Ingredient review
Coceth-7
INCI: COCETH-7
A gentle, coconut-derived cleansing agent that helps remove dirt and oil without stripping the skin.
In plain English
Coceth-7 is a mild cleansing ingredient made from coconut oil. It helps water mix with oil and dirt so they can be rinsed away easily. Because it's gentle, it's often used in products for sensitive or dry skin, but it can still be drying if used in high amounts or without other moisturizing ingredients.

Quick decision guide
Useful, but context matters
Coceth-7 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 Coceth-7.
- 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
Coceth-7 is a semi-synthetic surfactant and emulsifier created by reacting coconut oil with ethylene oxide. It belongs to a group of ingredients called PEG (polyethylene glycol) derivatives, which help oil and water blend together in cleansers and creams.
How it works
In a cosmetic product, Coceth-7 reduces the surface tension between water and oil, allowing them to mix. This helps lift makeup, sunscreen, and excess sebum from the skin so they can be washed away with water. It also helps stabilize emulsions, keeping creams and lotions from separating.
Pros
Gentle cleanser
Coceth-7 is much milder than traditional sulfates like SLS, making it suitable for daily use without over-stripping the skin.
Coconut-derived
Sourced from coconut oil, it appeals to those seeking plant-based cleansing alternatives, though it is chemically modified.
Cons and cautions
Potential for drying
Even though it's mild, Coceth-7 can still remove natural oils, so those with very dry skin may need a richer moisturizer afterward.
PEG concerns
As a PEG compound, there are purity concerns regarding potential contamination with 1,4-dioxane during manufacturing, though reputable brands ensure it is purified.
Best for
- People with normal to oily skin looking for a gentle cleanser
- Those who prefer coconut-derived ingredients over harsher sulfates
Use caution if
- Individuals with very dry or eczema-prone skin may find it slightly drying
- Anyone with a known sensitivity to PEG compounds
Usage tips
Safety summary
Coceth-7 is considered safe for use in cosmetics at typical concentrations. The main concern is potential contamination with 1,4-dioxane during production, but reputable manufacturers purify the ingredient to meet safety standards. It has low irritation and comedogenic potential for most skin types.
Research notes
Research on Coceth-7 specifically is limited, but it is similar to other PEG-based surfactants that have been reviewed by the Cosmetic Ingredient Review panel. Studies show that PEG compounds are generally safe and well-tolerated when properly purified. No significant toxicity or sensitization has been reported in cosmetic use.
Common label clues
- Typical concentration
- 1% to 10% in rinse-off products; lower in leave-on products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. The Cosmetic Ingredient Review (CIR) panel has reviewed PEG compounds and found them safe when properly purified.
- Common uses
- Cleansers, Shampoos, Body washes, Makeup removers
- Environmental note
- Coceth-7 is derived from renewable coconut oil and is biodegradable, but the ethoxylation process uses ethylene oxide, which has environmental and safety considerations in manufacturing.
Good to know
- Coceth-7 is often listed as PEG-7 Cocoglycerides on ingredient labels.
- It is considered biodegradable and more environmentally friendly than some petroleum-based surfactants.
