PEG/PPG-10/30 Copolymer
INCI: PEG/PPG-10/30 Copolymer
A safe, synthetic thickener that improves product texture without clogging pores or causing irritation.
In plain English
PEG/PPG-10/30 Copolymer is a man-made ingredient that helps skincare products feel smooth and spread easily. It works by thickening watery formulas and helping oil and water mix together, so your lotion or serum has a nice, even consistency. Think of it as a helper that makes your product feel silky and not too runny or sticky.

Quick decision guide
Useful, but context matters
PEG/PPG-10/30 Copolymer 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 PEG/PPG-10/30 Copolymer.
- 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 polymer made from repeating units of ethylene glycol (PEG) and propylene glycol (PPG). The numbers 10 and 30 refer to the average number of repeating units in each block, which determines its water-loving and oil-loving balance.
How it works
In a cosmetic product, this copolymer acts as a thickener by increasing the viscosity of water-based solutions. It also helps stabilize emulsions (mixtures of oil and water) so they don't separate. On the skin, it leaves a light, non-greasy film that improves the feel of the product without being heavy or sticky.
Pros
Improves texture
Makes watery serums and lotions feel smooth and silky, so they glide on easily without pilling.
Low irritation risk
Rarely causes stinging or redness, making it suitable for sensitive skin when used at typical levels.
Cons and cautions
Synthetic origin
Made from petrochemicals, which some people prefer to avoid in their skincare routine.
Can feel tacky at high levels
If used in very high concentrations, it may leave a slightly sticky or film-like feel on the skin.
Best for
- Anyone who wants a lightweight, non-greasy moisturizer or serum
- People with oily or combination skin who dislike heavy textures
Use caution if
- Those who strictly avoid all synthetic ingredients
