Ecotoxicology of Glycerol Monolaurate nanocapsules

•Development of Nanocapsule with Glycerol Monolaurate.•Acceptable values of physico-chemical parameters after 120 days.•Protector effect of nanostructuration against Folsomia candida.•Decrease on fish mortality with GML Nanocapsules.

Glycerol Monolaurate (GML) is a compound with known antimicrobial potential, however it is not much used due to its low solubility in water and high melting point. The nanoencapsulation of some drugs offers several advantages such as improved stability and solubility in water. The present study aimed to produce, characterize, and evaluate the ecotoxicity of GML nanocapsules. The nanocapsules were produced and presented a mean diameter of 210 nm, polydispersity index of 0.044, and zeta potential of −23.4 mV. The electron microscopy images showed the nanometric size and spherical shape. The assay in soil showed that GML has a high toxicity while the GML nanocapsules showed decreased toxic effects. Nanostructuration also protected the Rhamdia quelen against the toxic effects of GML. Concluding, the formulation shows positive results and is useful to predict the success of development besides not damaging the soil.
