CAS Number 98201-93-5
Chemical Formula C6H14O6
Description
White, odorless, sweet-tasting powder.

Sorbitol is a sugar alcohol. It has two thirds the calories of sugar, and is not as sweet (60% as sweet as sugar). It is poorly absorbed by the body, so it does not raise insulin levels as much as sugar. It does not promote tooth decay.

Sorbitol and mannitol are isomers, substances with the same chemical formula, but a different shape.

Sorbitol can be described as a glucose molecule with two hydrogens added. The two extra hydrogens are on either side of what used to be the double bond connecting the oxygen to the carbon, which is now a single bond.

Sorbitol occurs naturally in fruits and vegetable. Most sorbitol in foods and other products is made from corn syrup.


Uses
Sorbitol is used in low calorie candies, and in many foods as both a sweetener and as a humectant (moisture retaining ingredient).

Sorbitol is used as an emollient (skin softener) in soaps.

take a look at the dangers in cough syrup re to much, thats a good headline, you can over-dose.


Sorbitol, also known as glucitol, is a sugar alcohol the body metabolises slowly. It is obtained by hydrogenation of glucose changing the aldehyde group to an additional hydroxyl group hence the name sugar alcohol.

Sorbitol is used in various cough syrups, and is usually listed under the inactive ingredients. There is a growing opinion within the medical community that it should be listed as an active ingredient, because too much Sorbitol (about 50g or more for adults) can cause severe gastro-intestinal problems.

Sorbitol is a sugar substitute often used in diet foods (including diet drinks) and sugar-free chewing gum. It also occurs naturally in many stone fruits. Sorbitol is also referred to as a nutritive sweetener because it provides calories or energy to the diet - 2.6 calories (11 kilojoules) per gram versus the average 4 calories (17 kJ) of sugar and starch, while retaining 60% of the sweetness.

Sorbitol is produced naturally by the body, yet sorbitol is poorly digested by the body. Too much sorbitol in cells can cause damage.

Diabetic retinopathy and neuropathy may be related to excess sorbitol in the cells of the eyes and nerves. The source of this sorbitol in diabetics is excess glucose, which goes through the polyol pathway. Ingesting large amounts of sorbitol can lead to some abdominal pain, gas, and mild to severe diarrhea. Sorbitol can also aggravate irritable bowel syndrome and fructose malabsorption.

Sorbitol is often used in modern cosmetics as a humectant and thickener. Some transparent gels can only be made with sorbitol as it has a refractive index sufficiently high for transparent formulations. It is also used as a humectant in some cigarettes.

Sorbitol is used as a cryoprotectant additive (mixed with sucrose and sodium polyphosphates) in the manufacture of surimi, a highly refined, uncooked fish paste most commonly produced from Alaska (or walleye) pollock (Theragra chalcogramma).

Sorbitol is identified as a potential key chemical intermediate [1] from biomass resources. Complete reduction of sorbitol opens the way to alkanes such as hexane which can be used as a biofuel. Sorbitol itself provides much of the hydrogen required for the transformation.

19 C6O6H14 → 13 C6H14 + 36 CO2 + 42 H2O
The above chemical reaction is exothermic and 1.5 mole of sorbitol generates 1 mole of hexane. When hydrogen is co-fed no carbon dioxide production takes place. The advantage of hexane as a biofuel over other well established biofuels such as ethanol is that hexane easily separates from water. In fact, the energy required to distill ethanol from water in the bio-ethanol production process eliminates much of the energy advantages.

You could always check Wikipedia (www.wikipedia.com), but don't use it as a direct resource for your research, it's like copying from the encyclopedia. The Wikipedia entry has a ton of external links in it though, they should be helpful for gathering more information. Use it as a general way to get to know your topic. You can Google things like "sorbitol", "Sweeteners", and "sugars" to find some more resources.

I would recommend that your research be focused pretty tightly though; "sorbitol" is a big topic, and your documentation and writing can be muddy if you try to cover too much ground at once.

I did a search on Yahoo....sorbitol vs. sugar and this one looks good
http://www.cbc.ca/consumers/market/files/food/sugar/
give it a try and good luck with your project.
On a person note, sorbitol products contain a warning, something to the effect of, consuming too much of this product may cause a laxative effect....trust me, it does too.
