Prediction of the surface tension of surfactant mixtures for detergent formulation using Design Expert software

The formulation of a detergent product is a complicated task which depends on many economical, ecological, and practical parameters. The goal is to achieve a product which will have optimal washing properties and significantly decreases the surface tension. Therefore the prediction of minimal surface tension of a mixture of four different surfactants can be very beneficial for the industry. In this work it was performed by using Design Expert State – Ease software. This program was successfully applied for the prediction of minimal surface tension and optimization of the composition of the different surfactants mixtures. Predicted data were compared to experimental results and a very good correlation was achieved. For further application more complex optimization procedures can be performed by adding additional parameters to the Design Expert software program. Therefore this program is extremely useful for the laundry industry and could be successfully applied in many other, more complex tasks.
