Ingredient review
Perfluorononyl Octyldodecyl Glycol Meadowfoamate
INCI: PERFLUORONONYL OCTYLDODECYL GLYCOL MEADOWFOAMATE
A high-tech emollient that provides water resistance and a silky feel, but its environmental persistence raises concerns.
In plain English
This ingredient is a lab-made molecule that combines a fluorinated (water-repelling) part with a fatty acid from meadowfoam seed oil. In skincare, it creates a thin, breathable film on the skin that helps other ingredients stay put and gives a smooth, non-greasy feel. It's often used in sunscreens and long-wear makeup to improve water resistance and spreadability.

Quick decision guide
Useful, but context matters
Perfluorononyl Octyldodecyl Glycol Meadowfoamate 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 Perfluorononyl Octyldodecyl Glycol Meadowfoamate.
- 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
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A semi-synthetic ester formed by reacting perfluorononyl octyldodecyl glycol (a fluorinated alcohol) with meadowfoam fatty acids. The result is a molecule with both water-repelling (fluorinated) and skin-conditioning (ester) properties.
How it works
When applied, it spreads into an even, invisible film that resists water and sweat. This film helps active ingredients (like sunscreen filters) stay on the skin longer and reduces the need for frequent reapplication. It also imparts a silky, velvety feel without heavy oiliness.
Pros
Excellent water resistance
Helps sunscreens and makeup stay put longer, even during swimming or sweating, so you don't have to reapply as often.
Silky, lightweight feel
Spreads easily and leaves a smooth, velvety finish without greasiness, making it ideal for lightweight moisturizers and primers.
Cons and cautions
Environmental persistence
Fluorinated compounds like this one can break down very slowly in the environment, raising concerns about long-term ecological impact.
Limited safety data
There is less published research on this specific ingredient compared to more common emollients, so its long-term safety profile is not fully established.
Best for
- People who want long-wearing, water-resistant sunscreens or makeup
- Those who prefer a silky, lightweight feel in moisturizers
Use caution if
- Individuals with very sensitive or reactive skin (due to limited data)
- Anyone seeking fully biodegradable or eco-friendly formulations
Usage tips
Safety summary
Generally considered safe for topical use at typical concentrations, but long-term safety data is limited. The main concern is environmental persistence rather than direct skin toxicity.
Research notes
Published studies on this specific ingredient are scarce. Most evidence comes from manufacturer data and general knowledge of fluorinated esters. More independent research is needed to fully assess its safety and environmental impact.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US and EU, but specific restrictions may apply in some regions due to concerns about fluorinated compounds.
- Common uses
- Moisturizers, Sunscreens, Long-wear foundations, Water-resistant products
- Environmental note
- Fluorinated ingredients are generally not biodegradable and can accumulate in the environment. Some regulatory bodies are reviewing their use in consumer products.
Good to know
- This ingredient is not water-soluble and requires proper emulsification in water-based formulas.
- It is often used in combination with other silicones and esters to fine-tune texture.
