Ingredient review
Sodium Capryloamphohydroxypropylsulfonate
INCI: Sodium Capryloamphohydroxypropylsulfonate
A gentle, low-irritation surfactant that effectively cleanses without stripping the skin barrier.
In plain English
This is a mild cleansing ingredient often used in 'gentle' or 'sensitive skin' cleansers. It helps lift away dirt, oil, and makeup while being much less harsh than traditional sulfates like sodium lauryl sulfate. It belongs to a class of surfactants called amphoterics, which means it can work well with other cleansing ingredients and is less likely to cause dryness or irritation.

Quick decision guide
Useful, but context matters
Sodium Capryloamphohydroxypropylsulfonate 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 Capryloamphohydroxypropylsulfonate.
- 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 Capryloamphohydroxypropylsulfonate is a synthetic amphoteric surfactant derived from caprylic acid (a fatty acid found in coconut oil) and other chemical building blocks. It is designed to be mild on skin and eyes.
How it works
It reduces the surface tension between water and oil, allowing water to mix with and rinse away oily dirt and sebum. Because it is amphoteric, it remains gentle even at different pH levels and can boost foam in formulas without increasing irritation.
Pros
Extremely gentle on skin
This surfactant has a low irritation potential, making it ideal for sensitive skin, eczema-prone skin, and baby care products.
Works well in sulfate-free formulas
It helps create a satisfying lather without the harshness of sodium lauryl sulfate, so your cleanser feels effective but not stripping.
Cons and cautions
Synthetic origin
It is manufactured through chemical processes, which may be a drawback for consumers who prefer naturally derived or plant-only ingredients.
Potential for mild dryness in high concentrations
While generally mild, very high levels in a formula could still cause some dryness, especially for very dry or compromised skin.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Those who experience stinging or redness from sulfate-based cleansers
Use caution if
- Anyone seeking a completely natural or plant-derived ingredient list
