A humectant is used mainly to retain moisture making it a part of hygroscopic substances(a group of molecules that holds water molecules from the surrounding environment). It is a part of many groups including hydrophilic, hydroxyl, amines, carboxyl, and ester because of its ability to form hydrogen bonds with water molecules.

Unlike a desiccant, a humectant attracts and holds moisture in the air, by drawing water vapor into/beneath an objects surface. Because of this trait humectants are useful in many ways including as food additives, topical dosage forms, cosmetic and personal care products, and some tobacco products.

Examples of Common Humectants -Sorbitol, glycerin/glycerol(sugar alcohols) -polydextrose -glycol
