Formulation development is the art of making stable formulations that become instable when they need to deliver the active ingredient.
However, up to the application of the formulation, stability is crucial within the set specification. Physical stability of formulations is an important parameter during formulation development, especially when testing multiple phase systems (suspensions or emulsions). Physical stability can refer to any kind of attributes ranging from appearance to color to viscosity from agglomeration to phase transformations like dissolution, melting or crystallization.
This white paper is going through the essentials of physical stability of formulations, covering topics such as stability testing, observation of eutectic, crystal growth, agglomeration and how these topics are practically related to the physical stability of agrochemical formulations.
