In turn, cross-linking alters the hydrophile-lipophile balance
of the biopolymer and its physicochemical properties.

In addition, Hydrophile-Lipophile Balance
(HLB) and length chain of surfactants may also affect the particle size of vesicles.

was maintained at 7.0.
W-O-W and O-W-O emulsions require two or more surfactants to be present in the system, one of which has a low Hydrophile-Lipophile Balance
(HLB) value to stabilise the primary WO emulsion and the other with a high HLB value to stabilise the secondary OW emulsion.

Commonly, these stabilizing surfactants are high HLB (hydrophile-lipophile balance
) ethoxylate or ionic types that are prone to stabilize foam as well.
A convenient approach to classifying emulsifiers is to consider their hydrophile-lipophile balance
