Xylitol is a sugar alcohol used as a sweetener. It has the chemical formula C5H12O5.
Xylitol will react with nitric acid to yield xylitol nitrates.
Xylitol is a white crystalline solid, with a sweet taste similar to that of sugar, though it has a slight fruity flavor. It is soluble in water (200 g/100 ml at 25 °C), methanol (6 g/100 ml), ethanol (1.2 g/100 ml) and pyridine. It is insoluble in ether. Its melting point is between 92 to 96 °C, and the boiling point has been determined to be 345.39 °C. Xylitol has a density of 1.52 g/cm3.
Xylitol is available in most hypermarkets and health food stores, usually as 99-99.9% pure. The price depends on the brand.
Xylitol can be extracted from various fruits, though this process is intensive and is much cheaper to just buy it from stores.
It can also be prepared through the hydrolysis of xylan, a polysaccharide found in wood. This gives xylose, which can be reduced to xylitol.

Xylitol has no known toxicity or carcinogenicity, and is considered safe by the FDA. It has an extremely low glycemic index of 7 (glucose GI is 100) and has been shown to be useful in reducing tooth cavities. Xylitol does however have laxative effects, though it's possible to build up resistance after several weeks of consuming it.
Xylitol however may be fatal to dogs and birds.
In closed containers.
Xylitol does not pose any danger to the environment and can be poured down the drain or dumped in the soil or trash.
