100% beef tallow soap

[Nanditasr]

@Vicki C Did you make the 100% tallow soap? I’ve been testing mine, which I made with 10% KOH. It’s okay, but it’s not what I would call lovely. The bar will make lather if I work at it, but even with dual lye it’s a very hard bar of soap. In use the bar is so slick that it’s hard to hold on to, which is not at all what I expected. It’s like hard shiny plastic coated with a film of soap. I wonder if my hard water is a contributing factor? Maybe I need to up the KOH for the next batch?

eta: I’ve been scouring the threads and have seen cautions about exceeding 10% KOH, but based on the firmness of the soap, I think I would have better results using 13-15%. The KOH I’m using has been fine in other soap recipes with the purity set at 90%. On the other hand, I just recently bought a new box of tallow and noticed right away that it’s a bit harder than the tallow I was using over the last year. Perhaps that’s a contributing factor and I’m ending up with less than the calculated SF, which was set at 3% for the initial batch. I could make two small test batches, one with 15% KOH and 3% SF and one with 10% KOH and 6% SF for comparison. If anyone has any other ideas or suggestions, please let me know. I will report back!

I have always had the problem that the tallow ones crack and look ugly soon. And don't lather much (not that this bothers me) -- but the cracks and splits bothered me. Just on a whim, I tried flaxseed gel instead of water, and 20% KOH. Citric acid as chelator. I used 90% tallow and 10% castor oil; No coconut oil because it dries out my skin. I think this gel acts like a kind of glue -- no more cracking! And lathers better too.

@contrinokathy Lots of bubbles! Do the bars bubble that well in use? What is your usage rates for the additives? I added sugar at 1% TFW which equates to a bit less than 1 tsp ppo.

Yes. They are amazing. 1 tsp ppo but honey I use up to 1 tbsp ppo

My dual lye tallow neem soap is fabulous. No issues at all and lather is amazing

Lather for this 85% evoo/15% neem oil dual lye soap is amazing even with cold water using our hard water. No slime Just an amazing workaround for a single ingredient soap.

Doesn't it smell strongly of neem?

Not at all. Even my unscented soap with neem is without the scent of neem. It’s a fallacy to believe neem oil makes neem smelling soap

Just made 100% tallow bar for grandson. Added a small bit of spun ivory colored alpaca wool to lye mix.
This soap has marvelous lather rich and compact. Very gentle on skin.
Could also try adding silk. I used alpaca as grandson is on a carnivore diet.

Does the alpaca wool dissolve? What's the purpose. Fascinating

I made a 85%/15% tallow/neem oil 95%/5% sodium/potassium and the soap is incredible. I live in hard water country and I don’t have any problems. I always add beer powder, honey powder or pine rosin powder to up the lather but it’s amazing. It made the same version in a lard/neem recipe, olive oil/neem, and Shea/neem. The olive oil and Shea are the ones I love the best. I use the olive oil/neem for my hair and it is amazing.
I love this so much I am including them in many of my soaps. It is a great technique for one or two ingredient recipes. I have attached the video of the lather immediately after taking the soap out of the crockpot.

When do you add the powders? And do oil or water/lye? Thanks.

I can answer the question about the alpaca wool ~ yes, it dissolves when addedto the lye solution. Like adding silk fibers, you add a very small amount and snip or tear into very pieces so it does dissolve thoroughly. It adds a very silky texture to your soap.

Thanks! That's fascinating. Maybe I'll try that. Must be all the collagen and silica

fascinating! Thanks for the tip. Silky texture sounds good to me. I'm making a tallow soap for some carnivore diet folks. Really interesting idea thank you

I hadn't thought about the hows and whys of it, but now that you mention it, that would make sense As for measurements and more specific how-tos, you can search the forum. There are plenty of discussions (most likely with links to other resources) with everyone's advice on how to add fibers (even spider webs ) to soap recipes. Happy soaping!
