Ingredient review
Lauroyl Collagen Amino Acids
INCI: SODIUM/TEA-LAUROYL COLLAGEN AMINO ACIDS
A gentle, amino-acid-based surfactant that cleanses effectively while being kind to sensitive skin.
In plain English
This ingredient is a mild soap-like molecule made by combining lauric acid (from coconut or palm oil) with collagen amino acids (from animal sources). It helps water mix with oil and dirt so they can be rinsed away, but it's much less harsh than traditional soaps or sulfates. Your skin feels clean but not tight or dry after using it.

Quick decision guide
Useful, but context matters
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 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
A semi-synthetic surfactant created by reacting lauric acid with collagen-derived amino acids, then neutralizing with sodium or TEA (triethanolamine) salts. It belongs to the family of acyl amino acid surfactants, known for their mildness and compatibility with sensitive skin.
How it works
In a cleanser, this molecule has a water-loving head (the amino acid part) and an oil-loving tail (the lauric acid part). When you lather up, the tails grab onto sebum, makeup, and dirt, while the heads stay in the water. Rinsing washes everything away. Because the head is large and gentle, it doesn't disrupt the skin's protective barrier as much as harsher surfactants.
Pros
Very gentle on skin
The large amino acid head group makes this surfactant much less irritating than sulfates or soaps, so it's ideal for sensitive or reactive skin.
Leaves skin feeling soft
Unlike harsh cleansers that strip natural oils, this ingredient helps maintain the skin's moisture barrier, so your face feels comfortable after washing.
Cons and cautions
Not vegan-friendly
The collagen amino acids are typically sourced from animal hides or bones, so this ingredient is not suitable for strict vegan or cruelty-free routines.
Lower foam volume
If you love a big, bubbly lather, this surfactant produces a creamier, less voluminous foam, which some users find less satisfying.
Best for
- People with dry or sensitive skin
- Those who prefer sulfate-free cleansers
- Anyone looking for a gentle daily face wash
Use caution if
- Strict vegans (animal-derived collagen)
- Those allergic to coconut-derived fatty acids
Usage tips
Safety summary
Considered safe for use in rinse-off cosmetics at typical concentrations. Very low irritation and sensitization potential. Not recommended for leave-on products at high concentrations due to potential mild drying over time.
Research notes
Acyl amino acid surfactants, including lauroyl collagen amino acids, have been studied for their mildness and low skin irritation. They are well-tolerated in clinical patch tests and are commonly recommended for sensitive skin. However, specific long-term studies on this exact compound are limited.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and most major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Facial cleansers, Body washes, Shampoos, Makeup removers
- Environmental note
- While biodegradable, the sourcing of lauric acid from palm oil may raise sustainability concerns. Look for RSPO-certified palm oil or coconut-derived alternatives.
Good to know
- This ingredient is often listed near the top of an ingredient list in mild cleansers.
- It is biodegradable and considered environmentally friendlier than some synthetic surfactants.
