PEG/PPG-30/160 Copolymer
INCI: PEG/PPG-30/160 Copolymer
A safe, synthetic thickener that gives water-based products a silky feel without clogging pores.
In plain English
PEG/PPG-30/160 Copolymer is a synthetic ingredient that helps give skincare products a smooth, non-sticky texture. It works by thickening the formula and creating a thin, flexible film on the skin. This makes it common in lightweight gels and serums where you want a silky feel without greasiness. It is generally well-tolerated and unlikely to cause irritation or breakouts.

Quick decision guide
Useful, but context matters
PEG/PPG-30/160 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-30/160 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 30 and 160 refer to the average number of repeating units in each block, which determines its thickening and film-forming properties.
How it works
When added to a water-based formula, the polymer chains entangle and increase the viscosity, creating a gel-like consistency. Upon application, it spreads easily and dries down to a thin, flexible film that helps other ingredients stay on the skin longer.
Pros
Non-comedogenic
Unlikely to clog pores, making it suitable for acne-prone skin.
Smooth texture
Creates a silky, spreadable gel that feels lightweight and refreshing on the skin.
Cons and cautions
Synthetic origin
Derived from petrochemicals, which may be a concern for those seeking natural or organic products.
Potential tackiness
At high concentrations, it can leave a slightly sticky or tacky residue on the skin.
Best for
- Anyone who prefers lightweight, gel-based moisturizers or serums
- People with oily or combination skin who want a matte finish
Use caution if
- Those who strictly avoid synthetic ingredients in their routine
Usage tips
Safety summary
PEG/PPG-30/160 Copolymer is considered safe for topical use in cosmetics at typical concentrations. It has low irritation and comedogenic potential. The main safety concern is potential contamination with ethylene oxide during manufacturing, but cosmetic-grade ingredients are purified to meet safety standards.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have concluded that PEG/PPG copolymers are safe for use in cosmetics. No significant human or animal studies indicate toxicity or irritation at typical use levels.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and other major markets. The Cosmetic Ingredient Review (CIR) panel has deemed PEG/PPG copolymers safe as used in cosmetics.
- Common uses
- Serums, Gels, Moisturizers, Hair Styling Products
- Environmental note
- As a synthetic polymer, it is not biodegradable and may accumulate in the environment. However, it is used in small amounts in rinse-off products.
Good to know
- PEG/PPG copolymers are often used in combination with other thickeners to fine-tune texture.
- The 'PEG' part can be contaminated with ethylene oxide during manufacturing, but cosmetic-grade versions are purified to safe levels.
