HLB, Hydrophilic-Lipophilic Balance

 Many years ago I learned about HLB numbers, which estimated properties of
 surfactants.  My recollection is that these are calculated numbers, but I
 haven't been able to find anything which tells me HOW to calculate them.
 If you know the secret, could you please pass it along?  I will, of course,
