Ingredient review
Aminoethyl Sulfate
INCI: AMINOETHYL SULFATE
A mild synthetic surfactant that helps cleanse and adjust pH, but may cause irritation in sensitive skin at higher concentrations.
In plain English
Aminoethyl sulfate is a man-made ingredient used in shampoos and cleansers to help remove dirt and oil while also balancing the product's acidity. It is considered milder than some traditional sulfates like sodium lauryl sulfate, but it can still be drying or irritating for very sensitive skin if used too often.
Quick decision guide
Useful, but context matters
Aminoethyl 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 Aminoethyl 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
Aminoethyl sulfate is a synthetic compound that acts as a surfactant (cleansing agent) and pH adjuster. It is derived from ethanolamine and sulfuric acid, and is commonly used in personal care products to improve foam and cleansing ability.
How it works
In a cosmetic product, aminoethyl sulfate reduces the surface tension between water and oil, allowing dirt and excess sebum to be rinsed away. It also helps adjust the pH of the formula to be more compatible with skin and hair, which can reduce irritation compared to harsher surfactants.
Pros
Milder than traditional sulfates
Aminoethyl sulfate is less stripping than sodium lauryl sulfate, making it a better choice for daily cleansing without over-drying.
pH-balancing support
It helps keep the product's pH close to skin's natural level, which can reduce irritation and maintain a healthy barrier.
Cons and cautions
Potential irritation for sensitive skin
Even though it's milder, some people with very reactive skin may still experience redness or dryness with frequent use.
Limited research on long-term effects
Compared to more common surfactants, there is less published safety data specifically on aminoethyl sulfate, so its full profile is less understood.
Best for
- People with normal to oily hair or skin looking for a mild cleanser
- Those who want a sulfate alternative that is less harsh than SLS
Use caution if
- Individuals with very sensitive, eczema-prone, or damaged skin barriers
Usage tips
Safety summary
Aminoethyl sulfate is considered safe for use in cosmetics at typical concentrations. It is less irritating than many common sulfates, but individuals with very sensitive skin should patch test first. No serious health concerns have been reported in regulatory reviews.
Research notes
Available studies indicate low acute toxicity and moderate skin irritation potential. The Cosmetic Ingredient Review (CIR) has not published a specific monograph on aminoethyl sulfate, but similar sulfate esters are generally regarded as safe when used as directed.
Common label clues
- Typical concentration
- Typically 0.1–2% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions, with no specific restrictions at typical concentrations.
- Common uses
- Shampoos, Hair conditioners, Cleansing lotions
- Environmental note
- As a synthetic compound, its biodegradability is moderate; it is not known to be a major environmental concern at typical use levels.
Good to know
- Aminoethyl sulfate is not a true sulfate in the same family as SLS/SLES; it is a different chemical structure that is generally considered milder
- It is often used in combination with other surfactants to improve foam quality
