Hi
@Saltynuts!
I read a lot about lower superfat soap. Mainly because of ways to reduce soap scum.
If you've heard of ZNSC (zany no slime castile) it uses 0% super fat. It makes a very nice soap.
If you let the soap cure, the soap will get milder.
A 0% soap will perform at the maximum soaping/cleaning capability.
Here is some info for you to read:
P% superfat soap oil tests

And here is a thread with more info about 0%superfat
https://www.soapmakingforum.com/threads/zero-percent-superfat.62504/
But you obviously didn't want any unreacted NaOH in the final soap
I would be more concerned about undisolved lye crystals in the soap then 0% superfat
Maybe make the soap with NaOH excess, then dissolve it in water, then add acid, shake shake shake,
If you add acids, the acid will react will the lye and not with the oils.
You will have superfat
our lye is not as pure as we think, so we have superfating even when we think we are not
There is unsaponifiables in the oils, they behave like superfat
So in order for you to do a true 0% superfat, like for a cleaning, laundry type of soap, your superfat will need more excess lye than you think
Personally, for a body use soap I use 2%- 3% superfat. For safety and because it feels nicer to use. I also use high conditioning and low CO recipes
Also check out DeeAnna's classic bells website.
It has amazing information.
Thank you
