Application and positioning

A pyrethroid with a broad pest spectrum and strong contact activity, widely used in public health, turf and cotton programmes. The technical material is a waxy solid with very low water solubility; cis/trans ratio and crystal form affect suspension stability in SC and EW formulations. Laurand supplies it from audited Chinese producers in kilogram to tonne lots, with the batch documentation buyers need for registration and incoming QC.

Quality and documentation

  • Batch-specific Certificate of Analysis with active content by HPLC or GC and the relevant impurity profile
  • Water content, acidity and insoluble matter as applicable to the technical grade
  • Analytical methods aligned with CIPAC where a CIPAC method exists for the active ingredient
  • Five-batch trend data and a pre-shipment sample for laboratory confirmation
  • SDS in the language of your market, with GHS classification for the destination

Packaging and handling

  • 25 kg fibre drums or woven bags with inner PE liner; 200 L drums and IBCs for liquid grades
  • Sealed and dry; technical material is hygroscopic in some grades and is packed accordingly
  • Store in a dry, ventilated warehouse away from alkalis, acids and strong oxidising agents
