Hydroxyethyl urea is primarily known for its moisturizing properties in skincare products. It provides hydration without a sticky feel, enhances skin elasticity, and helps replenish skin moisture. It is also compatible with a wide range of skincare ingredients and is gentle and non-irritating.

Hydroxyethyl urea offers a high cost-performance ratio. Compared to more expensive moisturizers, it can achieve similar effects at a lower formulation cost.

Hydroxyethyl urea is a highly effective humectant. However, changes in pH can reduce its stability and cause color changes. Specifically, β-hydroxyethyl urea is widely used in cosmetic moisturizing formulations for its excellent hydration performance.
