Score terms in plain English
Irritation risk

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 (cleansing agent) made from fatty alcohols and ethylene oxide. It belongs to the 'pareth' family, which are known for their ability to reduce surface tension between oil and water.
How it works
It surrounds oil droplets and dirt particles on your skin, allowing them to be suspended in water and rinsed away. This action helps create a stable emulsion in creams and lotions, and boosts foam in cleansers.
Pros
Effective cleanser
Removes oil, makeup, and daily grime without leaving a heavy residue.
Formula-friendly
Helps create stable, smooth creams and lotions that don't separate.
Cons and cautions
Potential dryness
In high amounts or frequent use, it can strip natural oils, leading to tight or flaky skin.
Synthetic origin
Made from petrochemicals, which may be a concern for those seeking natural or eco-friendly options.
Best for
- People with normal to oily skin looking for effective cleansing
- Those who prefer lightweight, rinse-off products
Use caution if
- Individuals with very dry or compromised skin barriers
- Anyone seeking a completely natural ingredient list
Usage tips
Safety summary
Generally considered safe for use in rinse-off cosmetics at typical concentrations. Mild irritation or dryness is possible for sensitive individuals, especially with frequent use.
Research notes
Limited peer-reviewed studies specific to PPG-2 C9-11 Pareth-7, but the broader pareth family has been reviewed by safety panels (e.g., CIR) and found safe as used in cosmetics.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. Concentration limits apply in some countries for leave-on products.
- Common uses
- Cleansers, Shampoos, Body washes, Emulsions
- Environmental note
- Synthetic surfactants can be slow to biodegrade. Look for products with eco-friendly surfactant blends if this is a concern.
Good to know
- Often found in combination with other mild surfactants to reduce irritation.
- The 'PPG-2' part indicates a short polymer chain that makes it slightly milder than some other pareths.
