HLB Scale: Hydrophilic-Lipophilic Balance

HLB Scale

Developed by Griffin (1949), the HLB Scale ranks the tendency of a surfactant to be hydrophilic or hydrophobic (lipophilic). Since a surfactant molecule has both hydrophilic and hydrophobic portions (that's why its a surfactant!) Griffin developed a ranking system to determine 'how hydrophilic' and 'how hydrophobic' a surfactant is. To summarize:

  • A
  • B
  • C
