Industrial Applications of 1,3-Bis(2-hydroxyethyl)-5,5-dimethylhydantoin
| Industry | Application | Process |
|---|---|---|
| Personal Care | Preservative in cosmetics, inhibiting bacteria, fungi, and yeasts in emulsions, creams, shampoos, and similar products | Acts as a formaldehyde-releasing active ingredient; hydrolyzes slowly within the formulation pH range of 4–8 to release trace amounts of formaldehyde for antimicrobial action |
| Industrial Water Treatment | Microbiocide for cooling water systems, papermaking wet-end applications, and coating systems | Dosed into recirculating water systems or pulp slurries; maintains effective biocidal concentration through sustained formaldehyde release and is compatible with common water treatment auxiliaries |
| Coatings & Adhesives | In-can preservative for waterborne coatings and construction adhesives | Added during the final stage of production (paint adjustment); prevents microbial degradation during storage, thereby avoiding viscosity loss, gas formation, or spoilage |
| Textile Printing & Dyeing | Preservative component in textile finishing auxiliaries | Used in combination with other functional auxiliaries to prevent spoilage of printing pastes or finishing solutions during storage and application |
Manufacturing Quality Control of 1,3-Bis(2-hydroxyethyl)-5,5-dimethylhydantoin
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 210 nm, based on peak area comparison against a certified reference standard. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via iodine-sulfur dioxide reaction in a methanol-based solvent system. |
| Appearance | Visual Inspection | Assessment of physical state and color by observation against standard white background under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated capillary tube method per USP <741>. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and Cr after acid digestion, based on atomic emission intensity at element-specific wavelengths. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue remaining after high-temperature ashing at 500-600 C, expressed as percentage weight loss. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride anion using suppressed conductivity detection after eluent gradient separation. |
| Related Substances | HPLC-UV | Identification and quantification of structurally similar impurities using gradient HPLC with UV detection and relative retention time matching. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of hydrogen ion activity in a 1% w/v aqueous solution using calibrated glass electrode and pH meter. |
| Solvent Residues (e.g., Methanol, Acetone) | GC-FID | Quantitative analysis of residual solvents by gas chromatography with flame ionization detection using internal standard calibration. |
| Bulk Density | ASTM D1895 Method A | Measurement of mass per unit volume for freely settled powder using a standardized graduated cylinder and balance. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size distribution based on angular scattering pattern of laser light passing through dispersed sample in air or liquid medium. |
