Industrial Applications of N,N-BIS(CARBOXYMETHYL)-L-GLUTAMIC ACID TETRASODIUM SALT
| Industry | Application | Process |
|---|---|---|
| Detergents | Acts as a chelating agent to soften hard water and enhance cleaning performance | Formulated with other surfactants for liquid or powder detergent production |
| Personal Care | Used as a stabilizer and chelating agent in shampoos and body washes | Mixed with primary surfactants after pH adjustment to prevent product degradation caused by metal ions |
| Agriculture | Acts as a chelating agent for micronutrients to improve fertilizer efficiency | Chelated with metal ions such as iron and zinc prior to incorporation into liquid fertilizers |
| Water Treatment | Used in boiler water treatment to inhibit calcium and magnesium scale formation | Applied as a scale inhibitor in combination with other water treatment chemicals |
| Food Industry | Used as a food additive (subject to regional regulatory approval) to stabilize color and texture | Binds metal ions during processing to prevent oxidative discoloration |
| Textile Printing & Dyeing | Acts as a metal ion sequestrant in bleaching and dyeing processes | Added to processing baths to bind heavy metal ions, improving dyeing uniformity |
| Papermaking | Used as a hydrogen peroxide bleach stabilizer to prevent metal-catalyzed decomposition | Added during the pulp bleaching stage to form stable complexes with transition metal ions |
Manufacturing Quality Control of N,N-BIS(CARBOXYMETHYL)-L-GLUTAMIC ACID TETRASODIUM SALT
| Detection Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe sample color and physical state (typically colorless to pale yellow transparent liquid or white crystalline powder) to determine compliance with specifications. |
| pH Value | pH Meter Determination | Prepare an aqueous solution of a specified concentration (e.g., 10% w/v), then measure the pH using a calibrated pH meter. The value is generally within the range of 7.0–9.0. |
| Content (Main Component Purity) | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column, with phosphate buffer-methanol as the mobile phase, and UV detection (~210 nm) for quantitative analysis of GLDA content. |
| Chelating Capacity (Chelation Value) | Metal Ion Titration (e.g., Ca²⁺/Cu²⁺ Titration) | Titrate the sample with standard metal ion solutions under specific pH conditions, using o-cresolphthalein complexone or PAN as indicator, to determine chelating equivalents. |
| Moisture Content | Karl Fischer Titration | Use either volumetric or coulometric Karl Fischer reagent to titrate water content in the sample; suitable for solid or high-concentration liquid samples. |
| Residue on Ignition (Sulfate Ash) | Gravimetric Method (High-Temperature Ignition) | Ignite the sample in a muffle furnace at 600–800°C until constant weight. The residue is weighed to calculate ash content, assessing the level of inorganic impurities. |
| Heavy Metal Content | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, determine residual levels of lead, arsenic, cadmium, mercury, etc., using AAS or inductively coupled plasma mass spectrometry (ICP-MS). |
| Chloride Content | Silver Nitrate Titration (Mohr’s Method) | In nitric acid medium, titrate chloride ions with standardized silver nitrate solution, using potassium chromate as indicator; the endpoint appears as a brick-red precipitate. |
| Free Amine or Organic Impurities | Thin Layer Chromatography (TLC) or GC-MS | TLC for preliminary screening of impurity spots; GC-MS for qualitative and quantitative analysis of volatile organic impurities (may require derivatization). |
| Density (for Liquid Products) | Density Meter or Specific Gravity Bottle Method | Measure the density of liquid samples at 20°C using a digital density meter or specific gravity bottle to assess concentration consistency. |
| Stability (Thermal/Light Stability) | Accelerated Stability Testing + HPLC Monitoring | Store samples under elevated temperature (e.g., 60°C) or intense light for a set period, then periodically sample and analyze by HPLC to evaluate degradation of the main component. |
