Ingredient review
Sodium Lauroyl Collagen Amino Acids
INCI: Sodium Lauroyl Collagen Amino Acids
A mild, amino-acid-based cleanser that effectively removes dirt and oil without stripping the skin's natural moisture barrier.
In plain English
This is a gentle cleansing ingredient made by combining lauric acid (from coconut or palm oil) with amino acids from collagen. It creates a mild lather that lifts away dirt, oil, and makeup without leaving skin feeling tight or dry. Unlike harsh soaps, it respects the skin's natural pH and is less likely to cause irritation.

Quick decision guide
Easy yes for most routines
Sodium 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 Sodium 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 (a fatty acid from coconut or palm oil) with amino acids derived from collagen. 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, it reduces the surface tension of water, allowing it to mix with oils and dirt on the skin. The lauroyl group attaches to oil, while the amino acid portion is water-soluble, so rinsing washes away the trapped impurities. Its large molecular size means it stays on the skin's surface and doesn't penetrate deeply, reducing irritation risk.
Pros
Extremely gentle
Its large molecular structure and pH-friendly nature make it one of the mildest surfactants, ideal for compromised or reactive skin.
Non-stripping
Unlike sodium lauryl sulfate, it cleans without removing the skin's natural oils, helping maintain a healthy moisture barrier.
Cons and cautions
Animal-derived source
Collagen amino acids are typically sourced from animal by-products, which may not suit vegans or those preferring plant-based ingredients.
Moderate lather
It produces a creamy, low foam rather than a big bubbly lather, which some users may 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
- Vegans or those avoiding animal-derived ingredients (check source)
- People with known collagen allergies (rare)
Usage tips
Safety summary
Considered safe for use in cosmetics at typical concentrations. Low irritation and sensitization potential. Rare allergic reactions possible in individuals with collagen sensitivity.
Research notes
Amino acid surfactants like sodium lauroyl collagen amino acids are well-studied for mildness and skin compatibility. Clinical and dermatological reviews support their use in sensitive-skin formulations.
Common label clues
- Typical concentration
- 5–15% in rinse-off cleansers
- Regulatory status
- Approved for use in cosmetics globally, including by the EU CosIng database and US FDA (as part of cosmetic ingredients). No specific restrictions.
- Common uses
- Facial cleansers, Body washes, Shampoos, Makeup removers
- Environmental note
- Biodegradable and generally considered low in aquatic toxicity, but sourcing of lauric acid from palm oil may raise sustainability concerns.
Good to know
- Often found in 'sulfate-free' and 'gentle' cleanser formulations.
- It is biodegradable and considered environmentally friendlier than some traditional surfactants.
