WebThe HLB of the emulsifier affected its ability to displace interfacial proteins and the interfacial PC of different HLB emulsions, as shown in Fig. 5. In general, the interfacial … WebThe HLB scale ranges from 0 to 20, with 10 corresponding to an emulsifier that is equally attracted to water and oil. Emulsifiers with HLB values greater than 10 are more hydrophilic and thus better at stabilizing o/w emulsions. In contrast, emulsifiers with HLB values less than 10 are more hydrophobic and therefore better suited for w/o emulsions.
