Hydrophilic Lipophilic Balance Tech Video

When formulating emulsions, selecting the right nonionic surfactant for the job can be challenging due to varying oil characteristics, demanding formulation stability requirements, and a wide variety of potential surfactants. To aid surfactant selection, hydrophilic-lipophilic balance, or HLB, is a simple descriptor of a surfactant’s relative hydrophobicity, and is one way to classify emulsifiers and solubilizers. High HLB surfactants are generally water-soluble. Low HLB surfactants are usually oil soluble. Using this system, a formulator matches the HLB of a surfactant to the HLB requirements of the application. Simple rules-of-thumb are widely recognized. For oil emulsification or solubilization in water, the composition of the oil will dictate the required surfactant HLB. For oil mixtures, approximate HLB requirements can be conveniently calculated from those of the individual oil components. Similarly, the HLB of surfactant mixtures can be readily estimated from those of the individual surfactants, a strategy known as HLB Bridging. Bridging not only enables fine tuning of HLB, but surfactant mixtures often display superior performance over single components. For your convenience, surfactant HLBs can be found in the Stepan Alkoxylate Product Guide, located within the Stepan website, as well as in product bulletins. HLB-based surfactant selection is another example of a potential challenge faced by formulators. Turn to Stepan as your partner in solving formulation challenges.
