Ingredient review
TEA-Laureth Sulfate
INCI: TEA-Laureth Sulfate
A milder alternative to SLS that effectively cleanses without stripping the skin as harshly, but may still cause irritation for sensitive skin.
In plain English
TEA-Laureth Sulfate is a cleansing ingredient that helps shampoos and body washes foam up and remove dirt and oil. It's similar to the stronger Sodium Lauryl Sulfate (SLS) but is considered gentler because it's less stripping. However, it can still be drying or irritating for people with very sensitive or dry skin.

Quick decision guide
Useful, but context matters
TEA-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 TEA-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
TEA-Laureth Sulfate is a surfactant made by reacting lauryl alcohol with ethylene oxide and then sulfating it, neutralized with triethanolamine. It belongs to the sulfate family of cleansers.
How it works
It works by reducing the surface tension between water and oil, allowing water to mix with oils and dirt so they can be rinsed away. Its foaming action helps lift impurities from the skin and hair.
Pros
Gentler than SLS
TEA-Laureth Sulfate is less stripping than Sodium Lauryl Sulfate, making it a better choice for daily cleansing without over-drying.
Effective foaming
It produces a rich, satisfying lather that helps spread the product evenly and gives a sensory clean feel.
Cons and cautions
Potential irritation
Even though milder than SLS, it can still cause redness, itching, or dryness for those with sensitive skin, especially with frequent use.
Not sulfate-free
It is still a sulfate, so it may not be suitable for those seeking completely sulfate-free formulations for sensitive scalps or skin.
Best for
- People with normal to oily skin who want effective cleansing
- Those who tolerate mild sulfates well
Use caution if
- Individuals with very dry, sensitive, or compromised skin barriers
- Those with eczema or rosacea
Usage tips
Safety summary
Generally recognized as safe for use in rinse-off cosmetics at typical concentrations. Mild to moderate irritation potential exists, especially for sensitive individuals. Regulatory bodies set limits on residual 1,4-dioxane to ensure safety.
Research notes
Studies show TEA-Laureth Sulfate is less irritating than SLS but can still cause skin barrier disruption with prolonged exposure. It is considered safe for short-term, rinse-off use. More research is needed on long-term daily use on compromised skin.
Common label clues
- Typical concentration
- 1–15% in rinse-off products; lower in leave-on products
- Regulatory status
- Approved for use in cosmetics by the FDA and EU CosIng database within specified concentration limits. Manufacturers are required to minimize 1,4-dioxane contamination.
- Common uses
- Shampoos, Body washes, Facial cleansers, Bubble baths
- Environmental note
- As a surfactant, it may be slow to biodegrade in aquatic environments compared to some natural alternatives. However, modern wastewater treatment can reduce its impact.
Good to know
- TEA-Laureth Sulfate is often found in 'gentle' or 'mild' formulas but is not the same as truly sulfate-free cleansers.
- The 'Laureth' part indicates it has been ethoxylated, which can sometimes produce trace amounts of 1,4-dioxane during manufacturing, though levels are regulated.
