What Is 2-(2-Aminoethoxy)Ethanol?
2-(2-Aminoethoxy)Ethanol, also known as diglycolamine, is a small water-soluble molecule made up of two ethanol segments linked to an amino group. It is synthesized in a lab by reacting ethylene oxide with ammonia in carefully controlled conditions that keep impurities low so the final material meets cosmetic-grade standards. The ingredient does not come from botanical or animal sources, which makes its supply consistent and vegan friendly.
Chemists first explored this compound in industrial applications where its ability to grab on to carbon dioxide and other gases was useful. Over time formulators noticed that the same chemical “grip” could help hold hair styles in place. By the late 20th century it began appearing in styling mousses, gels and setting lotions, providing a lighter alternative to traditional stiff polymers.
Today you will most often find 2-(2-Aminoethoxy)Ethanol in leave-in hair sprays, volumizing mousses, wave setters and certain cream-based styling products aimed at flexible hold. It can also show up in hybrid treatment-styling formulas where brands want conditioning plus gentle fixation.
2-(2-Aminoethoxy)Ethanol’s Cosmetic Benefits/Uses
When added to a hair product this ingredient plays one key role that enhances performance:
- Hair fixing – It helps form temporary bonds along the hair shaft so strands stay arranged as styled. This delivers hold, boosts shape retention and fights frizz without making hair feel crunchy. Because the molecule is small and water compatible it rinses out easily, allowing users to restyle or cleanse without buildup.
Who Can Use 2-(2-Aminoethoxy)Ethanol
This hair-fixing agent is generally considered suitable for all scalp and hair types including oily, dry and combination. Its small size and water solubility mean it does not leave an occlusive film that could weigh down fine hair or block follicles. People with very sensitive or already irritated scalps may want to be cautious since any amine-based ingredient can be a mild irritant if overused or left on for long periods.
Because the compound is synthetically produced without animal-derived substances it is appropriate for vegans and vegetarians. Manufacturing does not rely on animal testing in most regions where modern safety data are accepted, though shoppers can verify a brand’s cruelty-free status if that is important to them.
No specific warnings exist for use by pregnant or breastfeeding individuals. Current safety assessments have not linked topical 2-(2-Aminoethoxy)ethanol to developmental or hormonal issues. Still this is not medical advice and anyone who is expecting or nursing should run new hair products past a qualified healthcare provider to be on the safe side.
The ingredient is not known to cause photosensitivity, so it does not make hair or scalp more vulnerable to sun damage. It also does not interfere with common color treatments or smoothing services when used at normal levels.
Potential Side Effects/Adverse Reactions
Reactions to 2-(2-Aminoethoxy)ethanol can vary from person to person. The points below list potential side effects, though they are uncommon when the ingredient is formulated and used correctly.
- Mild scalp irritation – a tingling or slight burning sensation, typically if the product is left on longer than instructed
- Contact dermatitis – redness, itching or small bumps in individuals with an existing sensitivity to amine compounds
- Dryness or tight feeling – especially on very dry or compromised scalps if the formula lacks balancing conditioners
- Eye irritation – stinging or watering if styling sprays or mousses accidentally get into the eyes
- Allergic reaction – extremely rare swelling or hives requiring prompt medical attention
If any of these effects occur discontinue use immediately and seek advice from a healthcare professional.
Comedogenic Rating
Rating: 0 (non-comedogenic). 2-(2-Aminoethoxy)Ethanol is a small, highly water-soluble molecule that rinses away without leaving an oily or occlusive film on skin or scalp. Because it does not sit in pores or create a greasy layer it has virtually no tendency to trigger blackheads or clogged pores. For this reason it is generally considered suitable for people who are prone to acne or breakouts.
Unlike many traditional styling resins it lacks fatty acids, waxes or heavy polymers that often raise comedogenic scores, further supporting its very low rating.
Summary
2-(2-Aminoethoxy)Ethanol is used in cosmetics mainly for hair fixing. Its small amine-based structure forms temporary bonds along the hair shaft, giving hold and shape retention while remaining flexible and easy to wash out. This balance of grip and lightness makes it a handy tool for formulators who want touchable styles without stiffness.
Although not a headline ingredient in mainstream beauty marketing, it has found a steady niche in leave-in sprays, mousses and hybrid treatment-styling products where gentle fixation is preferred over hard set gels.
Safety reviews show a low irritation profile when used at normal cosmetic levels, with serious reactions very rare. As with any new product it is wise to perform a quick patch test to confirm personal tolerance before full application.
