Hydrophilic Lipophilic Balance
An HLB with 0 can be considered for totally Lipophilic/Hydrophilic molecule while value 20 considered for completely Hydrophilic/lipophilic molecule.
The HLB value can be used to check the properties of surfactants of a molecule. This HLB value Scale of 0 to 20 is considered. You can determine ionic and non ionic surfactants.
- Value < 10 is lipid soluble (Water insoluble)
- Value > 10 is water soluble (Lipid insoluble)
- Value between 4 and 8 indicates anti-foaming agent
- Value from 7 to 11 indicates (water in oil W/O) emulsifier.
- Value from 12 to 16 indicates (Oil in water O/W) emulsifier.
- Value from 11 to 14 indicates wetting agents.
- Value from 12 to 15 indicates detergent.
- Value for 16 to 20 indicates hydrotrope or solubiliser.
