Trouble with Superfatting
I am having trouble figuring out the superfatting amount. I made my first soap but it seems I got it wrong.
I used soapcalc and I put 5% in for the superfat. My recipe was castor, palm, olive, coconut and I put my castor amount to 5% and I added it at trace.
So... now I read everywhere that I shouldn't add it at trace but put it with my other oils.
Help me to figure it out how much superfat am I have now?Answer:
Understanding how the superfat works can be confusing, especially since the process has evolved over the last decade or so and information on the web varies.
If you put the 5% superfat amount into Soapcalc and just held back that amount of Castor oil until your soap reached a light trace, your soap should be alright as long as you mixed it in well.
You do not need to do this in the future though. When you enter the superfat amount into Soapcalc, the program will reduce the amount of lye needed which then leaves your soap with 5% unsaponifed oil. Setting the amount in Soapcalc is all you have to do.
Adding the oil later does not change how much oil will be left unsaponified. The saponification process continues after the soap has been poured into the soap mold so any lye still looking for oil to bond with will find it then.
One problem with adding oil after the soap traces, is that people tend to add more oil than what is in the recipe which will increase the superfat. This isn't bad if you only add a little oil but if you add quite a bit, you can end up with an oily soap.
Hope this clears it up for you,
