Ohh I'm sorry...No. I meant adding "about 10-15% of alcohol (from leftover hand sanitizer 70% ethyl alcohol" to the batch. ???
I found this: Homemade Glycerin Soap Recipe (From Scratch)
I was intrigued and wanted to try to make glycerin soap.
Hand sanitizer alcohol was what I had so I made a dish soap. It was very interesting how cleansing, it cut through fat so well, and had nice bubbles.
It was CO+Lard or Tallow. Citric acid, sugar, and the alcohol (hand sanitizer) at the end.
I searched a lot and I still to this day I do not know what the alcohol does in the soap chemistry. I just know that it is a solvent.
I found a lot of videos from Brazil that people use alcohol in their soap. It's very common there.
Even without the CO and using pure lard the alcohol soap performs really well for cleaning and laundry.
You should give it a try
