I made Zany's no-slime castile with an "unrefined olive oil"--the cheapest olive oil I could purchase in bulk from an organic grocery store around here. It came out a gorgeous pure white. Was this likely from the oil? From the "faux seawater" that is used in Zany's recipe? A combination? I'm particularly curious because I'm experimenting with rice bran oil, which has very a very similar fatty acid profile to olive oil. Bars I've made with that so far have been much darker, but they haven't been single oil soaps. I've added soy wax to those. I'll get to experimenting on single oil rice bran soon, but maybe some of you can save me a few steps... thanks!
