Nenah,

      Glycerin is metabolized more like a carbohydrate, not a fat although it 
doesn't affect the blood sugar levels as does pure carbs.  You can get some 
good info here.

  Subject: CS>question about glycerin for you chemists


  I have a question about glycerin, an oil-like substance made from vegetable 
oil and the byproduct of soap making. Many soap makers remove the glycerin and 
put it into hand creams because of its moisturizing properties.

   

  My question relates to the activity of the glycerin versus coconut or any 
other cooking (edible) oil.

   

  If I put coconut oil or sesame oil onto my skin, the oil will soak through 
the skin and get into the bloodstream and the body will process it as it does 
any other fat that has been eaten.

   

  Will the body do the same thing with the glycerin? Or is glycerin -- despite 
its oily consistency -- even considered an oil/fat in the way that the terms 
"oils" and "fats" are commonly used?

   

  This is very important to me, so I'd appreciate your responses.

   

  Thanks in advance.
