Advanced Formulation for stable, effective agricultural products
Suspension concentrates (SC) are liquid products—fertilizers, pesticides, fungicides, and other agri-chemicals—where active ingredient solids are dispersed and suspended in water. Unlike other formulation types, a stable SC requires active ingredients that remain insoluble under all temperature conditions, making them fundamentally different from solutions where actives dissolve.
This difference matters. Because SCs maintain active ingredients as distinct particles, they're significantly more effective than emulsified concentrate (EC) or wettable powder (WP) formulations. The solid particles deliver superior performance in the field while offering end-users convenience and reliability.
Why Agricultural Companies Choose Suspension Concentrates:
- Safe to store and transport
- Work with most active ingredients that have low water solubility
- Easy to add enhancers for bio-enhancement and performance optimization
- Outperform both EC and WP formulations in the field
- Applicators appreciate the liquid convenience
Important Considerations
Suspension concentrates demand careful formulation. They require moderate agitation to keep solids suspended. Crystals can form if partially soluble ingredients exceed solubility limits. The suspended solids can cause internal equipment wear if not managed properly. And long-term stability can be challenging, especially upon dilution in the spray tank.
This is where formulation expertise becomes critical. The balancing act between suspending solids effectively while maintaining pumpability through your equipment and the end-customer's sprayer requires precision and experience.
How We Formulate Suspension Concentrates
Manufacturing stable suspension concentrates is a science. Our facility is specifically optimized for SC formulation, and every aspect of our process reflects that specialization.
We manage the critical balance between viscosity and flowability—keeping viscosity high enough that solids remain suspended, but low enough that your concentrate moves easily through equipment. We prevent air entrainment during manufacturing and shipping to avoid foaming and active ingredient de-mixing. And we carefully control mixing to prevent heterogeneous flocculation, which would destabilize the suspension.
Typical SC Components:
- Active ingredients (insoluble solids)
- Wetting agents
- Dispersants
- Viscosity modifiers (thickeners)
- Preservatives
- Water (the carrier liquid)
Getting this chemistry right—where each component works in harmony—is what separates a formulation that works from one that doesn't.
Understanding Other Liquid Concentrate Options
While suspension concentrates are highly effective, there are other liquid concentrate types worth understanding:
- Emulsified Concentrates (EC): Similar to SCs except active ingredients are suspended in an oil base with a surfactant emulsifier. Upon dilution, they form an oil-in-water emulsion. Generally less effective than SCs.
- Microemulsion Concentrates (MC/MEC): Essentially emulsified concentrates that form a microemulsion upon dilution. MCs have lower active ingredient concentrations and more surfactants than other types.
- Suspoemulsions (SE): Water-based like SCs but containing both suspended solids and emulsion droplets. More complex to design, requiring prevention of both solid settling and emulsion creaming.
- Soluble Liquids (SL): Contain dissolved active ingredients in water. Mix easily and require minimal agitation, but work only with water-soluble actives.
For most agricultural applications requiring solid active ingredients, suspension concentrates remain the gold standard for performance and reliability.
Understanding SC Manufacturing Costs
Pricing for suspension concentrate contract manufacturing depends on several key factors:
- Processing Complexity: Some products require more complicated processing. Our experts optimize formulations to balance quality and cost efficiency.
- Production Volume: We offer economies of scale for large batches and an affordable test facility for smaller pilot runs before bulk production.
- Quality Testing Requirements: Testing for stability and performance standards affects cost. We ensure products meet specifications without over-testing, balancing cost and integrity.
