Ingredient review
Sodium Methyl 2-Sulfolaurate
INCI: SODIUM METHYL 2-SULFOLAURATE
A gentle, coconut-derived surfactant that cleans effectively without stripping the skin, ideal for sensitive or dry skin types.
In plain English
Sodium Methyl 2-Sulfolaurate is a mild cleansing ingredient made from coconut oil. It helps remove dirt, oil, and makeup without stripping your skin's natural moisture barrier. Unlike harsh soaps, it creates a soft, creamy lather and rinses cleanly, leaving skin feeling comfortable rather than tight or dry.

Quick decision guide
Easy yes for most routines
Sodium Methyl 2-Sulfolaurate 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 Sodium Methyl 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 taurine (an amino acid). It belongs to the class of sulfonate surfactants, known for their mildness and excellent foaming properties.
How it works
It works by reducing the surface tension between water and oil, allowing dirt and sebum to be lifted away and rinsed off. Its molecular structure is large and gentle, so it doesn't penetrate deeply into the skin, minimizing irritation.
Pros
Extremely gentle on skin
Its large molecular structure means it doesn't easily penetrate the skin barrier, reducing the risk of irritation and dryness compared to traditional sulfates like SLS.
Eco-friendly profile
Made from renewable coconut oil and fully biodegradable, it aligns with sustainable and green beauty standards.
Cons and cautions
Moderate cleansing power
While great for daily use, it may not thoroughly remove heavy waterproof makeup or long-wear sunscreen without a double cleanse.
Potential for slight residue
In some formulations, it can leave a very light film on the skin, which might feel unusual for those used to squeaky-clean rinses.
Best for
- People with sensitive, dry, or eczema-prone skin
- Those looking for a sulfate-free cleanser
Use caution if
- Individuals with known allergies to coconut-derived ingredients (rare)
Usage tips
Safety summary
Sodium Methyl 2-Sulfolaurate is considered very safe for cosmetic use. It has low irritation and sensitization potential, and no significant health concerns have been reported in standard use concentrations.
Research notes
Research supports its mildness compared to traditional sulfates. Studies show it causes less protein loss from skin and hair, and its biodegradability is well-documented. However, long-term human safety studies are limited, as is typical for most cosmetic surfactants.
Common label clues
- Typical concentration
- 1–15% in rinse-off products
- Regulatory status
- Approved for use in cosmetics by the FDA and EU CosIng database. Generally recognized as safe when used as directed.
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby care products
- Environmental note
- Derived from coconut oil, a renewable resource, and readily biodegradable, making it a more environmentally friendly choice compared to petroleum-based surfactants.
Good to know
- Often used alongside other mild surfactants like Cocamidopropyl Betaine to improve foam quality and skin feel.
- It is considered a 'sulfate-free' surfactant, but the name can be confusing—it is not the same as sodium lauryl sulfate (SLS).
