Resumo
We propose the development of hydrogel-thickned nanoemulsions (HTNs) with tea tree essential oil
(Melaleuca alternifolia) and vitamin A palmitate (retinyl palmitate). Nanoemulsions and HTNs were
produced by the use of phase inversion method, employing non-ionic surfactants. As surfactant phase
were used sorbitan esters and hydrogenated/ethoxylated castor oil. HTNs with drops size ranging
between 86 to 96 nm were obtained, depending on the polymer used, with increased viscosity.
Rheological profile of developed HTNs was determined, showing the influence of the kind of polymer
used, here all presented pseudo-plastic behaviour, with different viscosity measurement.
