Sodium Cornamphopropionate
INCI: SODIUM CORNAMPHOPROPIONATE
A gentle, coconut-derived surfactant that effectively cleanses while being kinder to sensitive skin than traditional sulfates.
In plain English
Sodium Cornamphopropionate is a mild cleansing ingredient made from coconut oil. It helps remove dirt, oil, and makeup from your skin and hair without causing the tight, dry feeling that harsher cleansers can leave behind. Think of it as a gentle soap alternative that respects your skin's natural moisture barrier.

Quick decision guide
Useful, but context matters
Sodium Cornamphopropionate 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 Cornamphopropionate.
- 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
Sodium Cornamphopropionate is an amphoteric surfactant, meaning it can work in both acidic and alkaline formulas. It is derived from coconut oil (specifically from coconut fatty acids) and is often used as a secondary cleanser to reduce irritation from stronger primary surfactants.
How it works
It reduces the surface tension between water and oil, allowing impurities to be lifted away and rinsed off easily. Because it is amphoteric, it is less likely to disrupt the skin's protective barrier compared to anionic surfactants like sodium lauryl sulfate.
Pros
Very gentle on skin
Its amphoteric nature means it cleanses without stripping the skin's natural oils, making it ideal for daily use on sensitive or dry skin.
Improves formula mildness
When combined with stronger surfactants, it reduces overall irritation potential, creating a more comfortable cleansing experience.
Cons and cautions
Limited cleansing power alone
For very oily skin or heavy makeup, it may not be effective enough as the only surfactant and is usually paired with stronger cleansers.
Coconut-derived source
While rare, individuals with coconut allergies should check labels, as this ingredient is processed from coconut oil.
Best for
- People with dry or sensitive skin
- Those looking for a sulfate-free cleanser
- Parents choosing gentle baby washes
- Anyone with eczema-prone skin
Use caution if
- Individuals with a known coconut oil allergy (very rare)
Usage tips
Safety summary
Sodium Cornamphopropionate is considered safe for use in cosmetics at typical concentrations. It has a low irritation and sensitization profile, making it suitable for sensitive skin and baby care products. No significant safety concerns have been raised by regulatory bodies.
Research notes
Research supports the mildness of amphoteric surfactants like Sodium Cornamphopropionate. Studies show they cause less skin barrier disruption compared to anionic surfactants. However, most evidence comes from broader surfactant safety data rather than specific ingredient trials.
Common label clues
- Typical concentration
- 1–15% in rinse-off products
- Regulatory status
- Approved for use in cosmetics globally, including by the FDA (USA) and EU CosIng database, with no known restrictions at typical concentrations.
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby care products
- Environmental note
- Derived from renewable coconut oil and generally considered biodegradable, though processing may involve chemical modification.
Good to know
- Sodium Cornamphopropionate is often used in 'no-tears' baby shampoos because of its low eye irritation potential.
- It is biodegradable and considered environmentally friendlier than some traditional surfactants.
