Pyrethrins (CAS 121-29-9) are a natural insecticidal complex extracted from Chrysanthemum cinerariifolium flowers, consisting of pyrethrin I and pyrethrin II. We supply a concentrated technical-grade product as a viscous brown to amber liquid, standardized to ≥50% total pyrethrins (by GC). Each batch is accompanied by COA, MSDS, and TDS, ensuring traceability and consistency for formulation.
Our pyrethrins are manufactured under controlled conditions to preserve the natural ratio of the six active esters, which is critical for optimal knockdown and flushing activity. The product is free from synthetic synergists unless requested, making it adaptable for both conventional and organic-compliant formulations.
Synonyms: Pyrethrum extract, pyrethrum oleoresin, pyrethrin I & II, chrysanthemum cinerariaefolium extract, 121-29-9
Each batch is tested for assay (GC ≥50%), specific gravity, refractive index, and heavy metals (≤10 ppm). Full COA, MSDS, and TDS are provided on request. Stability data under recommended storage conditions is available for stability qualification.
Standard packaging includes 1 kg, 5 kg, and 25 kg containers, with custom and bulk options available. In-stock items ship within 3–5 working days; MOQ is 1 kg. For pricing, samples, and bulk orders, contact our sales team.
