What Is Dihydroxyethyl Oleyl Glycinate?

Dihydroxyethyl Oleyl Glycinate is a specialty ingredient created by joining parts of oleyl alcohol, a fatty substance that comes from natural oils like olive or rapeseed, with glycine, the simplest amino acid. The result is a molecule that holds both water-loving and oil-loving sections, letting it mix smoothly into many beauty formulas. Chemists first explored it in the late twentieth century when the cosmetic industry was searching for gentler cleansing agents that could also soften hair and skin. Production involves reacting oleyl alcohol with ethylene oxide to introduce two hydroxyethyl groups, then adding glycine to form an inner salt that balances charge and boosts mildness. Today you can spot it in rinsable products such as facial cleansers, body washes, shampoos, bubble baths and micellar waters as well as in leave-on items like conditioning sprays, anti-frizz serums and lightweight lotions.

Dihydroxyethyl Oleyl Glycinate’s Cosmetic Benefits/Uses

Formulators choose this multitasker for several helpful reasons:

  • Antistatic: It reduces static buildup so hair looks smoother and is easier to style without flyaways.
  • Hair conditioning: Its fatty chain coats hair strands, adding softness and a light slip that helps with detangling.
  • Cleansing: The ingredient lifts away dirt and excess oil while feeling mild on skin and scalp, making it suited for daily use.
  • Foam boosting: It enhances the thickness and stability of lather in shampoos and washes, giving users that rich creamy foam many enjoy.

Who Can Use Dihydroxyethyl Oleyl Glycinate

This amphiphilic molecule is gentle enough for nearly all skin and hair types. Dry, sensitive and mature skin tends to appreciate its fatty backbone that helps reduce tightness while oily or acne-prone skin benefits from its light cleansing action that does not clog pores. Only those extremely prone to build-up might want to limit leave-on products containing high amounts of the ingredient.

Dihydroxyethyl Oleyl Glycinate is usually produced from plant-derived oleyl alcohol and synthetic glycine so formulations made with it are typically suitable for vegans and vegetarians. If strict animal-free certification is important, check the final product for third-party verification because processing aids can vary by supplier.

Current safety assessments show no special risks for women who are pregnant or breastfeeding since the compound stays on the skin surface and is not known to penetrate deeply. That said this is not medical advice and anyone expecting or nursing should have a doctor review any personal care routine to be safe.

The ingredient does not cause photosensitivity, making it fine for daytime use without increasing sun sensitivity. It is also color-safe and gentle on chemically treated hair.

Potential Side Effects/Adverse Reactions

Side effects from topical use of Dihydroxyethyl Oleyl Glycinate differ from person to person. The issues listed below are only potential outcomes and are unlikely when the ingredient is used at normal levels in well-formulated products.

  • Skin irritation
  • Allergic contact dermatitis
  • Eye irritation
  • Product build-up on very fine hair

If you experience any of these reactions stop using the product and consult a healthcare professional.

Comedogenic Rating

Rating: 1 / 5

Dihydroxyethyl Oleyl Glycinate carries a long fatty tail that could, in theory, linger on skin, yet its structure also features two hydroxyethyl groups and an inner salt that keep the molecule water friendly. In rinse-off cleansers the ingredient quickly disperses and is washed away, leaving little chance to block pores. Even in leave-on sprays or light lotions the usage level is typically low so any occlusive film is minimal.

Because of this low tendency to clog pores, the ingredient is generally fine for people prone to acne or breakouts.

Formulators sometimes pair it with heavier oils or butters that may raise the finished product’s overall comedogenicity, so always look at the entire ingredient list if you are highly breakout sensitive.

Summary

Dihydroxyethyl Oleyl Glycinate acts as a gentle cleanser, foam booster, antistatic agent and light conditioner. Its amphiphilic design lifts dirt and oil while the oleyl chain smooths hair cuticles and softens skin, and its zwitterionic nature improves lather stability without harshness.

The ingredient sits in the middle tier of popularity: common enough in sulfate-free shampoos, facial washes and micellar waters but not as widespread as older surfactants like cocamidopropyl betaine. Brands seeking mildness with conditioning benefits tend to choose it.

Current data show it is safe for almost all users with a very low risk of irritation or sensitization. As with any new cosmetic, it is wise to patch test a product that contains Dihydroxyethyl Oleyl Glycinate before full use just to be sure your skin agrees with the formula.
