Origin: [L. humectans, p. pr.]
A humectant is a hygroscopic substance used to keep things moist; it is the opposite of a desiccant. It is often a molecule with several hydrophilic groups, most often hydroxyl groups; however, amines and carboxyl groups, sometimes esterified, can be encountered as well. They are used in many products including food, cosmetics, medicines, and pesticides. A humectant attracts and retains the moisture in the air nearby via absorption, drawing the water vapor into and/or beneath the organism/object's surface. By contrast, desiccants also attract ambient moisture, but adsorb—not absorb—it, by condensing the water vapor onto the surface, as a layer of film. When used as a food additive, a humectant has the effect of keeping the foodstuff moist. Humectants are sometimes used as a component of antistatic coatings for plastics. In pharmaceuticals and cosmetics, humectants can be used in topical dosage forms to increase the solubility of a chemical compound's active ingredient, increasing the active ingredients' ability to penetrate skin, and/or its activity time. This hydrating property can also be needed to counteract a dehydrating active ingredient.
