A humectant is a substance known for its unique moisture-retaining properties. It is utilized to prevent drying and maintain optimal moisture levels in products and materials. Humectants do not have a specific taste or texture as they serve a functional purpose rather than being consumed directly. They can be naturally derived or synthetic, and common examples include glycerin, sorbitol, and propylene glycol. Humectants work by attracting and absorbing water vapor from the environment, effectively reducing evaporation and keeping substances hydrated. They are widely used in various industries, including cosmetics, food, and pharmaceuticals, to enhance stability, texture, and shelf life.
