Fugtgiver

Fugtgiver is a Danish term used to describe substances that provide moisture to skin, hair, or other surfaces. In cosmetics and personal care, fugtgivere are commonly referred to as humectants. They work by attracting and retaining water, helping to improve hydration and the feel of a product on the skin.

Most fugtgivere are hygroscopic, meaning they draw moisture from the surrounding air or from deeper layers of the skin. Their effectiveness depends on environmental humidity and the product formulation. In very dry conditions, high concentrations can sometimes create a temporary sensation of tightness unless the formulation also includes occlusives—substances that seal in moisture, such as petrolatum or oils.

Common fugtgivere include glycerin (glycerol), propylene glycol, butylene glycol, sorbitol, urea, sodium PCA, and hyaluronic acid. These ingredients are frequently used in creams, lotions, serums, and cleansers to enhance hydration. In many products, fugtgivere are combined with emollients and occlusives to provide both hydration and moisture retention.

Regulatory and labeling context: in Danish labeling and documentation, the function “fugtgiver” may be used to describe moisturizing ingredients. In international contexts, these substances appear under their INCI names (for example, glycerin or hyaluronic acid). They are widely regarded as safe for topical use when used within approved concentrations, though individual sensitivities or allergies can occur.
