- Agrochemicals Features
- 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.
- Product Highlights
- 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® 9927 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.
- 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
