I've never used pomace. I use food grade pure, natural oo or evoo in soap. I'm glad to know the extra light oo works for you and that it will work for Diana. It's not cost effective for me beyond cooking and salads. My local supermarkets carry small bottles of it and I would use a lot for soap. Cha ching! (Sound of cash register adding up.) Super market oil gets real pricy for soap. Plus I already have one soft oil in a small % in my recipe and don't care to add another. And actually, what you said about your soap being softer initially makes me wonder even more if the extra light oo is mixed with something else. Thanks for your concern and wanting to help, though.
Diana (and anyone else) I don't know if you have a BJ's club near you but they're currently running a 60 day free membership special - no strings attached. IOWs you don't have to pay anything up front or join at the end of 60 days. A little over a gallon of pure, natural (Bertolli) OO is $24.99. I figure with what I'm saving on shipping from my normal supplier that works out better for me for now so I'm going to stock up. I didn't ask about the extra light OO when I called.
Costco may have better prices. I think Spotted Cat said she was paying $18.99 for a gallon of food grade pure, natural OO. I'm not a Costco member because there's not one near me. Just tossing out a few ideas that people who are on the olive oil hunt might want to check into.
