“…It leads to the spontaneous formation of oil droplets surrounded by aqueous phase through a budding process 16,22 . Nanoemulsions can also be prepared by dilution of microemulsions or cubic liquid crystals with water 14,35 . During dilution with water, the co-surfactants diffuse from the oil-water interface to an aqueous phase.…”

“…Recently, nanomaterials (particle size \100 nm) are being developed and offer the opportunity to more efficiently and safely administration of pesticides, fungicides, herbicides, and fertilizers by better delivery of active ingredients, and less environmental drift Gogoi et al 2009). Antimicrobial nanoemulsions are highly stable oil-inwater emulsions composed of nanometer-sized, positively charged droplets that have broad-spectrum activity against enveloped viruses, fungi, and bacteria (Hamouda et al 2001;Myc et al 2002;Wang et al 2007). Nanobiocide a product prepared by mixing several bio-based chemicals was reported to eliminate fungus Magnaporthe grisea, the causal agent of rice blast disease (Gogoi et al 2009).…”

The current research deals with the formulation and characterization of bio-based oil-in-water nanoemulsion. The formulated eugenol oil nanoemulsion was characterized by dynamic light scattering, stability test, transmission electron microscopy and thin layer chromatography. The nanoemulsion droplets were found to have a Z-average diameter of 80 nm and TEM study reveals the spherical shape of eugenol oil nanoemulsion (EON). The size of the nanoemulsion was found to be physically stable up to more than 1-month when it was kept at room temperature (25°C). The TEM micrograph showed that the EON was spherical in shape and moderately mono or di-dispersed and was in the range of 50-110 nm. Three concentrations of the nanoformulation were used to evalute the anti-fusarium activity both in vitro and in vivo experiments. SDS-PAGE results of total protein from the Fusarium oxysporum f. sp. vasinfectum (FOV) isolate before and after treatment with eugenol oil nanoemulsion indicate that the content of extra cellular soluble small molecular proteins decreased significantly in EON-treated fungus. Light micrographs of mycelia and spores treated with EON showed the disruption of the fungal structures. The analysis of variance (ANOVA) for Fusarium wilt incidence indicated highly significant (p = 0.000) effects of concentration, genotype, and their interaction. The difference in wilt incidence between concentrations and control was not the same for each genotype, that is, the genotypes responded differently to concentrations. Effects of three EON concentration on germination percentage, and radicle length, were determined in the laboratory. One very interesting finding in the current study is that cotton genotypes was the most important factors in determining wilt incidence as it accounted for 93.18 % of the explained (model) variation. In vitro experiments were conducted to evaluate the potential phytotoxic effect of three EON concentrations. Concentration, genotype and concentration x genotype interaction were all highly significant sources of variation in seed germination; however, interaction was the first in importance as a source of variation followed by the concentration, while genotype was the least important source of variation. These results suggest the potential use of eugenol oil nanoemulsion for protecting seedcotton from Fusarium wilt infection.

IIn this study, O/W type nano-emulsions were prepared by phospholipid-nonionic surfactant mixtures and octyldodecylmyristate using the phase transition low-energy emulsification method. The nano-emulsions were formed only in the very narrow area of the concentration of mixed surfactant and oil molar ratio of around 1 : 1. The particle size of the emulsions was decreased as adding the aqueous phase into the emulsions after phase inversion point unlike the emulsions formed only with nonionic surfactant. Nano-emulsion was stable at room temperature for more than a month. Thus, the nano-emulsions containing phospholipids can be widely used as a cosmetic formulations.
