OK, I did the math and for the batch that produced the sweating, PippiL is using one ounce of FO PPO or about 6.25% of base oils. This is a pretty standard usage rates for FOs. I personally tend to use less (4-5% or roughly .6-.8 oz/PPO) but that's neither here nor there.
At the risk of sounding like a broken record, WHICH FOs are you using? Even if they are appropriate for use in CP, some FOs can cause heating issues. If you post what you used, perhaps somebody else with experience with that FO can offer more specific advice.
ETA: you mentioned that your goat's milk batch had this problem also, the milk might contribute to heating. And you said that this batch accelerated when you did your column pour.
So I'm betting that it's an overheating problem.
Are you using wood or silicone molds?
BTW, it's perfectly OK to peek at your insulated soap. I check after a half an hour and if nothing seems amiss, I check at hour intervals after that. When gel is complete, I throw off the insulation and let the soap cool.
I did a pumpkin puree soap once that completely gelled and separated within 20-30 minutes. Therefore, I peek.
One more thing, I have noticed that when I use castor oil my soap can sometimes appear a little greasy or sweaty. Usually temporary. But I don't use castor in soap much anymore.
HTH!
