I offered to make it.I usually use my nose when it comes to rancidity, it might be better to buy small batches of grapeseed oil to make the soap and to use quickly once cured. I had a quick google and couldn't find anyone that mentioned using it as a one oil soap.

I've had a few customer requests that I've made for people along the way. For example, I made 100% almond oil (liquid) shampoo that turned out better than expected! Quite nice, actually, and had good, if not copious, lather. I imagine I could try the same with grapeseed oil, which by the way, I'm also quite fond of... I use it in lotions and I cook with it daily.
