Methoxy PEG-22/Dodecyl Glycol Copolymer
INCI: METHOXY PEG-22/DODECYL GLYCOL COPOLYMER
A synthetic polymer that helps products spread smoothly, feel silky, and stay put without clogging pores.
In plain English
This is a man-made ingredient that helps your skincare and makeup products feel nice on your skin. It works like a gentle glue that holds the formula together, helps it spread evenly, and leaves a smooth, non-greasy finish. Think of it as a helper that makes your lotion or sunscreen feel silky and stay where you put it.

Quick decision guide
Useful, but context matters
Methoxy PEG-22/Dodecyl Glycol 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 Methoxy PEG-22/Dodecyl Glycol 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 polyethylene glycol (PEG) and dodecyl glycol. It is a large molecule that acts as a film former and emulsifier in cosmetic formulations.
How it works
When applied to the skin, it forms a thin, flexible film that helps other ingredients stay in place and improves the texture of the product. As an emulsifier, it helps water and oil mix together so the product doesn't separate. It also gives a silky, smooth feel to the skin without being sticky or greasy.
Pros
Silky, non-greasy feel
Leaves a smooth, velvety finish on the skin without the heavy or sticky feeling some other ingredients can cause.
Helps products stay stable
Acts as an emulsifier to keep oil and water mixed, so your product stays consistent and effective from first use to last.
Cons and cautions
Synthetic origin
Made in a lab, so it may not appeal to those seeking all-natural or organic skincare products.
Potential for trace impurities
Like other PEG compounds, it can contain trace amounts of ethylene oxide or 1,4-dioxane if not properly purified, though reputable brands ensure high-quality sourcing.
Best for
- Anyone looking for a lightweight, non-greasy moisturizer or sunscreen
- People with oily or combination skin who want a matte finish
Use caution if
- Those who strictly avoid synthetic or PEG-based ingredients
- People with known sensitivities to PEG compounds (rare)
Usage tips
Safety summary
Generally considered safe for use in cosmetics at typical concentrations. The main concern is the potential for trace impurities from manufacturing, but modern purification processes keep these levels very low. It has low irritation and comedogenic risk.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have reviewed similar PEG polymers and found them safe for cosmetic use. There is limited specific research on this exact copolymer, but its chemical class is well-studied and considered low-risk.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has evaluated similar PEG polymers and found them safe at typical use levels.
- Common uses
- Moisturizers, Sunscreens, Makeup, Hair styling products, Serums
- Environmental note
- As a synthetic polymer, it is not biodegradable and may persist in the environment. However, it is used in small amounts and is not considered a major environmental concern compared to microplastics.
Good to know
- This ingredient is often found in 'silky' or 'velvet' texture products.
- It is considered safe by major cosmetic safety panels when used as intended.
