Key Benefits
  • Robust – can be used with many active ingredients and solvents
  • Tolerant to temperature and quality variations
  • Convenient – easy to use and dose
  • Effective at low concentrations
  • Better hard water tolerance
  • Reduced complexity and stock keeping
  • Berol® 9960 is a nonionic / anionic emulsifier blends for standard aromatic solvent based EC formulations
  •  The basic pair consists of Berol 9960 and Berol 9968.
  • Depending on the HLB of the EC the emulsifier ratio needs to be determined by means of a ratio check. Berol 9927 and Berol 9969 can be used in more hydrophobic formulations.
Matched Pair of Emulsifier Blends
  • The blend of emulsifiers includes anionic and nonionic surfactants in a balanced composition that brings ideal electrostatic and steric stabilization to the emulsion. In combination, as a matched pair, these four blends work for most pesticides and common solvents.
Stabilization of Emulsions

Repulsive forces must be dominant for stable systems. Two mechanisms affecting dispersion stability:

  • Electrostatic or charge stabilization - This is the effect on emulsified droplet interaction due to the distribution of charged species in the system

           Berol 9960 - Stabilization of Emulsions

  • Steric repulsion - This involves polymers adsorbing onto the surface and preventing the droplets coming into close contact. The thickness of the coating is sufficient to avoid van der Waals forces and flocculation
