Ingredient review
Sodium C12-14 Sec-Pareth-8 Carboxylate
INCI: SODIUM C12-14 SEC-PARETH-8 CARBOXYLATE
A gentle synthetic cleanser that effectively removes impurities while being kinder to the skin barrier than traditional sulfates.
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's designed to be milder than common sulfates like SLS, meaning it's less likely to leave your skin feeling tight or dry. You'll find it in many gentle face washes and body cleansers.

Quick decision guide
Useful, but context matters
Sodium C12-14 Sec-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 C12-14 Sec-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 make it milder and more conditioning.
How it works
It reduces the surface tension between water and oil, allowing dirt, sebum, and makeup to be emulsified and washed away. Its secondary (sec-) structure and carboxylate group make it less penetrating and less irritating than primary surfactants.
Pros
Mild on skin
Its chemical structure makes it less irritating than many common sulfates, so it's a good choice for daily cleansing without disrupting the skin barrier.
Effective cleanser
It still removes oil, makeup, and dirt efficiently, so you don't have to sacrifice performance for gentleness.
Cons and cautions
Synthetic origin
It is manufactured through chemical processes, which may not align with preferences for naturally derived or 'clean' ingredients.
Potential for slight dryness
In high concentrations or without balancing ingredients, it can still cause some dryness, especially for very dry or compromised skin.
Best for
- People with dry or sensitive skin
- Anyone looking for a sulfate-free cleanser
Use caution if
- Those who prefer exclusively natural ingredients
- Individuals with known allergies to ethoxylated compounds (rare)
Usage tips
Safety summary
Sodium C12-14 Sec-Pareth-8 Carboxylate is considered safe for use in rinse-off cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for sensitive skin. As with any surfactant, avoid eye contact and discontinue use if irritation occurs.
Research notes
Research on this specific surfactant is limited, but it belongs to a well-studied class of mild carboxylate surfactants. Studies on similar secondary ethoxylated surfactants show low skin irritation and good biodegradability. It is not associated with significant health or environmental concerns.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No specific restrictions beyond general surfactant safety guidelines.
- Common uses
- Facial cleansers, Body washes, Shampoos, Makeup removers
- Environmental note
- Synthetic but generally biodegradable; check product formulation for overall environmental impact.
Good to know
- This ingredient is often part of a blend with other mild surfactants to optimize foam and gentleness.
- It is considered biodegradable and safe for aquatic life at typical use levels.
