Product Application of Sorbitol CAS#50-70-4
Sorbitol is a polyhydric alcohol (polyol) humectant produced via glucose hydrogenation. Highly soluble in water but poorly soluble in oils, it delivers around 60% the sweetness of sucrose at 2.6 kcal/g, with strong hygroscopicity and a pleasant sweet taste.
