Industrial Applications of Polyhexamethyleneguanidine hydrochloride
| Industry | Application | Process |
|---|---|---|
| Water Treatment | Biocide for algae and microbial control in recirculating cooling water systems | Dosed into the cooling water system at 5–20 mg/L; effective over 24–48 hours at pH 6.0–9.0 |
| Textile Dyeing and Printing | Antimicrobial finishing agent for fabrics | Applied via padding (two dips, two nips; pickup rate 70–80%), dried at 100–110°C, then cured at 150°C for 1–2 minutes |
| Personal Care Products | Preservative in hand sanitizers, wet wipes, and other personal care formulations | Directly blended with formulation components at ambient temperature; final concentration 0.01–0.1% (w/w) |
| Agriculture | Seed treatment fungicide | Applied via seed coating or soaking; soak seeds in a 0.1–0.5 g/L solution for 15–30 minutes, then air-dry before sowing |
| Medical Devices | Low-temperature disinfectant for endoscopes, catheters, and similar devices | 2% aqueous solution; 10-minute contact time at 20°C, compliant with GB/T 27949-2022 “Technical Requirements for Disinfectants Used on Medical Devices” |
| Papermaking | Microbiocide for pulp and white water systems | Continuously dosed online into the white water recirculation system at 2–10 mg/L; effective at pH 5.5–8.5 |
Manufacturing Quality Control of Polyhexamethyleneguanidine hydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (PHMG-HCl content) | Acid-base titration with NaOH | Quantifies guanidine groups by back-titration after reaction with excess standardized acid. |
| pH (1% aqueous solution) | Potentiometric pH measurement | Measures hydrogen ion activity using calibrated glass electrode in diluted sample solution. |
| Heavy metals (as Pb) | Atomic absorption spectroscopy (AAS) | Determines total heavy metal content by atomization and absorption of characteristic UV-Vis radiation. |
| Chloride ion (Cl-) | Argentometric titration (Mohr method) | Titrates Cl- with AgNO3 using K2CrO4 indicator; endpoint signaled by red Ag2CrO4 precipitate. |
| Water content | Karl Fischer coulometric titration | Electrochemically generates iodine to react with water; quantifies water based on charge consumed. |
| Residue on ignition | Gravimetric analysis (weight loss on heating) | Measures non-volatile inorganic impurities by weight difference before and after high-temperature ashing. |
| Iron (Fe) | Inductively coupled plasma optical emission spectrometry (ICP-OES) | Atomizes and excites sample; measures Fe-specific emission wavelength intensity. |
| Sulfate (SO42-) | Barium sulfate gravimetric method | Precipitates SO42- as BaSO4, filters, dries, and weighs the insoluble residue. |
| Appearance (solution clarity) | Visual inspection against standard solutions | Compares sample clarity and color to reference standards under controlled lighting and viewing conditions. |
| Specific gravity | Digital densitometry | Measures mass per unit volume at specified temperature using oscillating U-tube principle. |
| Microbial contamination | Membrane filtration and colony counting | Filters sample through sterile membrane, incubates on agar, and enumerates viable colonies. |
| Related substances (impurity profile) | Reversed-phase HPLC with UV detection | Separates PHMG-HCl and structurally related impurities using C18 column and UV absorbance detection. |
