    Product Description

    Hydroxyethyl Urea, CAS 2078-71-9, commonly abbreviated HEU, is a nonionic humectant based on a urea structure modified with a hydroxyethyl group; the EC/EINECS number is 640-848-4.

    Synonyms: N-(2-Hydroxyethyl)urea; 2-Hydroxyethylurea; 1-(2-Hydroxyethyl)urea; Mono(2-hydroxyethyl)urea.

    CAS: 2078-71-9.

    Molecular formula: C₃H₈N₂O₂.

    Molecular weight: 104.11.

    EC number: 640-848-4.

    It is a white to almost white crystalline powder or granules with a melting point of about 164–169 °C.

    It is freely soluble in water and soluble in ethanol and other polar solvents; it is hygroscopic and readily absorbs moisture from air.

    A typical finished-product use level is about 2–10%, with a predicted density of about 1.22 g/cm³ and a pKa around 13.3.

    It is used as a humectant and skin-conditioning agent in moisturizers, serums, lotions, creams, shampoos, conditioners and bath products.

    It improves moisture retention, spreadability and skin feel with less tackiness than glycerin and is compatible with hyaluronic acid, betaine and common emulsifiers and surfactants.

    The solid grade is a crystalline powder, while the aqueous grade is supplied at a defined concentration such as about 50%; confirm the required form and concentration.

    Confirm assay or active content, appearance, aqueous-solution pH, color, heavy metals, residual urea, moisture and microbial limits.

    Store in tightly closed containers in a cool, dry, ventilated area protected from moisture; solid grade is best stored below about 25 °C, and aqueous solution at 5–30 °C away from freezing and excessive heat.

    Confirm the current product-specific specification.

    Confirm packaging with the requested quantity and destination requirements.

    Document requirements should be confirmed from the current specification, SDS, COA or other product-specific files.

    FAQ - Technical & Supply Chain

    • Q:

      What is Hydroxyethyl Urea CAS 2078-71-9?

      A: Hydroxyethyl Urea is a nonionic humectant and moisturizer based on a urea structure modified with a hydroxyethyl group. It has CAS 2078-71-9, molecular formula C₃H₈N₂O₂ and a molecular weight of 104.11 g/mol.
    • Q:

      What is Hydroxyethyl Urea used for in personal care?

      A: It is used in skin-care and hair-care formulations to increase moisture retention and improve skin feel. Typical applications include moisturizers, serums, lotions, shampoos, conditioners and other leave-on or rinse-off products.
    • Q:

      What is the difference between Hydroxyethyl Urea powder and aqueous solution?

      A: The solid grade is generally a crystalline powder with high assay, while the aqueous grade is supplied at a defined concentration such as about 50%. The solution is convenient for direct water-based formulation, but the solid offers more flexibility for custom concentrations and shipping.
    • Q:

      Which specifications should be checked for Hydroxyethyl Urea?

      A: Check assay or active content, appearance, pH in aqueous solution, color, heavy metals, residual urea and microbial limits. Because the material is hygroscopic, confirm moisture content and storage instructions from the supplier.
    • Q:

      How should Hydroxyethyl Urea be stored and handled?

      A: Keep Hydroxyethyl Urea in tightly closed containers in a cool, dry, ventilated area and protect it from moisture. It is water-soluble and hygroscopic, so standard solid-chemical handling, dust control and personal protective equipment should be used.
