Bis(2-Hydroxyethyl) Urea
What is Bis(2-Hydroxyethyl) Urea?
Bis(2-Hydroxyethyl) Urea is a water-soluble humectant derived from urea, featuring two hydroxyethyl groups attached to the urea molecule, which enhances its moisturizing properties and stability compared to plain urea. It functions by attracting and retaining moisture in the skin, improving hydration levels and supporting the skin's natural barrier function. Commonly used in skincare formulations at concentrations of 1-10%, it provides long-lasting hydration without the potential irritation associated with higher concentrations of urea.
