Development of Emulsifiable Concentrate Formulations Using Experimental Design Software

Source

This paper examines two experimentation processes for developing an emulsifier system for an EC herbicide formulation. The first process is the traditional method of single factor experimentation, and the second process uses DOE (Design of Experiments) computer software. A four component emulsifier system is optimized using both processes. The advantages and disadvantages of both processes are discussed.

The use of DOE techniques for mixtures gives the researcher a greater level of understanding of the interactions of the variables in the experimental system, compared to single factor experimentation. The software used in this study did create predictive models for the formulation developed, thus allowing the selection of the optimum blend of the components after evaluation of seventeen blends. The property selected for evaluation was emulsion separation as a function of water hardness.
