I went back through the soap binder today looking for the laundry soap recipe(the printer is out of ink), and happened to look at the bar soap section. I have 3 batches that did not include castor. I grabbed those, and the one that had sugar, but no castor.
And yes, sugar makes bubbles, but castor adds "stickiness", and strength to the bubbles, helping them stick together and stay up longer.
