I'm in need of some professional help....(not mental, :? thankyou :? ) i am wanting to make some salt scrubs the simi liquid kind. I have several good sounding recipies but my question is what about a preservitive? no mater what i put the scrub in im sure someone will manage to get water in to the jar, i dont want it to mold, so what should i do? is there just a general preservitive i can add that would take care of the problem? and what about sugar scrubs? hellllllppppp..
