Understanding the process variables that occur during emulsion manufacturing can assist formulators in preventing production inconsistencies as well as selecting the most effective surfactant blend for a given purpose. This in turn reduces the amount of surfactant required without affecting emulsion quality or stability, thus saving resources and even improving product quality, as the present article describes.

Polymer use began in the 1800s with cellulose derivatives, the vulcanization of rubber, and styrene synthesis; but in reality, it started more than four million years ago with the formation of DNA and proteins. Polymers are a diverse class of chemistry. By definition, they are large molecules made up of chains or rings of linked monomer units—simple reactive building blocks. Smaller molecules or monomers are combined to form polymers that possess a characteristic chain structure of multiple repeating units that can be related or different.

The present study examines formulations prepared using similar oil fractions and differing emulsifier systems and process parameters to determine why their behaviors differ. Results showed that ethoxylated emulsifier systems were the most stable, and that beyond a certain number of cycles, high pressure homogenization did not significantly improve the quality of the product.
