I made a nice body wash from a plain Dr Bronners castile soap bar by shaving it and stirring it into some heated distilled water. I added aloe, jojoba, and some essential oils. I used Xantham to thicken, although I think I'm going to look for something better as that separated a bit. MY question is, the soap is not quite as lubricated for lack of a better term as I would like. It seems a little sticky when lathering. Could I add some simple olive oil to the mix to fix this? If so, which type/kind of olive oil? Thanks.
