Ingredient review
Palmitoyl Glutamic Acid
INCI: Palmitoyl Glutamic Acid
A mild, amino-acid-based surfactant that cleanses without stripping the skin’s natural moisture barrier.
In plain English
Palmitoyl glutamic acid is a gentle cleansing ingredient made by combining a fatty acid (palmitic acid) with an amino acid (glutamic acid). It helps remove dirt, oil, and makeup from your skin without causing tightness or irritation. Because it is less harsh than traditional sulfates, it is a popular choice for sensitive or dry skin types.

Quick decision guide
Useful, but context matters
Palmitoyl Glutamic Acid 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 Palmitoyl Glutamic Acid.
- 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
Palmitoyl glutamic acid is a synthetic surfactant derived from palmitic acid (a common saturated fat) and glutamic acid (an amino acid). It belongs to the family of acyl glutamates, which are known for their mild cleansing properties.
How it works
In a cleanser, palmitoyl glutamic acid acts as a surfactant: its fatty tail grabs oil and dirt, while its water-loving head allows them to be rinsed away with water. It forms a stable lather but is much gentler on the skin’s lipid barrier than sodium lauryl sulfate or other strong detergents.
Pros
Very gentle on skin
Palmitoyl glutamic acid has a low irritation risk, making it ideal for sensitive or reactive skin that reacts poorly to harsher cleansers.
Supports moisture balance
Unlike sulfates that can strip natural oils, this surfactant helps preserve the skin’s barrier, reducing post-cleansing tightness and dryness.
Cons and cautions
Mild cleansing power
It may not thoroughly remove heavy, long-wear makeup or sunscreen in a single wash, so a double-cleansing routine might be needed.
Higher cost
Products formulated with amino-acid surfactants tend to be pricier than those using conventional sulfates, which can be a drawback for budget-conscious shoppers.
Best for
- People with dry, sensitive, or eczema-prone skin
- Anyone looking for a sulfate-free, gentle daily cleanser
Use caution if
- Those who prefer a high-foam, squeaky-clean feel may find it too mild
Usage tips
Safety summary
Palmitoyl glutamic acid is considered safe for use in cosmetics at typical concentrations. It has a low irritation and comedogenic risk, making it suitable for sensitive skin. No significant safety concerns have been reported in regulatory reviews.
Research notes
Amino-acid-based surfactants, including palmitoyl glutamic acid, have been studied for their mildness and skin compatibility. Research indicates they cause less disruption to the skin barrier compared to sodium lauryl sulfate. However, direct clinical studies on this specific compound are limited.
Common label clues
- Typical concentration
- 1–10% in rinse-off cleansers; lower in leave-on products
- Regulatory status
- Approved for use in cosmetics globally, including by the EU CosIng database and the US FDA (as part of generally recognized safe surfactant categories).
- Common uses
- Facial cleansers, Body washes, Shampoos, Micellar waters
- Environmental note
- Acyl glutamates like palmitoyl glutamic acid are generally biodegradable and have a lower aquatic toxicity profile than many traditional surfactants.
Good to know
- Palmitoyl glutamic acid is often combined with other mild surfactants to boost foam and cleaning power.
- It is considered biodegradable and is commonly used in eco-friendly formulations.
