These are added to cosmetics like oil in water type creams (vanishing cream) to prevent their drying out.
What is a humectant ingredient?
Humectants are ingredients found in lotions and cleansers that hydrate the skin by attracting water molecules like a magnet. Chemically speaking, humectants are hygroscopic substances that form hydrogen bonds with water molecules. This bonding helps moisturize the skin by drawing water from the lower cell layers.
What are the benefits of humectants?
Humectants can provide numerous benefits such as moisturization, exfoliation, potentiation of preservation activity, solvency to help dissolve actives, modification of skin feel, and helping to improve freeze/thaw stability of oil in water emulsions.
What does humectant mean?
