| Sumario: | The target of this investigation was to compare the yield of three different eco-friendly surfactants derived from cocoa oil for the development of oil-in-water emulsions formulated with a mixture of green solvents as dispersed phase, N,N-dimethyldecanamide y a-pinene. Rheology, laser diffraction, optical microscopy and multiple light scattering were the main techniques used to assess the emulsification properties of the surfactants. Slightly concentrated ecological emulsions were obtained using all the studied surfactants, which differ in the number of ethoxylated groups. Nevertheless, it has been demonstrated that the use of the non-ionic surfactant with higher number of ethoxylated groups (Levenol C201) is adequate for three reasons: (a) allowing the lowest droplet size to be achieved, (b) providing the sufficient viscosity to prevent creaming and (c) no destabilization by coalescence occurs. The systematic characterization presented in this work provides important new findings on emulsifying properties of polyoxytheylene glycerol ester surfactants derived from coconut oil, which can be applied in the rational development of new biocompatible products. |
