Hlb value means

WebFeb 25, 2024 · Higher HLB surfactants (>10) are hydrophilic (“water loving”) and form O/W (Oil-in-water) emulsions. Lipophilic surfactants possess low HLB values (1-10) and form W/O (water-in-oil) emulsions. Dish detergents, surfactants for emulsion polymerization, and the following example (SLS = Sodium Lauryl Sulfate) are high HLB surfactants. WebThe HLB number is defined as the ratio of hydrophile group to lipophile group, which essentially indicates whether a surfactant will promote water-in-oil or oil-in-water emulsion. Biosurfactants with HLB values less than 6 are lipophilic and favors stabilization of water-in-oil emulsification.
