Ingredient review
Palmitoyl Glycine
INCI: Palmitoyl Glycine
Palmitoyl Glycine is a mild, amino-acid-based surfactant that cleanses without stripping the skin, making it a great choice for sensitive or dry skin types.
In plain English
Palmitoyl Glycine is a gentle cleansing ingredient made by combining palmitic acid (a fatty acid found in palm oil) with the amino acid glycine. It helps remove dirt and oil from the skin without being harsh or drying, and it also leaves a light conditioning feel. Because it's so mild, it's often used in products for sensitive skin.

Quick decision guide
Useful, but context matters
Palmitoyl Glycine 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 Glycine.
- 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 Glycine is a semi-synthetic compound formed by linking palmitic acid (a saturated fatty acid) with glycine (an amino acid). It functions as a mild surfactant and skin-conditioning agent.
How it works
As a surfactant, Palmitoyl Glycine lowers the surface tension between water and oil, allowing impurities to be rinsed away. Its amino-acid structure makes it less irritating than traditional sulfate-based cleansers, and it leaves a subtle moisturizing film on the skin.
Pros
Extremely gentle on skin
Palmitoyl Glycine has a low irritation risk, making it ideal for daily use on sensitive or compromised skin barriers.
Leaves skin conditioned
Unlike harsh cleansers that can strip natural oils, this ingredient helps maintain a soft, hydrated feel after washing.
Cons and cautions
Low foam production
If you enjoy a rich, bubbly lather, Palmitoyl Glycine may feel less satisfying than sulfate-based cleansers.
Palm oil sourcing concerns
Palmitic acid is often derived from palm oil, which can be associated with deforestation unless certified sustainable.
Best for
- People with sensitive, dry, or easily irritated skin
- Anyone looking for a sulfate-free, mild cleanser
Use caution if
- Those who prefer a high-foam, bubbly cleanser experience
Usage tips
Safety summary
Palmitoyl Glycine is considered safe for cosmetic use with very low irritation and sensitization potential. It is well-tolerated even by sensitive skin and is not known to be comedogenic.
Research notes
Amino-acid-based surfactants like Palmitoyl Glycine are well-documented in cosmetic science for their mildness and skin compatibility. While specific clinical studies on this exact compound are limited, the broader class is supported by dermatological consensus.
Common label clues
- Typical concentration
- 0.5% to 5% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics globally, including by the EU CosIng database and the US FDA as a cosmetic ingredient. No concentration restrictions are typically imposed.
- Common uses
- Facial cleansers, Body washes, Shampoos, Leave-on creams and lotions
- Environmental note
- Palmitoyl Glycine is biodegradable, but its palm oil source may raise environmental concerns. Look for products using RSPO-certified sustainable palm oil.
Good to know
- Palmitoyl Glycine is often used alongside other mild surfactants to balance cleansing and foam.
- It is not the same as palmitoyl oligopeptides, which are anti-aging peptides.
