hygroscopicisuus
Hygroscopicisuus refers to the tendency of a substance to attract and hold water molecules from the surrounding environment. This absorption of moisture can occur from the air as vapor or directly from liquid water. Hygroscopic materials are often used in applications where moisture control is important, such as desiccants in packaging or in the formulation of certain pharmaceuticals and cosmetics.
The degree of hygroscopicisuus varies greatly between substances. Some materials, like anhydrous salts such as calcium
The physical and chemical properties of a substance can be significantly altered by the absorption of water.
