Detailed explanation-1: -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.

Detailed explanation-2: -The HLB system, which stands for “Hydrophilic Lipophilic Balance”, indicates how the proportion of those groups will affect surfactant behavior in emulsions. HLB numbers correspond to the degree of water or oil solubility of a particular surfactant. Lower HLB numbers indicate better oil (non-polar) solubility.

Detailed explanation-3: -HLB= E / 5 can be calculated with this equation. E: Percentage by weight of ethyleneoxide • HLB value of fatty acid esters of polyhydric alcohols such as glyceryl monostearate, HLB= 20 [1-(S / A)] is calculated with that equation. The HLB values of some of the most frequently used surfactants are shown in Table 11.1.
