1. HLB calculator
With this tool, you can calculate the HLB of a combination of two surfactants.
Input parameters: the HLB of the two surfactants and the required HLB;
Output parameter: the ratio in which you need to mix the two surfactants.

2. HLB-NAC calculator
For those of you that heard me speak about the "Hydrophilic-Lipophilic Difference – Net Average Curvature (HLD-NAC)" theory, which provides the basis for a more efficient use of surfactants in the context of microemulsions (higher solubilization at lower surfactant levels), please be aware that the software associated with the HLD-NAC theory can now be freely downloaded [1] from the website of Prof. Steven Abbott. This is the computer package I also showed during my presentations.
