Definitions for "HLB"
Ratio between hydrophilicity and hydrophobicity of surfactants. HLB gives information about the behaviour of these surfactants in various processes.
A property of a surfactant which is represented by an arbitrary scale of 0-20 wherein the most hydrophilic materials have the highest numbers. The HLB of a nonionic surfactant is the approximate weight of ethylene oxide in the surfactant divided by 5.
