Ingredient review
PPG-1-PEG-9 Lauryl Glycol Ether
INCI: PPG-1-PEG-9 LAURYL GLYCOL ETHER
A gentle synthetic emulsifier that helps mix oil and water in cleansers and conditioners, with a low risk of irritation.
In plain English
This ingredient is a man-made helper that allows oil and water to blend together in products like face washes and shampoos. It's part of a family of ingredients called surfactants, which help lift dirt and oil from your skin and hair so they can be rinsed away. Because it's designed to be mild, it's less likely to cause stinging or dryness compared to harsher cleansers.

Quick decision guide
Useful, but context matters
PPG-1-PEG-9 Lauryl Glycol Ether 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-1-PEG-9 Lauryl Glycol Ether.
- 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
PPG-1-PEG-9 Lauryl Glycol Ether is a synthetic polymer made from propylene glycol (PPG) and polyethylene glycol (PEG) chains attached to a lauryl (coconut-derived) alcohol. It functions as a non-ionic surfactant and emulsifier.
How it works
In a cosmetic product, this ingredient sits at the boundary between oil and water droplets, reducing surface tension so they can mix into a stable emulsion. During cleansing, it helps break down sebum and makeup, allowing them to be rinsed away without stripping the skin's natural moisture barrier.
Pros
Mild on skin
This surfactant is designed to be gentle, making it suitable for daily use without causing tightness or irritation.
Versatile formulator
It works well in both rinse-off and leave-on products, helping create smooth, stable textures in cleansers, conditioners, and lotions.
Cons and cautions
Synthetic origin
As a lab-made ingredient, it may not appeal to consumers seeking exclusively natural or plant-based formulations.
Potential processing impurities
PEG-based ingredients can sometimes contain trace levels of ethylene oxide or 1,4-dioxane if not properly purified, though reputable manufacturers control for this.
Best for
- People with normal to combination skin
- Those looking for a mild daily cleanser
Use caution if
- Individuals with known sensitivity to PEG compounds (rare)
Usage tips
Safety summary
PPG-1-PEG-9 Lauryl Glycol Ether is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential. The main concern is theoretical contamination from manufacturing, which is well-controlled by reputable suppliers.
Research notes
Safety assessments for PEG/PPG ethers are based on decades of use and reviews by expert panels like the CIR. No significant human toxicity or sensitization has been reported at cosmetic levels.
Common label clues
- Typical concentration
- Usually 0.5% to 5% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. The Cosmetic Ingredient Review (CIR) panel has reviewed similar PEG ethers and found them safe at typical use levels.
- Common uses
- Cleansers, Shampoos, Conditioners, Body washes
- Environmental note
- As a synthetic polymer, it may not be readily biodegradable. However, its low use concentration means environmental impact is generally considered low.
Good to know
- This ingredient is often found in sulfate-free cleansers as a gentler alternative to sodium lauryl sulfate.
- The 'lauryl' part comes from coconut or palm oil, making it partially plant-derived.
