Industrial Applications of METHYL STEARATE
| Industry | Application | Process |
|---|---|---|
| Cosmetics | Emollient, emulsion stabilizer, thickener | Incorporated into formulations for creams, lotions, and lipsticks as an oil-phase component, blended with other oils and surfactants via melt mixing or hot emulsification |
| Plastics Industry | Heat stabilizer and lubricant for polyvinyl chloride (PVC) | Used as an internal lubricant during PVC processing—such as extrusion, calendering, and injection molding—to reduce melt viscosity and improve flow behavior and mold release |
| Coatings & Inks | Flow leveling agent, matting agent component, wax additive | Dispersed or ground into solvent-based or water-based systems to regulate surface tension and gloss of coatings |
| Textile Printing & Dyeing | Softening agent and water-repellent finishing aid | Applied to fabric surfaces via pad-dry-cure process to impart hydrophobicity and improved hand feel |
| Food Packaging Materials | Processing aid for food-contact plastics (e.g., PE, PP) | Added to resins as a non-migrating lubricant during thermoforming processes such as blow molding and cast film extrusion; compliant with FDA 21 CFR 178.3620 |
| Pesticide Formulations | Cosolvent and stabilizer for emulsifiable concentrates (EC) and suspension emulsions (SE) | Homogenized with active ingredients and solvents to enhance storage stability and leaf surface spreading of the formulation |
Manufacturing Quality Control of METHYL STEARATE
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color and condition of the sample under natural light or standard light source to determine if it is a white to slightly yellow waxy solid or flake, and check for any impurities. |
| Melting Point | Capillary Melting Point Determination | Load the sample into a capillary tube and heat it at a constant rate. Record the temperature range at which the sample completely melts to assess its purity. |
| Acid Value | Acid-Base Titration | Dissolve the sample in ethanol, use phenolphthalein as an indicator, and titrate with a standard potassium hydroxide ethanol solution to determine the free acid content, calculating the acid value (mg KOH/g). |
| Ester Content (Purity) | Gas Chromatography (GC) | Use a polar capillary column and a flame ionization detector (FID). Quantitatively determine the content of methyl stearate by comparing retention time and peak area with standards. |
| Saponification Value | Reflux Saponification-Titration Method | React the sample with excess potassium hydroxide ethanol solution under reflux, then back-titrate the remaining alkali with a standard acid solution to calculate the amount of KOH required for saponification (mg KOH/g). |
| Moisture | Karl Fischer Method | Determine moisture content using the principle that iodine and sulfur dioxide react with water in the presence of pyridine and methanol, employing potentiometric or coulometric methods for precise measurement. |
| Color | Platinum-Cobalt Colorimetric Method | Dissolve the sample and compare it with the platinum-cobalt standard color scale to determine the color grade and evaluate the degree of purification. |
| Unsaponifiable Matter | Ether Extraction-Gravimetric Method | Extract unsaponifiable components with ether after saponification, evaporate the solvent, and weigh the residue to calculate the percentage of unsaponifiable matter. |
| Heavy Metals | Atomic Absorption Spectrometry (AAS) or Colorimetric Method | Dissolve the sample and measure the content of heavy metals such as lead, arsenic, and mercury using atomic absorption spectrometry to ensure compliance with safety standards. |
| Peroxide Value | Iodometric Method | In acidic conditions, peroxides in the sample react with potassium iodide to release iodine, which is then titrated with a standard sodium thiosulfate solution to calculate the peroxide value (meq/kg). |
