Griffin's method for non-ionic surfactants as described in 1954 works as follows: where is the molecular mass of the hydrophilic portion of the molecule, and M is the molecular mass of the whole molecule, giving a result on a scale of 0 to 20. An HLB value of 0 corresponds to a completely lipophilic/hydrophobic molecule, and a value of 20 corresponds to a completely hydrophilic/lipophobic molecule. WebThe HLB number is usually on a scale of 0–20. Lower HLB values are an indication of high oil affinity. A high HLB value, on the other hand, indicates high water-solubility.
