Industrial Applications of POLYGLYCERYL-3 DIOLEATE
| Industry | Application | Process |
|---|---|---|
| Cosmetics | Emulsifier, stabilizer | Acts as an oil–water interfacial stabilizer in emulsions and creams; enables formation of stable emulsions by homogenizing or mixing oil and water phases under high-shear conditions |
| Cosmetics | Emollient | Matches the structure of skin lipids; improves product spreadability and moisturization through skin-feel modulation, commonly used in facial creams and body lotions |
| Food | Emulsifier | Used in margarine, salad dressings, and ice cream; facilitates uniform dispersion of oil into the aqueous phase via high-temperature emulsification |
| Personal care | Solubilizer for cleansers | Enhances solubilization of oily soils in shower gels and shampoos; works synergistically with surfactants to improve cleaning efficiency |
| Industrial | Lubricant additive | Added to metalworking fluids and cutting oils; improves lubricity and rust inhibition through enhanced miscibility with the oil phase |
| Pesticides | Emulsifying adjuvant for pesticides | Functions as an emulsifying adjuvant in pesticide formulations; enhances dispersion stability of oil-soluble active ingredients in water for spray application |
Manufacturing Quality Control of POLYGLYCERYL-3 DIOLEATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Acid Value | Acid-Base Titration | Neutralization of free fatty acids with standardized KOH solution using phenolphthalein indicator. |
| Saponification Value | Acid-Base Titration | Hydrolysis with excess KOH followed by back-titration to determine total ester content. |
| Hydroxyl Value | Acetylation Titration | Acetylation of hydroxyl groups with acetic anhydride, followed by titration of unreacted anhydride. |
| Iodine Value | Wijs Method | Addition of iodine monochloride to double bonds, followed by titration of unreacted halogen with sodium thiosulfate. |
| Water Content | Karl Fischer Titration | Electrochemical determination of water via iodine-sulfur dioxide reaction in pyridine-methanol medium. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Comparison of sample color against APHA platinum-cobalt standard solutions at 455 nm. |
| Refractive Index | Refractometry | Measurement of light bending angle through sample at specified temperature (e.g., 25 C) using calibrated refractometer. |
| Specific Gravity | Pycnometry or Digital Density Meter | Ratio of sample density to water density at defined temperatures, measured by buoyancy or oscillating U-tube principle. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal ions after acid digestion and atomization in flame or graphite furnace. |
| Residual Solvents | Gas Chromatography (GC) | Separation and quantification of volatile organic solvents using capillary column and FID detection. |
| Assay (Purity) | High-Performance Liquid Chromatography (HPLC) | Separation on reversed-phase column with UV detection at 205 nm, using external calibration. |
| Microbial Limits | Membrane Filtration and Plate Count | Enumeration of aerobic mesophilic microorganisms following filtration, membrane transfer, and incubation on agar media. |
