Ingredient review
PPG-6 C12-18 Pareth-11
INCI: PPG-6 C12-18 Pareth-11
A mild synthetic emulsifier that helps cleansers rinse cleanly without stripping the skin.
In plain English
PPG-6 C12-18 Pareth-11 is a man-made ingredient that helps oil and water mix together in products like face washes and shampoos. It works by surrounding oil droplets so they can be rinsed away with water, leaving skin feeling clean but not overly dry. It is considered gentle and is often used in formulations that aim to be less irritating than traditional sulfates.

Quick decision guide
Useful, but context matters
PPG-6 C12-18 Pareth-11 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 PPG-6 C12-18 Pareth-11.
- 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, non-ionic surfactant and emulsifier derived from ethylene oxide and propylene oxide. It belongs to the 'pareth' family of cleansing agents.
How it works
It reduces the surface tension between oil and water, allowing oils and dirt to be lifted from the skin and rinsed away. Because it is non-ionic, it is less likely to strip the skin's natural moisture barrier compared to harsher anionic surfactants.
Pros
Gentle on skin
Non-ionic structure means it cleans without stripping the skin's natural oils, making it suitable for daily use.
Rinses cleanly
Leaves minimal residue, so skin feels fresh and not coated after washing.
Cons and cautions
Synthetic origin
Made from petrochemical derivatives, which may not align with clean-beauty or natural-product preferences.
Potential for irritation at high levels
While generally mild, very high concentrations or prolonged contact could still cause irritation for sensitive individuals.
Best for
- People with normal to combination skin looking for a gentle cleanser
- Those who prefer sulfate-free cleansing options
Use caution if
- Individuals with known sensitivity to ethoxylated ingredients
- Anyone seeking 100% natural or organic formulations
Usage tips
Safety summary
PPG-6 C12-18 Pareth-11 is considered safe for use in cosmetics at typical concentrations. It is a mild surfactant with low irritation and comedogenic potential. However, as with all ethoxylated ingredients, trace amounts of 1,4-dioxane (a byproduct) may be present, though levels are tightly regulated.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have found pareth-type surfactants to be safe in rinse-off products. No significant human or animal toxicity has been reported at cosmetic use levels.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. Generally recognized as safe when used as directed.
- Common uses
- Cleansers, Shampoos, Body washes, Makeup removers
- Environmental note
- Synthetic and petroleum-derived, but biodegradable. Environmental impact is lower than some harsher surfactants.
Good to know
- PPG-6 C12-18 Pareth-11 is considered biodegradable and is not classified as a known irritant by major cosmetic safety panels.
- It is often used as a milder alternative to sodium lauryl sulfate (SLS).
