Formation of water-in-oil (W/O) nano-emulsions in a water/mixed non-ionic surfactant/oil systems prepared by a low-energy emulsification method

Selective Laser Sintered Poly(L-Lactide)/Carbonated Hydroxyapatite Nanocomposite Scaffolds: A Bottom-up Approach

“…Some nanoemulsions appear milky with droplet sizes up to 500 nm. Nanoemulsions, in contrast to microemulsions, are not thermodynamically stable but highly kinetically stable because of their small droplet sizes which make them stable against sedimentation and creaming (Uson, Garcia et al 2004). One major disadvantage of microemulsions is that they require large amounts of surfactants and co-surfactants (typically over 20 wt%) to prepare.…”

The influence of glicerides oil phase on O/W nanoemulsion formation by pic method

“…In contrast to microemulsions, nanoemulsions are characterized by kinetic stability [1][2][3][4][5][6]. As a form of cosmetics products they can relatively easily penetrate into the skin, exhibit a high degree of hydration and soften the skin and have a very good user properties (ease of spreading on the skin, no greasy feeling).…”

Formulation and in vitro Evaluation of Ketoprofen in Palm Oil Esters Nanoemulsion for Topical Delivery

“…The defined size of nanoemulsion are varies in literature. However a well accepted typical droplets size falls in the range of 20 -500 nm 10) . The results obtain by laser scattering spectroscopy are in the range of nanoemulsion.…”

“…Nanoemulsion is chosen as the transdermal dosage form because it is a promising novel dosage form in terms of controlling droplet size, relatively long-term stability and powerful solubilization ability 9) . Nanoemulsion is defined as emulsion with the droplet size of 20-500 nm 10) . Due to their characteristic size, nanoemulsion appears transparent or translucent to the naked eyes and possesses stability against sedimentation or creaming.…”
