Laureth-12 Succinate
INCI: LAURETH-12 SUCCINATE
A gentle synthetic surfactant that helps cleanse without over-drying, but offers no active skincare benefits beyond cleaning.
In plain English
Laureth-12 Succinate is a man-made cleansing ingredient that helps water mix with oil and dirt so they can be rinsed away. It is considered milder than traditional sulfates like SLS, making it a good option for sensitive skin that still wants effective cleansing.

Quick decision guide
Useful, but context matters
Laureth-12 Succinate 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-12 Succinate.
- 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-12 Succinate is a synthetic surfactant derived from lauryl alcohol and succinic acid. It belongs to the class of anionic surfactants, meaning it has a negative charge that helps lift grime and oil from the skin and hair.
How it works
In a cosmetic product, Laureth-12 Succinate reduces the surface tension between water and oil, allowing them to blend. This creates a gentle foam that traps dirt and oil, which is then easily rinsed away without stripping the skin's natural moisture barrier.
Pros
Gentle on skin
Laureth-12 Succinate is less irritating than many traditional sulfates, making it a good choice for daily use on sensitive or reactive skin.
Effective cleanser
It efficiently removes excess oil, makeup, and environmental debris without leaving a tight or stripped feeling.
Cons and cautions
Limited research
Compared to more common surfactants like cocamidopropyl betaine, there is less published safety and efficacy data for this specific ingredient.
Potential for dryness
While mild, it can still be drying for very dry or compromised skin if used in high concentrations or without complementary moisturizing ingredients.
Best for
- People with normal to combination skin looking for a mild daily cleanser
- Those who prefer sulfate-free cleansing options
Use caution if
- Individuals with very dry or eczema-prone skin should patch test first, as even mild surfactants can be drying over time
Usage tips
Safety summary
Laureth-12 Succinate is considered safe for use in rinse-off cosmetics at typical concentrations. It has low irritation and comedogenic potential, but individuals with very sensitive or dry skin should patch test first.
Research notes
Research on Laureth-12 Succinate specifically is limited, but it belongs to a well-studied class of anionic surfactants. General safety data for similar laureth-based ingredients supports its use as a mild cleanser.
Common label clues
- Typical concentration
- Typically 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. The Cosmetic Ingredient Review (CIR) has evaluated similar laureth compounds and found them safe at typical use concentrations.
- Common uses
- Facial cleansers, Body washes, Shampoos, Makeup removers
- Environmental note
- As a synthetic surfactant, its biodegradability may vary. Look for products from brands that prioritize eco-friendly formulations if this is a concern.
Good to know
- Laureth-12 Succinate is often used in 'sulfate-free' cleansers as a primary or secondary surfactant.
- It is not known to be comedogenic, so it is generally safe for acne-prone skin.
