Ingredient review
PEG-7 Cocamide
INCI: PEG-7 Cocamide
A gentle, coconut-derived cleansing agent that helps products foam and rinse cleanly, but may not suit those avoiding ethoxylated ingredients.
In plain English
PEG-7 Cocamide is a mild cleansing ingredient made from coconut oil and a small amount of ethylene oxide. It helps cleansers and shampoos foam up nicely and rinse away dirt and oil without stripping the skin. Think of it as a helper that makes your face wash feel smooth and spread easily, while still being gentle enough for most skin types.

Quick decision guide
Useful, but context matters
PEG-7 Cocamide 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 PEG-7 Cocamide.
- 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
PEG-7 Cocamide is a semi-synthetic surfactant created by reacting coconut fatty acids with ethylene oxide. It belongs to the cocamide family and is valued for its mildness and ability to boost foam in rinse-off products.
How it works
It reduces the surface tension between water and oil, allowing dirt and excess sebum to be lifted away and rinsed off. Its PEG chain also helps stabilize formulas, keeping ingredients mixed and improving the product's texture.
Pros
Gentle on skin
PEG-7 Cocamide is considered low-irritation and suitable for daily use, even on sensitive skin, because it cleans without stripping natural oils.
Improves product feel
It boosts foam and gives cleansers a silky, spreadable texture, making your wash routine feel more luxurious and effective.
Cons and cautions
Ethoxylation concerns
As a PEG compound, it may contain trace amounts of 1,4-dioxane, a potential contaminant. Reputable brands purify their ingredients to minimize this risk.
Not fully natural
Despite being coconut-derived, the addition of ethylene oxide makes it semi-synthetic, which may not appeal to those seeking 100% natural skincare.
Best for
- People with normal to combination skin
- Anyone looking for a mild, coconut-derived cleanser
Use caution if
- Those with known sensitivities to PEG compounds
- Individuals seeking strictly natural or organic formulas
Usage tips
Safety summary
PEG-7 Cocamide is considered safe for cosmetic use at typical concentrations. The main concern is potential contamination with 1,4-dioxane, but reputable manufacturers purify the ingredient to meet safety standards. It is low-irritation and non-comedogenic for most people.
Research notes
The Cosmetic Ingredient Review (CIR) has evaluated similar cocamide surfactants and concluded they are safe in rinse-off products. No specific studies on PEG-7 Cocamide alone were found, but its chemical class is well-studied and widely used.
Common label clues
- Typical concentration
- 1–5% in rinse-off products
- Regulatory status
- Approved for cosmetic use in the EU, US, and many other regions. The Cosmetic Ingredient Review (CIR) panel has reviewed cocamide derivatives and found them safe at typical concentrations.
- Common uses
- Cleansers, Shampoos, Body washes, Facial washes
- Environmental note
- Derived from renewable coconut oil, but the ethoxylation process involves fossil-fuel-derived ethylene oxide. It is biodegradable in standard wastewater treatment conditions.
Good to know
- PEG-7 Cocamide is often used alongside other surfactants to reduce overall irritation
- It is biodegradable and commonly found in sulfate-free cleansers
