Calculate the Total HLB of a mixture of components

Enter the % proportion of the component and its HLB value
(leave remaining rows as 0)

 % of Component HLB value Component 1 (HLB value {0-20}) Component 2 (HLB value {0-20}) Component 3 (HLB value {0-20}) Component 4 (HLB value {0-20}) Component 5 (HLB value {0-20}) HLB of Mixture (HLB)

Calculate the amounts of surfactants required for a Target HLB
 HLB of Surfactant A (HLB value {0-20}) HLB of Surfactant B (HLB value {0-20}) Target HLB (HLB value {0-20}) Amount of A required (%) Amount of B required (%)

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.
