WebIn fact, an emulsifier with HLB=10 shows a balance, at room temperature, of the hydrophilic and lipophilic properties. This is proven by the fact that for W/O/S systems with homologous surfactant, those with an HLB number greater than 10 produce O/W emulsions, while those with HLB lower than 10 tend towards W/O emulsions. The hydrophilic–lipophilic balance (HLB) of a surfactant is a measure of its degree of hydrophilicity or lipophilicity, determined by calculating percentages of molecular weights for the hydrophilic and lipohilic portions of the surfactant molecule, as described by Griffin in 1949 and 1954. Other methods have been suggested, notably in 1957 by Davies.
