There are a few special considerations when mixing your lye solution for soapmaking. I use citric acid at 2% of the oil weight in my recipe. Citric acid works as a chelator by binding to some of the metal ions in hard water resulting in less soap scum and, some say, more bubbles. Citric acid neutralizes some of the lye, so I like to use a lye calculator that will do those calculations for me. Soapmakingfriend.Com will do this. I also use powdered sugar and aloe juice instead of water. You can see in the first clip what happens when I add lye to room temp aloe that had citric acid and sugar dissolved into it. There's a very violent exothermic reaction that can be very dangerous!
To mitigate the very high temps of the reaction, I froze some aloe and added that to my dissolved citric/sugar/aloe solution. Now when adding the lye, the temps remain at a safe level and there's little risk of violence. Of course it's best practice to suit up for safety with long sleeves and eye protection.
I'll cover these containers of premeasured solution to use for the next couple of weeks. As long as it is kept covered, premeasured lye solution will keep at least several months (that's as long as I personally have kept it).
I hope these tips will help you! If you learned something and you enjoy this type of content, let me know in the comments below and please consider subscribing.
