Ingredient review
Sodium Cocoyl Glycinate
INCI: Sodium Cocoyl Glycinate
A mild, coconut-derived cleanser that effectively removes dirt and oil without stripping the skin's natural moisture barrier.
In plain English
Sodium cocoyl glycinate is a gentle cleansing ingredient made from coconut oil and the amino acid glycine. It helps create a soft, creamy lather that washes away makeup, sweat, and excess oil without leaving your skin feeling tight or dry. Unlike harsher soaps, it respects your skin's natural pH and is less likely to cause irritation, making it a favorite in sensitive-skin and baby-friendly formulas.

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 Cocoyl Glycinate.
- 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 cocoyl glycinate is a surfactant, meaning it helps water mix with oil and dirt so they can be rinsed away. It is produced by reacting fatty acids from coconut oil with glycine, an amino acid naturally found in the body. This gives it a mild, skin-friendly profile that cleanses without disrupting the skin's protective barrier.
How it works
In a cleanser, sodium cocoyl glycinate molecules have one end that attracts water and another that attracts oil. When you lather and rinse, these molecules surround and lift away dirt, sebum, and makeup from your skin's surface. Because it is an amino acid-based surfactant, it has a pH close to that of healthy skin (around 5.5), so it cleans gently without over-drying.
Pros
Extremely gentle on skin
Its amino acid base means it cleans without disrupting the skin's moisture barrier, reducing the risk of tightness or irritation after washing.
pH-balanced formula
It naturally maintains a pH close to skin's ideal range (around 5.5), helping to keep the acid mantle intact and prevent dryness.
Cons and cautions
Less effective on heavy makeup
If you wear long-wearing or waterproof cosmetics, you may need an oil-based pre-cleanse first, as this surfactant alone may not dissolve them completely.
Higher cost than sulfates
Products formulated with sodium cocoyl glycinate tend to be pricier than those using traditional sulfates like sodium lauryl sulfate.
Best for
- People with dry or sensitive skin looking for a non-stripping cleanser
- Those who prefer sulfate-free or amino acid-based cleansing products
Use caution if
- Individuals seeking a deep-cleansing formula for heavy, waterproof makeup may need a double-cleanse routine
Usage tips
Safety summary
Sodium cocoyl glycinate is widely regarded as safe and non-irritating for topical use. It has a low irritation and comedogenic risk, making it suitable for sensitive and acne-prone skin. No significant safety concerns have been reported in cosmetic concentrations.
Research notes
Studies and dermatological reviews confirm that amino acid-based surfactants like sodium cocoyl glycinate are milder than traditional anionic surfactants, with less disruption to skin barrier function and lower irritation potential. Evidence is moderate but consistent across cosmetic science literature.
Common label clues
- Typical concentration
- 5-15% in rinse-off cleansers
- Regulatory status
- Approved for use in cosmetics globally, including by the U.S. FDA and EU CosIng database, with no known restrictions at typical use levels.
