Weblipophobic and lipophilic phase respectively forming a strong connection. Surfactants behaviour is dependent on the hydrophilic and lipophilic balance (HLB), so as to form W/O (water in oil) microemulsion surfactants with HLB value from 4-6 are preferred whereas surfactants with HLB from 8-18 are preferred for O/W (oil in water) microemulsion [6]. WebThus, at least two surfactants are required: One with low HLB (Hydrophilic Lipophilic Balance) forms the primary W/O emulsion and another surfactant with a high HLB achieves the secondary o/w emulsification. In this sense, polymeric emulsifiers provide a strong, thick, and well-defined film around the W/O interface .
