| Industry | Application | Process |
|---|---|---|
| Plastics Industry | Internal lubricant and release agent for thermoplastic resins such as polyvinyl chloride (PVC) | Added to the formulation during plastic melt processing (e.g., extrusion, injection molding) to reduce intermolecular friction, improve melt flowability, and enhance surface finish of finished parts |
| Coatings & Inks | Flow leveling agent and matting agent for solvent-based coatings and printing inks | Incorporated during grinding or let-down stages to regulate surface tension, control film gloss, and prevent defects such as orange peel and cratering |
| Cosmetics | Lubricant and thickener in color cosmetics including foundations and eyeshadows | Micro-pulverized and dry-blended with other powder ingredients to improve product spreadability, slip, and adhesion |
| Rubber Industry | Release agent and activator in natural and synthetic rubber processing | Applied by spraying or incorporated into the compound prior to mixing or calendering to minimize adhesion of rubber to rolls or molds, thereby improving production efficiency |
| Metalworking | Extreme pressure (EP) additive in metal cutting fluids and rust preventive oils | Formulated with base oils and other functional additives to provide boundary lubrication via adsorbed film formation, reducing tool wear |
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe whether the sample is a white to light yellow waxy solid, free from visible impurities, lumps, or discoloration. |
| Melting Point | Capillary Method / Melting Point Apparatus | Determine the melting temperature range of the sample using a melting point apparatus or capillary method. The typical range is 75–82°C, in accordance with pharmacopoeia or enterprise standards. |
| Acid Value (AV) | GB/T 5530-2005 or ISO 3657 | Titrate free fatty acids in the sample with ethanolic potassium hydroxide solution. Calculate the milligrams of KOH consumed per gram of sample. Typically required to be ≤ 1.0 mg KOH/g. |
| Saponification Value (SV) | GB/T 5534-2008 or ISO 3656 | Saponify the sample with excess potassium hydroxide under reflux, then back-titrate with hydrochloric acid. Calculate the mg of KOH required to saponify 1g of sample. Typical value is 180–200 mg KOH/g. |
| Iodine Value (IV) | Wijs Method (GB/T 5532-2008) | Use the addition reaction of iodine with unsaturated bonds to determine the unsaturated fatty acid content. Pentaerythritol stearate should be a saturated ester, with an iodine value typically ≤ 1.0 g I₂/100g. |
| Moisture Content | Karl Fischer Titration (GB/T 6283) | Determine trace moisture in the sample by quantitative reaction with Karl Fischer reagent. Generally required to be ≤ 0.1%. |
| Ash Content | GB/T 5583-2007 (High-Temperature Ashing) | Ignite the sample at high temperature (550–600°C) until constant weight and measure the residual inorganic content. Typically required to be ≤ 0.05%. |
| Ester Content (Purity) | Gas Chromatography (GC) | Esterify the sample and inject into GC to separate and quantify stearic acid and pentaerythritol ester components. Calculate the main component content, typically required to be ≥ 98%. |
| Heavy Metal Content | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Digest the sample according to Chinese Pharmacopoeia or USP methods and measure the content of heavy metals such as lead, cadmium, mercury, and arsenic. Should meet pharmaceutical grade limits (e.g., Pb ≤ 2 mg/kg). |
| Thermal Stability (Weight Loss) | Thermogravimetric Analysis (TGA) | Programmed heating under nitrogen or air atmosphere to measure mass loss between 150–250°C, to evaluate thermal decomposition stability. |
| Solubility | Visual Observation Method | Test the solubility behavior of the sample in solvents such as ethanol, ether, and hot toluene. Should be easily soluble in hot organic solvents and insoluble in water. |
| Migration (for Food Contact Materials) | Simulant Extraction + GC/MS or HPLC | Contact the sample with food simulants (e.g., ethanol, hexane), then detect the amount of esters or monomers migrated using GC/MS or HPLC. Must comply with FDA/EC 10/2011 and other regulatory requirements. |
