| Textiles | Antistatic agent | Dissolved in water and applied to textiles via padding or spraying |
| Textiles | Softener | Blended into softener formulations to enhance textile hand feel and appearance |
| Water treatment | Biocide | Dissolved in water and uniformly distributed throughout the water system using dosing equipment |
| Water treatment | Flocculant | Dissolved in water and used to remove suspended solids via flocculation |
Manufacturing Quality Control of Polyquaternium-2
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Active Content (as polyquaternium-2) | Acid-Base Titration | Quantifies quaternary ammonium groups via back-titration with standardized acid after reaction with excess anionic surfactant. |
| pH | Potentiometric Measurement | Measures hydrogen ion activity in aqueous solution using calibrated pH electrode and reference electrode. |
| Viscosity | Rotational Viscometry | Determines resistance to flow under shear stress using a rotating spindle in controlled temperature conditions. |
| Appearance | Visual Inspection | Assesses physical state, clarity, and presence of visible particulates or phase separation against standard light source. |
| Color (APHA) | Spectrophotometric Comparison | Compares sample absorbance at 430 nm to platinum-cobalt standard solutions for yellowness index. |
| Moisture Content | Karl Fischer Titration | Quantifies water content via stoichiometric iodine reaction with sample in anhydrous methanol-based reagent. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and cooling to constant weight. |
| Heavy Metals (as Pb) | ICP-OES | Detects trace metal elements by measuring characteristic atomic emission intensities after plasma atomization and excitation. |
| Chloride Ion Content | Potentiometric Titration | Determines Cl- concentration using silver nitrate titrant and silver/silver chloride indicator electrode. |
| Molecular Weight Distribution | Size Exclusion Chromatography (SEC) | Separates polymer chains by hydrodynamic volume in solution and compares elution times to calibrated standards. |
| Microbial Contamination | Membrane Filtration | Quantifies viable aerobic microorganisms by filtering sample, culturing on agar, and counting colony-forming units. |
| Surfactant Impurities | HPLC-UV | Separates and quantifies residual monomers or surfactant by-products using reversed-phase column and UV detection. |
