Product Description
Sorbitol is a white, odorless crystalline powder with a sweet taste and hygroscopic properties. It is highly soluble in water (235 g/100 g water at 25 °C), as well as in glycerin and propylene glycol.
It is slightly soluble in methanol, ethanol, acetic acid, phenol, and acetamide solutions, but is almost insoluble in most other organic solvents.

Product Usage
Sorbitol is a polyol (polyhydric alcohol) humectant produced by the hydrogenation of glucose. It has good solubility in water but poor solubility in oil.
It is approximately 60% as sweet as sucrose and provides a caloric value of 2.6 kcal/g. Sorbitol is highly hygroscopic and has a pleasant sweet taste.
