Ingredient review
TEA-Lauroyl Collagen Amino Acids
INCI: TEA-LAUROYL COLLAGEN AMINO ACIDS
A gentle, amino-acid-based surfactant that cleanses effectively without stripping the skin barrier.
In plain English
This ingredient is a mild soap-like molecule made from collagen amino acids (the building blocks of protein) and lauric acid (a fatty acid from coconut or palm oil). It helps water mix with oil and dirt so they can be rinsed away, but it's much gentler than traditional harsh soaps. Because it's derived from natural amino acids, it tends to respect the skin's natural pH and moisture balance, making it a popular choice for sensitive or dry skin cleansers.

Quick decision guide
Useful, but context matters
TEA-Lauroyl Collagen Amino Acids 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-Lauroyl Collagen Amino Acids.
- 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-Lauroyl Collagen Amino Acids is a surfactant created by reacting lauric acid with collagen-derived amino acids and then neutralizing with triethanolamine (TEA). It belongs to the family of acyl amino acid surfactants, known for their mildness and compatibility with skin.
How it works
In a cosmetic product, this ingredient reduces the surface tension between water and oil, allowing impurities and excess sebum to be emulsified and rinsed away. Its large molecular structure and amino acid backbone make it less penetrating and less disruptive to the skin's lipid barrier compared to sulfate-based cleansers.
Pros
Ultra-gentle on skin
Unlike sodium lauryl sulfate, this surfactant has a large, mild molecule that cleans without stripping the skin's natural oils, reducing tightness and irritation after washing.
pH-friendly
It works well at a skin-compatible pH (around 5.5), helping to preserve the acid mantle and support a healthy skin barrier.
Cons and cautions
Lower foam volume
It produces a creamy, low-lather foam rather than big bubbles, which may feel less satisfying to those accustomed to high-foam cleansers.
Potential TEA concerns
Triethanolamine (TEA) can form nitrosamines under certain conditions, though cosmetic-grade TEA is purified and used at safe levels. Regulatory bodies consider it safe in rinse-off products.
Best for
- People with dry or sensitive skin looking for a non-stripping cleanser
- Those who prefer sulfate-free, amino-acid-based cleansing formulas
Use caution if
- Individuals with a known allergy to coconut-derived fatty acids or TEA
Usage tips
Safety summary
TEA-Lauroyl Collagen Amino Acids is considered safe for use in rinse-off cosmetics at typical concentrations. It has low irritation and comedogenic potential. The TEA component is regulated to minimize nitrosamine contamination, and no significant health risks have been identified in normal cosmetic use.
Research notes
Amino acid surfactants are well-studied for their mildness and skin compatibility. While specific studies on TEA-Lauroyl Collagen Amino Acids are limited, the broader class of acyl amino acid surfactants is supported by dermatological research showing reduced barrier disruption compared to sulfates. Regulatory bodies like the Cosmetic Ingredient Review (CIR) have reviewed TEA and found it safe in rinse-off products at current usage levels.
Common label clues
- Typical concentration
- 1–10% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics by the FDA (as part of generally recognized safe surfactants) and by the EU CosIng database. TEA levels are restricted to ≤5% in finished products to limit nitrosamine formation.
- Common uses
- Facial cleansers, Body washes, Shampoos, Gentle makeup removers
- Environmental note
- Amino acid-based surfactants are generally biodegradable and considered more environmentally friendly than many petroleum-based surfactants. However, sourcing of lauric acid from palm oil may raise sustainability concerns unless certified sustainable.
Good to know
- Collagen amino acids are not the same as intact collagen; they are smaller protein fragments that do not rebuild skin collagen but do contribute to mildness.
- This ingredient is often listed near the middle or end of an ingredient list because effective cleansing requires only a small amount.
