Okay, has anyone ever noticed that if you evacuate a bar of glycerin soap in a cabinet or everywhere too long, it "sweats" out white chunky stuff that sits on the surface of the bar?

What is that stuff? Why does it get "sweated" out?
Sealing stainless steel?
Answers:    The white chunky stuff is dried humid nouns mixed with soap. It is created by the fact that the glycerine soaps contain greatly of humectants which attract moisture from the air (your bathroom is a very humid place) and later the moisture actually sits on the top of the soap. So it isn't the soap sweating it is the moisture from the air sitting on the soap and drying.
