Ingredient review
Di-TEA-Palmitoyl Aspartate
INCI: DI-TEA-PALMITOYL ASPARTATE
A mild synthetic surfactant that helps cleanse without stripping the skin, but it's not a standout ingredient on its own.
In plain English
Di-TEA-Palmitoyl Aspartate is a man-made ingredient that helps water and oil mix together, so it can gently lift dirt and oil from your skin or hair. It's often used in cleansers and shampoos to create a mild foam and leave a soft, non-stripped feeling. Think of it as a helper that makes your cleanser work better without being harsh.

Quick decision guide
Useful, but context matters
Di-TEA-Palmitoyl Aspartate 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 Di-TEA-Palmitoyl Aspartate.
- 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
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A synthetic compound made by combining aspartic acid (an amino acid) with palmitic acid (a fatty acid) and triethanolamine (TEA). It acts as a surfactant and emulsifier.
How it works
It reduces the surface tension between water and oil, allowing them to blend. This helps lift sebum, dirt, and makeup from the skin so they can be rinsed away. Its mild nature means it cleanses without over-drying or irritating the skin barrier.
Pros
Mild on skin
Unlike harsher sulfates, this surfactant cleanses without stripping the skin's natural moisture barrier, making it suitable for daily use.
Good for sensitive formulas
It helps create stable, creamy textures in cleansers and conditioners, improving the overall feel and performance of the product.
Cons and cautions
Potential TEA sensitivity
Triethanolamine can cause mild irritation or allergic reactions in some people, especially those with very sensitive or compromised skin.
Not a star ingredient
It's a functional helper rather than a hero ingredient, so it won't provide noticeable skin benefits beyond cleansing.
Best for
- People with normal to dry skin who want a gentle daily cleanser
- Those looking for sulfate-free cleansing options
Use caution if
- Individuals with known sensitivity to triethanolamine or fatty acid derivatives
Usage tips
Safety summary
Generally considered safe for use in rinse-off cosmetics at typical concentrations. The main caution is for individuals with TEA sensitivity. Regulatory bodies limit TEA levels to prevent nitrosamine formation.
Research notes
Research on Di-TEA-Palmitoyl Aspartate specifically is limited, but its components (aspartic acid, palmitic acid, TEA) are well-studied and deemed safe in cosmetic use by expert panels like the Cosmetic Ingredient Review (CIR).
Common label clues
- Typical concentration
- Usually 0.5–5% in rinse-off products
- Regulatory status
- Approved for use in cosmetics by the FDA and EU CosIng, with concentration limits on TEA content to ensure safety.
- Common uses
- Facial cleansers, Body washes, Shampoos, Conditioners
- Environmental note
- Synthetic surfactants may have moderate biodegradability; look for eco-friendly formulations if this is a concern.
Good to know
- This ingredient is often part of a larger surfactant blend, so its effects are best judged within the full formula.
- TEA can form nitrosamines under certain conditions, but cosmetic-grade TEA is purified to minimize this risk.
