| Cosmetics / Personal Care | pH adjuster (stabilizes the pH of the product system) | Added during manufacturing to adjust the final product’s pH |
| Pharmaceuticals | Topical drug base or excipient (used in ointments and creams to enhance drug hydration) | Blended with active pharmaceutical ingredients to prepare topical formulations |
| Food | Nutritional fortificant (used in sports drinks or functional foods to supplement amino acid metabolites) | Dissolved or blended into food raw materials per food additive specifications |
Manufacturing Quality Control of Sodium L-pyroglutamate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 200-210 nm, comparing peak area against a certified reference standard. |
| Water Content | Karl Fischer Titration | Electrochemical titration with iodine-based reagent to determine water content based on stoichiometric reaction with water. |
| Residue on Ignition | Gravimetric Analysis | Heating sample at 700-800 C to constant weight and measuring inorganic residue as percentage of original mass. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion, using plasma emission spectroscopy calibrated with lead standards. |
| Chloride | Ion Chromatography | Separation and quantification of chloride anions using anion-exchange column and conductivity detection. |
| Sulfate | Barium Sulfate Gravimetry | Precipitation of sulfate as BaSO4 under controlled pH and temperature, followed by filtration and weighing. |
| pH (1% aqueous solution) | Potentiometric Measurement | Measurement of hydrogen ion activity using calibrated glass electrode in a 1% w/v aqueous solution at 25 C. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a standardized solution in a sodium D-line field. |
| Related Substances | HPLC-UV | Separation and quantification of structurally related impurities (e.g., pyrrolidone, proline derivatives) using gradient HPLC. |
| Microbial Contamination | Membrane Filtration | Filtration of sample solution, followed by incubation on appropriate agar media and colony enumeration. |
| Loss on Drying | Thermogravimetric Analysis | Mass loss measured after drying at 105 C for 2 hours under atmospheric pressure. |
| Iron (Fe) | AAS | Atomic absorption spectroscopy following acid digestion and matrix-matched calibration for iron quantification. |
