Sorbitole 

Sorbitole, or glucitol as it is sometimes called, is a slow-metabolizing sugar alcohol derived from fruits, corn and seaweed. It's a sugar substitute found in foods such as frozen desserts, sugar-free chewing gum and diabetic candies. Sorbitol is only about 60% as sweet as sugar, however. It is also used as a thickener and moisturizer in beauty products. Since it's very slow to be metabolized by the body, sorbitol does not cause insulin levels to increase as much as sugar. It also doesn't lead to tooth decay and is used in many sugar-free cough syrups. It is a popular addition to gel toothpastes as it helps add transparency.
