HLB应该有统一算法的。

How do we determine the HLB "value" of a surfactant?

We calculate the water loving portion of the surfactant on a molecular weight
basis and then divide that number by 5.

this keeps the HLB scale smaller and more manageable. The working scale is from
0.5 to 19.5.

this number is then assigned to the nonionic surfactant.

For example:
Brij 98 (oleth-20) is a 20 mole ethoxylate of oleyl alcohol.
We calculate the molecular weight of the 20 moles of ethylene oxide:
20*44=880
We add this number to molecular weight of the oleyl alcohol.
880+270=1150 (the mol. wt of Brij 98)
What percentage of 1150 is 880?
880/1150=76.5%
76.5% divided by 5 = 15.3

15.3 is the HLB value of Brij 98.
