Ingredient review
PEG/PPG-17/6 Copolymer
INCI: PEG/PPG-17/6 Copolymer
A gentle, water-attracting polymer that helps products feel smooth and spread easily without irritation.
In plain English
PEG/PPG-17/6 Copolymer is a synthetic ingredient made from chains of ethylene glycol and propylene glycol. It acts like a sponge that pulls water into the skin, keeping it hydrated, while also helping other ingredients mix together and spread smoothly. You'll often find it in lightweight serums and moisturizers where it adds a silky, non-greasy feel.

Quick decision guide
Useful, but context matters
PEG/PPG-17/6 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-17/6 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 copolymer composed of polyethylene glycol (PEG) and polypropylene glycol (PPG) units, designed to be water-soluble and skin-friendly.
How it works
It works by attracting and holding moisture from the air or product onto the skin's surface, acting as a humectant. Its polymer structure also helps stabilize formulas and improve the texture, making products feel lighter and more spreadable.
Pros
Lightweight hydration
Attracts moisture to the skin without leaving a heavy or sticky residue, making it ideal for daytime use or humid climates.
Improves product feel
Helps serums and creams spread evenly and smoothly, enhancing the overall sensory experience of your skincare routine.
Cons and cautions
Synthetic origin
As a lab-made ingredient, it may not appeal to those seeking exclusively natural or plant-based formulations.
Potential tackiness at high levels
In very high concentrations or on extremely dry skin, it can feel slightly sticky until fully absorbed.
Best for
- People with normal to oily skin looking for lightweight hydration
- Anyone who prefers non-greasy, fast-absorbing skincare textures
Use caution if
- Those with known sensitivities to PEG compounds (rare)
Usage tips
Safety summary
PEG/PPG-17/6 Copolymer has a low irritation and comedogenic risk, making it suitable for most skin types. It is well-tolerated and rarely causes allergic reactions. As with all PEG compounds, there is a theoretical concern about potential contamination with ethylene oxide or 1,4-dioxane during manufacturing, but reputable brands ensure these impurities are removed to safe levels.
Research notes
Research on PEG/PPG copolymers focuses on their safety and functionality as humectants and texture enhancers. Studies indicate they are non-irritating and non-sensitizing at typical cosmetic concentrations. Evidence is moderate, with most data coming from ingredient safety reviews rather than large-scale clinical trials.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has deemed PEG/PPG copolymers safe at typical use levels.
- Common uses
- Serums, Moisturizers, Cleansers, Hair products
- Environmental note
- As a synthetic polymer, it is not biodegradable and may persist in the environment. However, it is used in low concentrations and is not considered a major environmental concern.
Good to know
- PEG/PPG-17/6 Copolymer is considered safe for use in cosmetics by major regulatory bodies when used as directed.
- It is often used in combination with other humectants like glycerin to boost overall hydration.
