Ingredient review
Sodium Palmamphoacetate
INCI: Sodium Palmamphoacetate
A gentle, low-irritation surfactant that effectively cleanses without stripping the skin's natural moisture barrier.
In plain English
Sodium Palmamphoacetate is a mild cleansing ingredient derived from palm kernel oil. It belongs to a class of surfactants called amphoacetates, which are known for being very gentle on skin and eyes. Unlike harsher cleansers like sodium lauryl sulfate, this ingredient cleans without leaving skin feeling tight or dry. It's often found in products for sensitive skin, baby washes, and gentle facial cleansers because it removes dirt and oil while helping maintain the skin's natural moisture balance.

Quick decision guide
Useful, but context matters
Sodium Palmamphoacetate 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 Palmamphoacetate.
- 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 Palmamphoacetate is a semi-synthetic surfactant made by reacting palm kernel fatty acids with amino acid-like compounds. It is a mild, amphoteric surfactant, meaning it can work in both acidic and alkaline conditions, making it versatile in cleanser formulations.
How it works
In a cosmetic product, this ingredient reduces the surface tension of water, allowing it to mix with oil and dirt on the skin. It surrounds and lifts away impurities so they can be rinsed off easily. Because of its amphoteric nature, it is less likely to disrupt the skin's protective barrier compared to harsher anionic surfactants.
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.
Moisture-friendly cleansing
Unlike sulfates, it cleans without stripping natural oils, helping to keep the skin barrier intact and reducing dryness.
Cons and cautions
Palm oil sourcing concerns
Derived from palm kernel oil, which may be associated with deforestation if not sourced sustainably. Look for RSPO-certified products.
Mild cleansing power
May not thoroughly remove heavy makeup, waterproof sunscreen, or very oily residues, requiring a double-cleansing step.
Best for
- People with dry or sensitive skin who find other cleansers too harsh
- Anyone looking for a gentle, everyday facial or body cleanser
Use caution if
- Those who prefer completely palm-oil-free products (look for coconut-derived alternatives)
Usage tips
Safety summary
Sodium Palmamphoacetate is considered safe for use in cosmetics. It has low skin and eye irritation potential and is not known to be sensitizing. No significant safety concerns have been raised by regulatory bodies.
Research notes
Studies on amphoacetate surfactants, including Sodium Palmamphoacetate, show they are among the mildest cleansing agents available, with minimal disruption to the skin barrier. They are widely used in formulations for sensitive skin and baby care.
Common label clues
- Typical concentration
- 5–15% in rinse-off cleansers
- Regulatory status
- Approved for use in cosmetics in the EU, US, and most global markets. No known restrictions at typical concentrations.
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby care products
- Environmental note
- Derived from palm kernel oil; choosing products with RSPO-certified palm oil can help reduce environmental impact.
Good to know
- Sodium Palmamphoacetate is often combined with other mild surfactants to improve foam and cleansing performance.
- It is considered a 'green' surfactant because it is biodegradable and derived from natural oils.
