Capryloyl Sarcosine
INCI: Capryloyl Sarcosine
A mild, amino-acid-based surfactant that cleanses effectively while respecting the skin barrier.
In plain English
Capryloyl sarcosine is a gentle cleansing ingredient made by combining a fatty acid from coconut oil with sarcosine, an amino acid naturally found in the body. It helps remove dirt, oil, and makeup without stripping the skin's natural moisture barrier, making it a popular choice for sensitive or dry skin types.

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 Capryloyl Sarcosine.
- 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
Capryloyl sarcosine is a semi-synthetic surfactant derived from coconut fatty acids and the amino acid sarcosine. It belongs to the family of acyl sarcosinates, known for their mildness and compatibility with the skin.
How it works
In a cosmetic product, capryloyl sarcosine works by reducing the surface tension between water and oil, allowing impurities to be lifted away and rinsed off. Unlike harsher sulfates, it has a larger molecular structure that is less likely to penetrate and irritate the skin barrier, while still providing effective cleansing and a soft, non-stripping feel.
Pros
Very gentle on skin
Its large molecular structure means it cleanses without penetrating or damaging the skin barrier, reducing the risk of irritation and dryness.
Maintains moisture balance
Unlike harsh sulfates, capryloyl sarcosine does not strip the skin of its natural oils, helping to keep the skin comfortable and hydrated after washing.
Cons and cautions
Less effective on heavy makeup
As a very mild surfactant, it may struggle to remove long-wear or waterproof makeup on its own, often requiring a double-cleansing routine.
Higher cost
Amino-acid-based surfactants like capryloyl sarcosine are generally more expensive to produce than conventional sulfates, which can increase product prices.
Best for
- People with sensitive or reactive skin
- Those with dry or dehydrated skin looking for a non-stripping cleanser
- Anyone seeking a sulfate-free cleansing option
Use caution if
- Individuals with a known allergy to coconut-derived ingredients (rare)
Usage tips
Safety summary
Capryloyl sarcosine is considered safe for use in cosmetics at typical concentrations. It has a low irritation and sensitization potential, supported by safety assessments from cosmetic ingredient review panels.
Research notes
Studies and safety reviews indicate that acyl sarcosinates, including capryloyl sarcosine, are mild surfactants with good skin compatibility. They are less damaging to the skin barrier than sodium lauryl sulfate and are well-tolerated in leave-on and rinse-off products.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. Generally recognized as safe when used as directed.
- Common uses
- Facial cleansers, Makeup removers, Shampoos, Body washes
- Environmental note
- Capryloyl sarcosine is biodegradable and has a lower aquatic toxicity profile compared to many conventional surfactants, making it a more eco-conscious choice.
Good to know
- Capryloyl sarcosine is often listed near the top of ingredient lists in sulfate-free cleansers because it acts as the primary cleansing agent.
- It is biodegradable and considered environmentally friendlier than some traditional surfactants.
