Disodium Capryloamphodiacetate
INCI: DISODIUM CAPRYLOAMPHODIACETATE
A gentle, low-irritation surfactant ideal for sensitive or dry skin types.
In plain English
Disodium capryloamphodiacetate is a mild cleansing ingredient made from coconut oil. It helps lift dirt and oil from your skin so they can be rinsed away, but it's much less harsh than traditional soaps or sulfates. Because it's so gentle, it's often used in products for sensitive skin, babies, or people who find other cleansers drying.

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 Disodium Capryloamphodiacetate.
- 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 derived from caprylic acid (a fatty acid found in coconut oil) and amino-acid-like compounds. It belongs to the amphoacetate family, known for being exceptionally mild.
How it works
It reduces the surface tension between water and oil, allowing water to mix with and rinse away sebum, makeup, and debris. Its amphoteric nature (it can act as either an acid or a base) makes it gentle on the skin's natural barrier while still being an effective cleanser.
Pros
Very gentle on skin
It has a low irritation potential, making it suitable for sensitive, reactive, or eczema-prone skin without causing stinging or redness.
Helps preserve moisture
Unlike harsher detergents, it doesn't strip away the skin's natural oils, so your face feels clean but not tight or dry after washing.
Cons and cautions
May need help with heavy makeup
On its own, it may not fully remove waterproof or long-wear makeup, so you might need a double-cleansing step.
Not a 'natural' ingredient
Although derived from coconut, it undergoes chemical processing, which may not appeal to those seeking 100% natural formulations.
Best for
- People with dry or sensitive skin
- Those who find sulfate cleansers too harsh
- Anyone looking for a gentle daily face wash
Use caution if
- Individuals with known coconut oil allergy (rare, but possible)
- Those who prefer completely natural, plant-only cleansers
Usage tips
Safety summary
Disodium capryloamphodiacetate is considered very safe for cosmetic use. It has a low irritation and sensitization profile, and no significant health concerns have been identified in decades of use. It is not known to be comedogenic.
Research notes
Research on amphoacetate surfactants confirms their mildness compared to sulfates. Studies show they cause less disruption to the skin barrier and are well-tolerated even in repeated-use tests. However, most evidence comes from formulation studies rather than large-scale clinical trials.
Common label clues
- Typical concentration
- 1–15% in rinse-off products
- Regulatory status
