Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.

What it is
Sodium Peanutamphoacetate is a surfactant (a type of cleansing agent) produced by reacting peanut fatty acids with amino acids. It belongs to the amphoacetate family, known for being exceptionally mild on skin and eyes.
How it works
In a cosmetic product, this ingredient works by reducing the surface tension of water, allowing it to mix with oil and dirt so they can be rinsed away. Its amphoteric nature means it can work well in both acidic and alkaline formulas, and it helps create a rich, creamy lather while being gentle enough for sensitive skin.
Pros
Very gentle on skin
Unlike harsher sulfates, this surfactant cleanses without stripping the skin's natural moisture barrier, making it ideal for dry or sensitive skin types.
Pleasant lather
It produces a creamy, rich foam that feels luxurious during cleansing, enhancing the user experience without compromising gentleness.
Cons and cautions
Peanut allergy concern
Because it is derived from peanut oil, people with peanut allergies may experience a reaction. Always check with your doctor if you have severe allergies.
Less common in formulations
It is not as widely used as other mild surfactants, so product options may be limited compared to more popular alternatives.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Those who prefer mild, non-stripping surfactants in their daily routine
Use caution if
- Individuals with a known peanut allergy should avoid products containing this ingredient
Usage tips
Safety summary
Sodium Peanutamphoacetate is considered safe for use in cosmetics at typical concentrations. The main safety consideration is its peanut origin, which could trigger allergic reactions in sensitive individuals. For most people, it is a gentle, low-irritation ingredient.
Research notes
