Agrochemical emulsion-type concentrates and diluted concentrate formulations. In particular oil-in-water emulsion concentrates having an oil phase with oil soluble active, continuous water phase with an optional water soluble active, and a combination of a optionally acyl terminated alkoxylated polyol or polyamine surfactant emulsifier and a high HLB co-surfactant. Use of said surfactant emulsifier for oil-in-water agrochemical emulsion concentrates is found to provide for stable emulsion concentrates over time and under varying storage temperatures.
