Neem oil nanoemulsions: characterisation and antioxidant activity
The aim of the present work is to develop nanoemulsions (NEs), nanosized emulsions, manufactured for
improving the delivery of active pharmaceutical ingredients. In particular, nanoemulsions composed of
Neem seed oil, contain rich bioactive components, and Tween 20 as nonionic surfactant were prepared.
A mean droplet size ranging from 10 to 100nm was obtained by modulating the oil/surfactant ratio.
Physicochemical characterisation was carried out evaluating size, f-potential, microviscosity, polarity and
