[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.
Briefly, mixtures of cyclohexane (75 ml), Triton X-100 (17.7 ml), and n-hexanol (18 ml) as oil, surfactant, and cosurfactant phases, respectively, were mixed with 4.8 ml aliquots of Rubpy dye solution (20 mM in deionized water).
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).
To find out the suitable components for dexibuprofen microemulsion, the solubility of dexibuprofen in oil (ethyl oleate), surfactants (Tween 40,60, and 80 and triethanolamine), and cosurfactant (PG, PVA, PEG 400, and ethanol) was determined through method reported by Roni and Jalil [10].
Curcumin water solubility was also increased successfully using a microemulsion vehicle containing a surfactant, oil, and cosurfactant and this increase in water solubility translated in an about 22 times higher bioavailability of curcumin in rats [138].
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.
