Sodium Lauroamphopropionate
INCI: Sodium Lauroamphopropionate
A gentle, low-irritation surfactant that effectively cleanses while being kinder to sensitive skin than traditional sulfates.
In plain English
Sodium Lauroamphopropionate is a mild cleansing ingredient often found in gentle face washes and body cleansers. It helps lift dirt, oil, and makeup from your skin without leaving it feeling tight or dry. Unlike harsher detergents like sodium lauryl sulfate, this surfactant is known for being less irritating, making it a popular choice for sensitive or dry skin types. It works by attracting both water and oil, allowing impurities to be rinsed away easily.

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 Lauroamphopropionate.
- 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 Lauroamphopropionate is a synthetic, amphoteric surfactant derived from lauric acid (a fatty acid found in coconut or palm oil) and modified with amino acid-like structures. It belongs to the class of amphoacetates and is valued for its mildness and compatibility with other cleansing agents.
How it works
In a cosmetic product, this surfactant reduces the surface tension between water and oil, allowing them to mix. This helps break down sebum, dirt, and makeup on the skin so they can be washed away with water. Because it is amphoteric (carries both positive and negative charges), it is less likely to strip the skin's natural moisture barrier compared to anionic surfactants like sulfates.
Pros
Very gentle on skin
This surfactant is one of the mildest cleansing agents available, making it ideal for daily use on sensitive or reactive skin without causing tightness or irritation.
Helps preserve moisture barrier
Unlike harsher detergents, it cleans without stripping away too many natural oils, helping your skin stay hydrated and comfortable after washing.
Cons and cautions
Lower foam than sulfates
It produces a less rich, creamy lather compared to sodium lauryl sulfate, which may feel less satisfying to those who prefer a bubbly cleanser.
Synthetic production
Although derived from natural fatty acids, the final ingredient is chemically processed, which may not align with preferences for entirely natural or minimally processed ingredients.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Those who prefer sulfate-free or low-foam cleansing products
Use caution if
- Individuals with known allergies to coconut-derived ingredients (rare, but possible)
Usage tips
Safety summary
Sodium Lauroamphopropionate is widely regarded as safe for use in cosmetics. It has a low irritation and sensitization potential, making it suitable for sensitive skin. As with any ingredient, patch testing is recommended for those with known allergies to coconut-derived compounds.
Research notes
