Sodium Cocoyl Collagen Amino Acids
INCI: SODIUM COCOYL COLLAGEN AMINO ACIDS
A mild, coconut-derived surfactant that cleanses effectively while being gentle on the skin barrier.
In plain English
Sodium Cocoyl Collagen Amino Acids is a gentle cleansing ingredient made by combining fatty acids from coconut oil with amino acids from collagen. It helps remove dirt, oil, and makeup without stripping the skin of its natural moisture, making it a popular choice for sensitive or dry skin types.

Quick decision guide
Useful, but context matters
Sodium Cocoyl 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 Cocoyl 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 surfactant (cleansing agent) created by reacting coconut oil fatty acids with collagen-derived amino acids. It belongs to the class of amino acid-based surfactants known for their mildness.
How it works
It works by reducing the surface tension of water, allowing oils and dirt to be lifted away from the skin and rinsed off. Unlike harsher sulfates, it has a larger molecular structure that is less likely to penetrate the skin barrier, resulting in a gentler cleanse.
Pros
Gentle on skin
Its large molecular structure makes it less likely to penetrate and irritate the skin, reducing the risk of dryness or tightness after washing.
Eco-friendly profile
Made from renewable coconut oil and collagen amino acids, it is biodegradable and considered more environmentally friendly than many petroleum-based surfactants.
Cons and cautions
Lower foam volume
Produces a creamier, less bubbly lather compared to sulfates, which may not appeal to those who prefer a foamy wash experience.
Higher cost
Amino acid surfactants are generally more expensive to produce, which can increase the price of finished products.
Best for
- People with dry or sensitive skin looking for a non-stripping cleanser
- Those who prefer sulfate-free or amino acid-based cleansing products
Use caution if
- Individuals with a known allergy to coconut-derived ingredients (rare)
Usage tips
Safety summary
Sodium Cocoyl Collagen Amino Acids is considered safe for use in cosmetics at typical concentrations. It has a low irritation and comedogenic risk, making it suitable for most skin types, including sensitive skin.
Research notes
Amino acid-based surfactants like this one are well-documented in cosmetic science for their mildness and skin compatibility. While specific studies on this exact ingredient are limited, the broader class is supported by dermatological research as a gentle alternative to traditional sulfates.
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. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Facial cleansers, Body washes, Shampoos, Makeup removers
- Environmental note
- Derived from coconut oil (a renewable resource) and collagen amino acids (often a byproduct of the leather industry), it is biodegradable and considered relatively eco-friendly.
Good to know
- This ingredient is often labeled as part of 'amino acid surfactants' in sulfate-free formulations.
- It is not the same as pure collagen; the collagen amino acids are used as building blocks for the surfactant molecule.
