HLB Value

One or more emulsifying agents (emulsifiers) can be used to emulsify immiscible liquids. It is important to determine the balance of the lipophilic and hydrophilic structures of the components that make up the system, in the selection of the emulsifier to be used. The determination of the HLB value which expresses this balance helps to find the appropriate emulsifying agent and to form the emulsion necessary for the stabilization of the system. It is important to know the HLB value of the system and the emulsifier, and to choose the emulsifiers that contain the appropriate chemical groups for the system. It is possible to form o/w (oil-in-water) or w/o (water-in-oil) emulsions at different temperatures and oil concentrations with a single emulsifier.
