I don't quite understand? Batch size is directly proportional to needed amount of liquid, so the vinegar as %PPO is the same, regardless of batch size, and so is the SF increase.

You are right, and I even thought after posting that I should go back and fix that, but I didn't because it was midnight & I was too tired.

What I left out that is more important in relation to why it isn't worth the bother for me to do the extra calculations is that I use my masterbatch lye solution [50%], so what I add as additional liquid has very little impact on superfat.
Even while traveling, I bring my masterbatch lye solution along, so I rarely make up a whole new solution while on the road. I do often have to buy drinking water and I find that distilled water is often cheaper than most bottled drinking water, so that's what I buy if I am also making soap.

I've done the calculations in the past, and the SF difference really is negligible in this situation (using mb lye.)

For example, I have done this many times and a 500g of oils batch using mb lye @ 0% SF & [33% Lye], the additional liquid needed is 69 grams. If I put 69 grams of vinegar instead of water, the difference of actual NaOH is only 2.5 grams (5 grams of the masterbatch, which is half water). 2.5 grams of NaOH is not going to change the SF enough that I need to bother with adding a little extra. (It actually only increases about 3.5%, but as far as I'm concerned, it is not noticeable). If I'm off a gram or two when I weigh out my oils, I don't sweat it, neither do I for a gram or two of water. So the gram or two of NaOH is not going to make or break my soap IMO and IME.

Call me sloppy, but I don't run a lye purity test everytime I make soap either. And we all should know that there are variables regarding lye purity and scale accuracy that impact SF as well, which is why I don't feel that a gram or two is really something to worry about.

NB:
IF I was faced with completely replacing vinegar for water in my lye solution, I would not because I did that once, and the soap came out so brittle that I decided never to do that again. It was the only time I made up a fresh batch of lye solution using only vinegar and no water at all.

Does everyone really use distilled water for making soap? I’ve used filtered tap water only, and it’s been fine. I have a decent 10 stage filter. But, I can’t quite imagine having to buy bottled water for soap. Am I missing something, or messing up?

I cut my soap from 2 days ago. I'd forgotten how sticky new soap can be. 40 bars of patchouli. Fortunately I still have about 20 bars left from the patchouli batch I made 2 years ago, so this new batch can take as long as it wants to harden. Someone asked if I could post pictures. Here they are. (They're not going to win any photography trophies.)

I've made a lot of soap in my life and using distilled water has never crossed my mind. Maybe I'm missing something too?

I sometimes use distilled but mostly use tap water; I've never had an issue. We do have soft water here so I don't know if that makes a difference.

My mom made soap for years and she only ever used tap water, with no issues either.

If I have the chance to avoid heavy metal contaminants like copper, zinc or iron (from the plumbing) to get into soap, I'll do. Ca/Mg (water hardness) doesn't accelerate rancidity, but doesn't belong in soap either, IMHO. Bad enough to have these in soap scum all around the sink. Neither I'm particularly comfortable with the indefinite amount of carbonate in tap water (reacting with lye to form lime or soda ash).

Where I live we have very hard water as we have a lot of limestone in the ground (we can't have basements because the ground is too rocky and shifty). I was using distilled water until we had a shortage in the winter and I switched to aloe vera juice.

I use tap water. We are on a well and have a whole house filter that filters out sediment and metals.

Don’t know if was ants in my pants or getting too big for my britches’ but ATTEMPTED to make ONE batch soap batter; Dividing batter for two different scents, two different colors. . WHAT was I thinking?! Needless to say had to move way too fast & during clean up found a dish of kaolin clay + scent UNUSED for the blue batch. OyVey!

I used distilled water when I lived in the desert and we had to, as the water was so crazy hard. We now have a well and that water works PERFECTLY! And tastes so much better. I figure if tap water works in your area, why make things harder? (Hard water... Dumb joke.)

Massaged the heck out of some stiff soap dough and made some embeds for two different soaps. Mixed my lye, and hoped I’d get to making them today. But then I got too tired, and that’s when I mess up, so I figured I’ll do that part tomorrow when I’m fresh. I steamed a couple of ashy soaps and hope they’ll be dry enough to package tomorrow for the farmers market on sunday.
And, I made some cute bath bombs for the farmers market. But, my color combos were off, and the resulting water when the bath bomb is spent isn’t the prettiest. So, I’m not sure what to do. They’re so stinking cute though! And, they perform great!

Life has been a bit busy lately so I haven't done much soaping. A month ago I tried infusing oil, one with turmeric and and the other with dill weed. I was going to do the grocery store soap challenge but I didn't use my head and added shea butter since I was making it for my mom. I also remembered I didn't have anything to use as a soap mold. I was a bit disappointed to see that the dill weed did nothing for color. I was hoping for at least a faint green color since it did color the oil a faint green.

Anyway here it is. Please don't mind that I didn't clean them up. Mom likes the natural look.

It’s not really a soapy thing, physically, but I had a job interview today and was asked what hobbies I had outside of work. I said I make soap! It seemed to be a good answer.

I have watched this ten times and it still makes me chuckle. So that’s my soapy thing for today.

Same. Had to share to my Instagram story. Too funny & so darn true!

Made orange soap dough to start some autumn soaps.

Yay, interview! Fingers crossed for you.

I had an interview on Wednesday and my soap came up in the conversation. I was being interviewed by three people simultaneously and one of them was attending via Zoom. That person looked me up on LinkedIn while the interview was happening and asked me about my soap business (because I included it in my profile).

I responded with, “How much time do you have?”

They were all nerdy engineers so I did my best to talk about the science of soap. It was super fun!

@The_Phoenix Nerding out about soap during an interview sounds like a great way to relax! I bet you nailed it!

It really was!

I joked that at home I’m allowed to talk about soap for no more than two minutes, especially at dinner.
