Abstract Conditions to produce highly concentrated emulsions or gel emulsions were investigated in water/sucrose dodecanoate/oil systems. HLB (Hydrophile-Lipophile Balance) of sucrose dodecanoate is changed by increasing the number of dodecane carboxylic groups attached to the sucrose ring. In order to know the correlation between the phase behavior and the formation of highly concentrated emulsions, the phase diagram of the water/mixed sucrose dodecanoate/decane system was constructed. In the sucrose monododecanoate system, the surfactant is mainly dissolved in water and forms micelles. With the increase in lipophilic chains, the sucrose surfactant tends to form reverse micelles in oil via microemulsions and lamellar liquid crystal. The formation of O/W-type and W/O-type highly concentrated emulsions is related to this phase behavior. The formation of W/O-type emulsions is enhanced upon addition of monolaurin.
