Ingredient review
TEA-PEG-3 Cocamide Sulfate
INCI: TEA-PEG-3 Cocamide Sulfate
A gentle, coconut-derived surfactant that helps create a rich lather without stripping the skin's natural moisture barrier.
In plain English
This ingredient is a mild cleansing agent made from coconut oil. It helps water mix with oil and dirt so they can be rinsed away, and it produces a nice foam. Because it's less harsh than some other cleansers, it's often used in products for sensitive or dry skin.

Quick decision guide
Useful, but context matters
TEA-PEG-3 Cocamide Sulfate 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 TEA-PEG-3 Cocamide Sulfate.
- 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
TEA-PEG-3 Cocamide Sulfate is a semi-synthetic surfactant created by reacting coconut oil derivatives with ethylene oxide and sulfuric acid, then neutralizing with triethanolamine. It belongs to the class of alkyl ether sulfates, known for their mildness.
How it works
In a cosmetic product, this molecule has a water-loving head and an oil-loving tail. When you lather up, the tails grab onto oils and dirt on your skin, while the heads stay in the water. Rinsing then washes away the whole complex, leaving skin clean.
Pros
Mild on skin
Compared to harsher sulfates like SLS, this ingredient is less likely to cause irritation or strip natural oils, making it suitable for daily use on normal to dry skin.
Good foam quality
It produces a dense, creamy lather that many people associate with a satisfying cleansing experience, without the tight feeling some cleansers leave behind.
Cons and cautions
Not for ultra-sensitive skin
While mild, it is still a sulfate-type surfactant. A small percentage of people with very reactive skin may experience slight tightness or dryness after repeated use.
Semi-synthetic origin
Because it undergoes chemical processing (ethoxylation), it is not considered a natural ingredient, which may be a concern for those seeking fully natural formulations.
Best for
- People with normal to dry skin looking for a gentle cleanser
- Anyone who prefers sulfate-based cleansers but wants a milder option than SLS
Use caution if
- Those with known allergies to coconut-derived ingredients or PEG compounds
Usage tips
Safety summary
TEA-PEG-3 Cocamide Sulfate is considered safe for use in rinse-off cosmetics at typical concentrations. It is less irritating than many other sulfates, though individuals with coconut allergies or extreme sensitivity should patch test first.
Research notes
Studies on related alkyl ether sulfates show low skin irritation and good biodegradability. Specific data on TEA-PEG-3 Cocamide Sulfate is limited, but its chemical class is well-characterized and supported by safety reviews.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and most major markets. The Cosmetic Ingredient Review (CIR) panel has evaluated similar alkyl ether sulfates and found them safe at typical concentrations.
- Common uses
- Shampoos, Body washes, Facial cleansers, Bubble baths
- Environmental note
- As a semi-synthetic surfactant, it is biodegradable under standard wastewater treatment conditions, but its production involves petrochemical-derived ethylene oxide.
Good to know
- This ingredient is often used alongside other mild surfactants like cocamidopropyl betaine to create a balanced cleansing system.
- The 'PEG-3' part indicates it has been ethoxylated, which improves water solubility and mildness.
