Yesterday me and Melladh tried to make cold process soap for the first time. (And I guess the last time..). The sodium hydroxide developed some nasty fumes we didn't really expect, at least not that much of them.. But that's not the problem right now.. The problem is that the soap thickened, maybe a bit slow, but it thickened. But after about 5 hours it still hadn't reached trace! Melladh had gone home and I had to go to bed due to high fever.. I didn't want to leave the soap in the pot so I poured it into the molds and went to bed. This morning the soap seems to be a bit liquid still but a dark spot has shown up in the middle and has spread towards the edges of the mold. I guess this is the gel phase? Is this a good sign for our soap?

What I'm really wondering now is:
1. Can I wait more than 24h before cutting it up?
2. Do I have to cut it if we're going to rebatch it?
3. What to do if it doesn't want to turn solid? Can I try to pour it into the sink?

How were you mixing it?

Did you use a hand held stick blender? Or was it all done by hand?

What was the exact recipie??

Its kind of hard to tell not knowing how it was done, what ingredients you used, etc....

It was mixed by hand, I stirred continuously for over an hour, then I stirred now and then. Due to all the fumes when I poured the NaOH in the water I was stirring outside for at least 30min, and it wasn't very hot weather.. Maybe 5C. But the pot was warm all the time.
The recipe:
610g cocos fat (I think I managed to take almost 615g)
670g sunflower oil
670g olive oil
240g NaOH
930ml water

It is supposed to be a superfatted soap I think. Because there is a soap in the book I got the recipe from that's got almost the same amount of fat, but much more NaOH.

Now all the soap is light-coloured. Yesterday morning it had quite a bit oil on the top, but when we went to bed some of the oil on top seem to have disappeared and the soap under it seems to be solid. It's still sitting on my kitchen counter in it's mold.. I don't really know if I should cut it up or not while it's got some oil on top..

Ok I just ran it through the lye calculator and according to the oils you added you SHOULD have used at least...

265.80 grams of NaOH (lye) to be 10 % fat OR
295.34 grams of NaOH (lye) to be  0 % fat

and

the water should have been ONLY
489 ml - 733 ml at most!!

So, it looks like you used TOO much water, and NOT enough NaOH (lye)

And you definately want to use a stick blender........!!!

That would make life much easier! Good Luck!!

(I just wanted to add that there are others here that know much more about soap making than I do, and I hope someone can help you save your soap)

Ouch  Undecided And I thought you could trust the recipies in the book.. But I guess I was wrong. But this should at least mean that the pH shouldn't be alarmingly high if the soap is still ok. All lye have got fat to react with, and the oil on top should be left over from the reaction.

Thank you so much for your answer!  Smiley

Handmade Soap by Tatyana Hill, but translated into Swedish.

A small update on the soap situation (if anyone is interested..): I did cut the soap a few days ago. It was solid but very soft. The pieces from the larger mold seemed to be a bit darker (and harder) then the ones from the smaller one. I've left them in a box now and we'll see what's happened to them in a month or two  Wink
