What are Humectants (Glycerol, Sorbitol)? Humectants are substances that attract and retain moisture, making them essential in various industrial applications. Glycerol and sorbitol are two widely used humectants known for their ability to maintain moisture levels in products, which enhances texture and shelf life. Glycerol, a colorless and odorless liquid, is derived from fats and oils, while sorbitol is a sugar alcohol obtained from glucose. Both compounds play a crucial role in preventing dehydration in products, thereby preserving their quality. These humectants find primary uses in the food, cosmetic, and pharmaceutical industries. In food production, they improve texture and moisture retention in baked goods, confections, and dairy products. In cosmetics, they are commonly used in lotions and creams to maintain skin hydration. The pharmaceutical industry utilizes glycerol and sorbitol as excipients in various formulations. As industries increasingly prioritize product quality and longevity, the demand for effective humectants continues to grow, making glycerol and sorbitol vital components in product development.
