Please correct me if I'm wrong (as I know you will...lol). I can make a gentle bar of soap with 0 SF, if formulated, measured, and cured correctly.

Yes, I think traditionally that was the purpose of SF. It seems that many people have it in their head that SF makes their soap moisturizing. I don't agree at all as I don't think soap is or was intended to be moisturizing. Less stripping, yes, but moisturizing, no. I had an experienced soaper tell someone that superfatting under 5 was dangerous. I disagreed and even gave examples of people using 0 SF. I read on here that Kevin Dunn tested with a negative SF and the soap was not lye heavy. She wouldn't even hear it. Agreed to disagree.lol, I'm sure the more experienced people will give better answers, but I had to chime in anyway.
I thought the SF was really more to ensure the lye had all been used up more than to actually increase moisture or make a bar more gentle. So, if that is correct a 1% or so SF would actually give a better chance of getting a gentler bar of soap. Depending on formulation, which oils etc.
But, that's just my newbie opinion of course.
I would think that you could. But why wouldn't you want some wiggle room when it comes to lye concentration/saponification?Please correct me if I'm wrong (as I know you will...lol). I can make a gentle bar of soap with 0 SF, if formulated, measured, and cured correctly.
Maybe not wanting free floating oils for one. I'm not saying that I SF at zero, but I know people have and still produce a usable bar of soap. She is plain out saying that under 5 will damage your skin. From the reading that I've done, even SF at 0 most likely has some sort of SF due to most lye not being 100% pure.I would think that you could.

Who is this She you speak of?She is plain out saying that under 5 will damage your skin. From the reading that I've done, even SF at 0 most likely has some sort of SF due to most lye not being 100% pure.
Just another soaper from another forum. She's very active and gives answers/advice regularly. I guess that's why I assume she's an experienced soaper. Ya know what happenens to those who assume??? Who knows. She may even be on here. Although, if she were, I think she would know that's not true. I don't say much and when I do, it's just to genuinely try to help or offer some information maybe the OP did not know. It just frustrated me for some reason and I needed to vent. Thank you all for letting me do just thatWho is this She you speak of?
I am guessing that She thinks that some lye may not saponify if you go under 5% and therefore there would be lye pockets in the soap?
I have soaped at 1% and liked the soap, with no ill effects.
What would be the reason to soap with a negative SF? I know it has been done but I don't recall why it was done. Is it done for the purpose of drains and oils?I make gentle soap and superfat from 1-2% only higher with salt bars. I want as little free oil going down my drains as possible. I have soaped in the negative 1-3% range with no problems. But it has been found when soaping in higher negative numbers it takes more water/liquid and longer cure times to become zap free soap.
Or for making laundry soap. The free floating oils could stain the clothes.Is it done for the purpose of drains and oils?
Wow! That's crazy!Read through this thread. -30% super fat.
I keep meaning to try the recipe but haven’t had the time. The thread is super long mostly due to a discussion of method, if I remember right it cured to a basic Castile
This method only works with high water. I tried it with much less water and maybe a -30% superfat, after approx 2 years it still zapped.Read through this thread. -30% super fat.

I prefer not to wash with oil and my plumbing hates superfatted soaps.Does anybody do it because that's just how they prefer their body soap? That you know of, of course.
