Typical emulsifying agents include surface-Energetic agents, hydrophilic colloids, and finely divided solids. The HLB system helps in deciding on emulsifying agents primarily based on their own hydrophilic-lipophilic balance. Pharmaceutical purposes of emulsions include things likeThe kind of emulsion fashioned relies on the hydrophilic-lipophilic
