Ingredient review
MEA-Laureth Sulfate
INCI: MEA-Laureth Sulfate
A milder alternative to SLS that still provides good foam, but may still be drying for very sensitive skin.
In plain English
MEA-Laureth Sulfate is a cleansing ingredient that helps water mix with oil and dirt so they can be rinsed away. It is similar to sodium laureth sulfate (SLES) but uses monoethanolamine to make it slightly gentler on the skin. You'll find it in many shampoos and body washes where it creates a rich lather without being as harsh as sodium lauryl sulfate (SLS).

Quick decision guide
Useful, but context matters
MEA-Laureth Sulfate can be useful, but watch for some irritation potential.
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 MEA-Laureth 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
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
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 synthetic surfactant made from lauryl alcohol (derived from coconut or palm oil) that has been ethoxylated and neutralized with monoethanolamine. It belongs to the sulfate family but is considered milder than SLS.
How it works
Its molecular structure has a water-loving head and an oil-loving tail. When you lather a product containing MEA-Laureth Sulfate, the tails grab onto oils and dirt while the heads pull them away into the rinse water, effectively cleansing the skin or hair.
Pros
Gentler than SLS
Compared to sodium lauryl sulfate, MEA-Laureth Sulfate is less likely to cause irritation or excessive dryness, making it a better choice for daily use.
Effective foamer
It produces a rich, satisfying lather that many people associate with a thorough clean, which can improve the user experience.
Cons and cautions
Still a sulfate
Despite being milder, it is still a sulfate surfactant and can strip the skin's natural moisture barrier if used too frequently or left on too long.
Potential for irritation
For those with compromised skin barriers or conditions like rosacea, even this milder sulfate may cause stinging, redness, or tightness.
Best for
- People with normal to oily skin or hair
- Those who prefer a foamy cleanser but want something gentler than SLS
Use caution if
- Individuals with very dry, eczema-prone, or severely sensitive skin
- Those following a sulfate-free routine for medical reasons
Usage tips
Safety summary
Generally recognized as safe for rinse-off cosmetic use at typical concentrations. Mild irritation is possible for sensitive individuals, but it is considered less harsh than SLS.
Research notes
Studies show that ethoxylated sulfates like MEA-Laureth Sulfate are less irritating than non-ethoxylated sulfates. However, long-term overuse can disrupt the skin barrier, especially in compromised skin.
Common label clues
- Typical concentration
- Typically 5–15% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions, with concentration limits typically set by industry guidelines.
- Common uses
- Shampoos, Body washes, Facial cleansers, Shower gels
- Environmental note
- As a synthetic surfactant, it may not be fully biodegradable in all aquatic environments; look for brands that use responsibly sourced palm derivatives.
Good to know
- MEA-Laureth Sulfate is often used in combination with other mild surfactants to reduce irritation further.
- It is not the same as sodium lauryl sulfate (SLS) — the 'laureth' form is always milder due to ethoxylation.
