| Industry | Application | Process |
|---|---|---|
| Cosmetics | Humectant, emollient | Used as an oil substitute in emulsions, creams, and other skincare products; incorporated into the aqueous phase via emulsification to form a stable system |
| Food Industry | Plasticizer, emulsifier | Used in food packaging materials; blended with polymers (e.g., PVC) via thermal calendering or extrusion to enhance flexibility |
| Pharmaceuticals | Pharmaceutical excipient | Used as a plasticizer for soft capsule shells; mixed with gelatin and other components via melt blending prior to molding |
| Polymers | Polymer plasticizer | Added during processing of plastics such as PVC and EVA via melt compounding or solution coating to improve processability and elasticity |
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Assay (Active Component) | Gas Chromatography (GC) | After derivatization (e.g., acetylation), the fatty acid components in sorbitan esters (such as lauric acid, oleic acid) are measured by GC; quantification is based on peak area. |
| Free Fatty Acids | Acid-Base Titration / High-Performance Liquid Chromatography (HPLC) | Titration with standard alkaline solution to determine free acids, or HPLC separation and detection of unesterified fatty acids to assess degree of esterification and purity. |
| Residual Glycerol and Sorbitol | High-Performance Liquid Chromatography (HPLC) | Separation of unreacted sorbitol and glycerol using an amino or HILIC column, with detection and quantification by refractive index or evaporative light scattering detector. |
| Ethylene Oxide Residue | Gas Chromatography (GC) | Headspace sampling is used to detect residual ethylene oxide (EO) and its byproduct 2-chloroethanol (CE) in polysorbates, ensuring compliance with pharmacopoeial limits. |
| Peroxide Value | Iodometric Method / Titration | Determines the degree of oxidation of unsaturated fatty acid esters to evaluate product stability, especially suitable for esters containing unsaturated fatty acids. |
| Saponification Value | Titration Method (Pharmacopoeial Method) | The sample is refluxed with excess KOH for saponification, and the remaining base is back-titrated with acid. The result is expressed as milligrams of KOH consumed per gram of sample, reflecting the average molecular weight. |
| Acid Value | Acid-Base Titration | Determination of free acids in the sample using sodium hydroxide titration to assess acidic impurities from hydrolysis or oxidation, indicating product freshness. |
| Moisture Content | Karl Fischer Method | Precise measurement of trace moisture to ensure product stability and prevent microbial growth or hydrolysis reactions. |
| UV Absorbance (Color and Impurities) | UV-Visible Spectrophotometry (UV-Vis) | Measurement of absorbance at wavelengths between 270–300 nm to evaluate the presence of aromatic impurities or oxidative degradation products (e.g., peroxide breakdown compounds). |
| Microbial Limits | Pharmacopoeial Microbial Count Method | Detection of total aerobic microbial count, molds and yeasts, and specified control organisms (e.g., Escherichia coli), ensuring sterility or low bioburden, applicable for pharmaceutical excipients. |
