PESTICIDE FORMULATION: Suspension Concentrates (SC) & Our Surfactant Solutions

Suspension Concentrates (SC) are a stable, water-based dispersion system widely used in crop protection formulations. Solid active ingredients, insoluble in water, are finely milled via wet grinding in the presence of wetting agents, dispersing agents, and other additives—creating a formulation that forms a stable suspension upon dilution. This water-based system offers significant advantages in safety and environmental profile.

Key Advantages:

Eco-friendly, water-based
Enhanced safety in processing, storage, and transportation
Easy to apply in the field

A.I. Requirements:

Solid melting point > 60°C
Stable and non-degradable in water
Low water solubility < 500 mg/L

Key Specifications:

Suspensibility
pH
Particle size
Viscosity
Storage stability

Main Components: a.i. + wetting & dispersing agents + antifreeze + defoamer + thickener + biocide + water

Dispersants & Wetting Agents: Powering Stable & Effective SC

Surfactants are the critical component that determines SC performance. They provide optimal wetting and dispersion during wet-milling, preventing particle aggregation for long-term physical stability.

Our Surfactant Portfolio:

Universal SC Surfactants: Pro-SC1K, Pro-SC1KL
Dispersants: Tristyrylphenol Ethoxylates Phosphate/Sulfate Esters, Block Copolymer, Polycarboxylate & Sulfonate Dispersants
Thickeners: Xanthan Gum, Magnesium Aluminum Silicate

Expert Solutions for Formulation Challenges:

Preventing Ostwald Ripening – Effectively inhibiting particle size growth with co-dispersants like Pro-DP23
Enhancing Suspension Rates – Ensuring superior uniformity
Managing Solubility – Stabilizing active ingredients with higher water solubility using Pro-DP17
