Project Description

Agrochemical Defoamer | Foam Control for Pesticide Formulations

Excess foam is a frequent challenge in pesticide manufacturing and agricultural applications. Foaming in agrochemical formulations often causes persistent foam, which leads to production slowdowns, packaging issues, and reduced product efficacy. INVINO provides a complete range of agrochemical defoamer solutions tailored to common formulation types—SC, SL, SE, EW, EC, OD, ME, WDG, WP, DF—ensuring stability, long-lasting performance, and optimal compatibility.

Key Performance Criteria of Our Agrochemical Defoamers

  • Shear & Salt Endurance: Maintains persistent foam suppression under high-shear sand milling (for SC/SE) and high-electrolyte herbicide environments (for SL).
  • Zero Phytotoxicity Risk: Highly modified chemistries prevent phase separation and oil slicks, eliminating the risk of crop burn during foliar application.
  • Formulation Integrity: Exceptional compatibility with active ingredients, wetters, and dispersants without negatively impacting droplet spreading or leaf penetration.
  • Regulatory Compliance: Inert ingredients optimized for minimal environmental impact, supporting your global registration processes.

Defoamer Selection Guide by Formulation Type

Prevent oil slicks, phase separation, and potential phytotoxicity. Select the precise anti-foaming agent engineered for your specific pesticide or herbicide formulation:

Formulation Type Process Challenges Chemistry & Performance Recommended Model
SL (Soluble Liquid)
Herbicides (e.g., Glyphosate, Glufosinate) 		High electrolyte/salt concentration. Extreme risk of oil spotting and phase separation. Polyether-Modified Siloxane Exceptional compatibility in high-surfactant systems. Zero oil slick to prevent crop burn. INVINO-2200 Download TDS ⬇
SC / SE / EW
Suspension & Emulsion Concentrates 		Severe foaming during high-shear milling (sand mills). Long-term storage instability. Shear-Stable Modified Emulsion Resists emulsion breakdown under extreme mechanical shear. Ensures uniform particle size distribution. INVINO-6225 Download TDS ⬇
WDG / WP / DF
Water-Dispersible Granules & Powders 		Foaming upon field dilution (tank-mix). Poor wetting speed due to entrapped air. Silicone on Inert Carrier Dry-blending friendly. Accelerates wetting and ensures stable anti-foam performance upon reconstitution. INVINO-2502 Download TDS ⬇
Processing & Packaging
General Factory Operations 		Air entrainment during fluid transfer, recirculation, and high-speed filling lines. Fast-Knockdown Emulsion Rapid defoaming action at low dosages. Prevents bottle overflow and ensures accurate filling volumes. INVINO-370 Download TDS ⬇

Technical FAQ: Defoaming Agrochemicals & Herbicides

Q: Will the defoamer cause phytotoxicity (crop burn) or clog spray nozzles?
Standard dimethyl silicone fluids often coalesce in agricultural formulations, causing localized oil spotting on leaves that leads to severe phytotoxicity. Our specialty modified chemistries (such as polyether-modified siloxanes) are engineered for complete dispersion. They prevent phase separation, ensuring zero oil slick, and will not clog fine drone nozzles or delicate spray equipment.
Q: Is it stable in high-surfactant herbicides like Glyphosate SL?
Yes. Herbicides like Glyphosate and Glufosinate contain extreme electrolyte and surfactant concentrations that rapidly break down conventional emulsions. We utilize highly compatible, shear-stable agents (e.g., INVINO-2200) that maintain long-term transparency and persistent foam knockdown in these demanding Soluble Liquid (SL) environments without precipitating.
Q: What is the difference between In-Can and Tank-Mix defoamers?
In-Can defoamers (like INVINO-6225) are formulated into the pesticide during manufacturing to withstand high-shear sand milling and ensure multi-year shelf stability. Tank-Mix antifoams (like INVINO-2502) are agricultural adjuvants added directly by the end-user into the spray tank to rapidly destroy foam generated during field dilution and prevent pump cavitation.
