FAQ
A: PMD is widely recognized as the only plant-derived active ingredient with repellent protection times comparable to synthetic DEET. Unlike DEET, PMD does not melt plastics or synthetic fabrics, features a pleasant herbal mint aroma, and is generally preferred for sensitive skin and family-friendly formulations.
A: PMD should be stored in original, tightly sealed drums in a cool, dry, well-ventilated warehouse away from direct sunlight and heat sources (recommended storage temperature: 15°C to 25°C). Avoid prolonged exposure to air to prevent moisture absorption.
A: We supply PMD in 25 kg fiber drums lined with double PE bags, 50 kg plastic drums, or 200 kg steel drums for high-volume manufacturers. Each shipment includes a batch-specific Certificate of Analysis (COA), Safety Data Sheet (SDS), and technical support for custom formulation development.

Regulatory Compliance & Global Certifications
Navigating global biocide regulations requires rigid quality tracking. Shandong Zhishang Chemical provides comprehensive compliance support to streamline your brand’s regional registration:
ISO 9001:2015 Certification: Enforces strict quality management protocols across raw material selection, catalytic transformation, distillation, and nitrogen-sealed filling.
EPA & EU Biocidal Products Regulation (BPR) Data Support: Our PMD technical data aligns with guidelines established by major environmental protection frameworks for registered active substances.
REACH Compliance Documentation: Complete analytical dossiers available for European Union importers and downstream formulators.
Cruelty-Free & Sustainable Origin Verification: Processed without animal testing, utilizing renewable terpene feedstocks to satisfy consumer demand for clean-label insect repellents.
Because insect repulsion performance depends heavily on structural isomer distribution and low impurity thresholds, each export production lot of p-Menthane-3,8-diol undergoes four-step laboratory verification before Certificate of Analysis (COA) release:
GC-FID Isomer Quantification: Measures total purity (≥ 98.0%) and verifies the specific ratio of cis-PMD and trans-PMD to guarantee optimal vapor evaporation rates.
Residual Isopulegol & Citronellal Assay: Limits unreacted terpene precursors (Isopulegol < 0.5%, Citronellal < 0.2%) via gas chromatography to minimize potential skin sensitization risks.
Heavy Metal Trace Analysis (ICP-OES): Confirms Lead (< 5 ppm) and Arsenic (< 1 ppm) remain well below global cosmetic and personal safety limits.
Thermogravimetric Loss on Drying: Checks moisture and volatile organic solvent residues to maintain clear dissolution when diluted into alcohol-based or aqueous lotion systems.
