Ingredient review
PEI-14 PEG-10/PPG-7 Copolymer
INCI: PEI-14 PEG-10/PPG-7 Copolymer
A synthetic polymer that helps products spread smoothly and leaves a flexible, non-sticky film on skin or hair.
In plain English
This is a man-made ingredient that helps other ingredients spread evenly and stay put. It forms a thin, flexible film on your skin or hair, which can make products feel smoother and last longer without feeling heavy or sticky. Think of it like a gentle, invisible net that holds everything in place.

Quick decision guide
Useful, but context matters
PEI-14 PEG-10/PPG-7 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 PEI-14 PEG-10/PPG-7 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 made from polyethyleneimine (PEI) and polyethylene glycol (PEG) and polypropylene glycol (PPG) chains. It is designed to improve the texture and performance of cosmetic products.
How it works
When applied, it forms a thin, flexible film on the skin or hair surface. This film helps other ingredients adhere better, reduces water loss, and gives a smooth, non-tacky feel. It also helps stabilize emulsions and improve the spreadability of products.
Pros
Lightweight feel
Creates a flexible film that doesn't feel heavy or sticky, making it ideal for leave-in products and styling gels.
Improves product performance
Helps other active ingredients spread evenly and stay on the skin or hair longer, enhancing overall product efficacy.
Cons and cautions
Synthetic origin
Derived from petrochemicals, which may be a concern for those seeking natural or biodegradable ingredients.
Limited long-term data
While generally considered safe, there is less published research on the long-term effects of this specific copolymer compared to more common polymers.
Best for
- Anyone looking for a lightweight, non-sticky finish in hair or skincare
- People who use styling products and want flexible hold without stiffness
Use caution if
- Those who strictly avoid synthetic or PEG-based ingredients
Usage tips
Safety summary
Generally recognized as safe for topical use in cosmetics at typical concentrations. Low irritation and comedogenic potential. Those with very sensitive skin or strong preferences for natural ingredients may choose to avoid it.
Research notes
Limited peer-reviewed studies specifically on this copolymer, but similar PEG/PPG polymers have been extensively reviewed and are considered safe. The CIR panel has not raised significant concerns for this ingredient class.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has reviewed similar PEG/PPG copolymers and found them safe at typical use levels.
- Common uses
- Hair care products, Styling gels, Leave-in conditioners, Skincare formulations
- Environmental note
- As a synthetic polymer, it may not be readily biodegradable. However, it is used in low concentrations and is not known to accumulate in the environment.
Good to know
- This ingredient is often used in combination with other film-formers to achieve a specific texture or hold.
- It is considered safe by the Cosmetic Ingredient Review (CIR) panel when used in typical concentrations.
