SE Surfactants

Suspoemulsion (SE) formulations serve as a means to merge two active ingredients possessing vastly different physical characteristics into a single formulation. They represent a fusion of suspension concentrate (SC) and concentrated aqueous emulsion (EW) technologies. The key benefits lie in the ability to formulate multiple active ingredients concurrently, expanding the range of effectiveness and eliminating the drawbacks associated with tank-mix incompatibility.

Formulating SEs can be challenging. To prevent issues like flocculation, crystal growth, and coalescence, it's advisable to employ polymeric surfactants. Enhancing anchoring and colloidal stabilization is essential to meet performance criteria. We suggest initially developing stable EW and SC formulations separately. Once stability is achieved individually, combining them is recommended. To minimize instability in the final SE formulation, using the same surfactant system whenever possible is advised.

• • Combines diverse active ingredients with varying solubilities or melting points
• • Utilizes a mix of active ingredients for wider pest control coverage
• • Eliminates the need for tank mixing, preventing potential spray tank
     incompatibilities

• • The surfactant system must accommodate both an insoluble organic solid and a liquid
• • Partial solubility of active ingredients in water or oil phases can lead to stability issues
• • Typically high-loaded, which may result in long-term stability concerns if appropriate
