PEG/PPG-160/30 Copolymer
INCI: PEG/PPG-160/30 Copolymer
A safe, synthetic thickener that helps create smooth, non-sticky gels and serums, but offers no direct skin benefit.
In plain English
PEG/PPG-160/30 Copolymer is a man-made ingredient that helps give skincare products a nice, gel-like texture. It thickens watery formulas so they feel more luxurious and spread easily, without leaving a sticky or greasy residue. Think of it like a food thickener for your lotion—it doesn't actively improve your skin, but it makes the product nicer to use.

Quick decision guide
Useful, but context matters
PEG/PPG-160/30 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-160/30 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 oxide (PEG) and propylene oxide (PPG). The numbers 160/30 refer to the ratio of these units, which determines its thickening and water-binding properties.
How it works
When added to water, the long polymer chains entangle and swell, increasing the viscosity of the solution. This creates a smooth, non-tacky gel that helps suspend other ingredients and improves the feel of the product on the skin.
Pros
Non-sticky feel
Creates a smooth, silky texture that doesn't leave a tacky residue, making it ideal for daytime serums and gels.
Versatile thickener
Works well across a wide pH range and with many other ingredients, giving formulators flexibility to create stable, elegant products.
Cons and cautions
No active benefit
This ingredient only improves texture and stability—it does not hydrate, exfoliate, or provide any direct skin benefit.
Synthetic origin
Made from petrochemicals, which may be a concern for those committed to natural or eco-friendly beauty routines.
Best for
- Anyone who enjoys lightweight, non-greasy gel textures
- People with oily or combination skin who prefer matte finishes
Use caution if
- Those seeking only natural or plant-derived ingredients
- Individuals with known sensitivity to PEG compounds (rare)
Usage tips
Safety summary
PEG/PPG-160/30 Copolymer is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential. Some consumers prefer to avoid PEG compounds due to manufacturing concerns, but purified cosmetic-grade versions are widely accepted as safe.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have concluded that PEG/PPG copolymers are safe in cosmetic formulations. No significant skin sensitization or toxicity has been reported in peer-reviewed studies at typical use levels.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics by the FDA and the European Commission. The Cosmetic Ingredient Review (CIR) panel has deemed PEG/PPG copolymers safe as used in cosmetics.
- Common uses
- Serums, Gels, Creams, Lotions, Hair styling 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 copolymers are widely used in cosmetics and are generally considered safe at typical concentrations.
- The 'PEG' part can sometimes be contaminated with impurities like ethylene oxide during manufacturing, but reputable brands use purified grades.
