Ingredient review
Laureth-2 Acetate
INCI: Laureth-2 Acetate
Laureth-2 Acetate is a gentle synthetic surfactant that helps cleanse without over-drying, making it a good option for sensitive skin.
In plain English
Laureth-2 Acetate is a mild cleansing ingredient made from lauryl alcohol and ethylene oxide, modified with an acetate group to make it even gentler. It helps water mix with oil and dirt so they can be rinsed away, but it's designed to be less harsh than traditional sulfates. You'll find it in cleansers and shampoos that aim to clean without stripping your skin's natural moisture barrier.

Quick decision guide
Useful, but context matters
Laureth-2 Acetate 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 Laureth-2 Acetate.
- 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
Laureth-2 Acetate is a synthetic surfactant (cleansing agent) derived from lauryl alcohol. It belongs to the laureth family, which are ethoxylated alcohols, but the acetate modification reduces its potential for irritation, making it a milder alternative to common sulfates like SLS.
How it works
In a cosmetic product, Laureth-2 Acetate lowers the surface tension between water and oil, allowing the product to lift away sebum, makeup, and environmental debris. Its acetate group makes it less aggressive on the skin's lipid barrier compared to non-modified laureths, so it cleans effectively while minimizing dryness or tightness.
Pros
Mild on skin
Laureth-2 Acetate is designed to clean without disrupting the skin barrier, making it suitable for daily use on sensitive or dry skin.
Good lather
It produces a pleasant, creamy foam that helps spread the product evenly, enhancing the user experience in shampoos and body washes.
Cons and cautions
Potential trace impurities
As an ethoxylated ingredient, it may contain trace amounts of 1,4-dioxane (a potential carcinogen) if not properly purified, though reputable brands ensure low levels.
Sustainability concerns
Often derived from palm oil, which can be linked to deforestation unless sourced from certified sustainable suppliers.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Anyone who prefers sulfate-free or low-irritation cleansing products
Use caution if
- Those with known allergies to ethoxylated ingredients (rare)
Usage tips
Safety summary
Laureth-2 Acetate is considered safe for cosmetic use at typical concentrations. The main concern is potential trace 1,4-dioxane from ethoxylation, but reputable manufacturers purify to meet safety limits. It is generally non-irritating and non-comedogenic.
Research notes
Research on laureth compounds indicates low irritation potential compared to traditional sulfates. The CIR panel has reviewed similar ethoxylated alcohols and deemed them safe. No specific studies on Laureth-2 Acetate were found, but its chemical class is well-characterized.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. The Cosmetic Ingredient Review (CIR) panel has reviewed related laureth compounds and found them safe at typical concentrations.
- Common uses
- Cleansers, Shampoos, Body washes, Facial washes
- Environmental note
- As a synthetic surfactant, it may have moderate biodegradability. Brands using sustainably sourced palm oil can reduce environmental impact.
Good to know
- Laureth-2 Acetate is considered a 'sulfate-free' alternative, but it's still a synthetic surfactant.
- The '2' in its name refers to the average number of ethylene oxide units, which influences its mildness.
