What Is Hydroxyethyl Urea?
Hydroxyethyl Urea is a synthetic version of urea that has been modified with a hydroxyethyl group to improve its compatibility with skin and hair care formulas. Chemically it belongs to the family of humectants, ingredients that attract water. While natural urea occurs in the skin’s own moisturizing system, the cosmetic grade of Hydroxyethyl Urea is produced in a lab through the reaction of urea with ethylene carbonate, creating a stable water-soluble powder or liquid.
The ingredient began appearing in cosmetic research in the late 1990s as brands looked for alternatives to glycerin that would deliver strong hydration without a sticky feel. Its gentle profile and ease of formulation quickly made it popular in leave-on products. Today you will spot Hydroxyethyl Urea in face and body moisturizers, hydrating serums, sheet masks, anti-aging creams, hand lotions, hair masks and conditioning sprays.
Hydroxyethyl Urea’s Cosmetic Benefits/Uses
Hydroxyethyl Urea brings several helpful actions to a formula
- Hair Conditioning: Helps soften and smooth hair strands so they feel silkier and are easier to comb through
- Humectant: Draws moisture from the environment and binds it to the skin or hair surface, supporting lasting hydration and reducing dryness
- Skin Conditioning: Enhances the skin’s texture by keeping it supple and comfortable, which can make fine lines look less noticeable and improve overall feel
Who Can Use Hydroxyethyl Urea
Because Hydroxyethyl Urea is a lightweight humectant that does not clog pores it is generally suitable for dry, normal, combination and oily skin types, including many people with sensitive skin who find glycerin sticky or irritating. It has a neutral pH and low potential for allergy so most hair types can also tolerate it well.
The ingredient is produced entirely in a laboratory from non-animal sources, making it compatible with vegan and vegetarian lifestyles.
Pregnant or breastfeeding individuals are not known to face any added risk from topical use of Hydroxyethyl Urea, yet this is not medical advice and those expecting or nursing should run all skincare choices past their doctor to be safe.
Hydroxyethyl Urea does not increase photosensitivity so it can be used day or night without special sun precautions beyond daily sunscreen that dermatologists already recommend.
Potential Side Effects/Adverse Reactions
Side effects and reactions to topical Hydroxyethyl Urea can vary from person to person. The points below list potential issues but they are uncommon when the ingredient is formulated and used correctly.
- Mild redness or warmth shortly after application
- Transient stinging on very compromised or cracked skin
- Allergic contact dermatitis in rare cases
- Eye irritation if the product accidentally gets into the eyes
If any of these effects occur discontinue use and seek medical advice if symptoms persist or worsen.
Comedogenic Rating
Rating: 0/5
Hydroxyethyl Urea is water soluble and lightweight so it does not create an occlusive film that can trap oil or debris in pores. It also lacks fatty acids or heavy oils that typically raise a comedogenic score. Because of this profile it is considered non-comedogenic and is generally well suited for people who are prone to acne or breakouts. No data suggest it triggers or worsens blackheads or whiteheads even with long-term use.
Formulators often pair Hydroxyethyl Urea with acne treatments like salicylic acid or benzoyl peroxide precisely because it hydrates without congestion, a helpful extra detail for anyone comparing ingredient lists.
Summary
Hydroxyethyl Urea is mainly valued as a humectant and skin or hair conditioner. It pulls water into the upper layers of skin and along the hair shaft, boosting softness and flexibility. Because it is non-sticky and compatible with a wide pH range it slips easily into creams, serums, masks and leave-in hair products, where it can improve texture and help other actives spread more evenly.
While not as famous as glycerin or hyaluronic acid it has quietly become a staple in many modern formulas thanks to its smooth feel and reliable performance. You will spot it most in mid to high tier moisturizers and hair treatments that market a lightweight finish.
Safety data show a very low risk of irritation or allergy for most users. Still, everyone’s skin is unique so it is wise to patch test any new product that contains Hydroxyethyl Urea to confirm personal compatibility before full use.
