Hi. I am new here and am trying to get some idea's on making shower gel. Can anyone tell me a good site to by shower gel bases that are all natural? I have looked at a couple of sites, but it seems to me like they are not all natural. Also, do you need to add a preservative to the bases? Or is it better to just make the gel myself? I'm a little overwhelmed now that I have done some reading here. Thanks!
