- Berol® 9969 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
- 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
