Ingredient review
PPG-2 C12-13 Pareth-8
INCI: PPG-2 C12-13 PARETH-8
A synthetic cleansing agent that helps remove dirt and oil, but may be drying for sensitive or dry skin types.
In plain English
PPG-2 C12-13 Pareth-8 is a man-made ingredient that helps water and oil mix together, so it's often used in cleansers and shampoos to lift away dirt and makeup. Think of it as a gentle helper that breaks down greasy residues so they can be rinsed away easily. However, because it's a surfactant, it can sometimes strip the skin of its natural oils, leading to dryness if used too often or in high amounts.

Quick decision guide
Useful, but context matters
PPG-2 C12-13 Pareth-8 can be useful, but watch for some irritation potential.
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-2 C12-13 Pareth-8.
- 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
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
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 ethylene oxide and propylene oxide reacted with a fatty alcohol chain. It belongs to the 'pareth' family of ingredients, which are known for their ability to reduce surface tension and help water mix with oils.
How it works
It works by surrounding oil and dirt particles, breaking them into tiny droplets that can be washed away with water. This makes it effective at removing sebum, sunscreen, and makeup without requiring harsh scrubbing.
Pros
Effective oil removal
Breaks down sebum and makeup efficiently, making it great for double-cleansing routines.
Improves product feel
Helps create a smooth, non-greasy texture in cleansers and lotions.
Cons and cautions
Potential for dryness
Overuse or high concentrations can strip natural oils, leading to tightness or flakiness.
Moderate irritation risk
May cause stinging or redness in sensitive skin, especially around the eyes.
Best for
- People with normal to oily skin looking for effective cleansing
- Those who wear heavy makeup or waterproof sunscreen and need a thorough cleanse
Use caution if
- Individuals with very dry, sensitive, or compromised skin barriers
Usage tips
Safety summary
Generally considered safe for use in cosmetics at typical concentrations. The main concern is skin dryness or irritation, especially for sensitive skin types. Eye irritation is possible. Always patch test new products.
Research notes
Studies on pareth-type surfactants show they are effective cleansers with moderate irritation potential. The Cosmetic Ingredient Review (CIR) panel has reviewed similar ethoxylated alcohols and found them safe when formulated to minimize irritation.
Common label clues
- Typical concentration
- 1–10% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. No specific restrictions at typical use levels.
- Common uses
- Cleansers, Shampoos, Body washes, Makeup removers
- Environmental note
- As a synthetic ethoxylate, it may have moderate biodegradability. Some formulations may contain trace levels of 1,4-dioxane, a byproduct of ethoxylation, though reputable manufacturers purify to low levels.
Good to know
- This ingredient is often found in sulfate-free cleansers as a milder alternative to SLS.
- It is not considered comedogenic, so it's unlikely to clog pores.
