[9] reported that in A0T/H20/toluene systems, the acrylamide acts as a
cosurfactant during the polymerization and is mostly located at the w/o interface rather than inside the micelles.
Nanoemulsions are thermodynamically stable, transparent nano-dispersions that are smaller than 100 nm in droplet size, stabilized by an interfacial film formed by surfactant and
cosurfactant molecules.
An aqueous emulsifier mix containing 3.4 ml Tween 80 (surfactant), 1.1 ml n-butanol (
cosurfactant), and 2.1 ml distilled water was stirred at a speed of 300 rpm and at a temperature of 70[degrees]C on a hot plate magnetic stirrer.
The major technique for enhancing bio-availability is SEDDS, which uses lipophilic, pre-concentrated solutions of the active pharmaceutical ingredient and excipients (a liquid carrier, a surfactant and a
cosurfactant).
These are stabilized by an interfacial film of surfactant and
cosurfactant molecule.
Alcohols could change the osmotic pressure of the latex particle surface as they work as
cosurfactant in miniemulsion.
