Sorbitol
Sarbitol a hexavalent sugar alcohol is a common constituent in many edible fruits. Although known since many decades, it could not find any commercial applications, as its extraction from fruits was very expensive. Its importance was recognized later only after the large scale economical manufacture of sorbitol from the commercially available glucose became possible by catalic reactions with hydrogen.

Applications:
Commercially, Sorbitol is generally marketed in the form of 70% solution, as a clear colourless or fainty yellow syrupy liquid, with a sweet cooling taste. It is chemically classified as a polyhydric alcohol. Being a hexavalent alcohol, it is closely related chemically to the bivalent glycol, ethylene glycol. However, unlike glycols and glycerol, sorbitol occurs as a white solid substance. In an aqueous solution of 70 % of w/w strength.To summarise the principal advantages which sorbitol exhibits over other polyols are:
