Specification: Pyrethrins are typically available as a pale yellow to amber oily liquid or powder, extracted from Chrysanthemum cinerariifolium flowers, standardized to contain 25-50% total pyrethrins (pyrethrin I and II, cinerin I and II, jasmolin I and II) for agricultural or household use.

Appearance and Color: pale yellow to amber liquid or powder

Ingredient Information: Pyrethrins are a mixture of six natural esters (pyrethrin I, pyrethrin II, cinerin I, cinerin II, jasmolin I, jasmolin II) derived from pyrethrum flowers, often formulated with synergists like piperonyl butoxide and stabilized with solvents or carriers like diatomaceous earth.

Uses: Pyrethrins are widely used as insecticides to control pests like mosquitoes, flies, and agricultural insects, valued for their rapid knockdown effect and low mammalian toxicity; they are also applied in household sprays, pet shampoos, and organic farming due to their natural origin and biodegradability.
