Glycerine(ol) is a trihydric alcohol, (not a carbohydrate) and is the building block of all plant oils and nearly all animal fats. Without a
humectant to hold moisture, any bar would be a rock-solid brick within hours of production. Glycerine is the only effective humectant that can be used by non-secretors, since it can be shunted to either fat metabolism or glucose production, depending on metabolic status. Glycerine can be a carb on occasion, a fat precursor on occasion, a phosphoglyceride precursor on occasion, and it can simply pass through the body unused. For non-secretors, this is perfect. Thus, although it is there for moisture retention, it also tends to optimize fat<->carb<->fat conversion which is genetically a problem with non-secretors.
