Ingredient review
Sodium C14-15 Pareth-8 Carboxylate
INCI: Sodium C14-15 Pareth-8 Carboxylate
A gentle synthetic surfactant that effectively cleanses without stripping the skin's natural moisture barrier.
In plain English
This is a man-made cleansing ingredient that helps water mix with oil and dirt so they can be rinsed away. It is known for being milder than traditional soaps, making it a good choice for sensitive or dry skin. You'll find it in many gentle face washes and body cleansers.

Quick decision guide
Useful, but context matters
Sodium C14-15 Pareth-8 Carboxylate 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 Sodium C14-15 Pareth-8 Carboxylate.
- 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
A synthetic surfactant derived from fatty alcohols and ethylene oxide, modified with a carboxylate group to improve mildness and compatibility with skin.
How it works
It lowers the surface tension between water and oil, allowing the product to lift away sebum, makeup, and impurities. Its large molecular structure makes it less penetrating and therefore less irritating than harsher cleansers like sodium lauryl sulfate.
Pros
Very mild on skin
Its large molecular structure means it stays on the surface and doesn't penetrate deeply, reducing irritation risk.
Effective yet gentle cleanser
It removes dirt, oil, and makeup without leaving the skin feeling tight or dry.
Cons and cautions
Synthetic origin
It is manufactured in a lab, which may not align with preferences for naturally derived ingredients.
Potential for slight drying at high levels
In very high concentrations, it could still disrupt the skin barrier, though this is uncommon in well-formulated products.
Best for
- People with dry or sensitive skin
- Those looking for a gentle daily cleanser
Use caution if
- Individuals who strictly avoid synthetic ingredients
- Those with known allergies to ethoxylated compounds (rare)
Usage tips
Safety summary
Sodium C14-15 Pareth-8 Carboxylate is considered safe for use in cosmetics at typical concentrations. It has low irritation and sensitization potential, making it suitable for sensitive skin. No significant safety concerns have been raised by regulatory bodies.
Research notes
Research on alkyl ether carboxylates shows they are mild surfactants with good cleansing properties. Studies indicate low skin irritation and eye irritation potential compared to traditional sulfates. The evidence is based on ingredient class reviews rather than ingredient-specific clinical trials.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and most major markets. The Cosmetic Ingredient Review (CIR) panel has reviewed similar alkyl ether carboxylates and found them safe as used.
- Common uses
- Facial cleansers, Body washes, Shampoos, Makeup removers
- Environmental note
- Biodegradable under standard conditions, but as a synthetic compound it requires energy and chemical processing to produce.
Good to know
- Often used in 'sulfate-free' cleansers as a primary or secondary surfactant.
- It is considered biodegradable and safe for aquatic life at typical use levels.
