There seem to be a million sources on the internet to explain how to calculate the HLB of a (nonionic) surfactant in order to match it to the "HLB" (or more correctly the "required HLB) of the oil that is going to be emulsified. normitsWebThe HLB scale ranges from 0 to 20, with 10 corresponding to an emulsifier that is equally attracted to water and oil. Emulsifiers with HLB values greater than 10 are more hydrophilic and thus better at stabilizing o/w emulsions. In contrast, emulsifiers with HLB values less than 10 are more hydrophobic and therefore better suited for w/o emulsions. how to remove wallpaper sizing from wallWebmixtures) the HLB value determined by our method approximates better the HLB value calculated by chemical structure. • The particle size of surfactant association of the components not depends on the HLB value, but depends on the structure of surfactants.
