Crumbly Castile Cold Process Soap

on January 15, 2014

Two nights ago, I made a 2-lb loaf of soap with 100% olive oil.  100% olive oil soap is called castile soap.

I unmolded the soap loaf from the silicone mold after 24 hours of curing but I found that the soap was very soft — my thumb made an impression in the side of the loaf.  So, I waited until 36 hours after I made the soap to cut.  Unfortunately, the soap was very crumbly.  I took my dilemma to two cold process soaper’s groups on Facebook that I am a part of.  “Did my soap crumble because of a big temperature difference between the hot lye water and my room temperature oil?”

I actually misspoke in the video. I did NOT make a big batch and split it into two. I actually made two separate 1-pound portions. I had cooled lye water to mix in the first portion. Then I was in a hurry with the second portion and I used hot lye and I was wondering if maybe using hot lye water with room temperature oils would make the soap crumble.  I layered them together in the mold. I poured one layer of one and then I poured one layer of the other. Back and forth like that. They were at a light medium trace so they swirled a little bit in the mold.

One person asked if the soap was lye-heavy and suggested that I do a zap test (which is basically touching the soap to the tip of your tongue to see if it zaps you if it has too much lye as opposed to just tasting like soap if there is NOT too much lye).  It’s not lye heavy because it didn’t zap me.

Another person asked if it went through “gel phase.”  I am quite sure that it didn’t because I did not insulate the soap and it rested in my rather cool Ohio basement.
