Disodium Cocoyl Glutamate
INCI: DISODIUM COCOYL GLUTAMATE
A mild, coconut-derived surfactant that cleanses effectively while being gentle enough for sensitive skin.
In plain English
Disodium cocoyl glutamate is a cleansing ingredient made from coconut oil and the amino acid glutamic acid. It works like a gentle soap, lifting away dirt and oil from your skin without causing dryness or irritation. Because it's derived from natural sources and has a low irritation potential, it's a popular choice in products for sensitive or dry 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 Disodium Cocoyl 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
A surfactant (cleansing agent) produced by reacting fatty acids from coconut oil with glutamic acid, an amino acid naturally found in the body.
How it works
It reduces the surface tension between water and oil, allowing impurities to be rinsed away. Its molecular structure is mild on the skin barrier, so it cleans without over-stripping natural oils.
Pros
Very gentle on skin
Unlike harsh sulfates, this surfactant cleans without stripping the skin's natural oils, making it ideal for daily use and sensitive skin.
Environmentally friendly
Derived from renewable plant sources and biodegradable, it has a lower environmental impact compared to many synthetic surfactants.
Cons and cautions
Less foaming than sulfates
It produces a creamy, low lather rather than big bubbles, which some users may not prefer if they associate foam with cleanliness.
Potential for mild dryness at high levels
In very high concentrations, it can still be slightly drying, though much less so than traditional cleansers.
Best for
- People with sensitive or reactive skin
- Those seeking a gentle, sulfate-free cleanser
- Individuals with dry or eczema-prone skin
Use caution if
- Anyone with a known allergy to coconut-derived ingredients
