Ingredient review
Sodium C12-14 Pareth-3 Sulfate
INCI: SODIUM C12-14 PARETH-3 SULFATE
A milder alternative to sodium lauryl sulfate that effectively cleanses but may still be drying for sensitive skin.
In plain English
Sodium C12-14 Pareth-3 Sulfate is a synthetic surfactant that helps water mix with oil and dirt so they can be rinsed away. It is chemically similar to sodium laureth sulfate but with a slightly different fatty chain length, which can make it a bit gentler on skin. It creates a rich lather and is commonly used in shampoos and body washes.

Quick decision guide
Useful, but context matters
Sodium C12-14 Pareth-3 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 Sodium C12-14 Pareth-3 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 anionic surfactant derived from coconut or palm fatty alcohols, ethoxylated and sulfated to improve mildness and foaming.
How it works
It reduces the surface tension between water and oil, allowing oils and dirt to be emulsified and washed away. Its ethoxylated chain makes it less irritating than non-ethoxylated sulfates like SLS.
Pros
Effective cleanser
Removes excess oil, makeup, and daily grime without requiring harsh scrubbing.
Milder than SLS
The ethoxylation makes it less irritating than sodium lauryl sulfate, so it's a common upgrade in gentler formulas.
Cons and cautions
Can be drying
Frequent use may strip the skin's natural moisture barrier, leading to tightness or flakiness.
Potential impurity concern
The manufacturing process can generate trace amounts of 1,4-dioxane, a possible carcinogen, though levels are regulated.
Best for
- People with normal to oily skin looking for effective cleansing
- Those who tolerate sulfate-based cleansers well
Use caution if
- Individuals with very dry, eczema-prone, or sensitive skin
- Those seeking a completely sulfate-free routine
Usage tips
Safety summary
Generally recognized as safe for rinse-off use at typical concentrations. Mild irritation possible for sensitive skin. Trace impurities are regulated to low levels.
Research notes
Studies show it is less irritating than sodium lauryl sulfate but can still disrupt the skin barrier with prolonged use. The Cosmetic Ingredient Review panel considers it safe as used.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics by the FDA and EU CosIng database, with concentration limits for rinse-off products.
- Common uses
- Facial cleansers, Body washes, Shampoos, Shower gels
- Environmental note
- Derived from petrochemicals or plant-based fatty alcohols; not readily biodegradable in all conditions, but less persistent than some older surfactants.
Good to know
- Often labeled as 'sodium pareth sulfate' on ingredient lists.
- Commonly found in sulfate-free shampoos as a gentler alternative to SLS.
