How much citric acid for this recipe?

Did you run it through a soap calculator? I always use Soapmaking Friend and know I can feel comfortable with my recipes.

yes I did

yes, I did. The only thing I have done differently with this recipe is I added citric acid and additional lye to make up for citric acid eating up lye. I have used this recipe for years with no problems at all.

What a mysterious situation! Do you think it's at all possible your lye might be weakening? Asking because I had that happen to me a year or 2 ago. I didn't make soap for a month or two, and then made a couple of loaves that seemed to stay soft for longer than usual. I didn't worry about it at the time (though perhaps I should have!) because they did harden up several days later, and I put it down to bad measurement on my part, or rainy weather, or anything else I could think of. Then I made a loaf that failed completely. It never hardened, and had a disgusting texture — I kept one bar and it is still soft and yucky after all this time. Because it was the only thing I could think of to do, I tried a new bottle of lye and everything about my soap went back to normal!

I have no idea if that is what has happened to you, but thought I'd mention it in case you want to try a new bottle of lye to see if it helps. If someone else already asked, I apologize for missing it! Oh, and in case it's useful, here is the formula you gave listed out in SoapCalc, re-sized down to use only 16 ounces of oils. Good luck with your next batches!

thank you for the scaled down recipe! I will use it to perform testing if need be. Thats an interesting concept of the lye weakeing, I will have to check into the shelf life of l my lye. I don't think that is the case as I added citric acid to my recipe to counteract the formation of DOS, which I am struggling with.

Shelf life is subjective. You can have fresh NaOH that's been manufactured 2 days ago and if you keep the container open for some time, it will start absorbing moisture from the air, helping turn part of it into sodium carbonate. That will lower its purity and will subsequently increase the SF of the soap. It's more about storage and in what condition you got it from the manufacturer than the numbers on the label

It will get harder with time - with enough cure it will get much harder than that and it will be more or less like your other soap. But it may take months for it.

What @A-Polly says is true. @pjknight have you noticed how hot your lye solution got upon mixing? When I slowly dissolve NaOH in RT water it gets to around 93 C (pretty hot, imagine close to the boiling point of pure water). People whose NaOH has weakened usually report solution that gets to a much lower temp. Weak NaOH leads to higher SF and therefore soft soap - there's a high chance that was the case. Thanks to @A-Polly for the suggestion!

I checked the bottle of lye. It doesn't have an experation date. Ill use a new bottle. This morning I checked the soap - it is getting harder. I think it will harden up if it cures for 3-4 weeks. Also if raise the lye concentration to 35%, which lowers the water to 21.54 ounces, I think that will work. What do you think? When I added the lye for that batch, my oils and lye solution was around 100 degrees. And when it was poured together, it didint seem hot at all, and when it reached trace, ( which took a long time) it was warm. When I covered it an hour later, it was really hot and had developed a few cracks (which had never happened before), so I had to remove a blanket it finish cure.

thats good to know. I'm not going to use that bottle anymore, and open a new one, making sure its closed tightly.

If you reduce the water amount that may help with the soap being ready to be unmolded a little earlier, and it will take a little less time for the bars to get as hard as they can (according to your recipe). Sort of like making the cure go a little faster and yet not exactly, because curing does not mean only water loss, even though they are related.

So, you are buying prepared NaOH solution, mixed with water, and not pearls/flakes of NaOH? Is that correct or did I misunderstand?

No its not prepared, it's dry pearls. I have to say the soap I made with the Citric acid looks fantastic! There is virtually no ash, the color looks consistent, I'm really satisfied with how it turned out believe it or not!!! Also, that bars are hardening up quite nicely now, and I think cure may take a bit longer, but thats no big deal. I don't think I will reduce the water, as I'm pretty happy with the results so far.

That's great! You can always adjust your recipe later if needed

yes, I can adjust as needed, but for now all is good. Thank you for all your imput. I really appreciate your knowledge. I've been making soap for so many years without any problems and thought I knew it all Haha!!!! but there is always room for knowledge even for this old bird! Hoping to see the last of DOS.

You are welcome! It's all about finding the balance between what you like and what the soap likes

Hemp oil oxidizes extremely quickly once exposed to air. Consider adding enough ROE to treat the entire bottle, as soon as you open the bottle for the first time. Besides having a greater preventative effect due to adding it right away, this also has the advantage of measuring once, rather than measuring out multiple, teeny-tiny amounts for each batch of soap.

I have a brand new bottle of hemp and want to add roe to it. Can you tell me if my math is right?? 2628.74 x 0.05 =131.437divided by 100 = 1.31437 grams

If your bottle of hemp is 2628.74 grams, then your calculation should be correct, ASSUMING that your ROE has (quoting from DeeAnna’s website):

“… 5% to 7% carnosic acid content. If the carnosic acid content in your ROE is lower than that, then adjust the dosage accordingly.”

Awesome! finally got the math right!!! Yes the carnosic acid is 7%. thanks so much for the check!
