Basic Information
Scope
Main technical contents: **Project**: **Indicator**: - Chrysanthemum extract quality fraction a/%: - 1.3~1.7 - pH value: - 4.0~7.0 - Pourability/residue after pouring (%): - ≤3.0 - Residue after washing (%): - ≤0.5 - Emulsion stability (diluted 200 times): - No oil floats, sediment, or precipitation in the graduated cylinder. - Persistent foaming (foam volume after 1 minute): - ≤25 mL - Low-temperature stability: - After cold storage, the volume of sediment at the bottom of the centrifuge tube does not exceed 0.3 mL. - Heat storage stability: - After heat storage, the chrysanthemum extract quality fraction remains no less than 95% of the measured value before storage, and the pH value and emulsion stability still meet the requirements of this document. **Note**: Chrysanthemum extract is a mixture of six insecticidal components, including chrysanthemum extract I, glycoside I, moth-killing extract I, chrysanthemum extract II, glycoside II, and moth-killing extract II.
