INCI: Capryl/Capramidopropyl Betaine
A gentle, coconut-derived surfactant that cleans effectively without stripping the skin, making it a popular choice for sensitive skin formulas.
In plain English
This ingredient is a mild cleansing agent made from coconut oil and amino acids. It helps remove dirt, oil, and makeup while creating a soft, creamy lather. Unlike harsher detergents, it is less likely to leave your skin feeling tight or dry, which is why it's often found in gentle, everyday cleansers and baby products.

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 Capryl/Capramidopropyl Betaine.
- 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
Capryl/Capramidopropyl Betaine is a semi-synthetic surfactant derived from coconut oil and betaine (a natural compound found in beets). It belongs to the betaine family of amphoteric surfactants, meaning it can work in both acidic and alkaline conditions, making it versatile in formulations.
How it works
In a cosmetic product, this ingredient reduces the surface tension between water and oil, allowing dirt and sebum to be rinsed away. It also helps stabilize foam and boosts the mildness of other cleansing agents, reducing overall irritation potential.
Pros
Mild on skin
Unlike sodium lauryl sulfate, this surfactant cleans without stripping the skin's moisture barrier, making it ideal for daily use.
Good foam quality
It produces a dense, creamy lather that feels pleasant and rinses easily, enhancing the user experience.
Cons and cautions
Limited cleansing power alone
On its own, it may not thoroughly remove heavy makeup or long-wearing sunscreen, so it's often paired with other cleansers.
Potential for mild irritation at high levels
While generally very gentle, concentrations above 15% can cause slight dryness or irritation in some individuals.
Best for
- People with sensitive or easily irritated skin
- Those looking for a sulfate-free, gentle cleanser
Use caution if
- Individuals with known coconut oil allergy (rare, but possible)
Usage tips
Safety summary
Capryl/Capramidopropyl Betaine is considered safe for use in cosmetics at typical concentrations. It has low irritation and sensitization potential, though individuals with coconut allergies should patch-test first.
Research notes
Research indicates that betaine-based surfactants are among the mildest cleansing agents available, with studies showing minimal disruption to skin barrier function compared to sulfates. However, most evidence comes from ingredient safety reviews rather than large-scale human trials.
Common label clues
- Typical concentration
- Typically 2–15% in rinse-off products
- Regulatory status
- Approved for use in cosmetics globally, including by the FDA (US) and EU CosIng database, with no known restrictions at typical use levels.
