SE additives
Suspo-Emulsion (SE)
Suspo-emulsion (SE) formulations typically contain combination of active ingredients in one formulation with a total content between 10.0 - 70.0 wt.%. In this formulation, one active ingredient is suspended as water-insoluble solid particles, while another active ingredient is incorporated as emulsified oil droplets. The combination of suspension and emulsion properties provides improved stability, preventing settling of solid particles over time.
The formulation is intended for dilution with water before application (spray mixture).
Key-factors:
- Combination of active ingredients with different physical properties are possible.
- No crystal formation under cold storage conditions.
- Easy to handle.
- Enhancing biological efficacy.
