HLB

The hydrophilic-lipophilic balance number (HLB number) measures the degree of a molecule being hydrophilic or lipophilic. This number is calculated based on identifying various hydrophil and liphophil regions in the molecule. This number is a commonly used descriptor in any workflow in which lipid based delivery can be an option. (e.g. lipid-based drug delivery, cosmetics) The HLB Predictor is a general tool for predicting the HLB number. It can predict the HLB number based on the Davies or the Griffin method.
