Sodium lactate and heat transfer method question

[Klmeier]

I have been a hobbyist soap maker for over 15 years. I have recently started to use the heat transfer method. I would like to use sodium lactate to harden the bars. I know the general rule is to add it to the cooled lye water. However, I'm using the heat of the lye water to melt my harder fats/butters. When should I add the sodium lactate?

Add it with your soft oils.

Thank you.

Add it to your hot lye or your oils.

Thank you. I will probably try it both ways and see if there is any difference in the finished soap.
