Preparation of non-toxic nano-emulsions based on a classical and promising Brazilian plant species through a low-energy concept

Abstract:

A true sustainable and ecofriendly concept of utilization of natural products must involve not only the obtainment of plant material in consonance with biodiversity preservation, but also the potential lower risk to the environment and lower consume of energy in the transformation of the plant into novel products. We therefore describe an elegant study in which the fruits of Pterodon emarginatus, a high promising Brazilian species that can be obtained through a sustainable use of biodiversity, are the natural raw material for the preparation of nano-emulsions. The essential oil was prepared by hydrodistillation, using a classical extraction with a non-toxic solvent instead of organic solvents. Moreover, the utilization of low energy emulsification method at room temperature and rational design with blends of non-ionic surfactants allowed the preparation of nano-emulsions with desirable properties. An optimal nano …
