What Is Hygroscopy
Introduction to Hygroscopy
Hygroscopy is a critical property of materials that affects various industries, including pharmaceuticals, food storage, and manufacturing. Understanding hygroscopic materials is essential for ensuring product quality and longevity.
Hygroscopic Materials
Hygroscopic materials have the inherent ability to attract and hold water molecules from the surrounding environment. Common examples include:
- Salt: Used in food preservation.
- Silica Gel: Utilized as a desiccant in packaging.
- Glycerin: Employed in pharmaceuticals and cosmetics.
- Cellulose: Found in paper products.
