Ingredient review
Sodium Ethyl 2-Sulfolaurate
INCI: SODIUM ETHYL 2-SULFOLAURATE
A gentle, coconut-derived surfactant that cleanses effectively without the harshness of traditional sulfates.
In plain English
Sodium Ethyl 2-Sulfolaurate is a mild cleansing agent made from coconut oil and lauric acid. It helps create a nice lather in cleansers and shampoos while being much gentler on the skin than sodium lauryl sulfate (SLS). It removes dirt, oil, and makeup without stripping away your skin's natural moisture barrier.

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 Ethyl 2-Sulfolaurate.
- 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 semi-synthetic surfactant derived from lauric acid (found in coconut oil) and ethanol. It belongs to the sulfosuccinate family and is known for its mildness.
How it works
It works by reducing the surface tension between water and oil, allowing dirt and sebum to be rinsed away. Its large molecular structure makes it less penetrating into the skin, which reduces irritation compared to harsher sulfates.
Pros
Gentle on skin
Its large molecular structure means it doesn't penetrate deeply, reducing the risk of irritation and making it suitable for sensitive skin types.
Eco-friendly profile
Derived from renewable coconut oil and biodegradable, it aligns with sustainable beauty preferences without sacrificing performance.
Cons and cautions
Lower foam volume
Compared to SLS, it produces a less voluminous lather, which may disappoint users who equate foam with cleansing power.
Potential for slight dryness
In high concentrations or for very dry skin, it can still remove some natural oils, so pairing with moisturizing ingredients is recommended.
Best for
- People with normal to combination skin looking for a gentle daily cleanser
- Those who want a sulfate-free alternative that still foams well
Use caution if
- Individuals with extremely dry or eczema-prone skin may still find it slightly drying; consider a non-foaming cleanser instead
Usage tips
Safety summary
Sodium Ethyl 2-Sulfolaurate is considered safe for cosmetic use with low irritation and comedogenic potential. It is well-tolerated by most skin types, though patch testing is recommended for those with known sensitivities.
