Directory Guidance on Polyquaternium-2 (CAS 68555-36-2)
Basic Chemical Info
Our commercial-grade Polyquaternium-2 (CAS 68555-36-2) is synthesized as a highly concentrated, water-soluble viscous liquid. Unlike low-tier formulations that display a deep amber tint and sharp amine off-odors, our proprietary refinement pipeline maintains a clear, straw-colored to near-water-white aesthetic with absolute batch-to-batch structural predictability.

FAQ
- Q1: What causes some commercial Polyquaternium-2 batches to turn dark amber, and how does your factory solve this?
A: Darkening is caused by the oxidation of unreacted secondary amines and trace iron contamination from low-grade carbon steel pipework during synthesis. Our entire production matrix uses SUS316L stainless steel and glass-lined chemical reactors, and every lot is stripped of volatile free amines, ensuring a pale-yellow to water-white color index throughout its entire shelf life. - Q2: Can Polyquaternium-2 be mixed directly with anionic surfactants or polymers?
A: As a highly charged cationic polymer, mixing Polyquaternium-2 directly with high concentrations of anionic surfactants will trigger an aggressive charge neutralization reaction, resulting in a cloudy precipitate or complex coacervate formation. It must be formulated with non-ionic, amphoteric, or compatible cationic matrices unless a precipitation/flocculation mechanism is specifically desired. - Q3: What is the direct factory Minimum Order Quantity (MOQ) for export?
A: Our standard sea-freight export MOQ is 1 full pallet (containing 4 heavy-duty drums, approx. 1,000 kg net weight) or 1 standard IBC tote. For global manufacturing enterprises conducting initial scale-up validation trials or pilot-scale synthesis runs, custom validation allocations can be authorized through our trade division.
Introduction to Polyquaternium-2 (CAS No. 68555-36-2)
Polyquaternium-2 (CAS No. 68555-36-2), globally recognized in the industrial chemical sector as Polyquat WT (or Mirapol WT), stands as a vital cationic polymeric surfactant. Featuring a dense, repeating quaternary ammonium structure along its hydro-backbone, it delivers exceptional structural stability, strong surface charge neutralization, and unparalleled shear resistance in highly saline environments.
Sourcing Polyquaternium-2 from a tier-2 broker or an uncertified chemical blender introduces significant operational liabilities, such as high residual monomers and erratic viscosity. You need a direct primary synthesis plant that controls step-growth polymerization kinetics, cross-linking limits, and chloride balances from the reaction vessel to your loading dock. This comprehensive B2B technical guide breaks down our manufacturing benchmarks, structural stability advantages, and global supply security infrastructure.
Advanced Production Technology
The primary technical defect in cheap Polyquaternium-2 batches is unmanaged polymerization termination, leaving excessive amounts of unreacted bis(2-chloroethyl) ether or free secondary amines. High residual chloro-endgroups cause the liquid to slowly cross-link inside the drum, creating localized gelling during transit. Our chemical plant eliminates this variance through an automated, closed-loop processing setup:
- Precision Condensation Loop: We react stoichiometrically balanced amounts of N,N‘-bis[3-(dimethylamino)propyl]urea with bis(2-chloroethyl) ether. The synthesis operates inside specialized SUS316L loop reactors under automated, computer-regulated heat curves to manage exothermic step-growth kinetics.
- Advanced End-Capping & Degassing: Once the target molecular weight distribution is achieved, our process injects a proprietary, non-hazardous terminating agent to deactivate residual chloro-endgroups, completely preventing autocatalytic post-polymerization during shipping.
- Multi-Stage Ion-Exchange and Decolorization: The concentrated polymer fluid passes through continuous carbon-bed loops and micro-filtration systems to strip away low-molecular-weight color complexes and heavy volatile residues, yielding a clean chromatogram baseline.

| Critical Operational Metric | Standard Tier-2 Trading Brokers | Our Primary Synthesis Plant | Impact on Downstream Formulations |
|---|---|---|---|
| Residual Free Monomer Count | Often >1.5 % , resulting in strong chemical odors and high toxic footprints. | Strictly managed ≤0.1 % via optimized stoichiometric charge. | Ensures complete operator safety and smooth compliance with strict global environmental audits. |
| Viscosity & Gelation Stability | Shifts significantly during transit; prone to thickening or layer separation. | Completely locked and stable viscosity via premium polymer end-capping. | Guarantees predictable pumping rates and zero nozzle clogging in automated dosing systems. |
| Electroplating Cloud Point | Distorted cloud points that cause unexpected haze in cyan-free zinc plating baths. | Perfectly consistent cloud point matrix via uniform molecular control. | Delivers flawless, high-brilliance leveling and ultra-even zinc/copper deposition layers. |
| Chloride Salt Balance | High fluctuating byproduct salts that reduce flocculation efficiency in water loops. | Strictly regulated ionic distribution via automated multi-stage washing. | Increases surface charge neutralization speed, reducing flocculation times by 20%. |
