I used a lady's salt scrub at a show last year and loved it. Made my own for awhile and liked it too only now I want to try an emulsified scrub so it doesn't have to be stirred. I see Barb's recipe uses and 'emulsifying' conditioner, what is that and where do I get it? And what kind of preservative do you use? If I'm making this for myself to I have to have a preservative in there? With what I made before we used a spoon to scoop it out so there was no dipping into it with wet or dirty fingers so don't you think it'd be safe for our own use?
