Direct factory procurement from JIMPOCHEM—delivering analytical perfection, regulatory assurance, and global logistics reliability.
An authoritative examination of molecular architecture, antimicrobial mechanisms, and industrial purity standards for global B2B procurement engineered by JIMPOCHEM.
Zinc Pyrithione (CAS 13463-41-7; IUPAC: Bis(1-hydroxy-1H-pyridine-2-thionato-O,S)zinc) features a coordination complex of zinc with two pyrithione ligands. Formula: C10H8N2O2S2Zn (MW: 317.70 g/mol). Its planar coordination lattice endows it with extraordinarily low aqueous solubility, making it ideal for persistent rinse-off and weather-resistant surface coatings.
ZPT exerts potent antifungal and antibacterial action via membrane depolarization and copper-ion transport inhibition. By disrupting cellular transport mechanisms through membrane proton-motive force neutralization, it targets fungi such as Malassezia globosa, gram-positive/gram-negative bacteria, and marine fouling algae with microscopic precision.
JIMPOCHEM synthesizes two standard commercial physical forms tailored for downstream manufacturing: High-Purity Micronized Powder (≥ 98.0% active purity, D50 < 1.5 µm) and Stable 48% Fine Particle Suspension (FPS) aqueous dispersion stabilized with non-ionic dispersants for liquid surfactant formulations.
| Property / Parameter | ZPT Powder Grade (CAS 13463-41-7) | ZPT 48% Liquid Dispersion (FPS) |
|---|---|---|
| Appearance | White to Off-White Fine Powder | Off-White to Pale Yellow Aqueous Dispersion |
| Active Content (Assay) | ≥ 98.0% Min | 48.0% - 50.0% |
| Zinc Content (Zn) | 19.4% - 20.6% | 9.3% - 9.8% |
| Particle Size (D50) | 1.2 µm - 1.8 µm | 1.0 µm - 1.5 µm |
| pH (1% aqueous slurry / neat) | 6.5 - 8.5 | 6.5 - 9.0 |
| Heavy Metals (Pb / As) | Pb ≤ 10 ppm | As ≤ 2 ppm | Pb ≤ 5 ppm | As ≤ 1 ppm |
| Primary Industrial Applications | Anti-dandruff shampoos, paints, plastics, textiles | Liquid hair care, aqueous coatings, adhesives |
How regulatory dynamics, eco-compatibility demands, and advanced material engineering are shaping the procurement landscape for CAS 13463-41-7.
While European regulations have restricted ZPT in cosmetic rinse-offs within EU member states (Annex III update), demand across North America, Asia-Pacific, Latin America, and the Middle East remains robust. ZPT continues to be the gold standard anti-dandruff active due to its superior cost-to-performance ratio against Malassezia species compared to alternative actives like Climbazole or Piroctone Olamine.
JIMPOCHEM Solution: We supply ultra-low free-zinc ZPT dispersions with tight particle size distributions to prevent sediment compaction, ensuring optimal suspension stability in personal care formulations without phase separation.
With global bans on organotin catalysts (TBT) and tightening limits on heavy metals, the marine coatings industry relies heavily on Zinc Pyrithione as a booster biocide. ZPT effectively prevents soft fouling (seaweeds, slime, bio-films) on vessel hulls and submerged offshore structures.
JIMPOCHEM Solution: Our micro-encapsulated marine-grade ZPT powder offers controlled leaching rates, enhancing paint longevity, reducing fuel drag for commercial shipping vessels, and fulfilling environmental leaching criteria.
Modern architectural materials, automotive interiors, medical device housings, and PVC flooring require long-term protection against fungal degradation and bacterial odor development. ZPT exhibits high thermal stability (up to 200°C), making it suitable for compounding into polymers.
JIMPOCHEM Solution: We supply masterbatch-ready dry ZPT powders with surface-modified hydrophobic coatings for flawless dispersion into EVA, PVC, PE, and polyurethane resins.
Exterior architectural coatings exposed to tropical or humid climates face constant risk of mold, mildew, and black algae staining. Standard dry-film preservatives wash out rapidly under torrential rainfall.
JIMPOCHEM Solution: Synergistic blends of ZPT with IPBC or Octhilinone (OIT) engineered by JIMPOCHEM deliver broad-spectrum dry-film bio-protection with prolonged UV resistance and ultra-low water solubility leaching.
Established in 2010 in Jinan City Chemical Industry Park, Shandong Province, JIMPOCHEM spans over 500 acres. We integrate R&D, digital synthesis, global trade, and technical support.
Leveraging strategic raw material sourcing, our modern production base utilizes intelligent DCS automated control systems to balance massive scale synthesis with precise batch-to-batch consistency for CAS 13463-41-7.
Quality is the lifeline of JIMPOCHEM. Every lot undergoes HPLC assay analysis, heavy metal ICP-OES screening, particle size laser diffraction, and full batch digital traceability supporting 3rd-party lab validation (SGS/Eurofins).
Aligned with national dual-carbon goals, our manufacturing park employs advanced catalytic oxidation for waste gas treatment, membrane wastewater recycling, and full REACH compliance dossiers for overseas chemical import.
Ensuring continuous supply, chemical safety compliance, and next-generation product evolution for high-tier industrial partners.

Essential technical, regulatory, and commercial answers for chemical procurement managers sourcing CAS 13463-41-7 from China.
A: ZPT 98% micronized powder is the concentrated pure chemical form, ideal for masterbatch compounding in plastics, synthetic rubbers, dry powder formulations, and solvent-based marine antifouling coatings. The 48% aqueous dispersion (FPS) is a pre-dispersed liquid suspension containing specialized non-ionic stabilizing agents designed for seamless incorporation into liquid personal care products, water-borne latex paints, and industrial aqueous emulsions without requiring high-shear milling equipment.
A: Phase separation in ZPT suspensions occurs due to particle agglomeration and gravity settlement over prolonged storage. JIMPOCHEM utilizes proprietary micro-milling technology to restrict particle size distribution to D50 < 1.5 µm while employing a multi-component rheology control network (xantham/cellulose matrix paired with polymeric dispersants). This ensures long-term thixotropic stability, maintaining easy pourability and preventing irreversible hard caking even after 12 months of storage.
A: Every commercial batch dispatched from our Jinan plant includes a comprehensive batch-specific Certificate of Analysis (COA), 16-section Safety Data Sheet (SDS) compliant with GHS Revision 8, Technical Data Sheet (TDS), REACH registration statement, and UN 3077 Dangerous Goods Certificate for marine transportation. Third-party heavy metal and purity analysis reports (e.g., SGS) are provided upon request prior to loading.
A: Our standard MOQ for Zinc Pyrithione is 500 kg for 48% dispersion (drums) and 100 kg for 98% powder. Sample orders (1–5 kg) for R&D lab evaluation are dispatched within 48 hours via express air courier (DHL/FedEx). Commercial container orders are typically processed, packed, and loaded at Qingdao or Shanghai Port within 7 to 10 working days following L/C or T/T confirmation.
A: Yes. As a direct synthesis manufacturer with over 500 acres of chemical engineering capacity, we offer tailored particle size reduction (e.g., sub-micron D50 < 0.9 µm for optical coatings) as well as customized biocide synergistic mixtures combining ZPT with Octhilinone (OIT), IPBC, or Carbendazim tailored to your regional climate challenges and formulation matrix.
