Abstract: Structured agrochemical concentrates comprise agrochemical actives dispersed in a structured oil system of an oil and structurant oligomer including urethane and/or urea linkages and residues of a dimer or trimer component. The concentrate formulations may contain other components such as surfactants without the structurant loosing its effect a problem with known structurants. The concentrates can be readily diluted to give sprayable agrochemical formulations.
