My main reason for changing from olive oil to rice bran oil was that I find olive oil soap slimey. And Daddy needs his bubbles! I use RBO at 23% and according to soapcalc, the hardness # is 48 on a range of 29-54. People tell me my soap lasts a long time but I don't have any exact stats for you, sorry. I can't really compare it to olive oil anymore because it's been several years that I switched over.Hi Zing, I’m just playing around with my base recipe in an attempt to increase longevity of my bars and have found on the calc that subbing some of my olive oil for RBO helps to hire the palmitic which is nice as I can also get RBO fairly reasonably priced here but just curious as to how it hardens in time….. would you say RBO is comparable to OO in terms of hardness and longevity? I intend to make several batches to play around with this, Including a full replacement of olive oil…… but just curious before my experiment begins!!
I should add that I have used RBO at 10% before and enjoyed it in my bars but have never gone higher than this and with my new recipes I would be looking at 15-45%…..
