Ingredient review
Sodium Cocoabutteramphoacetate
INCI: SODIUM COCOABUTTERAMPHOACETATE
A gentle, cocoa-butter-derived surfactant that cleanses effectively while being kind to sensitive skin.
In plain English
Sodium cocoabutteramphoacetate is a mild cleansing ingredient made from cocoa butter. It helps wash away dirt, oil, and makeup without stripping your skin of its natural moisture. Because it's amphoteric (meaning it works well with other cleansers and is gentle), it's often used in products for sensitive or dry skin. Think of it as a kinder alternative to harsher soaps.

Quick decision guide
Useful, but context matters
Sodium Cocoabutteramphoacetate 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 Cocoabutteramphoacetate.
- 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 modifying cocoa butter fatty acids with amino-acetate groups, resulting in a mild, amphoteric cleansing agent.
How it works
It reduces the surface tension of water, allowing oil and dirt to be lifted away from the skin and rinsed off. Its amphoteric nature means it stays gentle even at different pH levels, and it helps stabilize foam in cleansers.
Pros
Very gentle on skin
Its amphoteric structure makes it one of the mildest surfactants, reducing the risk of irritation and dryness even with frequent use.
Moisturizing feel
Because it's derived from cocoa butter, it leaves a subtle emollient feel on the skin, helping to prevent that tight, dry sensation after washing.
Cons and cautions
Limited heavy-duty cleansing
It may not fully remove heavy, waterproof makeup or long-wear sunscreen on its own, so you might need a double-cleansing step.
Less common in drugstore products
It's not as widely used as cocamidopropyl betaine, so you may need to seek out specialty or natural brands to find it.
Best for
- People with dry or sensitive skin
- Those looking for a sulfate-free cleanser
- Parents choosing gentle baby washes
Use caution if
- Individuals with known cocoa butter allergy (rare)
- Those seeking a very high-foam, stripping cleanser
Usage tips
Safety summary
Sodium cocoabutteramphoacetate is considered safe for use in cosmetics. It has a low irritation and sensitization profile, making it suitable for sensitive skin and baby care. No significant safety concerns have been raised by regulatory bodies.
Research notes
While not as extensively studied as some common surfactants, its safety is supported by its chemical similarity to other well-studied amphoacetates and its history of use in mild cleansers. Published data confirm low eye and skin irritation.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for cosmetic use in the EU, US, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby care products
- Environmental note
- Derived from cocoa butter, a byproduct of chocolate production, making it a renewable and relatively sustainable ingredient. It is also readily biodegradable.
Good to know
- Sodium cocoabutteramphoacetate is often found in 'no-tears' baby shampoos because of its low eye-sting potential.
- It is biodegradable and considered environmentally friendlier than some traditional surfactants.
