lol, I'm sure the more experienced people will give better answers, but I had to chime in anyway.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.
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.
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.
