydrochloric acid medium to form barium sulfate precipitate; determine sulfate content by turbidimetry. |
