Viscosity modifiers (Xanthan gum, Magnesium Aluminosilicate [Veegum])
Viscosity modifiers such as xanthan gum and magnesium aluminosilicate (Veegum) are widely used in agrochemistry to regulate the rheological properties of liquid formulations (CS (Microcapsulated Suspensions)), including pesticides, herbicides and fertilizers. They ensure the stability of suspensions, prevent delamination and improve the adhesion of preparations to plant surfaces.
Xanthan gum
Xanthan gum (E415) is a natural polysaccharide obtained by fermentation using the bacteria Xanthomonas campestris. It is highly soluble in water and highly resistant to changes in pH (from 2 to 12) and temperature (from -18 °C to +120 °C), which makes it an effective thickener and stabilizer in various agrochemical preparations. Xanthan gum is compatible with other thickeners such as guar gum and carob gum, showing a synergistic effect and increasing the viscosity of solutions.
Magnesium Aluminosilicate (Veegum)
Magnesium aluminosilicate, known by the trade name Veegum, is an inorganic clay mineral used as a thickener, stabilizer, and suspending agent. It is effective at low concentrations and ensures the stability of suspensions by preventing precipitation of solid particles. Veegum also improves the rheological properties of the formulations, ensuring easy application and uniform coating.
Application in agrochemistry
• Stabilization of suspensions: Prevention of separation and precipitation of solid particles in liquid preparations.
• Viscosity control: Ensuring optimal consistency for ease of use and improved plant coverage.
• Compatibility with other components: Effective combination with various active substances and adjuvants to enhance the effectiveness of drugs.
Main features
Xanthan Gum:
• High resistance to a wide range of pH and temperatures.
• Compatible with other thickeners and stabilizers.
• The ability to form pseudoplastic solutions that facilitate application.
Veegum:
• Effectiveness at low concentrations.
• Ability to prevent precipitation and delamination.
• Improved texture and stability of shapes.
What to look for when choosing
• Compatibility with active ingredients: Make sure that the selected viscosity modifier does not interact negatively with the active ingredients of the drug.
• Conditions of use: Evaluate the pH and temperature range at which the product will be used to select the appropriate thickener.
• Desired consistency: Determine the required viscosity and rheological properties to ensure ease of use and effectiveness.
Cost-effectiveness: Consider the dosages and cost of modifiers to optimize costs in the production of agrochemicals.
