Hello! I finally managed to make my first soap. YAY! I uswed 64 oz olive oil and 28 oz coconut oil. My sheep milk was frozen solid even though it had sat out for over an hour when i added the lye....I eventually got the heat on the lye/milk up to 85-90 before I added it to the oil that was at 100. I got things to trace and it all looked good...but it was a little greasy feeling and rather soft.
3 weeks later I checked on its curing and it STILL feels greasy and is a bit soft.
Why did it turn out so soft and what can i do next time to prevent it? if I cure it near a heat source will it harden a little faster?
I am not sure what went wrong. I do have a question though, how much lye did you use? I put your oils in The Sage lye calculator and it suggested for your recipe to use 23 -34 oz. of liquid and for 5% superfat that you use 13.04 oz. of lye. I am wondering if perhaps you may not have used enough lye or too much liquid.
Also, you have a large amount of olive oil, 69% in your recipe. Could this be a problem? I don't know, but I don't think it is, I use 62.50% olive oil in my recipe and my soaps are generally very firm in 1 to 2 days.
I think your temps for soaping were ok. I make goat's milk soap and I always use frozen milk and add my lye to that, so I soap in low temps.
Did you use a fragrance oil and if so how much?
Those are some of my thoughts on the matter. I hope someone else will reply and be able to help you find an answer to your problem.
Can you tell us how much milk and how much lye you used in the recipe? Next time try a one pound recipe and if it doesn't turn out you won't have lost so much. You might try cutting the soap up and doing a rebatch in an old crockpot. Here is where I learned to rebatch. Since your soap is soft, you won't need a lot of liquid.
I ran your recipe through SoapCalc and it looks like the recipe should have used 13.1 oz of lye instead of 10 oz. Always run any soap recipe through a lye calculator before using. SoapCalc is my favorite.
