Capric/Lauric/Myristic/Oleic Amidopropyl Betaine
INCI: CAPRIC/LAURIC/MYRISTIC/OLEIC AMIDOPROPYL BETAINE
A gentle, coconut-derived surfactant that cleanses effectively without over-drying, making it a popular choice for sensitive skin formulations.
In plain English
This ingredient is a mild cleansing agent made from coconut oil fatty acids. It helps create a rich lather and removes dirt and oil from your skin and hair, but it's much less harsh than traditional soaps or sulfates. Think of it as a gentle scrubber that won't strip away your skin's natural moisture barrier.

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 Capric/Lauric/Myristic/Oleic Amidopropyl 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
A blend of amidopropyl betaines derived from capric, lauric, myristic, and oleic acids—all fatty acids found in coconut oil. It is a semi-synthetic surfactant, meaning it's chemically modified from natural sources to improve its cleansing and foaming properties.
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, giving cleansers a luxurious, creamy lather. Because it is amphoteric (can act as both an acid and a base), it is gentle on skin and compatible with other cleansing ingredients.
Pros
Gentle on skin
This surfactant has a low irritation risk, making it ideal for daily use on sensitive or easily irritated skin.
Sulfate-free lather
It produces a creamy foam without relying on harsh sulfates, so your skin feels clean but not stripped.
Cons and cautions
Not for heavy-duty cleansing
If you wear heavy makeup or waterproof sunscreen, you may need a stronger cleanser or a double-cleansing routine.
Potential for mild dryness at high levels
In formulas with very high concentrations, it can still cause slight dryness, though far less than traditional soaps.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Anyone seeking sulfate-free or mild cleansing products
Use caution if
- Those with known allergies to coconut-derived ingredients (rare)
Usage tips
Safety summary
This ingredient has a strong safety profile with low irritation and sensitization potential. It is widely used in personal care products and is considered safe at typical concentrations. Rare allergic reactions are possible, especially in individuals sensitive to coconut-derived ingredients.
Research notes
Amidopropyl betaines, including this blend, have been studied for their mildness and low eye irritation potential. They are well-documented in cosmetic science literature as gentle alternatives to sulfate surfactants. Most evidence comes from formulation studies and safety assessments rather than large-scale clinical trials.
Common label clues
- Typical concentration
- 2% to 15% in rinse-off products
- Regulatory status
- Approved for use in cosmetics worldwide, including by the U.S. FDA and EU CosIng database. No specific restrictions at typical use levels.
