Ingredient review
TEA-Lauryl Aspartate
INCI: TEA-Lauryl Aspartate
A gentle, amino-acid-based surfactant that cleanses effectively while being kind to sensitive skin.
In plain English
TEA-Lauryl Aspartate is a mild cleansing ingredient made from lauric acid (found in coconut oil) and aspartic acid (an amino acid). It helps lift dirt, oil, and makeup from your skin so they can be rinsed away with water. Unlike harsher soaps, it cleans without stripping your skin's natural moisture barrier, making it a popular choice for gentle or sensitive-skin formulas.

Quick decision guide
Useful, but context matters
TEA-Lauryl 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 TEA-Lauryl 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
TEA-Lauryl Aspartate is a surfactant, meaning it reduces the surface tension between water and oil, allowing them to mix and be rinsed away. It is created by combining lauric acid (a fatty acid from coconut or palm oil) with aspartic acid (an amino acid) and neutralizing with triethanolamine (TEA). The result is a mild, water-soluble cleansing agent.
How it works
In a cleanser, TEA-Lauryl Aspartate surrounds oil and dirt particles, breaking them into tiny droplets that can be easily washed off with water. Because it is an amino-acid-based surfactant, it has a pH close to that of healthy skin (around 5.5), so it cleans without disrupting the skin's acid mantle or causing tightness or irritation.
Pros
Mild on skin
Unlike sodium lauryl sulfate, TEA-Lauryl Aspartate cleans without causing tightness or irritation, making it ideal for daily use on sensitive or dry skin.
pH-friendly
This surfactant has a pH close to skin's natural level, so it helps preserve the acid mantle that protects against bacteria and moisture loss.
Cons and cautions
Potential palm oil sourcing
Lauric acid is often derived from palm or coconut oil. If not sustainably sourced, palm oil production can contribute to deforestation.
Contains triethanolamine
TEA is used to neutralize the surfactant. While safe at low levels, some people prefer to avoid TEA due to potential irritation in high concentrations.
Best for
- People with dry or sensitive skin looking for a non-stripping cleanser
- Anyone who prefers amino-acid-based, mild surfactants over sulfates
Use caution if
- Those with a known allergy to coconut-derived ingredients (rare)
Usage tips
Safety summary
TEA-Lauryl Aspartate is considered safe for use in rinse-off cosmetics at typical concentrations. The small amount of triethanolamine present is well within safety limits. It is non-irritating and non-comedogenic for most skin types.
Research notes
Amino-acid-based surfactants like TEA-Lauryl Aspartate are well-studied for their mildness and low irritation potential compared to traditional anionic surfactants. The Cosmetic Ingredient Review has reviewed TEA salts and found them safe in rinse-off products. No significant new safety concerns have emerged in recent literature.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. The Cosmetic Ingredient Review (CIR) panel has deemed TEA salts safe in rinse-off products at concentrations up to 5%.
- Common uses
- Facial cleansers, Body washes, Shampoos, Makeup removers
- Environmental note
- Lauric acid is typically sourced from coconut or palm oil. Look for products with RSPO-certified palm oil or coconut-derived alternatives for a more sustainable choice.
Good to know
- TEA-Lauryl Aspartate is often found in sulfate-free cleansers labeled 'gentle' or 'for sensitive skin.'
- It is biodegradable and considered environmentally friendlier than some traditional surfactants.
