Facts About Glycerin



Some soapmakers which make and sell soap better than store-bought said like this while being asked: "Because of the natural glycerin. It is a humectant, meaning it attracts moisture to your skin and  is a natural by-product of the soapmaking process and while commercial manufacturers remove the glycerin for use in their more profitable lotions and creams, handcrafted soap retains the chemcial in each and every bar."

Then you may interested in what is glycerin.

Glycerin(or glycerine, glycerol, with the molecular formula C3H8O3) is a neutral, sweet-tasting, colorless, thick liquid which freezes to a gummy paste and which has a high boiling point. It can be dissolved into water or alcohol, but not oils. On the other hand, many things will dissolve into glycerol easier than they do into water or alcohol. So it is a good solvent.

The fact that is also easily absorbs water from the surrounding air means that glycerin is hygroscopic. If you were to leave some in the open, it would absorb water from the surrounding air to eventually become 20% water and 80% glycerine. If you were to place a small amount of pure glycerol on your tongue, your tongue would blister because it is dehydrating. When beauty products containing glycerine are used on skin that is well moisturized, it can help keep that moisture in.

The process of removing the glycerol from the soap is fairly complicated (and of course, there are a lot of variations on the theme). In the most simplest terms: you make soap out of fats and lye. The fats already contain glycerin as part of their chemical makeup (both animal and vegetable fats contain from 7% - 13% glycerine). When the fats and lye interact, soap is formed, and the glycerol is left out as a "byproduct". But, while it's chemically separate, it's still blended into the soap mix.

Glycerine has lots of uses besides being used to make nitroglycerin. Some uses include: conserving preserved fruit, as a base for lotions, to prevent freezing in hydraulic jacks, to lubricate molds, in some printing inks, in cake and candy making, and (because it has an antiseptic quality) sometimes to preserve scientific specimens in jars in your high school biology lab.

This liquid is popular in beauty products because it is a humectant — it absorbs ambient water. This means that it can help seal in moisture. Not only is it used in the soap making process, it's a byproduct too. Because of their high glycerin content, the soaps are very moisturizing to the skin. Unfortunately, this also means that the soaps will dissolve more rapidly in water than soaps with less glycerol, and that if the bar of soap is left exposed to air, it will attract moisture and "glisten" with beads of ambient moisture.

These downsides, however are more than compensated by the emollient, skin loving and gentle nature of this soap which is especially good for tender skin and children.
