Can't help technically speaking but, my take on it is that...olive does, of course, produce a lather...just not a lather that most soaps do. It's more of a slimyish (is that a word? ) lather to me (just my opinion). From researching, I do know alot of soapers add 10% castor oil to help boost the lather some. And I would think it really doesn't provide a cleansing effect per say...but I'm sure it "cleanses" somewhat and since it's great for sensitive skin, it's good not to have too much cleanse to it anyway. On a different note, I wanted to add that I've used straight plain oils to "cleanse" my face with and then use a washcloth with warm water to gently wipe it off and my skin feels just as clean (if not better feeling) than when I use soap. It would be interesting to hear what some of the expert soapers have to say. Anyway, I say go for it!!
