Ingredient review
Sodium Lauroamphoacetate
INCI: Sodium Lauroamphoacetate
A gentle, coconut-derived surfactant that effectively cleanses without stripping the skin's natural moisture barrier.
In plain English
Sodium lauroamphoacetate is a mild cleansing ingredient made from coconut oil. It helps remove dirt, oil, and makeup from your skin and hair without causing dryness or irritation. Unlike harsher detergents like sodium lauryl sulfate (SLS), this one is much gentler and often used in products for sensitive skin or babies. It works by attracting both water and oil, allowing impurities to be rinsed away easily.

Quick decision guide
Easy yes for most routines
Sodium Lauroamphoacetate 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 Lauroamphoacetate.
- 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 lauroamphoacetate is a semi-synthetic surfactant derived from lauric acid, a fatty acid found in coconut oil. It belongs to the class of amphoacetates, which are known for their mildness and compatibility with sensitive skin.
How it works
As a surfactant, it lowers the surface tension between water and oil, allowing the two to mix. This helps lift dirt, sebum, and other impurities from the skin and hair so they can be rinsed away with water. Its amphoteric nature (having both positive and negative charges) makes it gentle and less likely to strip the skin's natural oils.
Pros
Extremely gentle
One of the mildest surfactants available, making it ideal for sensitive skin and baby care products.
Moisture-friendly
Does not strip the skin's natural oils, helping to maintain a healthy moisture barrier.
Cons and cautions
Limited foaming
Produces a low, creamy lather rather than big bubbles, which some users may not prefer.
May need co-surfactants
Often combined with other surfactants to boost cleansing power, especially for oily skin or heavy makeup removal.
Best for
- People with sensitive or reactive skin
- Those looking for a gentle daily cleanser
- Individuals with dry or eczema-prone skin
Use caution if
- Those seeking a deep-cleansing or foaming experience without additional surfactants
