| HLB
- Hydrophilic-Lipophilic Balance Calculator for Emulsions |
|
Calculate the Total HLB of a mixture of
components
Enter the % proportion of the component and its HLB value
(leave remaining rows as 0)
Calculate the amounts of surfactants
required for a Target HLB
|
Calculation(s) used
where
C1,C2,C3.. = Component proportion, %
HLB1,HLB2,HLB3.. = HLB value for the component
where
HLBA = HLB of the 1st surfactant
HLBB = HLB of the 2nd surfactant
x = Target HLB
%A = Amount of Surfactant A required
%B = Amount of Surfactant B required (%B = 100 - %A)

Notes
The HLB scale devised by
Griffin in 1949 is a scale from 0 - 20 (20 being Hydrophilic) used to
characterise the nature of surfactants and balance their proportions in
order to stabilise disperse systems.
