Ingredient review
Sodium Palmitoyl Glutamate
INCI: SODIUM PALMOYL GLUTAMATE
A gentle, skin-friendly surfactant that cleanses without stripping the skin barrier.
In plain English
Sodium Palmitoyl Glutamate is a mild cleansing ingredient made from coconut oil and an amino acid called glutamic acid. It helps remove dirt, oil, and makeup without leaving your skin feeling tight or dry. Unlike harsh soaps, it respects your skin's natural moisture barrier, making it a favorite for sensitive or dry skin types.

Quick decision guide
Easy yes for most routines
Sodium Palmitoyl Glutamate 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 Palmitoyl Glutamate.
- 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 Palmitoyl Glutamate is a surfactant, meaning it helps water mix with oil and dirt so they can be rinsed away. It belongs to the family of amino-acid-based cleansers, which are known for being much gentler than traditional sulfates. It is produced by combining palmitic acid (from coconut or palm oil) with glutamic acid (an amino acid) and then neutralizing it with sodium.
How it works
When you wash your face, this ingredient lowers the surface tension of water, allowing it to trap oily impurities and lift them off your skin. Its molecular structure has a water-loving head and an oil-loving tail, so it can surround and suspend dirt and sebum. Because it has a pH close to your skin's natural pH (around 5.5), it cleanses without disrupting the acid mantle or causing irritation.
Pros
Extremely gentle on skin
Unlike sodium lauryl sulfate, this surfactant has a low irritation potential and a pH close to skin's natural level, making it ideal for daily use even on compromised barriers.
Supports skin barrier health
Because it doesn't over-strip natural oils, it helps maintain the skin's moisture balance and reduces the risk of dryness or tightness after washing.
Cons and cautions
Lower foam volume
It produces a creamy, low-to-moderate lather rather than big, fluffy bubbles. Some users accustomed to sulfate-based cleansers may feel it doesn't 'clean' as thoroughly, though it does.
Higher cost
Amino-acid surfactants are more expensive to produce than conventional sulfates, so products containing them often come with a higher price tag.
Best for
- People with dry, sensitive, or eczema-prone skin
- Anyone looking for a sulfate-free, gentle cleanser
Use caution if
- Those who prefer a very high-foam, bubbly cleanser (though it still lathers moderately)
Usage tips
Safety summary
Sodium Palmitoyl Glutamate is considered very safe for cosmetic use. It has a low irritation and sensitization profile, and no significant toxicity concerns have been reported in standard concentrations. It is not known to be comedogenic.
Research notes
Amino-acid-based surfactants like Sodium Palmitoyl Glutamate are well-documented in dermatological literature as milder alternatives to traditional anionic surfactants. Studies show they cause less protein denaturation and lipid extraction from the skin, supporting barrier integrity.
Common label clues
- Typical concentration
- 1–15% in rinse-off products; lower in leave-on formulations
- Regulatory status
- Approved for cosmetic use globally, including by the FDA (as a generally recognized safe ingredient in cosmetics) and under EU cosmetic regulations.
- Common uses
- Facial cleansers, Body washes, Shampoos, Makeup removers
- Environmental note
- Derived from coconut or palm oil and glutamic acid; palm oil sourcing can raise sustainability concerns, but many brands use certified sustainable palm oil.
Good to know
- Sodium Palmitoyl Glutamate is often combined with other mild surfactants to improve foam and cleansing power.
- It is considered biodegradable and is derived from renewable plant sources, making it a more sustainable choice.
