Ingredient review
Ethanolamine Glycerophosphate
INCI: ETHANOLAMINE GLYCEROPHOSPHATE
A gentle synthetic humectant that helps hydrate skin and support barrier function, but research on its long-term benefits is still limited.
In plain English
Ethanolamine glycerophosphate is a lab-made ingredient that attracts water to the skin, helping it stay hydrated. It also has a mild conditioning effect, which can make the skin feel smoother. Think of it as a helper molecule that supports your skin's natural moisture balance without being heavy or greasy.

Quick decision guide
Useful, but context matters
Ethanolamine Glycerophosphate is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Ethanolamine Glycerophosphate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
Ethanolamine glycerophosphate is a synthetic compound combining ethanolamine (a small organic molecule) with glycerophosphate (a phosphate ester of glycerol). It is produced in a lab and used in skincare as a humectant and skin-conditioning agent.
How it works
In a cosmetic product, ethanolamine glycerophosphate works by attracting water molecules from the environment or deeper layers of the skin to the outer layer (the stratum corneum, which is the skin's outermost protective barrier). This helps increase moisture content and temporarily plump the skin. It may also interact with the skin's natural moisturizing factors to support barrier integrity.
Pros
Gentle hydration
Ethanolamine glycerophosphate provides moisture without the tacky or heavy feel some humectants can leave, making it comfortable for daily use.
Low irritation risk
It has a low irritation profile, so it's unlikely to cause stinging or redness, even for those with reactive skin.
Cons and cautions
Limited research
Compared to classic humectants like glycerin, there is less published research on ethanolamine glycerophosphate's long-term benefits and efficacy.
Climate-dependent effectiveness
Like many humectants, it draws moisture from the air; in very dry environments, it may pull water from deeper skin layers instead, potentially leading to dryness over time.
Best for
- People with normal to dry skin looking for a lightweight hydrating ingredient
- Those with sensitive skin who want a low-irritation humectant
Use caution if
- Individuals seeking a proven, well-researched humectant may prefer more established options like glycerin
Usage tips
Safety summary
Ethanolamine glycerophosphate is considered safe for topical use in cosmetics. It has low irritation and comedogenic potential, making it suitable for most skin types. However, long-term safety data is limited, so it is best used as part of a balanced formulation.
Research notes
Research on ethanolamine glycerophosphate is sparse. Most evidence comes from formulation studies and ingredient safety assessments rather than large-scale clinical trials. It is generally regarded as a safe humectant, but its efficacy compared to more established ingredients is not well-documented.
Common label clues
- Typical concentration
- Typically used at 0.5% to 2% in leave-on products
- Regulatory status
- Generally recognized as safe for use in cosmetics at typical concentrations. No specific restrictions by major regulators like the FDA or EU CosIng, but always check product-specific formulations.
- Common uses
- Moisturizers, Serums, Toners, Eye creams
- Environmental note
- As a synthetic compound, its environmental impact depends on manufacturing processes. It is not known to be bioaccumulative or toxic to aquatic life at typical cosmetic use levels.
Good to know
- Ethanolamine glycerophosphate is often used in combination with other humectants for a multi-faceted hydration approach.
- It is not a common ingredient in drugstore products; you are more likely to find it in specialty or indie skincare lines.
