Development of eco-friendly emulsions produced by microfluidization technique

Green solvents have recently attracted much attention due to the necessity of replacing traditional solvents. In this work, a mixture of eco-friendly solvents and a green surfactant have been utilized in emulsions with a potential use for agrochemicals. Results obtained show that the Microfluidizer® was capable of producing very fine nanoemulsions (D3,2=280nm).This contribution has demonstrated the significant role of the rheology to understand the destabilization processes which occur in emulsions with very similar DSD. Thus, we found the optimum homogenization pressure was 1034bar (15,000psi) on account of the lack of creaming and of low coalescence.
