Industrial Applications of METHYL 12-HYDROXYSTEARATE
| Industry | Application | Process |
|---|---|---|
| Cosmetics | Thickener, stabilizer, emulsifier | Used in formulations of emulsions, creams, and other skincare products to enhance rheological properties and stability |
| Plastics & Rubber | Plasticizer, lubricant | Acts as an internal plasticizer in plastics processing to improve flexibility; serves as a processing aid in rubber compounding |
| Lubricants | Extreme pressure additive, anti-wear agent | Added to lubricating oils to enhance anti-wear performance and boundary lubrication under high-temperature, high-pressure conditions |
| Inks | Rheology modifier, anti-settling agent | Improves thixotropy and storage stability of inks, preventing pigment settling |
| Coatings | Anti-settling agent, flow control agent | Applied in powder or liquid coatings to control viscosity and improve film leveling |
Manufacturing Quality Control of METHYL 12-HYDROXYSTEARATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Acid Value | Acid-Base Titration with KOH in ethanol | Neutralization of free carboxylic acid groups with standardized potassium hydroxide solution, using phenolphthalein indicator. |
| Hydroxyl Value | Acetylation followed by back-titration with NaOH | Esterification of hydroxyl groups with acetic anhydride, then titration of unreacted anhydride after hydrolysis. |
| Iodine Value | Wijs Method (titration with iodine monochloride) | Addition of excess iodine monochloride to double bonds, followed by titration of unreacted halogen with sodium thiosulfate. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemical generation and titration of iodine to quantify water based on stoichiometric reaction with Karl Fischer reagent. |
| Color (Gardner Scale) | Visual Comparison or Spectrophotometric Measurement | Comparison of sample color against standardized Gardner liquid color standards under controlled lighting conditions. |
| Refractive Index | Refractometry at 20 degrees C | Measurement of light bending angle as it passes through the liquid sample at specified temperature using a calibrated refractometer. |
| Saponification Value | Alkaline Hydrolysis followed by Acid-Base Titration | Complete ester hydrolysis with excess KOH, then back-titration of unreacted alkali with standardized HCl. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal impurities after acid digestion and matrix-matched calibration using hollow cathode lamp absorption. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Heating sample to 700-800 degrees C to volatilize organic matter, then weighing inorganic residue remaining. |
| Unsaponifiable Matter | Solvent Extraction and Gravimetry | Extraction of non-saponifiable components with diethyl ether after alkaline hydrolysis, followed by solvent evaporation and weighing. |
| Appearance (Clarity and State) | Visual Inspection | Assessment of physical state (solid/liquid), clarity, and presence of particulates or phase separation under ambient conditions. |
