(hydrophilic– philippic balance). The increase E/S ratio and E/S content enhance the reduction of the kinematic viscosity. A mixture design was applied to optimize the composition of each component to predict the desired kinematic viscosity. Compared with the other models, the results indicate that the full cubic model of a {3,3} simplex lattice model with three interior points and a centroid in the mixture design (providing) displayed the best fit when screening and optimizing the kinematic viscosity with R2 = 0.998 and MAPE = 5.031%.
