Ingredient review
Sodium C14-15 Pareth-PG Sulfonate
INCI: SODIUM C14-15 PARETH-PG SULFONATE
A gentle, sulfate-free surfactant that cleanses without stripping the skin's natural moisture barrier.
In plain English
This ingredient is a synthetic cleansing agent that helps water mix with oil and dirt so they can be rinsed away. Unlike harsher sulfates, it is designed to be milder on the skin, making it a popular choice for sensitive skin cleansers and baby products.

Quick decision guide
Useful, but context matters
Sodium C14-15 Pareth-PG Sulfonate 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-PG Sulfonate.
- 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
Sodium C14-15 Pareth-PG Sulfonate is a surfactant derived from fatty alcohols and ethylene oxide, modified with a sulfonate group to improve its cleansing and foaming properties while keeping irritation low.
How it works
It reduces the surface tension between water and oil, allowing impurities and excess sebum to be lifted from the skin and washed away. Its large molecular structure makes it less penetrating and therefore less irritating than smaller surfactants.
Pros
Gentle on skin
Its large molecular structure means it stays on the surface and doesn't penetrate, reducing irritation risk compared to traditional sulfates.
Good foam quality
Produces a rich, creamy lather that feels luxurious and effective without being overly stripping.
Cons and cautions
Synthetic origin
Made through chemical processing, which may not align with preferences for natural or minimal-ingredient routines.
Potential for dryness
If used alone or at high levels, it can still disrupt the skin barrier; it's often paired with milder co-surfactants.
Best for
- People with sensitive or easily irritated skin
- Those looking for a sulfate-free cleanser that still foams well
Use caution if
- Individuals who prefer exclusively natural or plant-derived ingredients
- Those with known allergies to ethoxylated compounds (rare)
Usage tips
Safety summary
Sodium C14-15 Pareth-PG Sulfonate is considered safe for use in cosmetics at typical concentrations. It has low irritation and sensitization potential, making it a well-tolerated choice for sensitive skin.
Research notes
Studies and safety reviews by the Cosmetic Ingredient Review (CIR) panel have found alkyl ether sulfonates to be safe in rinse-off and leave-on products when formulated correctly. No significant systemic toxicity or carcinogenicity has been reported.
Common label clues
- Typical concentration
- 1–10% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics globally, including by the FDA (US) and EU CosIng database, with no concentration restrictions for rinse-off products.
- Common uses
- Facial cleansers, Body washes, Shampoos, Shower gels
- Environmental note
- Biodegradable under standard conditions, but its ethoxylate chain means it may require specific wastewater treatment for full breakdown.
Good to know
- This surfactant is often used in 'sulfate-free' formulas as a gentler alternative to SLS/SLES.
- It is biodegradable and considered safe for aquatic environments at typical use levels.
